Unit description
The units are stationary, directly
fired fan-assisted heaters (WLE)
with heat exchanger and exhaust
gas connection.
The units can be directly fired with
EL heating oil, diesel fuel, liquid
gas or natural gas.
The units must also preferably be
operated with biomass fuels to
ensure environmentally friendly
unit operation. The following
biofuels are permitted:
- Biodiesel B7/B10
(FAME content less than 10%);
- Hydrogenated vegetable oils
(HVO; compliance with
DIN EN 590 required)
The units are designed exclusively
for operation with separate fan
burners.
For the safe discharge of exhaust
gases above the roof, the units
must be connected to a suitable
exhaust system.
The units are equipped as standard
with 1-stage, low-noise/low-
maintenance centrifugal fans and
with attached and electrically wired
switching and control devices.
The switching and control devices
consist of a fan controller (TR),
two temperature monitors for
controlling the outlet temperature
(TW1/TW2) and a safety
temperature limiter (STB). In the
following, these units are described
as "controller unit".
NOTE
The units are not suitable for
the heating of living spaces
or the like.
Locations at which units are
used
As directly fired fan-assisted
heaters (WLE), the units deliver
instant heat.
The units are designed exclusively
for industrial or commercial use.
The units can be equipped with air
ducts on the intake/outlet side if
designed accordingly.
As a rule, there are hardly any
restrictions on their use with regard
to the installation location.
The units may be used among
other things for the following:
■
Heating / temperature control
of workshops
■
Heating / temperature control
of warehouses
■
Heating / temperature control
of event halls
■
Heating / temperature control
of exhibition halls
■
Heating / temperature control
of lightweight-construction
halls
■
Heating / temperature control
of sales rooms
■
Heating or frost protection in
garden/agricultural outbuildings
The units are to be used
exclusively for industrial and
commercial applications. They
are not intended for the heating
of living spaces or the like.
!
CAUTION
The robust construction and
careful processing of the units,
which are made exclusively of
high-quality materials, guarantee
many years of trouble-free
operation.
Further plus points are the simple,
fast and cost-effective installation
and service-friendliness of the
units.
The units conform to
the fundamental health and safety
requirements of the appropriate
EU stipulations, and are simple
to operate.
