To protect the heat exchanger, it should be installed to the return line of the systems or when the equipment is started up running by the cold oil, a by-pass valve should always be mounted in parallel to the exchanger in order to avoid excessive pressure surges.An alternate piping method is using a separate circuit from the reservoir with a small pump to drive the oil through the heat exchanger.

Filters are often incorporated into these side circuits or kidney loops, as they are sometimes called.

For all applications, except oil cooling, it is recommended to consult our technical department.
