TREVENT UKRAINE THANKS YOU FOR CHOOSING
TREVENT WATER FAN HEATER.

SAFETY MEASURES
Before carrying out any work related to the maintenance of fan heater, read
the following safety information.
SAFETY MEASURES 03
Foreign objects and liquids must not get inside the fan heater.
Before connecting the power supply source, check if the electrical
network parameters comply with the parameters for which the fan
heater is designed.
The electrical network that powers the fan heater and automatics
must be additionally protected from the phase loss.
Install the fan heater on a solid base that can sustain the weight of the
fan heater.
Check for grounding. Do not use the fan heater without grounding as
this may result in property damage, personal injury or death.
It is not allowed to use the fan heater with fully closed blinds.
The electrical network that powers the fan heater and automatics
must be short-circuit-proof.
Fan heater must be installed and connected to the utility networks
only by qualified personnel with the appropriate access and permits.
Observe all safety rules and regulations when installing, activating,
repairing, and servicing the fan heater.

The principle of operation of the TREVENT fan heaters is based on heating the air that
passes through the electric heater tubes (EHTs) of the fan heater through the use of a fan.
The TREVENT fan heaters are used for heating medium and large-scale facilities, such as
industrial shops, workshops, car showrooms, car washes, warehouses, pavilions, sports
facilities, and so on.
The TREVENT fan heaters are designed for indoor installation and operation in
recirculated air.
04 CHARACTERISTICS OF ELECTRIC FAN HEATERS SERIES
CHARACTERISTICS OF
ELECTRIC FAN HEATERS SERIES
The TREVENT EL-L series includes the fan heaters with smooth EHTs and directional
louvers for optimal warm air flow.
The TREVENT EL-L series includes the following:
• TREVENT EL-6-380L – fan heater with a rated thermal power of 6kW and line supply
of 220V.
• TREVENT EL-9-380L – fan heater with a rated thermal power of 9kW and line supply
of 380V.
Fan heaters have three stages of heating and a control panel with a TREVENT 6-9 L digital
thermostat. After stopping the heating, the fan continues to run for several minutes to
cool the EHTs.
The control panel is powered by a fan heater and is protected against short circuits by
the automatic circuit-breaker in the heater body.
The fan heater is protected from overheating by two self-healing thermal fuses that
temporarily turn off the EHTs when the body overheats, and a thermal fuse with manual
recovery that is activated at a much higher temperature and turns off the EHTs in an
emergency situation.
TREVENT EL-L SERIES
The TREVENT-EL series includes the fan heaters with ribbed EHTs and directional louvers
for optimal warm air flow.
The TREVENT-EL series includes the following:
• TREVENT EL-9-380 – fan heater with a rated thermal power of 9kW and line supply
of 380V;
• TREVENT EL-10,5-380 – fan heater with a rated thermal power of 10,5kW and line
supply of 380V;
TREVENT-EL SERIES

05
• TREVENT EL-12-380 – fan heater with a rated thermal power of 12kW and line supply
of 380V;
• TREVENT EL-22,5-380 – fan heater with a rated thermal power of 22,5kW and line
supply of 380V;
• TREVENT EL-30-380 – fan heater with a rated thermal power of 30kW line supply of
380V;
• TREVENT EL-36-380 – fan heater with a rated thermal power of 36kW line supply of
380V.
Fan heaters have two groups of EHTs and three stages of heating (except for models
with the power of 9kW and 12kW that have two stages of heating). Fan heaters are
equipped with control panels with built-in digital thermostats of ECONOM series for the
TREVENT EL fan heaters with the power of 9–12kW and the TREVENT EL fan heaters with
the power of 22,5-36kW, as well as EL series panels for the TREVENT EL fan heaters with
the power of 22,5-30kW and the PROG series panels for the TREVENT EL fan heaters.
Fan heaters are protected from overheating by two self-healing thermal fuses that
temporarily turn off the EHTs when the body overheats, and a thermal fuse with manual
recovery that is activated at a much higher temperature and turns off the EHTs in an
emergency situation.
After stopping the heating, the fan continues to run for several minutes to cool the EHTs.
In the TREVENT EL models with the power of 22,5-36kW, a ring bolt is provided for safe
lifting of the fan heater to a height.
ХАРАКТЕРИСТИКА СЕРІЙ ТЕПЛОВЕНТИЛЯТОРІВ

TREVENT ELECTRIC FAN HEATER
CONSISTS OF SEVERAL KEY PARTS
DIRECTIONAL LOUVERS with individual adjustment
provide the direction of a warm air stream. Directional louvers
have an aerodynamic profile that allows to receive low coefficient
of air flow resistance and, as a result, the maximum range of warm
air stream.
HEATING ELEMENTS (EHTS) installed in the TREVENT fan
heaters are made of copper and aluminum. For better heat pickup,
ribs that are spirally mounted on EHTs (width of a spiral is 8 mm)
were added to the heating elements. The frame for attaching EHTs
is made of galvanized steel.
Temperature sensors for protection of EHTs from overheating are
mounted in the upper and lower parts of groups of EHTs.
BODY consists of metal elements coated with highly resistant
polymer paint, galvanized fastening and structural elements.
FAN is located in a special diffuser in the rear part of the fan
heater so that the air flow is evenly distributed over the entire
surface of EHTs ensuring their most efficient use. This solution also
reduces the noise level created by the air. The fan is equipped with
a special small intake grille that protects the fan heater from
foreign objects and prevents possible injury to personnel by the
fan blades. Fan protection level IP 54 (EN 60529), insulation class F.
