Description
P21 Series Air Conditioning Limit Control - dual pressure limit control with low pressure and high pressure controls mounted on a common bracket.
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.
In the Series P21, a low pressure and a high pressure control are mounted on a common bracket to provide dual pressure limiting from a single assembly. Series P20 and P21 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.
Both high and low pressure controls are factory adjusted to equipment manufacturers' specifications for use on non-corrosive refrigerants and are not adjustable in the field. This provides a high pressure limit stop that meets UL requirements at no extra cost.
Features
* Accurate repeat performance and long life; test strength far above the most severe operating and standby conditions
* Compact - less than the size of a cigarette pack
* Transmission of diaphragm movement is by a stainless steel power lever operating on a stainless steel pivot - load aligned to reduce friction
* Trip-free manual reset - contacts cannot be blocked closed; reset tab must be released before restart
* Controls for use on non-corrosive refrigerants
* Enclosed dust-tight Pennswitches
* A dust gasket prevents sand, dirt and dust from lodging in the diaphragm and diaphragm push-pin area
Applications
* Package residential and commercial air conditioning units
* Dual (high and low) pressure limiting on non-corrosive refrigerant systems
* Refrigeration applications where a fixed range setting is acceptable
SETPOINT AND RANGE NOT OEM-DOCUMENTED.
