The heat exchange area is composed of stainless steel corrugated panels made and integrated by means of copper brazing. The exchanger operates following the principle of media flow in a parallel counter-current system. Evaporators A two-phase refrigerant is sent to the bottom connection on the heat exchanger refrigerant side. It becomes completely evaporated when flowing through the channels; simultaneously, it will acquire the requisite rate of superheating. Water or brine solution flows in counter-current way. Condensers Hot refrigerant vapours are sent to the top connection on the heat exchanger refrigerant side. They become condensed when flowing through the channels; simultaneously, they will acquire the requisite rate of sub-cooling. Similarly as in the case of evaporator, water or brine solution flows in counter-current way. DMF SYSTEM A unique system of dynamical distribution of the boiling agent - DMF system - has been developed by SECESPOL for evaporators featuring higher refrigerating effect. The system ensures a balanced distribution of the agent inside the evaporator channels and simultaneously reduces the fluctuations in vapour superheating. TYPICAL APPLICATIONS: - refrigerating units, - series of types for refrigerating effect: 1 - 500 kW,
