Design Cooling Condition: Chilled Water In/Out 12℃/7℃;Ambient 35℃ Air Cooled Chiller Features:
1.With scroll, or reciprocating compressor of high quality, high efficient heat exchangers, excellent system design, by excellent process, the chillers is of suffient capacity and efficiency.
2.The chillers will work stably for long time period as they are produced by excllent process, composed of reliable control components and professional control procedure.
3. Units with V type heat exchanger: panels, frame and base are made from galvanized steel protected with polyester powder painting to ensure total resistance to atmospheric agents.
4. 3-phase scroll type compressor, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers.
5. 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.
6. Evaporator built with high efficiency tube in tube type heat exchanger, factory insulated with flexible close cell material.
7.Condenser built with seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins.
8. Refrigerant circuit complete with charge valves, filter drier, sight glass, gas-liquid separator, thermostatic expansion valve high & low pressure switch.
9. Hydraulic circuit built with galvanized pipe, complete with water discharge connection for tube in tube heat exchanger and flange type hydraulic connectors in two directions easy for connections from both sides of the units.
10. Electric panel consist of: compressor contactor, fan motor contactor, compressor protection breaker, fan protection breaker, phase sequence relay and microprocessor with function display (display only for master/packaged unit).
11. Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system.
12. Complete safety protection:
a. High&low pressure protection, pressure safety value protection;
b. Overload protection to the compressor;
c. Power supply protect for phase lack, counter phase, voltage too high and voltage deficient;
d. Water system protection for freezing breaking, water lack etc.
