Recirculating Chiller without gases PSL Rheotek is proud to introduce NEVA, a new compact thermoelectric re-circulating chiller. NEVA has been developed using the latest solid-state components in conjunction with advanced thermo-dynamic modelling and embedded electronics. NEVA is the ideal solution for precision cooling a wide range of applications including constant temperature baths, semi-conductors, lasers and other apparatus requiring background cooling. Models available NEVA 150 – stand-alone re-circulating chiller module with external bench top power supply. Nominal cooling capacity 150W at 20ºC NEVA 300 – stand-alone re-circulating chiller module with internal power supply. Nominal cooling capacity 300W at 20ºC.
