Waters SHC Column Heater/Cooler

The Waters SHC (Melcor 385150-01) column heater/cooler is designed to manage and maintain column temperature within the column compartment. The heater/cooler controls the sample compartment temperature from 4 to 40°C using Peltier-based heating and cooling technology. This compact module is standard on some Alliance HPLC systems and is easily inserted into the carousel housing area. The column heater/cooler is a combination forced-air convection heater and cooler. When the temperature is set at the separations module, a command is sent to a column heater/cooler CPU board that controls the temperature by applying power to the thermoelectric devices to achieve the desired column temperature. The column heater/cooler contains many of the same components as the column heater with the exception of a thermoelectric engine for heating and cooling, and the additional fan for exhausting power supply heat. In addition, the column heater/cooler has an internal onboard power supply. The power supply is necessary for additional power required to operate the thermoelectric heater/cooler engine circuit.
