Recommendations for selection
The following recommendations on when to choose the MCHXE
treatment are based on the evaluation of the unit's installation
environment.
Will the chiller be installed in a
marine environment?
(minimum distance from the coast
20km, or even more if the direction
of the wind is mainly from the sea
and moves inland)
NO
Will the chiller be installed in
a rural/urban/industrial envi-
ronment with polluting agents
or potentially corrosive sub-
stances?
(refer to the manual
K20344 for further details)
NO
pollution in the chiller instal-
lation area?
(for example: animal farms, hospi-
tals, airports, volcanic areas)
NO
Protection against corrosion of MCHX
The layer of natural aluminium oxide is very strong/thick and acts as
protection against corrosion to the underlying metal. This does not
all applications and conditions. This depends on the corrosiveness of
the environment.
There are different anti-corrosion protective coatings on the market
suitable for HVAC components. Many of these have proven to be
heat exchanger, only certain coating solutions are advisable.
Rhoss offers the E-coating treatment solution with the MCHXE
accessory.

is a UV resistant technology and suitable to protect MCHX from
aluminium corrosion with 100% coverage, without solution of continuity.
The thickness of the coating layer is 15-30 micron, minimising the loss
