The unit is formed of a set of stamped plates (P) and gaskets tightened between 2 plates, one ﬁxed (F) and one movable (B), using compression bolts (T). The gaskets (J) create ﬂow channels between the plates and prevent venting to the atmosphere. The connection for the ﬂuids is created by 4 tubes (M) integrated into the plate(s) or added.

Note: selection of single pass exchange is the only scenario in which the 4 tubes are ﬁtted on the same plate.
Double gasket between fluids
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. The thermal performance of 10TE heat exchangers is guaranteed.
Excellent transfer coefﬁcient, giving a reduced surface area Very low pinch point temperatures possible High corrosion resistance Compact footprint Easy to install 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
Ensure the exchanger gaskets are not damaged (one per plate): - Avoid water hammering and overpressure, and limit 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. 352 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.
