-- Automatic compressor unloading in case of
abnormally high condensing pressure. If an anomaly
occurs (e.g. fouled air heat exchanger coil, fan failure)
AquaSnap continues to operate, but at reduced
capacity.
■■ Exceptional endurance tests
-- Corrosion resistance tests in salt mist in the laboratory
-- Accelerated ageing test on components that are
submitted to continuous operation: compressor
piping, fan supports
-- Transport simulation test in the laboratory on a vibrating
table.
COOLING
All-aluminium micro-channel heat
exchanger (MCHE)
Already utilised in the automobile and aeronautical industries
for many years, the MCHE micro-channel heat exchanger
is entirely made of aluminium. This one-piece concept
significantly increases its corrosion resistance by eliminating
the galvanic currents that are created when two different
metals (copper and aluminium) come into contact in traditional
heat exchangers.
As an option, the Enviro-Shield and Super Enviro-Shield
anti-corrosion protections have been developed to increase
the application range of the MCHE coil from medium to very
corrosive environments. With Enviro-Shield protection,
corrosion resistance of the MCHE coil is doubled without any
impact on heat exchange.
With Super Enviro-Shield protection corrosion resistance of
the MCHE coil is multiplied by four, and allows use in very
corrosive industrial or marine environments
The MCHE heat exchanger allows a reduction in chiller
refrigerant charge by up to 50%.
The low thickness of the MCHE reduces air pressure losses
by 50% and makes it less susceptible to fouling (e.g. by
sand) than a traditional coil. Cleaning of the MCHE heat
exchanger is very fast using a dry air jet or a high-pressure
washer, while observing the usage precautions.
