Air Cooled Screw Chiller & Heat Pump
18 basic models with cooling capacity ranging from 196kW to 1164kW
R134a friendly refrigerant has no ozone-depletion potential
Features
Reliable Operation
3. Each unit was extensively tested before delivery to verify its operational reliability and to ensure a smooth startup.
Easy and Fast Installation
Components
2. High efficiency heat exchanger. Condenser adopts the copper tube & hydrophilic aluminium fin coil type structure, the appearance is V-shape. This design increase the heat exchange area, reduce the temp. differences, thus increase the heat exchange efficiency by 20%. Evaporator built with high efficiency shell & tube type heat exchanger, factory insulated with flexible close cell material.
3. External rotor type axial fans, equipped with three phase direct drive motors, low noise 8 poles, protection level IP54, provided with a protective outlet grille.
4. Electric panel consist of: compressor contactor, fan motor contactor, compressor isolating switch, fan protection breaker, phase sequence relay and microprocessor with function display. All of them are Schneider Electric brand.
