SONDEX
has developed and designed a whole new generation of plates heat exchangers. The construction is based on many years of experience. The demand made to SONDEX Plates had been that of high efficiency and flexibility together with the demand for suitability in high differential pressures.
The inlet part
The design of the inlet part is provided with sloping lead grooves which guarantee the even distribution of liquids across the plate pattern. The result is that the so-called ?dead spots?, which could cause the growth of bacteria in the plate heat exchanger, are completely avoided.
The Plate pattern
The plate pattern chosen by SONDEX is the fish bone pattern. Even at low liquid speeds this pattern gives maximum turbulence and thereby an extremely effective heat transmission. SONDEX plates can be obtained in two different designs, respectively thermally short and thermally long. The two different designs have their own special thermal characteristics with regards to pressure drop and thermal efficiency.
Edge reinforcement
In order to reinforce the gasket groove the SONDEX plate is designed with edges on both sides of the gasket groove. On the inside with a corrugated edge. This design ensures that the plate is solidly supported and at the same time it gives a good hold on the gasket.
The gasket
The design of the gasket ensures, even after prolonged clamping of the plate heat exchanger, that it does not loose its elasticity. The gasket is, in the inlet area, designed as a double gasket, with a drain area, meaning that the mixing of the two liquids is impossible.
The plate lock
The plate is designed with a lock, causing the plates to lock into each other when the plate heat exchanger is clamped together, so that they do not slide when working at large pressure variations. This feature also secures proper assembling of the plate stack.
Differential Pressure
The plates are constructed with the necessary number of support points, thereby ensuring stabillity, even at high differential pressures.
