Star’s Azanefreezer 2.0 exceeds UK performance guidelines with estimated cost savings of 66%.
The air cooled, low charge ammonia refrigeration freezer provides a simple packaged solution for cold storage and food manufacturing applications, such as blast and spiral freezing. The units range from 111kW to 650kW and are designed for low temperatures ranging from -18°C to -40°C. Multiple modules can also be used for larger applications.
The ultra-efficient Azanefreezer 2.0 technology is charged with as little as 0.52 kg/kW of natural refrigerant ammonia. The low-charge design reduces ammonia charge by up to 96% compared to traditional ammonia systems and avoids the need for complex valve stations. This removes the requirement for leak detection and ventilation, minimising health and safety concerns.
Recent energy performance data analysis for Azanefreezer 2.0 indicates its annual energy usage is one-third of that of UK’s ‘Best Practice’ guidelines and a quarter of that of European industry average.
Data from a recent Azanefreezer 2.0 installation indicates the cold storage operator is set to cut carbon emissions by 453 tonnes of CO2 per year compared to the UK’s ‘Best Practice’ guidelines. This saving rises to 815 tonnes of CO2per year when compared to the typical cooling demand of similar operational cold stores across Europe.
The simplicity of the pre-packaged unit provides a competitive solution, with recent experience suggesting a cost saving of at least 10% when compared to installing a traditional ammonia pumped recirculation systems. In addition, air cooled condensers avoid the need for water and chemical treatment which results in a further operating cost saving, since the costs associated with water usage, effluent and water treatment chemicals are eliminated.s.
The Azanefreezer 2.0 is manufactured and pre-commissioned at Star Refrigeration’s production facilities in the UK. When delivered to site, installation and commissioning time is reduced from 6 to 8 weeks due to the unit’s plug and play design, saving money and time.
The Azanefreezer 2.0 is also available for the North and South America market where it is manufactured and sold through Star Refrigeration’s low charge ammonia business, Azane Inc and joint venture CAz. For Information on our US Azanefreezer 2.0, visit www.azane-inc.com.
