AIR Handling UNITS

Construction

Housing

The construction of the central stations, independently of the size, is based on unied panel
elements, characterized by the width of 300-900 mm. Body panels are bolted. Bodies of KMW:
- climat air handling units distinguish themselves by:
- wall rigidity (folded panel is a self-supporting rigid structural beam),
- noise reduction (wall panels are lled with a wool characterized by a high sound reduction
factor),
- tightness (ensured by a special seal between the panels),
- easy to keep clean (the body has a smooth internal surface, with no
protrusions and bolts, easy to wash).

A skeleton construction, typical in most typical 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,
- makes easier the 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
onto the foundation. Optionally the air handling units are made without a oor - the housing
of the airhandling units are attached to the oor.

Standard

The design of the air handling unit fulls the requirements of the European standard:
PN-EN 1886:2007.

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.
