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.

--- Filtering efficiency: ISO Coarse 50%
As per compliance with eco design requirements
NBS-150
--- Fan group: 1, 2 or 3 motorised fans
--- Motor: 3 speeds
--- Volumetric flow: from 883 to 4697 m³/h
--- Static pressure: from 148 to 310 Pa
--- Cooling capacity: from 6.4 kW to 26.8 kW
--- Heating capacity: from 4.5 kW to 19.4 kW
--- Filtering efficiency: ISO Coarse 50% or ISO Coarse 60%
As per compliance with eco design requirements
OPERATION
The air to be treated is taken in by the fan ② on the
secondary air side ①, filtered in the filter section ③ and
conditioned in the heat exchanger ④.
