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, plate heat exchangers, heat pipes and liquid-coupled heat exchangers for
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
application for each case, CAIRplus units are designed for vertical or horizontal air flow
and are arranged as double-deck, side-by-side and 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.
Refer to the order-related documentation for the specific configuration of your CAIR-
plus unit (unit drawing with dimensions and technical data).
– Please carefully observe the unit type plate and the operation manuals for the sup-
plied accessories.
– Please refer to the accompanying documentation or technical specifications provid-
ed in the unit-layout software for the operating limits or related restrictions of individ-
ual built-in parts and components.
– The unit warranty is only valid if the specified materials are adhered to when units
are used in corrosive or aggressive environments!
– In process-air applications, consider the tolerance-related differences in aerody-
namic values!
– In frost-risk cases, use antifreeze agents for heating and cooling media.
– Operating limits for CAIRplus special/customized units are available on request.
