“PDC“ System® (Power Demand Control)

1 controller can operate up to 8 ACU‘s over CAN Bussystem. This can provide up to 64kW (220.000 BTU/h) of cooling, and 40kW (136.500BTU/h) of heating capacity The cooling/heating power is controlled automatically depending on actual power requirements. ln case of failure of any unit the system starts automatically other unit(s). Up to 7x redundancy and very
high reliability
     Take only that power, that you need and have reserves

CAN BUS System
Quick install: only 1 power and 1 control cable
CAN bus controlled over fiber optics (only MIL-461 E models)
Failsafe programs: redundancy, high reliability

INVERTER powered compressors:
No high start up currents. This prevents generators against overloads
Stepless power regulated compressors
Exactly regulation of room temperatures with no hot I cold effects
     Guarantees a perfect room temperature

Automatically and stepless regulated motor fresh air flap
2nd evaporator ventilator for lower noise operation
Air cleaner system PHI® (Photohydroionization) -  Frees the air from bad smells and kills bacteria
