CAIRplus Modular Units

The great flexibility of the CAIRplus® units is yet again proven by the application in clean rooms. The modular systems allows the units to be equipped according to the most severe clean room requirements.
For clean rooms, this consists primarily of a customized equipment selection to ensure optimum accessibility, durability and cleanability.
Clean rooms are often very unique environments and the selection of AHU equipment shall always be well thought through. A selection for a very demanding clean room setting can comprise for example:

• Sufficient number of service doors and spaces before and after the coils for maintenance and cleaning
• HEPA filters, as they are available in the highest filter class H14/U15
• Coils with Cu fins, since this variant is better resistant to e.g. aggressive cleaning agents and are sturdier for cleaning (the coils in the clean rooms need regular cleaning)
• Coils with coating: alodyne (lamellae) or immersion coating (entire coil). Here the selection also goes from class C2 to C5l-C5M and choose from several materials.
• Inner panels SS 304 or 316, which allows easy cleaning and generally provides a better protection against corrosion.
• Recovery system: although ECOROT rotation recovery systems have the highest efficiency, these are not suitable for clean rooms since the supply and extract air could be mixed in a very small quantity (<1%).
That is why it is best to opt for plate heat exchangers with enhanced sealing ECOPLAT H2, ECOPLATE-PLUS or ECOTWIN. The plates are coated. The use of liquid-coupled ERS Ecoflow is also a possibility. This system is absolutely contamination proof since the air flows are completely separated. For this system, several coating options are available as well: prepaint fins, immersion coating or säkaphen coating.
Each ERS shall be selected according to 4 standards: operation, maintenance, application and space available.

Great diversity of models
The enclosure design of the CAIRplus units is a combination of aluminium profiles and panels. In special cases, this especially sturdy construction even allows complete assembly on location. All panels, doors and flaps can be mounted and dismantled from the outside. In addition, a thermally separated design is also offered, providing the possibility – apart from a completely separation model – of thermally separating only the enclosure parts endangered by condensation.

Hidden technology, hygienic operation
The design of the CAIRplus air handling units optimally combines stability and functionality. Panel screw connections are made directly with the stable frame profile. The partition joint allows the connection of the delivered units at the construction site with only a few manual operations. The connection can be made alternatively from the inside or outside. The partition joint has no influence on the unit length. The cover strips, simple to disassemble with the screws lying on the outside, serve as seam sealing on weatherproof units and simultaneously ensure easy accessibility. No panel screws are employed inside. No frame parts protrude, ensuring an optimal prerequisite for hygienic operation. Flexible in design, the construction permits a high insulation class (T2/TB2) for minimal leakage (L1/F9) and high stability (D2) according to EN DIN 13779.

CAIRplus units are available with integrated cooling and control technology. Furthermore, different heat recovery systems are available. Our gratis Lplus software will help you with your optimal configuration of the units.
