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 adjustable pressure control designed for use on high and low pressure applications in refrigeration and heat pump systems.PS3
and PS4 Series are pressure controls with fixed switch point settings. They are manufactured especically for OEM needs.
The Differential Pressure Controls Series FD-113
is for 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.TS1
Series are mechanical thermostats with adjustable switch point and differential.
