The Pneumatic Cold/Hot Source of AIR –H series is a new type of air-conditioning product using the compressed air as working medium. As a significant breakthrough in the freezing industry, it is capable of both heating and freezing by means of a brand-new freezing method, which is under the protection of the national patent. The patent was granted in March, 2002. The patent No. is ZL 01 2 08844.7.

With its remarkable freezing capability, it forms a continuous and adjustable Temperature flow below -26℃at its central outlet of cold end, whereas above 80℃at that of hot end.

The product is composed of a group of static metal parts which is able to conduct a normal operation in the adverse and harsh circumstance where other types of air conditioner can not work.

Even under the high temperature of 60℃, buried in the dust or submerged in the water the product can keep proper working for 5 years plus without repair and maintenance free.

Such product can be widely applied to the industries such as metallurgy, mine, electric power, chemistry and military, especially under the adverse and harsh circumstance, or whereno availability of power supplies.

• Energy saving: No need of power supply and additional power actuating device
• Environmental affinity: Air as working medium, free of leakage risk of hazardous gas
• Care free: No movable parts, rid of mechanical wear, long lasting continuous working without maintenance
• Superior adaptability: Most suitable in harsh environments of high temperature, high humidity, and heavy dust or under rough conditions with explosive and flammable hazards
• Convenient usage: easy in installation and operation, irrespective of power supply, leakage risk of conventional freezing medium and the space availability for heat radiation
