The new multi-compressors chiller line doesn’t need any water tank thanks to the electronic modulation from 6 to 10 steps. The management software manages the compressors working cycle according to the load requirements and let them start alternatively to guarantee an equal number of working hours. Scroll compressors with oil sight glass. They are furnished with an internal overheat protection and crankcase heater. Axial fans are directly coupled to a three-phase electric motor with external rotor. A safety fan guard is fitted on the air flow discharge. Condenser made up of a finned battery with copper pipes and aluminum fins. Evaporator AISI 316 stainless steel braze welded plate type with two independent circuits on refrigerant side and water side. Adaptive floating, technology optimizes the water set point and modulates the pump and the fans, avoiding the use of the inertial tank because the units can work even with low content of water in the system. The hydraulic circuit SD version includes: Evaporator, work probe, antifreeze probe, differential water pressure gauge, manual air breather valves, inverter circulation pump, expansion chamber, safety valve, system load and discharge pressure gauges and faucets.
