FXS-FLEX

Heat recovery unit WITH VERY HIGH EFFICIENCY HEAT RECOVERY,
FLEXIBILITY AND VERSATILITY DURING
INSTALLATION
from 250 to 3,000 m³/h

The FXS-FLEX series includes high efficiency heat recovery units for floor installation and high configuration flexibility. They are available in a vertical construction, and combine total freedom in the arrangement of air inlets/outlets in various positions (front/top/side), both a priori and on site. All this makes them an ideal product for internal installation in confined spaces or close to walls, with minimum obstruction.
The FXS-FLEX series comes in 5 models, with flow rates from 250 to 3,000 m3/h.
The FXS-FLEX range is equipped with an aluminium plate heat recovery unit, fans with EC motors and an integrated motorised by-pass system for free-cooling operation, in addition to the innovative KVir accessory for air sanitation with UV lamp and polyvin yl-amino matrix virus filter. In the FXS-FLEX range, the KVir accessory can be installed fully integrated inside the unit.
