TCP50™ Cold-Plate

ElectraCOOL™ TCP50™ Thermoelectric Cold-Plate

Our popular TCP50™ Cold-Plate has a four inch (100mm) square surface and takes less than 10 minutes to reach the freezing point, in a 70 °F ambient.

It's a compact, easy to use, reliable and affordable. With no refrigerants or gases, it's environmentally friendly.

TCP50™ may be used for either cooling or warming. In an ambient temperature of 68 ºF (20 ºC), and no active load, the surface temperature will drop to about 5 degrees below freezing. Alternatively, the surface can safely be heated to 175 ºF (75 ºC).

For applications that require temperature control, the TCP50™ can be connected to a temperature controller, like the Z31.

TCP50™ is used in a wide variety of laboratory, calibration, test - quality control, electro-optic/laser and research applications. Typical medical/biomedical applications include sample cooling or temperature stabilization, tissue preparation, histology, cold & hot dry wells and pain/nerve research.

With a 100mm square surface, the TCP 50 will accommodate Petri dishes up to 100mm but 80mm seems ideal for temperature uniformity.

While typically used on a laboratory or work table the TCP50™ may be mounted in any orientation. Many customers have used multiple units to "sandwich" (or surround) an item requiring cooling from two or more sides such as a liquid heatsink or cylinder.

The cold-plate can be customized or fabricated for customer specific applications such as mounting sensors or optics packages. The plate is 6063 aluminum with a black anodized finish. Contact us for a machining quotation if you need ten or more TCP50s.
