Oil Cooling Applications
Soldered exchangers are the type of exchanger that offers the best performance in the most efficient manner for oil cooling applications. Except in cases where the capacity is very high or the temperature is outside the working limits of these exchangers, the primary choice of exchanger for oil cooling processes is made from soldered exchangers. However, if these specified conditions exist, tubular exchangers can also be preferred. Efficient, durable, and with compact structures, MIT Soldered Heat Exchangers are covered by a 2-year warranty by Ekin Industrial.
General Features of Soldered Exchangers
The plates and connections are made of stainless steel in accordance with AISI 316 standards, and are vacuum-welded with 1.4401 copper. Special design plates that provide the turbulent flow required for effective heat transfer have a high level of mechanical resistance.
