The Air Process heater will provide hot air
and gas up to 1000°F (540°C) with infinite control by varying the voltage and air
velocity supplied. Units are fitted with a tubing "T" for convenient power lead
outlet, while larger diameters can be supplied with post terminals on the sheath for
direct electrical connections.
For easier installation, Hotwatt
can supply male or female NPT threaded fittings, hose adaptors, flanges, or custom
fittings to your specifications.

Determine the volume of air or gas (SCFM) you
will be heating.
Determine temperature rise in degrees
Fahrenheit (DeltaT in F)
Calculate wattage required as follows:
Take into consideration the physical size
requirements of your application and determine from the specifications chart for each
size, the air heater best suited for your application. High watt densities shown in the
specifications charts are subject to factory approval due to resistance wire limitations.
For temperature control see section Temperature Sensing Control
Whenever it is necessary to have a single unit incorporate two or more
different wattages, Hotwatt will provide air heaters from 5/8"
diameter and up with multiple circuits. Some uses of these units include: quick heat-up,
standby circuits for maintenance of low temperatures, providing different wattages when
there is a wide variation in thermal loads, and replacing more expensive variable
powerstats for wattage control.
Wattage tolerances are held to +5, -10% or better at the voltage
