The Azanefreezer range of air cooled condensing units have been designed to meet the environmental and legislative challenges facing users of temperature controlled storage facilities.
The Azanefreezer is ideally suited to, R22 system replacement, new build cold storage and extension of existing cold storage facilities.
Star Refrigeration’s Azanefreezer range of air cooled ammonia packaged units have been designed to meet the environmental and legislative challenges facing users of freezer warehouses.
The air-cooled range of Azanefreezers are complete refrigeration systems housed in one unit with separate ceiling mounted evaporators arranged for efficient reverse cycle defrost. Each Azanefreezer comprises of two open screw type compressors, a vertical oil separator, a low pressure receiver, a plate and shell economiser, an air-cooled condenser utilising VFD fan technology and an electrical control panel assembled onto a common fabricated steel frame. All interconnecting pipework, valves and wiring are included as part of the complete package.
Designed for industrial installations, the Bitzer screw compressor offers the following benefits:
The compressors are located for easy maintenance access.
IP55, high efficiency compressor drive motors are fitted to the entire Azanefreezer range. These motors are also specially designed to offer low noise operation.
All air-cooled Azanefreezers are fitted with low noise, variable speed fans to maximise system efficency at part load conditions. Fan speed varies depending on ambient temperature and condensing pressure. As fan power is proportional to the cube of the speed, a 10% speed reduction reduces power by 27%. Internal/external coil and fan guards are provided as standard to protect the condenser from damage during installation and operation and optional epoxy fin coating is available.
The Azanefreezer’s low charge, low pressure receiver (LPR) offers the following advantages over systems operating with pumped circulation, gravity feed or DX technology.
