Heat Exchanger
High efficiency or condensing boilers have a heat
exchanger that uses heat in the flue gases to pre-heat
water. The condensed water is drained away and much
less energy is required to raise the temperature of the
preheated circulating water to the desired level.

Requirements:
· The seal has to compensate diameter differences
of 1.2 mm between plastic and metal case
· Gap on connector flange of 0.3 mm and a bent groove
· The seal has to compensate for the non-central
positioning of the spiral tubes related to the flange
entry holes
· Low assembly forces of the housing
· Easy assembly for all seals
· Good resistance to aggressive condensate (acid)
· Temperature -20°C to +130°C
· Customer provided 3D CAD files for all housings
and counter parts

CASE STUDY
Specially for you
Engineered Molded Parts
Uniquely yours
Trelleborg Sealing Solutions offers one of
the broadest ranges of sealing elements on
the market. Most of the time the tried and
tested method works, but sometimes a unique
application requires a unique solution.
Our specially designed sealing solutions can
provide significant benefits from a cost, function,
manufacturing or performance perspective,
providing you with real competitive advantage.
Working with our engineering teams, Trelleborg
Sealing Solutions will support you in the
development of a customized engineered
molded part designed to suit your individual
needs. This may be a flat gasket of any
dimension, a rubber-to-metal element or a seal
of complex geometry that may consolidate a
number of products into one.
