The MP-3874 Mixer Coils can be used with the LC-SSX1 heat exchanger as well as the LC-066SS liquid cooler. The mixer coils are made from stainless steel, so they are capable of being used with high purity or corrosive fluids. In applications where the flow rate is low or the fluid is more viscous that water, the resulting performance of the heat exchanger is reduced. The mixer coils help stir up the water to improve the heat transfer.

Depending on the application’s flow rate and desired fluid temperature, the mixer coils can be an inexpensive way to improve the heat pumping capacity of the cooler and avoid having to use a larger, more expensive cooler or multiple coolers.

• 316 stainless steel mixer coils is ideal for many types of liquids which are otherwise not compatible with anodized aluminum or copper.

• Two mixer coils are included in each set to provide full coverage in the LC-SSX1 heat exchanger tubing.

• When used with water, the mixer coils can be helpful with flow rates less then 1.5 L/min.

Installation is simple. One end of the mixer coil is flared. Just insert the non-flared end of the coil into the inlet or outlet, feed the mixer into the tube and then secure the mixer by compressing the flared end until it fits inside the tube. The resulting tension when installed in the tube keeps it in place. Once in the tube we recommend that the mixer is pressed in until the flared section is approximately even to the aluminum body of the heat exchanger.

This sensor features a high accuracy interchangeable tolerance corresponding to ±0.1°C over 0°C to 70°C. It has a small 0.9mm diameter, 6.35 mm long cylindrical head. The resistance is 15K ohms at @ 25 °C (TS-67/ 15K-1 curve). This temperature sensor provides a measurement range of -20 °C to +100 °C and works with all of our temperature controllers. The thermistor can be mounted in a hole or on a surface.

Wire is 32 gauge solid, overall length is 152 mm. The wires have a thin varnish insulation (similar to magnet wire) and are not terminated. Although delicate, these thin wires have an advantage in that they do not conduct much heat into the measurement head of the sensor, and they are easy to preheat or precool. This helps ensure accurate temperature measurements. We do recommend that if you will be bending the wire leads against a sharp metallic edge (such as when exiting a sensor hole) the wires be protected with a thin layer of epoxy or heat shrink so the edge does not cut through the varnish and electrically short the sensor. Of course, you can radius to the sharp edge so it will not abrade the varnish.

Typically, a larger diameter wire is added to this thermistor as an extension to increase the overall distance from controller to measurement point. The wire leads can be extended with standard copper wire of any gauge recommended for the controllers (no special alloy necessary). The sensor does not have “fast-on” spade connectors on the end, so you must add wire and connectors if you wish to use this thermistor with the TC-24-10.

The AC-055 thermoelectric (Peltier) air cooler is specially designed for cooling electronics enclosures when a large temperature difference from ambient is not required. While not specifically designed for refrigeration it can be used in these applications as long as a large temperature difference below ambient is not required. It can, as with all of our coolers, both heat and cool when used with the proper temperature controller.

The AC-055 is environmentally protected: the hot-side fan is sealed against moisture and dust (IP55), the external heat sink is anodized to prevent corrosion, and the finger guards are stainless steel. The unit is rated to maintain an enclosure’s NEMA 4 rating.

A low-profile internal fan minimizes the amount of internal volume required by the cooler. Internal air is pulled primarily through one end of the fins and blown out the fan towards the center of the enclosure. This configuration allows one end of the internal fins to be placed close to the wall of the enclosure without hindering performance, and the equipment that needs the most cooling can be located in the cooled air stream.

The AC-055 is powered by 12 VDC and works with all of our temperature controllers. If more capacity is needed, or there is a need to distribute the cooling throughout a larger cabinet, multiple coolers can be paralleled and regulated by one temperature controller. The electrical connections are located on the internal side of the cooler keeping wiring inside the enclosure. (Care should be taken so that condensation is not allowed to form on the cold side heat exchanger where it could come in contact with the power wires.)

The AC-055’s low power consumption yields low operating costs. As an added benefit the power supply will generate less waste heat, meaning the power supply has less of an impact when located inside the enclosure.

Note: Larger power supplies are used when controlling multiple units with one temperature controller.

