2. Standard Product Configuration
•Reliable reciprocating type compressor for medium and low temperature models with oil sight glass
•IP54 rated control panel
•Magnetic contactor (Note: except single phase medium temperature application condensing unit).
•External shut off valves for quick installation and easy access and maintenance.
•Weather proof housing made of epoxy coated steel
•Corrugated aluminium fin and inner groove hairpin condenser
•Liquid receiver is sized to accumulate refrigerant amount up to 25m piping length during pump down.
Fusible plug on the liquid receiver to protect system from exploded when ambient temperature goes
higher than 1000C
•Oil separator and non-return valve for low temperature models
•Sight glass and flare type filter drier
•Dual pressure switch to protect compressor
•Designed for zero ozone depletion potential (ODP=0) refrigerant R404A (available for all range
condensing units) or R134a (available for medium temperature application condensing units).
•The condensing unit is fully factory tested and is filled with nitrogen in order to always ensure the
highest quality of our products.
