Liquid chillers AQUACOOL F VCF i VCGF , with ecological refrigerant R290 or R410A are the latest technology units using climatic conditions to implement free cooling, so-called FREE COOLING. AQUACOOL F chillers, thanks to their special construction in the form of a built-in additional air-liquid exchanger with full control package, are characterized by significantly reduced average annual electricity consumption compared to a standard chillers. These chillers are designed for refrigeration and show their best advantages in high-temperature process cooling.
Self-supporting frame made of galvanized steel and protected with polyester powder paint. Placing the blocks of condenser and free-cooling as a "double-skin" structure enables to minimize the unit foot-print.
VCGF series - semihermetic piston compressors, R290
VCF series - scroll compressors, R410A
All compressors with an oil sight glass and electronic protection with thermistors in motor wiring.
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 block 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 lates technology AC axial fans with thermal overload protection and a function of speed control by means of electronic voltage regulator, IP54.
One (VCF90-180) or two 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 IP54. Main components: emergency switch, main fuses, contactors of the compressors, contactors and fuses of the fans, auxiliary transformer and microprocessor controller RS485. Modbus comm. card and real time clock card as standard equipment.
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.