A four-module cold plate for cooling medium to large heat loads. Provides effective direct-contact cooling or heating (up to 100 °C) which is ideal for precision temperature control.

This cooler uses two fans in parallel to push air through the length of the fins. This gives a different option for routing air flow as compared to a more standard configuration where air is blown onto the top middle of the fins and is exhausted at the ends of the fins. The fan configuration also reduces stack height in the system and means the cooler can be placed directly on a bench top without restricting air flow. The fans were selected to give good performance while being as quiet as possible–good for people who have to work next to the cooler as it is operating.

Like all of our coolers, it can be easily customized for OEM users to meet your production requirements: special cold plates, smaller heat sinks, different operating voltages, lower power consumption, et cetera.

• Heat sink air travels along the length of fins (in one end, out opposite end).
• Low fan noise is beneficial in laboratory instrumentation (two fans; each rated at 39 dBA each).

The AC-220 provides high cooling capacity in a narrow 150 mm wide (5.9″) package. The overall dimensions are compact making it easy to get significant cooling capacity in a small space. The cooler is powered by 24 VDC and is rated to maintain the enclosure’s NEMA 4 rating. The AC-220 is protected against harsh environments via an anodized external heat sink, stainless steel hardware, and an IP-68 rated external fan. The external fan is also speed controllable and has a tachometer output signal. Like all cooling assemblies from TE Technology (and unlike many coolers from competitive companies) the thermoelectric/Peltier elements have our epoxy potting and the assembly is sealed to reduce moisture ingress inside the cooler.

The AC-220 can also be used for heating, and two over-temperature thermostats are incorporated in the cooler (one on each set of fins). The thermostats are intended to provide a separate means of over-temperature protection for the cooler and equipment and can be monitored via the interlock feature on a TC-720 temperature controller or used to control the output inhibit line on a PS-24-25 power supply. Please note these thermostats are NOT intended as a means of temperature control for the cooler or for direct switching of high-current loads.

Finally, as with all TE Technology coolers it can also be customized with other features if production quantities are needed.

The TC-36-25-RS232-UL does not come with a thermistor or RS-232 cable; they must be ordered separately. Six (6) crimp on connectors are included with the TC-36-25-RS232-UL.

APPLICATION
The TC-36-25-RS232-UL provides bi-directional temperature control for thermoelectric devices, either independently or with supplemental resistive heaters for both cooling and heating applications. The controller uses solid-state MOSFET devices in an electrical “H” bridge configuration to automatically control the direction of current simply based on the temperature set point.

The controller can be communicated with and programmed directly through a personal computer’s RS232 serial communication port. The supplied communications software,

compatible with Windows 10, 8, 7, provides a graphical user interface; no prior programming experience is required to use it. However, the command set is provided so that qualified personnel can use it is as an embedded control or can create a custom program interface using LabVIEW, for example.

An alternate LabVIEW based GUI available as a download (see downloads page), and the source code for that is available upon request. That download includes the LabVIEW Runtime Engine, so the LabVIEW application is not required to run the software. A sample read and write command programmed in Python (2.7) is also available for download from the SOFTWARE tab on this web page.

Once the desired controller parameters are established, the settings can be saved to non-volatile memory. The TC-36-25-RS232-UL can then be disconnected from the computer and operated as a unique, stand alone controller. The controller can also be configured to use a variety of analog inputs to adjust the set point.

Mechanically, the controller’s printed circuit board is mounted to a metal bracket that is suitable for either horizontal or vertical orientation. The controller can operate in ambient temperatures from 0 C up to 60 C without generally requiring additional heat sinking.

