Improving the energy efficiency of ammonia, hydrocarbon and freon systems by reducing the condensing pressure

Quiet often the air enters the system during the operation of an industrial refrigeration unit. This greatly deteriorates the heat exchange and lowers the efficiency of the condenser, increases consumption of energy, lubricants and spare parts.

COOLTECH offers to solve this problem by means of installing an air purger to both new and existing refrigeration units.

Also COOLTECH PLC has developed a new high-performance air purger AP2, enabling removal of non-condensing gases like nitrogen, hydrogen, methane etc. from the refrigeration plants.  The AP2 Air purger is primarily meant for high capacity refrigeration plants and/or refrigeration plants with high refrigerant capacity. It’s also can be used for refrigeration plants operated on hydrocarbon gases, ammonia warehouses.

It’s also can be used for refrigeration plants operated on hydrocarbon gases, ammonia warehouses.

Advantages of the COOLTECH AP2 air purger:

  • May be used in explosion and fire hazardous environments (explosion proof design, Ex)
  • Capacity is two times higher than of the direct analogues and more than 20 times higher than of the autonomous air purgers of the well-known manufacturers
  • Can be used with any common refrigerants, including ammonia and hydrocarbons (propane, propylene, butane)
  • Reduces energy consumption of the refrigeration plant
  • Maximises cooling capacity of the refrigeration system
  • ensures accident-free operation of the plant in hot time
  • reducing refrigerant losses up to 98% compared to manual gas removal
  • suitable for refrigeration plants of any size
  • uses the same refrigerant as the existing refrigeration plant
  • minimal installation costs
  • very low power consumption
  • fitted with all necessary valves and automatics
  • fully automated operation (controller with LCD display)
  • dust and moisture protection not lower than IP54
