Technical Features T op Class High COP In the new model sereis, the power consumption is largely reduced over the current model series due to newly designed high-efficiency cooling system. Also COP is largely increased from. in the current 100HP model to 5.1 in the new 100HP model. COP Comparison Current Model New Model COP. Cooling Capacity (kw) 1 COP 5.1 Cooling Capacity (kw) COP 10% UP!! High-performance A-type Screw ~Newly Designed~ NEW Discharged Gas Cyclone Oil Separator Suctioned Refrigerant Gas Screw Rotor Oil Differential Pressure Lubrication Mechanism Oil Reservoir Image of Large Capacity Operation Image Built-in Cyclone Oil Separator Low oil carrying-out is realized and reduction of heat transfer efficiency is minimized. No outside pump is required due to the reliable differential-pressure oil-feeding system. This oil-feeding system, which does not use any electrical mechanism, prevents the compressor from being damaged and maintains long-term stable operation. High Technology by Internal Manufacture Because all manufacturing processes, from rotor manufacturing to unit assembly, are done internally, exceptional reliability is achieved. Low Vibration, Low Noise Without the conventional demister chamber system, no noise is produced during oil separation of discharge gas. A vibration-proof base is not required for the chiller body thanks to the firmly-secured, low-vibration screw compressor. Highly Reliable Shell and Tube Heat Exchanger ~Newly Designed~ Simple structure and easy for maintenance Reduced cost and adapted to satisfy various demands Freeze protection thermostat and other safety devices Integral and reliable performance

P recise Capacity Control Technology The temperature of the chilled water outlet can be kept at the set temperature ±1 C by continuous capacity control, so it is suitable for industrial use. 8 6 Start water temperature sec.
