HEAD PRESSURE CONTROLS

Control head pressure from liquid line or discharge air temperature

Air conditioning systems lose efficiency when the outdoor air is cool but indoor conditions call for cooling.  The LA model FanHandler regulates the condenser fan speed to keep the system operating efficiently in all weather conditions.  Because the outdoor fan is quieted, the LA model might be called the "Good Neighbor" control.

• Maintains head pressure during all weather conditions, allowing air conditioner to operate effectively regardless of weather.

• Operates smoothly.  No more "hunting" like other head pressure attempts.  So steady you'll think your gauges are broken!

• Quiets the outdoor fan during most weather conditions.

• Originally designed for computer-room air conditioners.

• No special motor requirements (see "A Word About Motors" here)
