Technical Features
General
Pre-assembled waterproof single package, designed with R410A
refrigerant to save energy with high EER.
Heat pump with additional electrical heaters as an option if necessary.
A full run test is performed at the factory before shipping ensuring units
good working order.
Cabinet
Compact, light and single piece design.
All panels are made of galvanized steel. External panels and drain pans are
coated with powder-based epoxy paint (RAL9001) for improved weather
resistance.
Easy removable service panels for full unit access and ease of
maintenance.
Fork lift slots on the base rails to facilitate transportation and handling.
Fully insulated air treatment compartment with M1 polyethylene foam to
reduce energy loss, thermal bridge and sound disturbance.
Weatherproof technical compartment independent from airflows such
that running high and low pressures can be measured without disturbing
the normal unit operation.
Refrigerant equipment
R410A benefits
Higher heat transfer.
Environmental friendly refrigerant with zero ODP (Ozone Depleting
Potential).
Stable composition compared to R407C (2 refrigerant mixture instead of
3 with R407C).
Temperature glide less than 0.2 K during evaporation.
Smaller liquid line pipe.
Lower refrigerant charge.
Refrigerant circuit
Reversible refrigerant circuit designed for reliable operation in both cooling
and heating modes and composed of components optimized for R410A
refrigerant.
All refrigerant components are shown in the functional diagram illustrated
in "Refrigerant flow diagram" section.
Compressors
Each unit is equipped with one hermetic Scroll compressor for high
efficiency and robustness.
Compressors are mounted on rubber anti-vibration pads.
The motors, gas cooled type, are equipped with automatic reset internal
thermal protection.
Crankcase base heater is supplied on each compressor for improved start
up in winter.
Coils
Direct expansion coil type made of seamless copper tubes arranged in a
staggered row pattern. Each coil is mechanically expanded into aluminium
fins with full fin collars.
Condenser coil fins are hydrophilic coated for better water droplet
removing during defrosting cycles.
Fans
Air treatment side fans are single centrifugal wheels mounted on self-
aligning bearings.
On models 10 and 13 air treatment side fans are of multispeed direct drive
type.
On models 15 to 31 air treatment side fans are of belt driven type with
variable pitch pulley.
Available external static pressure goes up to 250 Pa (depending on
models).
On condenser side, units are equipped with direct drive propeller fans
consisting of plastic or painted steel blades. They are driven by single
phase motors.
Electrical box
All electrical equipment required for proper unit operation is located in a
weatherproof electrical control box including :
Main disconnect switch
Control circuit transformer
Phase controller (rotation and missing phase control)
Outdoor motor automatic reset thermal protection
Indoor motor contactor and thermal relay on models 15 to 31
Compressor contactor
CAC controller electronic control board.
Options and accessories
Factory fitted low ambient control to ensure cooling operation down to -10
°C outdoor temperature is available as an option.
Synthetic media type G2 (75%-80%) M1 air filter offered as a kit for field
installation.
Additional electrical heater for indoor installation on the air duct offered as
a kit for field installation.
RCW2 electronic programmable controller.
