ACCESSORIES AND OPTIONAL EQUIPMENT
Expansion
valve
Thermostatic
(standard for IR and BR unit) with external equalizer, this supplies the evaporator correctly,
keeping the selected overheating degree at a steady level.
Electronic
(standard for IP and BP unit, optional for IR and BR unit) supplies the evaporator correctly, kee-
ping the selected overheating degree at a more steady level; ensures a faster response to load
changes and superior stability which translates into increased efciency at partial loads.
Soft starter Reduces the compressor start current of about 40%.
Compressor power factor correction
Allows to reduce the phase shift between the absorbed current and the power supply voltage
keeping it above the value of 0,91.
Fans control
On-off
(standard for AB unit) the condensation pressure (in cooling) and the evaporation pressure (in
heating) is regulated by on-off cycles.
Modulating control
(condensation /
evaporation control)
(standard for AS and AX unit, optional for AB unit) The fans rotational speed can be modulated
continuosly by an adjusting fan speed device to control the condensation pressure (in cooling)
and the evaporation pressure (in heating) in order to extend the operating limits of the unit, to
reduce noise emissions and improve energy efficiency.
Modulating control
(condensation /
evaporation control)
with EC fans
(optional for AB, AS and AX unit) The fans rotational speed can be modulated continuosly by
EC fans (Electronic Commutation) to control the condensation pressure (in cooling) and the
evaporation pressure (in heating) in order to extend the operating limits of the unit, to reduce
noise emissions and maximize energy efficiency.
Electrical
protecion load
Fuses Allows to protect the electrical loads with fuses.
Thermal magnetic
Allows to protect the electrical loads with thermal magnetic circuit breakers simplifying the
maintenance and reload operations.
