Liquid chillers cooling range from 79 kW to 518 kW serie AQUACOOL models VCN are the lates technology units dedicated for process cooling. Main features are: high energy efficiency ratio, multistage capacity regulation, silent work and ultra low refrigerant charge. It have been achieved thanks to high class scroll compressors, last generation of condenser fans and best in the market heat exchangers. 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.
Scroll compressors with an oil sight glass and electronic protection with thermistors in motor wiring. Refrigerant - R410A.
Brazed plate heat exchanger with one or two independent refrigeration circuits and one water circuit in all units. The evaporators are insulated with a flexible lining with a closed cell structure and covered with a special paint that protects against the effects of weather conditions and aging. 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 latest technology AC axial fans with thermal overload protection and speed control by means of electronic voltage regulator, IP54.
Each unit has two (except of VCN 90-180 models) independent refrigeration circuits. Each circuit is equipped with filter drier, sight glass, electronic expansion valve, service valves. Protection devices - HP and LP pressure switches, 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.
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.
Remote monitoring - Net package
All VCN units are equipped with a module that allows to view operating parameters and enables diagnostics using a web browser. In the event of an alarm, the user is notified by e-mail.
