AIR Handling UNITS

Construction

Housing

The construction of the central stations, independently of the size, is based on uni?ed panel
elements, characterized by a width of 300-900 mm. Body panels are bolted together. Body panels
of KMW climat air handling units distinguish themselves by:
- wall rigidity (bent panel is a self-supporting rigid structural beam),
- noise reduction (wall panels are ?lled with mineral wool characterized by a high sound dampening
factor),
- leak tightness (ensured by a special seal between the panels),
- ease of cleaning (the body has a smooth internal surface, with no protrusions and bolts, easy to wash).
A skeleton construction, typical in most of the produced central stations, has been eliminated
from the housing body structure. The panel construction is a self-supporting one:
- enables assembly in places which are dif?cult to reach,
- easier division of sections depending on transport possibilities inside the building
- ef?cient sealing and noise reduction.
The advantages of the system are as follows:
- airtight doors,
- inspection panels in any section.

Panel construction enables assembly of the air handling units on support frames or directly on

the foundation. Optionally the air handling units are made without a ?oor - the housing of the air
handling unit is attached to the ?oor.

Standard

The design of the air handling unit ful?ls the requirements of the European standard:
PN-EN 1886:2007 - Air conditioning air handling units - Mechanical requirements.

Workmanship class

Exceptionally rigid construction of the housing ensures minimum de?ection of walls during
start-up and operation, ensuring long, stable operation.

ZR air handling units ful?l high mechanical requirements described by the EN 1886 standard.
Mechanical characteristics of ZR air handling units exceed most requirements of the RAL
standards.
