Binary and TrinaryTM Switches R12/R134a Compatible Binary Switches perform two functions; A. Prevents compressor operation if system has refrigerant loss or ambient temp. drops too low. B. Prevents compressor operation if high side pressure rises too high. Automatically resets when pressure drops to normal. Trinary II Switches are found on systems equipped with radiator shutters and/or electric or air fan clutches. They perform three functions: A. Prevents compressor operation if system has refrigerant loss, or ambient temp. drops too low. B. Prevents compressor operation if high side pressure rises too high. Automatically resets when pressure drops to normal. C. Overrides shutter/fan control to keep head pressure within normal range.

SOLENOID VALVES AN AIR OPERATED SOLENOID VALVE is an electronic control used to operate (engage & disengage) the air actuated engine fan clutch and/or radiator shutters on the vehicle. It can be plumbed to operate in either a normally open (N.O.) or normally closed (N.C.) position, depending upon the type of fan on the vehicle, and the specific inlet port used on the solenoid. See illustrations below to determine the correct inlet port. NORMALLY OPEN NORMALLY CLOSED TYPICAL PLUMBING For use on Kysor, Bendix For use on Horton N.C.

Easy to install, economical smart protection 1596 Prevents rapid cycling under harmful high or low pressure conditions. A Detection and Protection System The ACX-10 A/C Life Extender detects pressure that s too high or low, and too much or too little voltage. Then, it protects expensive system components from being damaged, and saves you maintenance costs and downtime. Pressure Protection When the ACX-10 detects persistent high or low system pressure, it disengages the A/C clutch until the pressure returns to the normal, safe operating range. Voltage Protection The ACX-10 detects over- and under-voltage conditions, and temporarily disengages the A/C clutch until the voltage returns to the normal, safe range. Starter Motor Protection The ACX-10 unburdens the starter motor and extends its life by delaying the A/C clutch engagement until 15 seconds after ignition. 551
