All about the natural refrigerant ammonia (NH3) in cooling & refrigeration: News, Products, Jobs, Events, Knowledge, Forum, B2B Networking.

Although the potential of real ammonia innovations was relatively low at the China Refrigeration held in Beijing this year, numerous companies were showcasing or developing products using NH₃. Companies such as Parker showcased established purgers or new ammonia compressors. +IMAGE GALLERIES

This year, the theme of Asia’s largest trade show for the HVAC&R industry is “Stay on the Cutting Edge of the Industry, Make Contribution to Low-carbon Emission". Choosing this topic, the organisers aim to demonstrate the exhibition's determination in promoting the healthy and sustainable development of the HVAC&R industry. Ammonia refrigeration is also in the Asian market seen as one possible solution to lower CO₂ emissions.

Ammonia companies and products

Parker: Similar to the model the global leader in motion and controls showcased in San Diego at the IIAR conference, Parker presented its Auto Purger Model V200. It is designed for removing efficiently foreign non-condensable gases from ammonia refrigeration systems. The lightweight purger features a proprietary microprocessor control for all sensing and control functions. In addition, Parker displayed a hand valve for ammonia applications at the key event in Asia for the HVAC industry.

Yantai Moon: The Chinese company manufactures compressors for various applications, mainly for the food processing industries and beverage companies. With a growing international business Yantai Moon will also focus more on ammonia products and had already 4 screw compressors for ammonia on display.

In addition, the company presented its compound double-stage screw refrigerating compressor unit with 4 rotors, which was developed by Yantai Moon using the national-patented efficient rotor profile. The unit operates efficiently and economically with different refrigerants, including NH3. The compressor integrates a double stage compression refrigeration circulation and two stage capacity control and high automation. In 2009, it won the Science Technology Award of China Mechanical Industry.

ammonia21.com talked also with representatives about the company’s corporate message “cherish earth”. They confirmed that natural refrigerants are expected to be the future, especially as governments around the world phase out Freons.
