HEATING
SELECTION
Due to the range's extreme modularity, the selection has been optimised based on the thermal requirements and the allowable pressure drops for the fluids utilised. The importance of this factor must not be underestimated when selecting a heat exchanger, as it influences the choice and number of plates and thus the transfer area. The transfer area is also influenced by other factors, such as the height to width ratio, the gap between the plates, and the angle and depth of the chevron patterns.
ADVANTAGES
Excellent transfer coefficient, giving a reduced surface area. Very low pinch point temperatures possible. High corrosion resistance. Compact footprint. Easy to install and maintain. Low-capacity circuits and fluid retention volume. Option of surface area extension. Unit can be cleaned in-place using a circulation system (CIP). Maximum differential pressure = maximum operating pressure
PRECAUTIONS
Ensure the exchanger gaskets are not damaged (one per plate): Prevents overheating, water hammer and overpressure, and limits on-off cycles. Do not use 1/4-turn valves. Use with steam between 0 and 3 bar (effective). Provide a control system adapted to the requirements and which takes the low capacity of the circuits into account. Ensure the plates are kept clean so they maintain their thermal efficiency: Filter fluids containing suspended particles. Ensure the fluids are constantly circulating in the exchanger to prevent any build-up or scale. Install nozzles on the pipes for cleaning in place.
