The GEA Purger increases the efficiency and improves the characteristics of every industrial refrigeration plant
Non-condensable gases cause considerable loss of efficiency. Air or other non-condensable gases can dissolve in the refrigerant and come into circulation in the refrigeration system, causing even in small concentrations a significant increase in condensing pressure due to their different/higher partial pressures. Refrigeration systems must therefore be kept as free as possible from non-condensables. The most effective way of doing this is by automatic purging, as this responds immediately to any entering of non-condensables in the system. The Self-limiting Automatic Purger is a purging device which reduces the concentration of non-condensables to a negligible percentage, with a just as negligible loss of refrigerant. This patented self-limiting Automatic Purger starts only when the concentration of non-condensables in the liquid receiver is 2% or more and stops when this concentration has dropped to below 1%. Since, in the entire installation, the average concentration of non-condensable gases is much lower, this represents an average concentration in the installation of less than 0.1%.
