Jun 21, 2016 · There are multiple causes of a fluid chiller barrel (evaporator) freezing: Fluid composition: in a system utilizing brine or glycol, concentration being too low. Often chillers for certain processes chill to temperatures lower than comfort cooling.

Cooling baths - Chemistry LibreTexts

Cooling baths are used extensively in organic chemistry for a variety of reasons. The low temperature of these baths is determined both by the appropriate use of solvent as well as a cryogenic agent such as liquid nitrogen, dry ice (CO 2) or ice. Most of these methods require continuous monitoring to ensure the temperature .

Cooling bath - Wikipedia

A cooling bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C.These low temperatures are used to collect liquids after distillation, to remove solvents using a rotary evaporator, or to perform a chemical reaction below room temperature (see Kinetic control).

Water-Cooled Condenser - an overview | ScienceDirect Topics

In water-cooled condensers, the refrigerant should condense at 5–10 K above the water inlet temperature, a low value results in a not only higher COP but also higher initial costs. With open-type cooling towers, the water should cool to within 3–6 K of the air wet-bulb temperature, and with closed cooling towers, the water should be cooled .
