Liquid chillers serie AQUACOOL GREEN models VCG and VCGV with ecological refrigerant R290 ( propane ) are the latest technology units dedicated for process cooling. Main features are: high energy efficiency ratio , multistage capacity regulation, silent work. Application of R290 is an significiant advantage as this refrigerant has no influence to environment and is not a subject to the f-gas directive We offer different versions selected according to customer needs with varied accesories and options.
Self-supporting frame made of galvanized steel and protected with polyester powder paint.
Semihermetic piston compressors with an oil sigth glass and electronic protection with thermistors in motor wiring within VCG units. Possible option with an inverter drive. Compact screw compressors with an integral oil separator and step-less capacity control system in VCGV units.
The devices use plate exchangers with two independent cooling circuits and one water circuit. Evaporators are isolated. For safety, a differential pressure switch was installed to switch off the compressor in the absence of water circulation.
Heat exchangers - aluminium mocrochannel block with a very small internal volume. Coils are mounted in a V shape position within a robust strcture and connected according to the need of refrigeration circuits.
Fans - the lates technology AC axial fans with thermal overload protection and a funcion of speed control by mean of electronic voltage regularot, IP54.
Each unit has two (VCG 290HT and 360HT - 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. Modbus communication in standard.
