AH Series Characteristic

The cooler element of the plate-fin heat type exchanger is superimposed aluminum and brazed in a furnace at controlled temperatures of around 600℃ Maximum dynamic pressure：20 bar. Maximum static pressure： 30 bar. Max. operating temperature：120℃ （Excluding the fan motor.） To protect the heat exchanger , when installed on the return line of a system or when the equipment is started with 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 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 , with the exception of oil cooling , it is recommended to consult our technical department .
