AIR-COOLED SCROLL CHILLERS WITH
GREENSPEED INTELLIGENCE 30RBM/30RBP 160-520
®
From an energy efficiency point-of-view the MCHE is
approximately 10% more efficient than a traditional coil and
allows a 40% reduction in the amount of refrigerant used
in the chiller. 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 is very fast using a high-pressure washer.

Novation® Aluminium Micro Channel
Heat Exchanger
The Novation® features the latest generation of Carrier Micro
Channel Heat Exchanger ( MCHE) with new extra resistant
aluminum alloy. Already utilised in the automobile and
aeronautical industries for many years, the MCHE is entirely
made of aluminum. This one-piece concept significantly
increases its corrosion resistance by eliminating the galvanic
currents that are created when two different metals (copper
and aluminum) come into contact in traditional heat
exchangers. Unlike traditional heat exchangers the MCHE
can be used in moderate marine and urban environments.
COOLING
The AquaSnap also communicates with other building
management systems via optional communication gateways.
A connection terminal allows remote control of the AquaSnap
by wired cable:
-- Start/stop: Opening of this contact will shut down the
unit
-- Dual set-point: Closing of this contact activates a
second set-point (example: unoccupied mode).
-- Demand limit: Closing of this contact limits the
maximum chiller capacity to a predefined value.
-- Operation indication: This volt-free contact indicates
that the chiller is operating (cooling load).
-- Alarm indication: This volt-free contact indicates the
presence of a major fault that has led to the shutdown of one or several refrigerant circuits.
