The Region’s Trusted Distributor of Plate & Shell Heat Exchangers
Plate and shell heat exchangers (PSHE) combine the pressure and temperature capabilities of a cylindrical shell with the excellent heat transfer performance of a plate heat exchanger. The round plates ensure an even distribution of mechanical loads, without the stress concentrations that occur in the corners of rectangular plates.
The design of the plate and shell heat exchanger is similar to that of a radiator or water heater, but it differs in that the water passes through two separate circuits—one for heating and one for cooling.
The shell side of the plate and shell heat exchanger contains a series of tubes with fins that are submerged in an oil-based fluid. This fluid circulates throughout the system, absorbing and releasing heat from the tubes as needed. This process also helps to keep the tubes from overheating by transferring excess heat into the oil-based fluid as it flows through them.
The plates on the other side of this device are made out of either steel or aluminum alloy material which serves as both an insulator and a conductor. They also contain small holes or tubes through which air can pass through so as not to overheat during use; however, these holes should be kept clear at all times so as not to damage any other parts within their reach (i.e., heating coils).