TECHNICAL DESCRIPTION

Low voltage TE device control capability. The TC-36-25-RS232-UL requires an input voltage anywhere from 12 V up to 36 V. That voltage powers the microprocessor and can also be modulated and sent to the thermoelectric device. However, if the thermoelectric cooler or Peltier device operates on a voltage lower than 12 V, a second low-voltage power supply can be connected. The controller will then switch this voltage on and off to the TE device. The second input voltage can range anywhere from 0 V to 36 V.
High resolution and Stability. The output signal to the thermoelectric cooler is pulse-width modulated (PWM) at 2700 Hz. The PWM control scheme affords temperature resolution of 0.01 C or 0.01 F and best-case controller stability within 0.01 °C or 0.02 °F. The controller tuning structure allows designation of a variety of control features: manual, proportional, proportional-integral, proportional-derivative, or proportional-integral-derivative control. Differential temperature control is also available when two input sensing thermistors are used.
Accepts a wide variety of thermistors. The controller comes with a standard 15k ohm thermistor which provides a control temperature range of -20 C to 100 °C. However, the controller can be used with a wide variety of other NTC type thermistors which are pre-programmed and selected via a menu in the software. For example, a 5k ohm thermistor can also be used to extend the control temperature down to -40 °C. Also, since many laser diode packages come standard with a 10k thermistor, there are two different 10k thermistor settings available.
Remote control capability. Once the controller is programmed, it can run independent of a computer, and the set point can be adjusted in several ways. The optional MP-2986 Display and Keypad accessory can be used to adjust the set point and provide a digital readout of the set point and the sense temperature. The controller can also use a potentiometer, a 0 to 5 VDC signal, or a 0 to 20 mA current loop.
Configurable alarm actions. Several alarm types may be selected: no alarm, tracking alarm, and fixed value alarm. The alarm can be configured to either maintain the output power during an alarm or to shut down the power output. The alarm latch can be selected to either automatically restart power if the alarm clears itself or to keep the power output off until the latch is manually cleared. The controller can also provide a 25 mA signal for powering an LED or other device when an alarm occurs.
Over-current protection. In addition to alarm protection, the controller can provide over-current protection to the TE device. The setting can be adjusted in 2.5 A increments. The maximum current the controller can handle is 25 A at steady state.

APPLICATION
The TC-720 OEM, like the TC-720 is a bipolar, heat and cool, thermoelectric temperature controller capable of controlling up to 36 volts and 20 amps. One standard thermistor, model MP-3193, is included. A second sensor can be attached for monitoring and alarm purposes. The controller is housed in a die-cast aluminum box and incorporates a keypad and a liquid-crystal display. The display allows the user to monitor the sensor temperature, power output level, and menu settings. The integrated keypad accesses an easy-to-use menu system, allowing the user to adjust all of the basic controller parameters such as the set temperature, tuning parameters, and alarm parameters. The controller can also be connected to a computer via USB for more advanced program control as well as data graphing and data logging, using the supplied software.

All of the controller parameters, including some of the advanced parameters not adjustable through the on-board menu, can be adjusted using this software. The command set for the controller is also provided to allow the creation of custom software applications.

The TC-720 OEM controller regulates the output power to the TE device using pulse-width modulation (PWM). By choosing the appropriate external power supply(s), the controller can control loads from 0 to ≤36 VDC via pulse-width modulation with the on-board power transistors. (When controlling voltages of less than 12 volts, a small, 12V, 150 mA power supply must be used to power the controller’s microprocessor.)

Two alarm outputs, each capable of controlling up to 2 A each, can be used to control other loads such as pumps, fans and resistive heaters, further enhancing the controller’s capabilities. In addition, the Alarm 1 output can be reconfigured for fan speed control. Used with an appropriate fan, the controller can increase or decrease the fan speed only as needed to help minimize fan noise.

The controller has a built-in Ramp/Soak Program which provides up to 8 individual steps, and each step can be repeated as many times as needed. The program allows for looping of a sequence of steps as well.

The Proportional + Deadband control mode allows the controller to shut off output power within a given temperature range. It can gradually increase power for cooling or heating as the temperature goes outside that range. This provides for economically operation of the cooler by minimizing the power consumed by the cooler when cooling or heating is not required.

If a true linear-output control system is desired, the TC-720 OEM can be used as the control head for controlling high-power, linear-output supplies. Some of these linear output supplies are available as basic switching power supplies, allowing the user to create a relatively low cost linear control system which generates much less waste heat when compared to a typical linear system. The linear output eliminates the PWM switching and is useful for Photo Multiplier Tube (PMT) coolers and other applications that are highly sensitive to electronic noise.

