AQUACOOL GREEN – ecological liquid chillers with R290 refrigerant for application in technology and storage coldrooms. Cooling capacity 35- 388 kW ( data for MPG 35% -2/-8 oC)
Self-supporting frame made of galvanized steel and protected with polyester powder paint.
Semihermetic piston compressors with an oil sight glass and electronic protection with thermistors in motor wiring within VCG units.
Compact screw compressors with an integral oil separator and step-less capacity control system in VCGV units.
Brazed plate heat exchanger with two independent refrigeration circuits and one water circuit in all units.
Evaporators are insulated with flexible close - cell lining. A differential pressure switch installed for added safety in a case of no water flow.
Heat exchangers - aluminium microchannel blocks with a very small internal volume. Coils are mounted in a V shape position within a robust structure and connected according to the need of refrigeration circuits.
Fans - the latest technology AC axial fans with thermal overload protection and a function of speed control by means of electronic voltage regulator , IP54.
Each unit has two (VCG 290LT and 360LT – 4 circuits) independent refrigeration circuits . Each circuit is equipped with filter drier ,sight glass, electronic expansion valve, service valves. Protection devices - high pressure switch, low pressure switch, anti-freeze protection
Resistant to atmospheric conditions, protection class IP 54. Main components: emergency switch, main fuses, contactors of the compressors, contactors and fuses of the fans, auxiliary transformer and microprocessor controller.
