Electric Heater
Packaged Rooftop Cooling Only Units Heat Pumps and Gas Heating Units 4 stage electric heater can precise provide control of the indoor comfort and condition by meeting the heating load
of the building in cooling. Firstly, heat
pump units because four temperature limit
switches provide additional safety.
Secondly, It is supplied with shut-off valves
and 3-way proportional control
valve. Valve opening of 3-way valve
are adjusted according to supply
temperature and 100% modulated
(0-10 V) control can be achieved.
Moreover, frost protection thermostat
prevents the coil from freezing in
winter time.
Natural gas
heaters with high efficiency, low NOx
emissions and the latest condensation technology,
it is possible to keep indoor air in ideal conditions
in winter. Thanks to its flexible design and the supply air
duct connection can be made from bottom, top,
or side of the unit with a plenum, even if the
natural gas heater option is used.
With combustion efficiency up to 109% and condensing
technology and proportional control between 22%-100%,
it consumes natural gas at the rate of heating demand.
In Packaged Rooftop Cooling Only Units Heat Pumps and Gas Heating Units, 025-035-045-055 models are
used as standard with special high efficiency
compressors with inverter technology. 065-
075-090 units have 2 independent refrigerant
circuits each with 2 tandem compressors.
In this way, all models have an efficiency
higher than the seasonal efficiency values
of Ecodesign 2021. By means of inverter
compressors, it is possible to respond
more precisely to variable load demands.
preventing compressor on/off operation because
ın a conclusion, increasing the reliability of the cooling
system and ensuring longer operating life of
the compressors.
EC Plug Supply and Return Fans for the rooftops
EC plug fans are used as standard on supply
and return air side of the rooftops and in this
view, the air flow rate is automatically reduced
according to the demand because allowing the fans to
draw less power and naturally achieve higher
values in terms of seasonal efficiency.
The wide operating range of the fans allows to
meet all kinds of duct pressure drops and the
pressure of the building can be maintained at
the desired level thanks to the building pressure
control option. Finally,Thanks to the EC plug fans, air
flow rate can be monitored and changed any
time at start up or during operation of the unit
over Touch PilotTM.
