The new generation of compact
air-conditioning units
The new generation of compact air-conditioning
units has been developed for
universal use in all hospital departments
and meets the requirements of DIN
1946-4.
Compact construction and innovative
technology ensure operating cost benefits
extending well into the future. The
optimised arrangement of mechanical
and dynamic-flow components ensure
low speeds and internal pressure losses.
Maximum ease of servicing
Very little outlay is needed for start-up,
maintenance and service. Thanks to
the compact housing and variable duct
connections, the units can even be set
up under unfavourable installation conditions.
The type designations reflect the field
of use of the air-conditioning units.
Performance features
Complies with DIN 1946-4
Nominal volume flow from
2.000 to 22.000 m3 /h
Full air-conditioning function with
heating, cooling, humidifying and
dehumidifying
Compact, single-module
construction
Filter class: F7 standard,
F9 optional
Two filter stages possible
Compact
Air-Conditioning Units

1 Housing
Double-shell wall construction with
45 mm thick insulation produces a
high degree of housing rigidity and
optimum sound absorption.
All-sided detachable housing lining
in keeping with DIN 1946-4
Interior of housing powder-coated,
bottom of housing as stainless
steel tub
Stable, low-maintenance and flexible
profile frame structure
Optional: vision panels for fan/filter
unit. They allow fans and filters to
be checked under operating conditions.
Electrical section, regulation, all-in
refrigeration components, humidifier,
PKW (Pumped Cold Water) or
PWW (Pumped Hot Water) valves
sealed off on the air side from the
air purification section – thus inspection
and maintenance possible
when the unit is running.
2 Fan motor unit
Efficiency of optimised heavy-duty
radial fan without spiral housing,
with blades bent backwards, aspirating
at one end
Drive motor as external impeller
integrated in the rotor – compact
design
Variable fan arrangement for maximum
blowoff position diversity
The fan speed is controlled via EC or
frequency converter in keeping with
individual pressure and volume flow.
Support-structured fan/motor unit
easily extractable from the front
3 Filter
F7/F9 Filter Class as cassette filter
Optional: bag filters possible with
downflow design

EC fan technology -
The best solution
We use modern EC fans in our compact
air-conditioning units. In contrast to
the usual AC fans, they have an EC
permanent magnet direct-current
motor.
Commutation with this new technology
involves semi-conductor modules -
thus electronic and non-wearing.
EC fan technology benefits:
High degree of efficiency
30 % saving in energy over AC fans
Vibration-free (oscillation-free
mounting)
Extremely quiet when running
Long service life
Infinitely adjustable speeds
Control/Regulation
with „pcs+"“
Weiss Klima compact air-conditioning
units are fitted as standard with a pcs+
control. Other control types on request.
Operating terminal
LCD display, 8 lines, 22 characters
6 keys with LED feedback
Warning horn
Front installation
IP 65 protection class
Integrated monitoring functions protect
both motor and electrical equipment
from the effects of blockage, phasing
failure and excess temperature and
thus ensure reliable operations and
long service life. Internal electrical
equipment continuously regulates the
air volume.
