Removes Non condensable gases/ Air from refrigeration plants. Fully factory assembled unit. Can be used as multi point purger with  'Air Purger Controller' No need to install above condenser/ receiver. Can be installed in plant room/ ground level. 

Advantages of Airpurger:

1. Fully automatic gas purger for refrigeration plants
2. Automatic purger continually function to scavenge and remove air from System
3. Maintains condensing temperature at nearly optimum operating conditions
4. Reduces the concentration of non-condensable gases to a negligible Percentage
5. No need of separate refrigeration system
6. Eliminates the labour associated with personnel regularly removing air by manual operation

Spray galvanizing is used extensively for the corrosion protection of steel and iron in wide range of environments and has been shown to afford very long term protection in both marine and industrial locations. The life of the metal coating is proportional to the coating thickness. It is possible to increase the thickness to obtain enhanced corrosion protection. Zinc spray (galvanizing) coating can be applied in thickness from 50 microns to over 500 microns. Spray galvanizing is long term protection in industrial environments, coastal, offshore environments and high humidity atmospheres. The galvanizing coatings are effective for protecting mild, low alloy and high carbon steels. Steel can be protected by spray galvanizing followed by the one or two coat of epoxy painting can withstand aggressive environments like salt spray condition for long periods.

1. Render optimal corrosion resistance
2. Even coating
3. Timely execution

System Cleaner removes the Water, Dirt and Oil from Ammonia System that air purger leaves behind.

This boosts:

1. Lower Installation Cost
2. Self Regulating Operating
3. Shortest Payback Time
4. Energy-Neutral Operation
5. Very Low Maintenance

Air-purgers only removes non-condensable like air. If your air purger has been venting air, it's been leaving behind the water vapour that's always in the air. If your recirculating evaporator operating a few degrees warmer than the pressure indicates, this could be due to water in Ammonia. If water comes out of your oil pot before the oil, there is water in your system. You can easily measure the concentration of Water in your system with the graduated Ammonia Sampling Container.
