SEC174

Rising Film Evaporator

Description

Recommended Applications

The SEC174 Sondex plate evaporator is a specially
developed heat exchanger for evaporation
duties.

Design Principle

The plate is designed as a semi-welded cassette,
with a welded channel for the medium side, and
on the evaporation side there is a traditional
plate heat exchanger gasket.

The unique plate design ensures an even
distribution of the product over the whole plate
making optimal rising film evaporation. The
special designed plate pattern ensures a high
turbulence of the fluids on both sides, resulting
in a high heat transmission co-efficient. This
results in a very compact heat exchanger with a
small hold-up volume.

Installation:

The large DN600/24” connection on the
evaporator makes it possible to cover many
duties in a single connection solution. This
means that the connections will be on the head
of the heat exchanger, which is of big advantage
during service work and if the capacity is to be
increased.

The plate pattern and inlet area are also
designed for CIP cleaning, which makes the
service of the plate heat exchanger easy.

Data Required for Correct Quotation:

• Duty

Gaskets

The gasket is placed in the closed gasket

groove, that is formed by the plates. This
design makes the plate suitable for high
working pressures. The plates are strongly
guided by the gasket during the assembly of

the plate heat exchanger.
