In this two-minute tutorial, we're going to look at a couple of options for cooling your Agilent turbomolecular pump to ensure optimal performance and reliability. Turbomolecular pumps generate heat as a result of compressing gases, particularly in the high compression molecular drag stages. Heat is also generated by the operation of the electrical motor and through the spinning rotor’s high speed support bearings. Appropriately cooling the pump to remove that heat can have a profound impact on the longevity and reliability of the pump. Most applications require only the use of an air cooling kit consisting of a fan, a mounting bracket, and a cable to power the fan from the rack mount or on-board turbo controller. Attach the fan to the turbo pump body according to the instructions provided. Then simply connect the cable to the turbo pump controller to start cooling the pump. For higher flow applications which generate more heat, or for operation in higher ambient temperature environments, a water cooling kit is a better option. You can connect your cooling circuit to the turbo pump’s water cooling channels through the dedicated connection accessories. Be sure to follow all cautions in each pump’s user manual regarding water temperature, flow rate and contaminants.
