Description
P20 Series Air Conditioning Limit Control - field replacement pressure cutout control with screwdriver-adjustable setpoint and trip-free manual reset.
These air conditioning limit controls are specially designed for package residential or commercial air conditioning units. They are for use with all non-corrosive refrigerants within pressure range of controls - water or air cooled. They may also be used for refrigeration applications where a fixed range setting is acceptable. Models are provided for low side pressure, high pressure or dual pressure and may be supplied with automatic recycle or manual reset.
The P20 Series are field replacement high and low pressure controls for non-corrosive refrigerants. They include a dust-tight contact unit with quick connect connectors, and a 36 in. or 42 in. capillary with 1/4 in. sweat section. The setpoint is screwdriver adjustable.
Series P20 controls feature many desirable advantages not found in any other controls. Exclusive, service proved pressure element (about the size of a quarter) provides accurate repeat performance - with substantial safety factor for long life under extreme operating and equalized standby pressures. Controls are compact and ideal for panel mounting and all applications where space is at a premium.
