PACKAGED ROOFTOP UNITS 48EN/EH 241-600
Options
■■ Compressors in tandem. This setting improves the
management of stages, and therefore the energy
efficiency of the unit.
■■ Dampers with spring for automatic closing in case of a
tension cut. This is compulsory if the outdoor temperature
is lower than -8ºC WB.
■■ Assembly with mixing box and free-cooling:
2 dampers (motorised):
-- MS: Outdoor air intake with damper, interlocked with
return damper.
3 dampers (motorised):
-- MA: Axial return and air extraction fan with duct (to
prevent recirculation).
-- MC0: Lower MC0 radial centrifugal return fan.
■■ Electrical heater for antifreeze protection of dampers
of mixing boxs. This is compulsory if the outdoor
temperature is lower than -12ºC WB.

Designation of the assembly
R = Air return
I = Air inlet
N= New air inlet
E = Air extraction
0 = Standard
S = 2 dampers
A = Axial return fan
C0 = Radial centrifugal return fan
■■ High-powered axial fans in the outdoor circuit.
■■ Electronic EC axial fans in the outdoor circuit which adapt
their rotation speed to the installation requirements,
thereby reducing electricity consumption, the sound level
at partial charge and improving the average seasonal
output of the unit.
■■ High-pressure outlet fan of the indoor circuit (for available
pressure above 30 mm.a.c). Centrifugal fans, coupling by
pulleys and belts with an impeller with back-curved blades.

■■ Condensates drain pan for the indoor circuit in stainless
steel (standard pan in galvanised steel).
■■ Control of the overpressure with the MC0 assembly.
■■ Soft starter of the outlet fan which prolongs the set time
mainly aimed at installations with cloth ducts. Compulsory
for motors with an output of 15 kW and above.
■■ Stop-drop in the outdoor air intake.
■■ Gravimetrics filters G4.
■■ Opacimetric folded filters F6 to F9 + gravimetric filters G4.
■■ Differential pressostat for clogged filter detection
(recommended).
■■ Electrical power supply with neutral.
■■ Outdoor coil protection grille.
■■ Coils (outdoor and/or indoor) with copper pipes and
copper fins.
■■ Coils (outdoor and/or indoor) with copper pipes and
aluminium fins with polyurethane and blygold polual coating.
■■ Thermal and acoustic isolation 50 mm thick, with fire
classification Euroclase A2-s1, d0.
■■ Compressor with protection for low temperature
(supplementary crankcase heater). This is compulsory if
the outdoor temperature is lower than -8ºC WB.
■■ Numeration of components in the electrical panel.
■■ Numeration of wired.
■■ Smoke detecting station in accordance with the NF S 61-961
standard.
■■ Air quality probe for installation in the environment or in
duct to enable measuring CO2 and/or volatile compounds.
■■ Standardised pre-assembly frames made of galvanised
steel panelling, thermally insulated. Adjustable height.
■■ Shock absorbers made of rubber.
■■ Skis for transporting in closed container.
CONTROLS
■■ Electrical heater for protection of the components of
the electric panel. This is compulsory if the outdoor
temperature is lower than -8ºC WB. With an outdoor
temperature ower than -16ºC WB will be compulsory a
reinforced resistance.
■■ Energy meter.
AIR TREATMENT
I
■■ Tropicalised unit. It includes varnish for the elements in
the electric panel, tropicalised indoor and outdoor fans.
