Thermoelectric Coolers & Peltier Devices
Precise, solid-state cooling with no moving parts.
cTech supplies a wide range of high-quality, competitively priced thermoelectric coolers (TECs) and Peltier devices from world-leading manufacturer Ferrotec — from single-stage modules for general cooling and temperature cycling, such as life sciences, to multi-stage designs for deep temperature differentials.
The product range
A closer look at the materials we supply.
Specifically designed for temperature cycling applications such as life sciences. Significantly longer thermal cycling operational life.
Suitable for a wide range of cooling and heating applications with low to high heat pumping capacities.
Provide significantly higher temperature differentials than are obtainable with standard single-stage modules.
Suitable for compact cooling and heating applications, including laser diode cooling, infrared systems, electro-optics, and other low-power uses. 20 Series modules are tested to Telcordia GR.
Designed to maximize heat pumping capacity. By increasing cooling capacities and efficiencies in a standard thermoelectric cooler footprint.
Ferrotec offers standard modules with custom modifications, such as wire leads or sealing, as well as fully custom modules designed for specific size, shape, performance, materials, or metallisation requirements.
For applications requiring round centre hole and multi hole designs.
Silicone – Effective moisture barrier. Polymer – Ultimate corrosion Resistance. Epoxy – Standard moisture protection.

Sub-ambient cooling
Cool below ambient temperature without refrigerants or compressors — ideal for sealed, sensitive systems.
Precise control
Millikelvin-level stability when paired with a PID controller — perfect for lasers, sensors and analytical instruments.
Solid-state reliability
No moving parts, no fluids and long service life — a proven choice for defence and medical hardware.
Standard & bespoke
Off-the-shelf modules or fully custom geometries and pin-outs engineered for your application.
Thermal cycling
Used in PCR DNA amplification and genomic sciences — engineered for long-life temperature cycling such as life sciences.
Heat & cool
Reverse the current to switch from cooling to controlled heating — a single device, two operating modes.
