Head Pressure Control and Condenser Fan Speed Controller
Each refrigerant circuit (TEV or EEV) is fitted with condenser pressure transducers and a modulating condenser fan
speed controller to allow the designed head pressure to be monitored and maintained under varying ambient conditions.
Condenser fan speed control settings are input via the display keypad.
Evaporator Fan Speed Controller
(Sizes 6 - 26) Evaporator fan speed control is easily set via the display keypad and can be incrementally increased
or decreased to meet on site airflow and external static pressure requirements.
Filter Change Alarm
Filter change is managed by the AireTronix software, and is based on fan(s) hours run with an alarm being generated
when the pre-set run time limit has been exceeded. The set-point value can be adjusted to suit each application and is
factory set to 2000 hours.
Hours run log or visual service indicator provided.
LPHW Frost Protection
(DX units with LPHW option)
The coil temperature sensor is mounted on the DX coil and has a fixed 3°C low limit setting to disable DX cooling.
