Manual Brochure

The Thermo Neslab RTE-221 Refrigerated Bath / Circulator, -23°C to +100°C refrigeration system skips the intermediate HCFCs that many other brands will use, and provides the ultimate solution to the ozone problem: an absolutely Freon® Free refrigeration system.

This refrigeration system is continuously operational below 50°C and is balanced by a cycling heater. Above 50°C, the compressor may be shut off to take advantage of ambient conditions for temperature control. This translates to energy savings and rapid heat up for you.
