Description of Device
The units are fired directly with heating oil or diesel.
They are designed for fully-automatic, universal and
reliable use.
The units are equipped at the factory with a large-
volume fuel preheater as well as a heating oil filter
protected from weather conditions. They are operated
with a separate forced-air oil burner and are suitable
for outdoor operation.
The units are equipped both with a high-performance
axial fan that requires little maintenance and inte-
grated switching and regulating units. They also have
an optical display which shows the individual operat-
ing functions.
The units have a sturdy framework design on robust
transport runners.
To ensure that the units can be operated over a pe-
riod of many years, particularly outdoors, the frame-
work and the lining plates are made of rust-proof
stainless-steel. In addition, all of the construction parts
inside the unit are also made of non-corrosive materials.
The compact design of the units makes them easy
and affordable to assemble quickly and guarantees
that they are easy to service.
The unit meets the basic safety and health require-
ments found in the relevant EU regulations and is
easy to operate.
*
The units are not designed for permanent fixed in-
stallation.
Locations for unit operation
The units are direct-fired, warm air heaters that supply in-
stantaneous heat. They are only used for commercial pur-
poses.
The units are used in the industrial area when portable
units are required to heat or regulate the temperature
of, for example:
– Warehouses
– Exhibition
spaces
– Trade
shows
– Large
tents
– Temporary structures for warehousing
– Large construction sites
There are generally no restrictions as to where they can
be used for temporarily heating buildings due to their
weatherproof design.
Functionality
If the unit is switched to heating mode, the forced-air oil
burner switches on automatically. The green “burner“
operating light is illuminated on the control panel for
monitoring purposes. If heating mode is controlled by a
room thermostat, the forced-air oil burner starts only
when heat is required.
Proper Use
These devices have been designed and equipped exclu-
sively to be used for heating and ventilation for industrial
and commercial purposes.
The manufacturer is not liable for any damage resulting
from non-adherence to manufacturer specifications, le-
gal requirements or any modifications to the units.
