Mar 10, 2020 · The air-cooled chiller utilizes the shell and tube evaporator to exchange heat between water and refrigerant. After the refrigerant system absorbs the heat of water and the water is cooled to cold water, the heat is brought to the finned condenser by the compressor, and then dissipated to the air outside by the cooling fan.
Apr 04, 2019 · A chiller is an important part of many rotovap setups as it’s responsible for cooling the coolant that flows through the condenser. It’s possible to avoid purchasing a chiller, for example by using a dry ice condenser or juryrigging your own chiller , but in most cases, a suitable chiller will be needed.
May 09, 2018 · If a chiller cannot reach its setpoint temperature, it will give a high temperature warning and stop chilling. In the case of using a chiller with a rotary evaporator system, it’s important to have your chiller doing its job of chilling the coolant for the condenser. In this post, we take a look at several possible reasons your chiller isn’t holding temperature and what you can …
Jan 05, 2018 · The rotovap chiller is a low temperature liquid refrigerant equipment which takes mechanical forms to refrigerate.

Oct 20, 2016 · So, in order to condense 20L/hr I need a chiller with 3.67 kW of cooling power at a temperature of around 20C less than the boiling point of ethanol at the pressure in the rotovap. So if I want to be able to distill down to 75 Torr I need 3.67 kW at around 0C. The specs on the chiller from AI say it has 2.8 kW at 0C which clearly doesn't cut it.
