VIMATHERM PHE is a dismantlable Gasketed Plate and Frame Heat Exchange,
specially designed to guarantee the best operation and the longest lifetime for each of its components.
VIMATHERM
heat exchanger plates are pressed in one single stroke by large tonnage hydraulic presses.
This enables compliance to extremely tight tolerance, allowing large
plate packs to be perfectly aligned in when assembled.
The profile of the plates has been specially designed to generate high
turbulence, which guarantees high heat transfer rates and a resistance
to fouling higher than average.
Technology
VIMATHERM technologies
ensure one of the longest lifetimes for plates and gaskets and one
of the lowest life-cycle costs on the market, due to:
-
The gap between plates and the pressing depth are calculated to reach
the best compromise between thermal performances and fouling time.
-
The half-cylindrical gaskets technology allows the heat
exchanger to bear several operations of assembly and dismantling, and ensures the
original gaskets to last longer and limits the frequency at which these
parts should be replaced.
Why choose VIMATHERM heat exchangers
Most plate heat exchangers on the market use metal against
metal tightening technology. This technology compresses
definitively the gasket in its groove to its lowest tightening size, which means it
has to be changed as soon as the exchanger is dismantled for the first
times, in most cases.
VIMATHERM
technology allows all the exchangers of the range to have an average tightening size ex
works, which allows to adapt progressively the retightening of the
equipment after each dismantling, until it reaches its lowest
tightening size (contact metal/metal).
With this technique, plates are not tighten metal
against metal at the first assembly but only after several dismantleling operations. This
process protects the gasket and allows its re-use for several
maintenance and cleaning cycles.
This technology was achieved to fulfil industrial requirements, and allows
VIMATHERM heat exchangers to have one of the lowest life
cycle costs on the market (purchase price + operational costs).
