Ammonia Screw Compressor Units USC
USC ammonia screw compressor are fully integrated packaged units designed to work in refrigeration systems. The unit’s construction is compact and does not require special foundations. It is possible to supply shock absorbers together with the compressor unit, which ensure high efficiency of damping vibrations transferred to the ground.
- Options
-
- Screw compressor - with two asymmetric rotors
- Electric motor - squirrel cage (at the customer's special request we offer motors with permanent magnets)
- Flexible coupling – metal
- 3-stage horizontal oil separator with special coalescing elements, effectively separating oil from gas.

Packaged air-cooled ammonia chillers based on screw compressors, with a 290–1,500 kW capacity range
Ammonia air-cooled chillers are based on plate-and-shell evaporators with integrated liquid separator, microchannel air-cooled condenser and screw compressors. Frequency converter and panel solutions are supplied as standard. Units are designed with a low ammonia charge basis. There are 6 different standard models in this range high- and low-temperature versions. Units are for outdoor installation so no need for the ammonia machine room.
- Options
-
- Variable-speed drive (VSD)
- Soft-starter or Y/D starter
- Control panel mounted separately
- Economiser option
- Integrated cascade heat exchanger for subcritical CO2 low-temperature application
Packaged water-cooled ammonia chillers based on screw compressors, with a 315–3,200 kW capacity range
Packed ammonia water-cooled chillers are based on plate-and-shell heat exchangers (evaporator with integrated liquid separator and combined condenser with integrated oil cooler) and the screw compressors. Frequency converter and panel solutions are supplied as standard. Units are designed with a low ammonia charge basis. There are 9 different standard models in this range high- and low-temperature versions. Units are for outdoor or indoor installation (outdoor option with external housing).

Propane
Chillers with R290 refrigerant and integrated free cooling module
Refrigeration units operating on the basis of the environmentally friendly R290 refrigerant, also known as propane, are modern cooling devices designed for process cooling installations. They offer exceptional efficiency, precise multi-stage performance control and very quiet operation. This product line includes versions tailored to a variety of investor needs, along with a wide selection of optional upgrades. The devices use plate exchangers with one or two independent cooling circuits and one water circuit. The evaporators are insulated. For safety, a differential pressure switch is installed that turns off the compressors in the event of lack of water circulation.
- Options
-
- Inverter speed control of fans
- Vibration isolators
- Superheat heat recovery
- Side cover panels
- EC fans
- Soft start
CO2
Transcritical CO2 condensing units for low temperature applications with a capacity range of 30kW - 500kW
Solid frame construction, painted with epoxy powders. The principle of operation of the standard version is based on a gravity-flooded evaporator, which allows for better temperature control and lower energy consumption. Use of a natural refrigerant such as CO2 (R744) with zero OPD, GWP = 1. Reversible version, with dedicated logic to optimize COP based on the required water temperature. Highly efficient coalescing oil separator with an inspection flange enabling periodic filter replacement.
- Opcje
-
- Heat recovery (single- or double-wall exchanger)
- Pump module for heat recovery
- Evaporator module
- Factory tanks up to 800 liters capacity
- Emergency cooling unit
