ELECTRIC HEATERS IBE - 2 Pages

Electric heaters
IBE Series
Designed to be installed on the fans
discharge side.
The minimum air speed through the
heater must be 2 m/s.
Maximum air temperature through the
heater: 40ºC.
The batteries are fitted with:
- Armoured heating elements to connect
to the three phase net (3x400).
- Double protection circuit to connect to
the battery control circuit by means of
a safety overheat automatic thermostat
(60º), connected in series with another
safety overheat manual reset thermostat
(RESET).
- Wiring box IP43.
Available temperature sensors in the
duct, ambient temperature sensors
and speed controllers to complete
the installation and to adjust the air
temperature according to every need. By
means of this system the supplied air can
reach up to 50º.
(See the electrical accessories section).

SELECTION EXAMPLE
DATA:
- Airflow: 3300 m3/h (Q)
- Temp. of supplied air: -5ºC
- Temp. of exhausted air: 20ºC
HEATER BATTERY POWER REQUIRED:
P = Qx0,36x∆T = 3300x0,36x(20-(-5)) = 29700
W=29,7 kW
