GENERAL DESCRIPTION
NBS room air conditioning modules are units with small
mounting height for decentralised air treatment. They are
particularly suitable for small units in which higher cooling
capacities and pressures are required than those that a
standard fan coil unit is able to provide. Additionally, NBS room
air conditioning modules outdo the performance of standard
fan coil units.
Its compact dimensions and low height make the NBS room
air conditioning modules the perfect solution for horizontal
installation in false ceilings or suspension-type mounting in
industrial halls.
The room air conditioning module series consists of two
product series, a modular unit (NBS -100) and a compact unit
(NBS -150), which can both be delivered, depending on the
desired performance profile, with different motor, register
and filter equipment.
NBS-100

AIR FILTER
The filter of efficiency ISO Coarse 50% or ISO Coarse 60% (for
type 150 only) consists of a galvanised steel frame and a
synthetic filter medium.
To facilitate maintenance work, the filters are guided in
profiles so that they can be easily removed by pulling them
out sideways or optionally also downwards or upwards.
To facilitate filter removal, SCHAKO offers a divided filter.

SILENCER
NOTE
Silencer is ordered and supplied separately.
For noise reduction purposes in the return air and supply air,
it is possible to install a silencer. The silencers are equipped
with vertically arranged flow-optimised silencing baffles. The
baffles consist of mineral fibre boards and are covered with
unmetabolisable glass silk, i.e. no bacteria can deposit on the
glass silk, and they are not flammable according to DIN 4102.
In order to reduce noise, while ensuring minimum pressure
loss, the length of the baffles and their spacing depend on the
desired silencing effect. The cover of the baffles can be made
of smooth or perforated plates, as desired, which can also be
combined on one or both sides or one or two half-covers. An
intermediate piece (box) of 500 mm is required between the
air outlet or the air intake of the NBS and the silencer.
Due to their device-related design, the baffle distance and
total length, SCHAKO's silencers provide an optimum
silencing value while ensuring minimum pressure loss.
NOTE
The technical data of the ZMWS-NBS can be found directly in
the MWS documentation or SCHAKO's selection programme.
NOTE
In cooling mode, silencers have to be insulated on the outside
with cold insulation.

PRESSURE INDEPENDENT CONTROL VALVES
1.- The volumetric flow [l/h] can be found in the technical
documentation or in the SCHAKO design program.
2.- Selection of the optimum valve. The valve must be
operated at approx. 80% of its VWmax.
NOTE
The valve and the actuator can be adjusted on site without
tools.
NOTE
The unit has no external condensate pan. The valves
must be thermally insulated on site.
