Flex drive capacity control

New Flex drive capacity control is a next-generation capacity control system and allows compressors to save energy.The Flex drive Plus is the perfect combination of modern and traditional capacity control that can handle a cooling power duty of 78.1 kW to a range of 1061.95 against an input power of 58.4 to 252.75.

In comparison to the conventional fixed drive compressor units found in the market today the Flex drive plus exhibits a higher capacity with a cooling power range of 171 kW to 857 kW against an input power of 111 kW to 204 kW. In reality, less compressor units are needed to supply the same duty, drastically reducing operating costs and expenses.

By using the Flex drive application, the amount of refrigerant varies and requires a special design based on features that can handle the variations. Not only a HR E-motor and a frequency drive, but the units need to be equipped with systems to control the variations and avoid oil to carry over. The flex drive units offer a reliable backup system and if less compressor units are needed, the system can be suited to fit a customer’s needs. Some examples of current backup systems are the double- shaft seal application and the magnetic- drive oil pumps.
