The P100 series are encapsulated, non-adjustable, direct mount pressure controls typically used for low and 
high-pressure cut-outs for OEM applications. The P100 series are produced according to switchpoint requirements of customers. The small dimensions, weight and protection class makes the P100 series applicable for use without the need of additional mounting brackets. The P100 series can be used for all non-corrosive refrigerants like R134a; R32; R404, R410A, R290 (Propane), R600, R1234, R744 (CO2) and many others.WILL BE REPLACED BYP100AP-3C150-225# OPENS ON FALL,

            ![System 450 is a family of modular, digital electronic controls that is easily assembled and set up to provide reliable temperature, pressure, and humidity control for a wide variety of Heating, Ventilating, Air Conditioning and Refrigeration (HVACR) and commercial/industrial process applications. The System 450 control system is designed to replace System 350 control system and System 27, and provide many additional features and benefits with less than a dozen model variations. All System 450 control modules are multipurpose and field configurable out-of-the-box; each module is designed for use in temperature, pressure, and humidity systems. A System 450 control system can be easily assembled and configured to monitor and control temperature, pressure, and humidity simultaneously. A single C450 control module can be set up as a stand-alone control or connected to expansion modules to control up to ten outputs based on any of the three available inputs. A control system may consist of relay outputs (Single-Pole, Double-Throw [SPDT]), analog outputs (010 VDC or 420 mA), or any combination of relay and analog outputs.RESET CNTRL MOD W/LCD 4 BUTTON TOUCHPAD UIandSPDT RELAY OUTPUTPROVIDES 2 SPDT OUTPUT RELAY System 450 is a family of modular, digital electronic controls that is easily assembled and set up to provide reliable temperature, pressure, and humidity control for a wide variety of Heating, Ventilating, Air Conditioning and Refrigeration (HVACR) and commercial/industrial process applications.
