for process cooling and refrigeration

Liquid chillers serie AQUACOOL GREEN VCG,VCGV i SWG MINI 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.

Features

Structure

Self-supporting frame made of galvanized steel and protected with polyester powder paint.

Compressors

Semihermetic piston compressors with an oil sigth glass and electronic protection with thermistors in motor wiring within VCG and SWG MINI units. Possible option with an inverter drive. Compact screw copressors with an integral oil separator and step-less capacity control system in VCGV units.

Evaporator

The devices use plate exchangers with one or 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.

Condenser

Heat exchangers – vertical copper aluminium or aluminium microchannel block with a very small internal volume. Microchannel coils are mounted in a V shape position within a robust structure 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.

Refrigeration circuit

Each unit has one up to four independent refrigeration cirucits. 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.

Electric box

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.

Hydraulic module P/2P, PH/2PH

Basic hydraulic kit includes single pump - P or double pump - 2P (the other pump is a stand-by one), expansion vessel, pressure gauge, safety valve, shut-off valve. PH - pump with higher head pressure. Piping is insulated.

Hydraulic module ZP/Z2P, ZPH/Z2PH

Version with a basic hydraulic kit P/2P and an insulated inertial storage tank; available for VC series units.
