MODELS
Low-pressure single-pump
hydraulic module
Low-pressure single pump, regulating valve,
Victaulic couplings,
fi
lter and all necessary
hydraulic devices. Refer to speci
fi
c chapter.
Quick start-up on job site. Available
pressure around 150 kPa.
High-pressure single-pump
hydraulic module
High-pressure single pump, regulating valve,
Victaulic couplings,
fi
lter and all necessary
hydraulic devices. Refer to speci
fi
c chapter.
Quick start-up on job site. Available
pressure around 250 kPa.
Low-pressure twin-pump
hydraulic module
Low-pressure twin pumps, regulating valve,
Victaulic couplings,
fi
lter and all necessary
hydraulic devices. Refer to speci
fi
c chapter.
Quick start-up on job site. Available
pressure around 150 kPa.
High-pressure twin-pump
hydraulic module
High-pressure twin pumps, regulating valve,
Victaulic couplings,
fi
lter and all necessary
hydraulic devices. Refer to speci
fi
c chapter.
Quick start-up on job site. Available
pressure around 250 kPa.
Partial heat recovery
Plate heat exchanger on each compressor
circuit allowing recovery of 20% of the rejected
heat
Allow free hot water production
simultaneously with unit operation
Total heat recovery (Free
hot water : 100% heat
recovery)
Recovery brazed plates heat exchanger dual-
circuit mounted in parallel to the air condensers
allow 100% heat recovery in all outdoor air
conditions.
Production of free hot water at the
same time of the production of chilled
water.
Free cooling
Additional free cooling coils (one “V” or two “V”
depending on needed capacity) with inverter
fans and motorised valves.
Allow the chilled water to run through
the free-cooling system, which uses
less power and utilises the lower
ambient air to cool the water.
Winter operation (from +6°C
down to -20°C) – Cooling
only units
Unit
fi
tted with electronic expansion valve and
variable frequency driven fans. Select “anti-
freeze protection” option if no glycol water
Increased operating range in
cooling down to -20°C ambient
temperature. (Standard on sizes
540/600/640/1080).
Brine operation (From +5°C
down to -10°C)
Unit
fi
tted with electronic expansion valve,
variable frequency driven fans and reinforced
evaporator and piping thermal insulation.
Increased operating range in
cooling down to -10°C water leaving
temperature for thermal storage or
process cooling.
Anti-freeze protection (down
to -20°C)
Resistance heaters on the evaporator,
hydraulic module and partial heat recovery if
selected. To be selected if no glycol water.
Evaporator and hydraulic module
frost protection down to -20°C
ambient temperature
Anti-freeze protection
of Total Heat Recovery
exchanger
Resistance heater and insulation of the
recovery exchanger, to be selected if no glycol
water.
The recovery exchanger have frost
protection down to -20°C ambient
temperature.
Heavy anti-corrosion coil
treatment
Application of LenGuard treatment on the
entire coil surface.
High corrosion resistance for
severe industrial, marine and dirty
environments.
Rear protection grille
Metallic grille
fi
tted at the back of the unit
Prevents the rear V-coil against
possible damage
