Oil Cooling Applications
The brazed heat exchanger is the type of heat exchanger that offers the best performance, most efficiently in oil cooling applications. Except for situations where the capacity is very high or the temperature is beyond the operating limits of these heat exchangers, the preferred choice of heat exchanger for oil cooling is brazed heat exchangers. However, if these specified conditions exist, tube heat exchangers can also be preferred. MIT Brazed Heat Exchangers, which provide high and efficient performance thanks to their efficient, durable, and compact structures, are covered by a 2-year warranty by Ekin Endüstriyel.
General Features of Brazed Heat Exchangers
Plates and connections are made of AISI 316 standard stainless steel, vacuum brazed with copper 1.4401. The special design plates that provide turbulent flow required for effective heat transfer have a high level of mechanical strength.
Environment
