Johnson Controls Dual Pressure Control, LR 20-100 psig, HS 100-500 psig

P70 single and dual function pressure controls are used in commercial air conditioning and refrigeration applications. The load-carrying contacts provide direct control of A.C. motors within the control?s rating. (See cover label for the electrical rating.) The controls can be used with R- 12, R-22, R-500, or R-502 refrigerants. Specific models for ammonia applications are also available. The MICRO-SET construction of low pressure controls and low side of dual models permits differentials to a minimum of 5 psi (34 kPa). Specifications: High Pressure Diff.
