Description
Advantages
Use for POWERCIAT LX
ST / HE / XE
Medium-temperature
brine solution
Implementation of new control algorithms and redesigned
evaporator to allow chilled brine solution production down
to -6°C when ethylene glycol is used (-3°C with
propylene glycol)
Covers specific applications such as ice storage and
industrial processes
●
Low-temperature brine
solution
Implementation of new control algorithms and redesigned
evaporator to allow chilled brine solution production down
to -12°C when ethylene glycol is used (-8°C with
propylene glycol)
Covers specific applications such as ice storage and
industrial processes
●
Light-brine solution,
down to -3°C
Implementation of new control algorithms to allow chilled
brine solution production down to -3°C when ethylene
glycol is used (0°C with propylene glycol)
Matches with most application requirements for ground-
sourced heat pumps and fits with many industrial processes
requirements
●

ST / HE version, sizes
1308 to 4608
IP54 control box
Increased leak tightness of the unit
Protects the inside of the electrical box from dusts, water and
sand. In general this option is recommended for installations
in polluted environments
●
Tropicalisation of the
electrical box
Electrical box equipped with an electrical heater and a
fan. Electrical connections on the compressor painted
with a special varnish.
Allows safe operation in typical "tropical" climate. This option
is recommended for all applications where humidity inside the
electrical box can reach 80% at 40°C and unit can remain in
stand-by for a long time under these conditions.
●
Protection grilles
Metallic grilles on the 4 unit sides.
Improves protection against intrusion to the unit interior, and
protects the coil and piping against impacts.
●
Winter operation down
to -20°C
Fan speed control via frequency converter
Stable unit operation for air temperature down to -20°C
ST version, all sizes
230V electrical plug

Liquid line valve (evaporator inlet), compressor suction
and discharge line valves and economiser line valve
Allow isolation of various refrigerant circuit components for
simplified service and maintenance
●
Compressor discharge
valves
Shut-off valve on the compressor discharge piping
Simplified maintenance
●
Evaporator with one
pass more
Evaporator with one pass more on the water side
Optimise chiller operation when the chilled water circuit is
designed with low waterflows (high evaporator delta T)
