3 Technical Description
3.1 Performance scope
CAIRplus units are generally used for energy-saving supply-air and extract-air indoor
ventilation. Due to their modular design, units can be configured individually to meet
particular air-handling requirements and specifications. The transported air can be fil-
tered, heated, cooled, humidified or dehumidified, depending on the application for
each case. The aim is to meet the customer specifications concerning required air vol-
ume and conditions.
CAIRplus units are used at a central point for comfort air conditioning on commercial
and industrial premises for the transportation and treatment of “normal” air. The units
can also be manufactured in a customized design and adapted for cleanroom and
hygiene applications. CAIRplus units meeting explosion-protection standards and
complying with the ATEX 94/9/EG Directive are clearly designated and marked. These
units are supplied with an additional operation manual that must be read and consid-
ered.
A range of unit components are available for energy-saving purposes: rotary heat
exchangers,plateheatexchangers,heatpipes andliquid-coupledheat exchangersfor
the recovery of heat and the partial recovery of moisture as well.
Units are performed in different sizes and have various capacities. Depending on the
applicationforeach case, CAIRplus units are designed for vertical or horizontal air flow
and are arranged as double-deck, side-by-sideand straight-through models. Units can
be installed indoors and outdoors.
Thanks to the modular design of the CAIRplus, units ship as complete assemblies or
sub-assemblies that can pass through the available on-site openings in the course of
installation. CAIRplus units are also suitable for the modernization and retrofitting of
existing buildings due to the number of available unit sizes and a unit ordering option
providing for delivery in small shipment units.
