Features

Thermoelectric Cooler (TEC) Elements are Compatible with TED4015 Temperature Controller, OEM Temperature Controllers, or Rack Mountable Temperature Controllers
All Heaters, Thermistors, and Temperature Transducers are Compatible with the TC200 Temperature Controller

Thorlabs offers a wide range of thermal management accessories, including thermoelectric coolers, resistive heaters, thermistors, and temperature transducers. Thermoelectric coolers can both cool and heat, allowing for quick response to thermal drift or shock. These devices are ideal for total and precise temperature regulation. For applications that require only heating or steady-state regulation slightly above room temperature, resistive heaters are a reliable and easily regulated heat source. Regardless of application, temperature monitoring is essential for any temperature regulation system. Thorlabs' thermistors and thermocouples provide precise and accurate temperature measurements.

Thermoelectric Coolers
We offer a line of single-stage thermoelectric coolers, which can maintain temperature differentials of at least 73 °C for a 50 °C hot surface. Our dual-stage TEC (item # TECD2) provides a larger temperature differential between the hot and cold surfaces of the device; when the hot surface is 50 °C, it is capable of maintaining a differential of 108 °C in vacuum. The hot and cold surfaces of the dual-stage TEC are metalized copper for soldering in order to ease integration into the system.

All of our TECs work well with our TED4015 225 W Benchtop Laser Diode Temperature Controller and our rack-mountable temperature controllers, which are designed for the PRO800 Chassis. These TECs can also be driven by our OEM Temperature Controllers in SMT or THT Packages. When using a TEC for thermal regulation, care should be taken to electrically isolate the sides and leads of the TEC.

Resistive Heaters
Thorlabs offers four types of resistive heaters: foil, cartridge, metal ceramic, and metal ceramic with thermistor. The HT10K and TLK-H are resistive foil heaters with a pressure-sensitive adhesive backing and a 10 kΩ NTC thermistor integrated directly onto the heater. The HT15W is a miniature 15 W cartridge heater, which can be used for many applications requiring small areas to be heated. Our metal ceramic heaters come in either round (HT19R) or square (HT24S and HT24S2) geometries and provide fast thermal response. The HT10KR is a metal ceramic heater with a 10 kΩ thermistor and can reach a maximum temperature of 75 °C. These small but high powered heaters are ideal for thermal regulation of optical components. All of the heaters sold here are compatible with Thorlabs' TC200 temperature controller.

Thermistors and Temperature Transducers
We also offer three models of thermistors and temperature transducers. The TH10K is a 10 kΩ thermistor with 1 °C accuracy that is meant to be used in common TEC applications. The TH100PT is a 100 Ω platinum Resistance Temperature Detector (RTD) with a positive linear temperature response. These thermistors are compatible with the TC200 temperature controller; the TH10K can also be used with the MTD415T TEC controller in an SMT package. Finally, the AD590 is an integrated circuit (IC) temperature transducer with an output current that is proportional to absolute temperature. All our thermistors and AD590 temperature transducers are compatible with the TED200C 12 W Benchtop Laser Diode Temperature Controller and our rack-mountable temperature controllers. For high temperature applications, constantan or manganese wires may be used.

Is this heater vacuum compatible, down to 10^-6 mBar?

nbayconich (posted 2019-11-15 09:36:15.0)

Thank you for contacting Thorlabs. We have not yet thoroughly tested these heating elements in vacuum conditions. Our Tech support team will reach out to you directly with more information.

Would it be possible to attach this to a curved surface? I need to find a way to cool a Ti:Sapphire crystal that may be housed in a round metal tube. There is some latitude in the diameter of the crystal and its housing, as these will both be custom parts.

YLohia (posted 2019-11-05 08:45:12.0)

Thank you for contacting Thorlabs. The TECD2S should be mounted to a flat surface with flatness rated better than +/-0.025 mm over the entire TEC mounting area. The surface should also be clean and free of dirt, oil, scratches, and burrs. We will reach out to you directly to discuss the possibility of mounting to your particular tube.

Hello, can the HT10K be connected to an ITC 8052 if ordered without the TLK connector?

asundararaj (posted 2019-09-27 03:24:01.0)

Thank you for contacting Thorlabs. The HT10K can be wired with the ITC8052 for heater control, but this is not the recommended process because the temperature control loop could be very unstable. The problem is that a TEC element will heat or cool depending on the polarity of the applied current, while the HT10K will heat for both polarities. The control loop in the ITC has been designed for TEC elements, i.e. it assumes that one polarity will increase the temperature and the other one will decrease it and the current changes are made accordingly. With the HT10K this is however not true and this can result in an unstable operation.

Buenas noches Uso una peltier tech 3s. Me gustaría saber el COP con el que trabaja este tipo de celdas peltier Me comunico del Instituto Tecnologico deTuxtla Gutiérrez Saluds

nbayconich (posted 2019-04-01 09:39:26.0)

Thank you for contacting Thorlabs. The COP or work efficiency is dependent on the amount of temperature change ΔT required and applied current I of the TEC element. There isn't an exact % efficiency per TEC element as the efficiency will decrease as ΔT increases. I will contact you directly with more information regarding the change in temperature, cooling capacity and the COP of these TEC elements.

