R290 Compact screw compressors with an integral oil separator and step-less system of capacity control in HCS units.
Self-supporting frame made of galvanized steel and protected with polyester powder paint.
Brazed plate heat exchanger with two independent refrigeration circuits and one water circuit in HC / HCSL / HCS units. Evaporators are insulated with flexible close – cells lining. A differential pressure switch installed as a standard for added safety.
An advanced aluminium microchannel design, with ultimate performance and reduced refrigerant content / internal volume. A robust V shaped structured with easy, user-friendly access for servicing.
Using the latest technology AC axial fans with thermal overload protection and speed control by means of electronic voltage regulator, IP54.
H – Standard version
L – Low noise version – compressors in sound jackets, low speed condenser fans (or fans with low noise level), available in VC series
Each unit contain a single, two or four 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.
Power / Control
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.
