Cold comfort for food manufacturers.Star Refrigeration's new Azanechiller is an ammonia packaged chiller developed for environmentally conscious end users. Ammonia has zero ozone depletion potential The ozone depletion potential (ODP) of a chemical compound is the relative amount of degradation to the ozone layer it can cause, with trichlorofluoromethane (R-11) being fixed at an ODP of 1.0. Chlorodifluoromethane (R-22), for example, has an ODP of 0.05. and zero global warming potential Global warming potential (GWP) is a measure of how much a given mass of greenhouse gas is estimated to contribute to global warming. It is a relative scale which compares the gas in question to that of the same mass of carbon dioxide (whose GWP is by definition 1). .

A substance, such as air, ammonia, water, or carbon dioxide, used to provide cooling either as the working substance of , Azanechiller offers exceptional efficiencies across a wide range of operating conditions. Sales Director Rob Lamb comments: "The Azanechiller typically offers a 20% increase in performance compared with standard HFC 1. (networking) HFC - Hybrid Fiber Coax. 2. (hardware) HFC - hydrofluorocarbon. chillers. Its packaged design and careful component selection result in an ultra low refrigerant charge, with all ammonia contained within the chiller and outside the production facility or warehouse. This means a refrigerant charge as little as 0.1kg per kW." As a complete refrigeration package, Azanechiller is easy to install and each unit comes pre-charged and tested. Only an electrical supply and flow/return pipework is required to provide cooling. Rob Lamb adds: "Azanechiller is ideally suited for retrofit projects where customers typically have limited space for new plant and need to keep project costs to a minimum. The packaged design offers customers the flexibility to relocate the chiller to meet their ever-changing cooling requirements." Star developed the Azanechiller range of ammonia packaged chillers to meet cooling requirements in a wide range of markets. Suitable for cooling both water and glycol, Azanechiller is ideally suited to applications in food processing, temperature controlled storage, building services and process cooling. Azanechiller features high quality, industrial components to offer unrivalled performance, reliability and low maintenance. Each unit includes two screw compressors, low noise drive motors, Star's low charge, low pressure receiver and semi-welded PHE evaporator. Azanechiller is available as an air-cooled or water-cooled unit with cooling capacity from 200kW to 850kW. Air-cooled Azanechillers feature high efficiency EC condenser condenser Device for reducing a gas or vapour to a liquid. Condensers are used in power plants to condense exhaust steam from turbines and in refrigeration plants to condense refrigerant vapours, such as ammonia and Freons. fan technology. Water-cooled Azanechillers include a welded plate heat exchanger The plate heat exchanger (PHE) was invented by Dr Richard Seligman in 1923 and revolutionised methods of indirect heating and cooling of fluids. A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. evaporator to minimise refrigerant charge. Both chillers include floating header pressure control, which optimises efficiency at part load conditions and low ambient temperatures. Food and drink manufacturers with cooling equipment operating on R22 are just six months away from a ban on the use of virgin refrigerant for servicing and topping up. The final phase out date for R22 and other hydrochlorofluorocarbon Noun 1. hydrochlorofluorocarbon - a fluorocarbon that is replacing chlorofluorocarbon as a refrigerant and propellant in aerosol cans; considered to be somewhat less destructive to the atmosphere HCFC (HCFC Noun 1.

This means a loss through leakage could be both costly to replace and result in prolonged plant downtime if the refrigerant is unavailable from suppliers.
