The Carrier 42GW hydronic cassette offers a modern solu-    
tion for a wide variety of small and medium sized commer-    
cial and residential applications.     
It is ideally suited for large offices, data centres, shops,     
restaurants and bars, hotel receptions, meeting rooms,     
photographic studios, banks, laboratories and showrooms.     
As the units have connections for fresh air ducts they can     
ease problems caused by smoking. The 42GW is normally     
installed in suspended ceilings and offers two, three or four-    
way air diffusion. The units maintain precise temperature     
and humidity conditions preventing draughts and stale air     
zones. The elegant air inlet grille blends aesthetically with     
any room decor.     
The Carrier hydronic cassette is available in six sizes with     
cooling capacities from 2.4-11.0 kW and heating capacities     
from 4,0 to 14 kW, suitable for a wide range of applica-    
tions.     
The units can be supplied from a chiller, a heat pump or a     
boiler, satisfying a wide range of design requirements.     
System installation is fast and economical.     
Features     
■ Four-way air distribution gives individual comfort while for     
localised control each diffuser may be adjusted or even shut     
down completely.     
■ The unique design of the centrifugal fan ensures extra-quiet     
operation.     

■ The special design of the diffuser ensures rapid blending of     
the supply and room air. Conditioned air is directed along     
the ceiling then evenly distributed throughout the room.     
Return air enters the cassette unit through a large grille. It is     
then cleaned by an easily removable, washable synthetic     
filter, treated and recirculated.     
■ State-of-the-art high performance filters to extract impuri-    
ties from the air. Washable filters are supplied as standard.     
In addition, electrostatic and activated carbon filters are     
also available as optional extras to reduce airborne bacte-    
ria, dust, pollen and smoke or odours respectively.     
■ High-performance condensate drain pump encased in a     
special sound-insulating material removes condensate     
quietly and fast.     
■ The low-profile 42GW is light and easy to install. The     
small chassis fits neatly with standard ceiling tiles and is     
simple to install wherever it is needed.     
■ All the key components are accessible from the bottom,     
simply by removing the grille. The fan can also be removed     
without disturbing the other components or any surround-    
ing ceiling tiles.     
■ Four different control options are available with different     
levels of technical sophistication to ensure maximum user     
comfort.     
■ Units available in three versions:     
42GWC: 2-pipe version     
42GWD: 4-pipe version     
42GWE: 2-pipe version with electric heater

The above data refers to Eurovent conditions.

Cooling conditions: 27°C db/19°C wb entering air temperature, 7°C/12°C entering and leaving water temperature at high fan speed

Heating conditions (2 pipes): 20°C entering air temperature, 50°C entering water temperature, same water flow rate as in cooling, at high fan speed. Heating conditions (4 pipes): 20°C entering air temperature, 70°C/60°C entering and leaving water temperature at high fan speed.

*  Air flow values are for units with filters. They do not apply to ductable units.

** The electric motors are 3-speed hermetic type motors with permanent capacitors. They are suitable for tropical climates.
