Description
Liquid line valve (evaporator inlet) and
compressor suction line valve
Shut-off valve on the compressor
discharge piping
Reinforced evaporator for extension of the
maximum water-side service pressure to
21 bar (standard 10 bar)
Dual low-pressure water pump with
variable speed drive (VSD), pressure
transducers. Multiple possibilities of water
flow control. For more details, refer to the
dedicated chapter.
Dual high-pressure water pump with
variable speed drive (VSD), pressure
transducers. Multiple possibilities of water
flow control (expansion tank with built-in
safety hydraulic components available in
option)
Additional condenser coil to improve unit
energy efficiency
Additional condenser coil plus EC fans to
improve unit energy efficiency
complying with Lon Talk protocol
Bi-directional high-speed communication
using BACnet protocol over Ethernet
network (IP)
Bi-directional high-speed communication
using Modbus protocol over Ethernet
network (IP)
EMM Control board with additional inputs/
outputs. See Energy Management Module
option chapter
0-10 V signal to report any refrigerant
leakage in the unit directly on the
controller (the leak detector itself must be
supplied by the customer)
valves on the shell and tubes evaporator
Additional tests on the water heat
exchangers: Supply (additional of PED
documents) supplementary certificates
and test certifications
Thermal insulation of the evaporator
entering/leaving refrigerant lines with
flexible, UV resistant insulation
Coating by conversion process which
modifies the surface of the aluminum
producing a coating that is integral to the
coil. Complete immersion in a bath to
ensure 100% coverage. No heat transfer
variation, tested 4000 hours salt spray per
ASTM B117
Extremely durable and flexible epoxy
polymer coating applied on micro channel
heat exchangers by electro coating
process, final UV protective topcoat.
Minimal heat transfer variation, tested
6000 hours constant neutral salt spray per
ASTM B117, superior impact resistance
per ASTM D2794
Advantage
Allow isolation of various refrigerant
circuit components for simplified
service and maintenance
Simplified maintenance
Covers applications with a high
water column on the condenser side
(typically high buildings)
Easy and fast installation (plug &
play), significant pumping energy
cost savings (more than two-thirds),
tighter water flow control, improved
sytem reliability

Extended remote control capabilities
(Set-point reset, ice storage end,
demand limits, boiler on/off
command...)
Immediate customer notification of
refrigerant losses to the atmosphere,
allowing timely corrective actions
Valve replacement and inspection
facilitated without refrigerant loss.
