ThermoRack 800 Thermoelectric Recirculating Chillers

Cooling Capacity 730 to 950 W @+20 °C; Process Fluid Flow Rate 3.5 lpm @ 30 psig; 3/8” Female NPT Fittings; Dual Centrifugal Pump; Wetted Materials: Aluminium, Stainless Steel & Polymers or Cu, Stainless Steel, Brass & Polymers

The ThermoRack 800 Thermoelectric Recirculating Chiller is a high-capacity, rack-mounted thermal control system designed for precision cooling in demanding industrial, medical, and photonics applications. Developed by Solid State Cooling Systems, this 6U air-cooled unit delivers cooling capacities from 730 to over 950 watts depending on configuration, with temperature stability of ±0.05°C even near ambient. Its solid-state thermoelectric design eliminates the need for compressors or refrigerants, ensuring quiet operation, low vibration, and long-term reliability.

With dimensions of 19 x 20 x 11 inches (48 x 51 x 27 cm) and a weight of 55 lbs (24.5 kg), the ThermoRack 800 integrates seamlessly into standard 19-inch electronics racks. It supports a standard operating range of 5°C to 50°C, extendable to -5°C with the low-temperature option. The system features a digital PID controller for precise heating and cooling, and offers USB or optional RS232 communication for remote monitoring and control. Designed for global deployment, it includes universal power input (100–240 VAC, 50/60 Hz) and meets international safety and environmental standards.
