Housing
Base Solution: Frame made of painted galvanised steel heavy profiles
to ensure total mechanical and corrosion resistance. Integrated
solution: Base made of painted galvanised steel; panels made of
galvanised steel externally coated with plastic (PVC) film fixed in
a aluminum frame. Panels are internally lined to reduce the noise
level (LN Accessories only).
Compressor
HERMETIC SCROLL type, complete with thermal protection.
Antivibration mountings and oil charge are standard.
Water heat exchanger
Plate-type made of AISI 316 steel complete with water differential
pressure switch. Shell covered with closed-cell neoprene anti-condensate
material.
Electrical board
Switchboard to standards IEC 204-1/EN60204-1, complete with
contactor and protection for compressor. Main isolator and door
interlock safety device.
Control
The microprocessor controls the unit capacity by timing the compressors
and checks the operating alarms with the possibility to
connect to BMS.

tank, water pump, water tank.
Remote condenser
Units of this series are provided for the matching with an air cooled
remote condenser of the CTK.E series (with axial fans) or CTK.C
(with centrifugal fans). Condensers are supplied with maintenance
charge of nitrogen.
Refrigerant charge
The condenserless units are shipped with a maintenance charge
of nitrogen.
