HLV Series
Tube Heater
Vacuum System
Vacuum type tube heaters are negative pressure gas-
fired infrared heaters designed to provide comfort
heat. They consist of four (4) main components: a
burner control box, radiant tube, reflector assembly,
and vacuum exhauster. The heaters are typically
suspended from the ceiling by chains and controlled
by a thermostat. They can be installed either vented
or unvented, and may use outside air for combustion
if necessary. The radiant tube may be installed in
different configurations depending on the heating
requirements.
These heaters use infrared energy to heat spaces.
When heat is required, the burner control box ignites
a gas/air mixture and the vacuum pulls the hot gases
into the radiant tube. As the gases pass through the
assembly, the tubing is heated and emits infrared,
which is then directed toward the floor by reflectors.
This is known as primary infrared and is absorbed by
the floor, objects and people in the space, raising their
temperatures. They in turn reradiate this heat, known
as secondary infrared, to create a comfort zone at the
floor level. This is how tube heaters can heat large
spaces without having to provide primary infrared for
every square foot of area. However, if the goal is to
spot heat a small area within a large space, only the
primary infrared makes this possible. Vacuum tube
heaters are design certified for use in industrial and
commercial buildings, such as warehouses,
manufacturing plants, aircraft hangars and vehicle
maintenance shops. No heater may be used in a
class 1 or class 2 explosive environment. Unless
otherwise indicated, they are not certified for
residential use or where flammable gases or vapors
are generally present, such as spray booths.
