TECHNICAL FEATURES

• Compressors. Scroll with oil sight glass. They are furnished with an internal overheat protection and crankcase heater, installed on rubber shock absorbers.
• Fans. Axial fans 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 aluminium fins.
• Evaporator AISI 316 stainless steel braze welded plate type: With one circuit on the refrigerant side and one on the water side in models 0247÷03124.
• Managing system and microprocessor regulation.
• The hydraulic circuit includes: Evaporator, work probe, antifreeze probe, differential water pressure gauge and manual air breather valve.
• Adaptive floating, technology optimises 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.
