Principle of the Osram Sylvania Hot Air HeaterThe basic principle is to blow air trough a
tubular stainless steel equipped with an inside heating element made of FeCrAl wire.
The wire is coiled in a special way (porcupine) and place on threaded ceramic the whole is
installed in a ceramic or quartz insulated tube.
This system allow to reach a maximum heat exchange and calories transfer in a minimum space
From this combination we have a compact air heater with a very low thermal inertia.
The construction is such that power leads at the inlet of the heater are always cold.
The hot air at the exit of the tube could be very very high in temperature, for some
application with 2 heaters installed in series
we can reach an exit air temperature of 1100°C. This applies for small power.
Controllable, fast response, high temperatureThanks to this advance technology the yield
of your process will be improved due to:
• Heater power will be concentrated to the exit outlet
• Possibility to adapt specific nozzles and flares without to much heat losses
• Low thermal inertia
• Great versatility to be installed
It’s low thermal inertia contribute to save energy |
