The CRH-XHE packaged air-conditioning units are installed outside the
spaces being served. They come in various capacities and with a vast range
of accessories. They are intended for the air-conditioning of large rooms or
areas and are applied in closed or open loop water systems.
Designed to reduce work on site to a minimum, these units have been created
for continuous operation with maximum energy saving through an extremely
intelligent, advanced management of energy, supplying it only when and
where needed. They are extremely versatile units with three airflow settings:
standard, high and reduced.
The high efficiency of the innovative refrigeration circuit,
optimized for functioning at partial loads, the free-cooling and the energy
recovery of expelled air available as an option on the whole range, allow
to reduce energy consumption and therefore the management costs and the
emission of carbon dioxide.