What the maximum temperature of hot side (TH) of the Single-Stage TEC Elements is allowed?

nbayconich (posted 2019-03-28 10:30:57.0)

Thank you for contacting Thorlabs. We unfortunately do not have a maximum temperature limit of the hot plate itself for these TEC elements. The temperature of the hot plate will be typically limited by the mass of the sample being cooled, ambient temperature of the environment, etc. I would refer to the values of the max allowed temperature difference, heat load, current and voltage to make sure not to exceed either of these specifications. I will reach out to you directly to discuss your application and needs.

abushagur (posted 2019-01-11 16:27:29.19)

I am interested buying the TEC and AD590 sensor, In our facilities we have ITC510 temperature controller, so can I used only for TEC control and not for Laser Diode? second, Do you supply also the circuit board for TEC and sensor connections? so that I just plug and play once I have my sensor mounted on the heat sink>>> My application only to have temperature controllable station..... Thanks for your support

nbayconich (posted 2019-01-18 05:30:11.0)

Thank you for contacting Thorlabs. Yes you can use the ITC501 as a temperature controller only and do not need to use the LD current driver outputs. Several TEC elements we supply can be used with the ITC501 controller as long as the applied voltage to the TEC element you choose does not exceed the ITC501’s compliance voltage and you do not exceed the TEC element’s max heat load, max applied voltage or max temperature specifications. We do not currently provide circuit boards for these devices at the moment.

Should I try to widen the hole of HT19R by a few mms? Will this destroy the heater?

nbayconich (posted 2017-12-29 08:18:51.0)

Thank you for contacting Thorlabs. Drilling a larger through hole is not recommended, and we can't guarantee the specs after drilling. A larger hole might damage the ceramic heater. I will reach out to you directly with more information.

Are your TECs capable of both heating up and cooling down?

nbayconich (posted 2017-07-11 10:35:54.0)

Thank you for contacting Thorlabs. Our TEC's are capable of both heating and cooling. The primary purpose of these TEC's is to cool but can be used to heat a device if the hot surface is in contact. For general heating purposes we recommend using our resistive heaters, thermistors and temperature transducers. I will reach out to you directly.

I don't see a maximum temperature spec on HT10K or TLK-H. Can you provide this information?

myanakas (posted 2014-05-20 09:06:31.0)

Response from Mike at Thorlabs: Thank you for your feedback. The temperature range for the HT10K and TLK-H is -32 to 100 °C (-26 to 212 °F). Based on your feedback this specification has been added to the web presentation for these parts.

user (posted 2014-01-27 04:25:16.06)

What is the maximum operational temperature for the HT19R heater element? The heater element HT19R ships with a note saying the maximum is 180 C, while the data sheet online says 400 C.

sharrell (posted 2014-01-27 09:43:26.0)

Response from Sean at Thorlabs: Thank you for your pointing out this inconsistency. 400 °C is the correct maximum temperature specification. It appears that the item shipped with an older, incorrect version of the spec sheet; we are working with the production team to get the items in inventory corrected now.

Would be great if Thorlabs also sold connecting cable (connector one end and alligator or other quick clips on other end) to go between Thermistor, heating elements and one of the standard temperature controllers.

Single-Stage TEC Elements

General TEC Diagram
*E is only featured with TEC1.4-6

Performance specifications are given in the table below as a function of T_H, the temperature of the hot surface of the TEC. I_max is the maximum allowed current across the TEC element and V_max is the maximum allowed voltage difference. These values should not be exceeded. Q_max is the maximum heat load that the TEC can handle; ΔT_max is the maximum temperature difference between the hot and cold surfaces of the TEC in a dry nitrogen environment.

When choosing a TEC, it is important to know the heat load, or cooling capacity, of the system (how much heat must be transferred away from the device) and to match that load with a capable TEC. The TEC should be rated for a maximum heat load above that which is emitted by the system, and a sufficiently large heat sink must be attached to the hot surface. Proper thermal contact is necessary for optimal heat transfer. Ensuring that the TEC is of the proper size for the system is important as well as using thermal tape or grease to help facilitate heat transfer. It is important to note that the heat transfer efficiency is affected by the ambient environment; care must be taken to avoid condensation on the cold side. Large changes in background temperature or significant humidity can hamper heat flow. These factors should be taken into account when choosing an appropriate TEC.

All the TECs available here, with the exception of the TEC3-2.5, TEC3-6, and TEC1.4-6, are silicone sealed to protect the core from moisture and condensation.

We offer several kinds of temperature controllers for our TECs. The TED4015 225 W TEC Controller is a benchtop laser diode temperature controller with excellent temperature stability. Our rack-mountable temperature controllers are also capable of excellent temperature stabilization and additionally are compatible with the PRO800 Chassis. For OEM, custom, or embedded systems, we offer OEM Temperature Controllers in SMT or THT Packages as well as on a PCB with mounting standoffs.

Our Dual-Stage Thermoelectric Cooler (TEC) is ideal for situations where additional cooling is required. The TECD2 provides a temperature difference between the hot and cold surfaces of up to 108 °C when the hot surface is at 50 °C. The hot and cold surfaces are metalized copper to allow for soldering. This TEC is designed to operate in vacuum levels of 10^-6 Torr with proper cleaning and bake out.

The performance values for our Dual-Stage TEC is given as a function of T_H, the temperature of the hot surface of the TEC. I_max is the maximum allowed current across the TEC element and V_max is the maximum allowed voltage difference. These values should not be exceeded. Q_max is the maximum heat load that the TEC can handle; ΔT_max is the maximum temperature difference between the hot and cold surfaces of the TEC in vacuum.