APPLICATION
The TC-720 is a bipolar, heat and cool, thermoelectric temperature controller capable of controlling up to 36 volts and 20 amps. One standard thermistor, model MP-3193, is included. A second sensor can be attached for monitoring and alarm purposes. The controller is housed in a die-cast aluminum box and incorporates a keypad and a liquid-crystal display. The display allows the user to monitor the sensor temperature, power output level, and menu settings. The integrated keypad accesses an easy-to-use menu system, allowing the user to adjust all of the basic controller parameters such as the set temperature, tuning parameters, and alarm parameters. The controller can also be connected to a computer via USB for more advanced program control as well as data graphing and data logging, using the supplied software.

All of the controller parameters, including some of the advanced parameters not adjustable through the onboard menu, can be adjusted using this software. The command set for the controller is also provided to allow the creation of custom software applications. The controller is shipped as the basic control circuit mounted on an aluminum panel. One standard thermistor (model MP-3193) and a software CD are included. The software is shipped as a stand-alone program, but the LabVIEW source code for that program (version 2018 and higher) is also available upon request. A sample read and write command programmed in Python (2.7) is also available for download from the SOFTWARE tab on this web page.

The TC-720 controller regulates the output power to the TE device (or DC heater) using pulse-width modulation (PWM). By choosing the appropriate external power supply(s), the controller can control loads from 0 to ≤36 VDC via pulse-width modulation with the on-board power transistors. (When controlling voltages of less than 12 volts, a small, 12V, 150 mA power supply must be used to power the controller’s microprocessor.)

The controller has a built-in Ramp/Soak Program. It provides up to 8 individual ramp + soak steps, and each step can be repeated as many times as needed. The program allows for looping of a sequence of steps as well.

If a true linear-output control system is desired, the TC-720 can be used as the control head for controlling high-power, linear-output supplies. Some of these linear output supplies are available as basic switching power supplies, allowing the user to create a relatively low cost linear control system which generates much less waste heat when compared to a typical linear system. The linear output eliminates the PWM switching and is useful for Photo Multiplier Tube (PMT) coolers and other applications that are highly sensitive to electronic noise.

The TC-720 OEM is also available. This is a basic version of the controller for Original Equipment Manufacturers (OEM’s) as a component in a system where the display, keypad, and box cover are not needed. The controller is shipped only as the basic control circuit PCB mounted on an aluminum panel.

This sensor is the only temperature sensor that TE Technology sells which is moisture resistant as shipped. While not rated for immersion in water it is recommended for cold plates, liquid coolers, and other applications where surface condensation may occur on the sensor head.

This sensor has a rugged 6.35 mm square, 25.4 mm long square aluminum head (0.25 x 1.0 inches). A 3.6 mm (0.142”) through hole is drilled near the end for attaching the sensor via a screw. The large contact surface allows for good thermal contact to the device being measured, so it is ideal for measuring the temperatures of cold plates and liquid exchanger plates.

The MP-3193 may also be used to measure air temperatures whenever a rugged sensor is desirable. The larger thermal mass may not offer the fastest time response when sensing air temperatures, but for large, slow reacting enclosures the time response of the sensor can still be much faster than that of the entire system.

The main features of this sensor include:

Moisture resistant
Large thermal contact area makes it easier to obtain repeatable, accurate temperature measurements
Long 900 mm 26 AWG wires eliminate the need for adding extension wires in most cases

The resistance is 15K ohms at @ 25 °C (TS-67/ 15K curve). Operating temperature range is from -20 °C to + 100 °C, and the tolerance is +/- 1.0 °C within the 0-70 °C measurement range.

This thermistor can be used on all of TE Technology’s temperature controllers. However, the wire ends are not terminated so “fast-on” spade connectors must be added for use with the TC-24-10.

A standard lug-mounted thermistor, 15K ohms at @ 25 °C (TS-67/ 15K-1 curve). Wire is 24 gauge stranded, overall length is 527 mm. This sensor this is essentially a 4.8 mm diameter aluminum tube that has been flattened at one end with a mounting hole placed in the flattened section. The wires are not terminated (for use with screw-type terminal blocks).
