Osem Logistics Centre, Shoham
Industrial CO2 refrigeration plant - the first of its kind in Israel and a world class pioneering endeavour.
Overview
Osem’s new and advanced logistics centre has been designed to meet stringent international standards as dictated by the Nestlé concern.
The facility is unique in being specified as green and sustainable, restricted to the exclusive employment of natural refrigerants: the primary refrigerant being ammonia, with water, propylene glycol and carbon dioxide as secondary refrigerants - for air conditioning, refrigeration and deep freeze systems.
More Information
Ammonia as a green refrigerant:
Ammonia is energy efficient and environmentally friendly; a special feature of the plant is in the smaller than usual quantity of ammonia used, restricted to the technical area only on account of its being a hazardous material.
Carbon dioxide (CO2) as a green refrigerant:
Carbon dioxide, replacing ammonia as a secondary refrigerant in the deep freeze system, is energy efficient, environmentally friendly and non-toxic.
The installation consists of a two-stage primary ammonia system with an overall output of some 6,000 kW (1,700 TR) offering 3 temperature levels: -2°c for cold water heat exchangers; -12°c for glycol heat exchangers; -32°c for CO2 heat exchangers.
The ammonia compressor system comprises 3 Frick screw compressors, 5 Sabroe reciprocating compressors and 4 BAC evaporative condensers.
The air distribution systems include 24 Goedhart fan coil units and 12 air handling units in an insulated panelled structure.
The duct system includes black steel ammonia piping with full radiographic photo standard welds, stainless steel CO2 piping with full photographic argon welds, clean pipe work standard.
Operation, adjustment and commissioning carried out by Mashav technicians qualified for the purpose by Frick and Sabroe, who supplied professional supervision.
