2.0 INTRODUCTION
The UNI-X ceiling void unit range is designed to provide mechanical
supply and extract ventilation with heat recovery, which incorporates an
automatic HX bypass feature.
The units are fitted with two high efficiency centrifugal fans with EC Motors,
which have speed control over three different ventilation rates; trickle, boost and
max. A counterflow plate heat exchanger is also used to recover up to 85% of
the extracted air heat, whilst G3 Filters provide protection to the unit and ensure
filtered air is supplied, guaranteeing the unit is ErP 2018 compliant.
The HX bypass damper shall open automatically via a wax actuator allowing the
air to bypass the heat exchanger to deliver fresh filtered air during the warmer
months.
General information regarding performance and specifications for the
equipment may be obtained from our Technical Literature, and/or project
specific documentation.
