OPTIONS
Mechanical Options – On request
20mm evaporator insulation (opt. code 29)
The heat exchanger is fitted with 20mm closed cell insulation material - Opt. incompatibility 08.
Discharge line shut-off valve (opt. code 61– Multi-V units only)
Installed on the common discharge pipe of the compressors to facilitate maintenance operation (one discharge
valve per refrigerant circuit).
Suction line shut-off valve (opt. code 62– Multi-V units only)
Installed on the common suction pipe of the compressors to facilitate maintenance operation (one suction valve
per refrigerant circuit).
Discharge and Suction line shut-off valve (opt. code 126– Single-V units only)
Installed on the common discharge and suction pipes of the compressors to facilitate maintenance operation (one
discharge and one suction valve per refrigerant circuit).
Alarm from external device (opt. code 70)
The unit controller is able to receive an external alarm signal. The user can decide whether this alarm signal will
stop the unit or not.
Fans circuit breakers (opt. code 96)
Safety devices that, added to the standard protection devices, protect fan motors against overload and
overcurrent.
Water filter (opt. code 115)
The water filter removes impurities from water by means of a fine physical barrier. It must be installed on the
water pipe connceted to the heat exchanger inlet.
The filter is shipped loose together with two victaulic joints and two counter pipes to be welded on the plants.
NOTE: The installation of the filter is mandatory.
Total Heat Recovery (opt. code 01)
A plate to plate heat exchanger for each refrigerant circuit is installed in series to the condenser coil. There is
no switch nor solenoid valve in the circuit, thus compressor discharged refrigerant is always flowing through the
heat recovery exchanger and hot water production is always available while the chiller is providing cooling.
During the operation in heat recover the condenser coils provides the sub-cooling ensuring the right amount of
liquid at the inlet of the expansion valve. The unit controller manages the condensing temperature set point in
order to maximize the cooling effect and amount of energy recovered.
The amount of heat recovered is about the 80/85% (according to the operating conditions) of the total heat
rejection of the chiller. The chiller performs the control on the recovery circuit, based on the return water
temperature to the unit. Heat recovery capability is subject to cooling load demand (if no cooling demand is
present then no heat recovery is available) - Opt. incompatibility 03. Not available on the following models:
EWAT085B-SSA1, EWAT085B-SLA1, and EWAT085B-SRA1.
Partial Heat Recovery (opt. code 03)
A plate to plate heat exchanger for each refrigerant circuit is installed in series to the condenser coil. There is
no switch nor solenoid valve in the circuit, thus compressor discharged refrigerant is always flowing through the
heat recovery exchanger and hot water production is always available while the chiller is providing cooling.
During the operation in heat recover the condenser coils provides the sub-cooling ensuring the right amount of
liquid at the inlet of the expansion valve. The unit controller manages the condensing temperature set point in
order to maximize the cooling effect and amount of energy recovered.
The amount of heat recovered is about the 15/20% (according to the operating conditions) of the total heat
rejection of the chiller. The chiller performs the control on the recovery circuit, based on the return water
temperature to the unit. Heat recovery capability is subject to cooling load demand (if no cooling demand is
present then no heat recovery is available) - Opt. incompatibility 01. Not available on the following models:
EWAT085B-SSA1, EWAT085B-SLA1, and EWAT085B-SRA1.
Brine Version (opt. code 08) - Opt. incompatibility 29-142
For operation with temperature at the outlet of the evaporator below +4°C the unit must operate with glycol
mixture (with ethylene or propylene glycol) and the Brine Version option must be selected. Brine version
includes additional insulation on evaporator surfaces.
Evaporator flange kit (opt. code 21)
Opt. incompatibility 20.
