Unit description
The units are portable, directly
fired fan-assisted heaters (WLE)
with heat exchanger and exhaust
gas connections exclusively
for commercial applications.
The units are directly fired with EL
heating oil or Diesel fuel.
The units can be operated with
or without exhaust gas pipe
(depending on the conditions
on the customer's side).
They have been designed
for universal and straightforward
use.
The units must be exclusively
operated with separate type-
approved forced-air WLE-type
burners.
The units are equipped with
a noise-optimised and low-
maintenance, high performance
radial fan, a room thermostat
receptacle and a mains cable with
a 230 V shock-proof plug or HTL
170 with 400 V CEE plug.
The HTL 170 units are equipped
with a device for automatically
checking the turning direction
of the fan motor, as standard.
With factory fitted forced-air oil
burners the HTL 170 units have
integrated REMKO Multiflex oil
pre-heating fitted as standard.
With the HTL 80 this is available as
an option (EDP no. 1071411) .
The units conform
to the fundamental health
and safety requirements
of the appropriate EU stipulations
and are simple to operate.
Operating sequence
If the units are set to heating
mode, then the forced-air burner
starts automatically. In fully
automatic heating mode with
room thermostat the forced-air
burner starts only when heat is
required.
After the burner has run for a short
time the temperature controller
"TR" (target temperature ca.
40°C) switches the supply air fan
on automatically.
Warm air is blown out.
When operating with a room
thermostat this process is
repeated automatically depending
on the heat demand.
The temperature monitor "TW"
(target temperature 80 to 85°C)
monitors the internal temperature
of the unit.
After switching off the units via
the operating switch or the room
thermostats the supply air fan
runs to cool the combustion
chamber with the heat exchanger
for a certain time and then
switches off automatically.
This process may be repeated
several times if necessary,
depending on the temperature
profile.
In simple ventilating mode the unit
can be used to recirculate the air
permanently.
Thermostatic control is not possible
in this case.
