Azane offers 90% reduction in ammonia charge for freezer warehouse

Share Article

A leading wholesale frozen food company has upgraded its existing refrigeration plant with the installation of a low charge, air cooled Azanefreezer. The company supply the food service industry with a comprehensive range of fresh, frozen and grocery products.

The Azanefreezer has zero GWP and is exempt from EPA R22 phase out legislation

With a 25+ year life cycle and excellent seasonal efficiency, the system is a cost effective choice that will ensure our client remains competitive for decades to come.

The existing refrigeration system was in poor condition and was expensive to run – both in terms of energy cost and maintenance cost. Using a traditional pump circulation design, the system required a significant ammonia charge, which the client wished to reduce. A solution focusing on ammonia charge reduction was required - for improved safety, long term functionality and value for money.

The perfect solution was an AF70 Azanefreezer plant, to be installed as a replacement for the existing 40 year old equipment.

The high performance Azanefreezer boasts a range of eco-friendly benefits, including a low ammonia charge. Topping the list of benefits is the Azanefreezer’s capacity to reduce the freezer system ammonia charge from an estimated 5,000lb to just 360lb.

Derek Hamilton, US Business Development Manager, comments: "This drastic reduction in charge, in addition to the zero global warming potential and the use of a non-ozone depleting substance, is the future of refrigeration.”

“As a natural refrigerant system, our client has invested in a long term solution that will be exempt from any future environmental legislation laws. With a 25+ year life cycle and excellent seasonal efficiency, the system is a cost effective choice that will ensure our client remains competitive for decades to come.”

Modular, air cooled and inherently energy efficient, the new system will help to reduce running costs as well as combat greenhouse gas emissions.

The high performance system is both reliable and hardwearing, which will ensure continued levels of excellent customer service from this facility. Reduced operating costs are set to slash overhead expenses, while the reduced ammonia charge also lessens the regulatory burden for the site engineering team. The innovative modular design also allows for the easy and inexpensive relocation of plant if necessary.

Integrated into the system is an exclusive reverse cycle defrost function - currently the only system to offer this – which defrosts more efficiently that traditional hot gas or the alternative of installing electric heaters in the cooler.

The air cooled Azanefreezer is available in a range of capacities from 25TR to 100TR. All feature high efficiency EC condenser fan technology and fully integrated PLC control to ensure maximum efficiency at all times.

Azane Inc, a Star Refrigeration company, specializes in the manufacture of low charge, high efficiency ammonia packages. Azane’s range of cooling systems have been designed to provide a futureproof solution for the environmentally conscious. All Azane products are made in the USA.
