USA: Star Refrigeration announce the launch of a new subsidiary US Company Azane Inc. to manufacture and supply it's “low-charge ammonia” Azane technology.
The industrial refrigeration group, who developed the unique technology, Azanechiller and Azanefreezer to meet the environmental and legislative challenges that the cooling industry was facing as Europe started the phase-out of ozone depleting refrigerant R22.
The technology is being introduced to the US market at a key time, just as the US refrigeration industry begins to see the effects of the Environmental Protection Agency's R22 phase-out program. The EPA's phase-out timetable for R-22 will gradually decrease its production until a complete ban comes into force in 2020. The cost of R-22 will continue to rise and existing R-22 refrigeration systems will become uneconomical long before it is banned completely.
The Azanechiller and Azanefrezeer are factory-built industrial refrigeration packages which are both highly efficient and environmentally conscious. The design uses patented technology to deliver the lowest cost of ownership by minimizing running costs over 25 + years.
All Azane packages use the natural refrigerant ammonia and have been designed to operate with as little as one tenth of the charge of a traditional refrigeration system, therefore avoiding the burden of OSHA's PSM and the EPA RPM requirements.
Ammonia is also future-proof. A natural refrigerant widely used for its environmentally friendly credentials -zero ODP and zero GWP- it is not under threat of being banned, unlike HFCs.
Derek Hamilton, US Business Development Manager at Azane says:
"The good news is that there are plenty of options available to allow a smooth transition away from R-22. Low charge ammonia is one of a number of options available and we are always happy to talk to our customers and guide them through the various options. There are a wide range of 'drop in' refrigerant options are available, this typically consist of blends of hydrofluorocarbons (HFCs)."
Derek Hamilton adds, "In the USA, the use of ammonia has historically been restricted to large, distributed refrigeration systems. These systems are typically site-installed and require a central machinery room to house the refrigeration equipment. These systems also tend to use 'pumped circulation' technology that requires a relatively large quantity of ammonia.
"The advent of 'low charge ammonia' means that ammonia is now being considered in applications which were typically the domain of 'commercial' systems. These commercial systems often use the HFC refrigerants mentioned above. Some users of HFC systems may be reluctant to switch to an ammonia system because of safety concerns, however the reality is that ammonia systems in general are very safe and the low-charge, packaged approach alleviates these concerns further by using the minimum amount of ammonia and ensuring that it stays within the refrigeration system."
