Circulating Baths are supplied with heating only or with heating and cooling capabilities to serve many lab applications. They offer the versatility of bath work areas plus ability to also circulate via external lines to heat or cool other lab apparatus. Chiller function is for external cooling circulation only and operates in a narrower temperature range with less precise temperature stability. Chillers often replace wasteful tap water condensers and rotary evaporators. All units with refrigeration systems are CFC-free.

All units have bright LED digital displays. Baths have proportional control to ±0.01°C stability. Setpoints and bath temperatures are displayed to 0.1°C. Chillers have digital setpoint resolution to 1°C and maintain ±0.1°C stability.

Bath models with heating only have tap water cooling coils to provide capability for rough cool down near ambient temperatures, but models with refrigeration capability are recommended for controlled cooling or to lower temperatures to -25°C (-13°F). All wetted parts are stainless steel, and bath models have high temperature and low liquid safety cutoff.

Chillers have a sealable fluid reservoir to allow circulation to an open tank. Their hermetically sealed compressor and hot gas bypass system of temperature control eliminates on/off cycling and premature wear in continuous-duty circulation.
