Temperature Pressure Controls

Pressure controls serve various functions, which may be divided into control and protection functions.  Examples of control functions are compressor cycling, pump-down or defrost control.   Protection functions include pressure limiting and cut out against excessive pressures, against loss of charge or for freeze protection.

The PS1 and PS2 Series are respectively single and dual pressure control designed for use on high and low pressure applications in refrigeration and heat pump systems.

The FD-113-ZUK is an oil pressure safety control used in commercial refrigeration and air-conditioning applications.  It senses the effective oil pressure on pressure lubricate compressors and energizes a time delay if needed.
