Mobile warm-air heaters
Type K 160 eco

3. Equipment construction

A ventilator and chromium-titanium combustion chamber with a heat exchanger and
exhaust gas nozzle fitted in the housing. The oil burner is installed in the switch cabinet with its
control units within the casing and above the air suction unit. The nozzle unit with flash tube is
mounted on the horizontally disposed chamber. Since the flame reverses within the combustion
chamber, it has to be long and slender.
Capillary tube thermostats are installed in the device. The temperature regulator ensures that
heating times are short when heating up by delayed switching on of the ventilator. When
switching off, the temperature regulator allows the ventilator to run for some more time to
remove the remaining heat from the device. The combustion chamber is thus protected from
overheating due to subsequent heat at the same time.
Efficient oil pre-heating has been installed in the devices for operation during cold external
temperatures. They heated a certain amount of fuel oil to the extent that the oil pipelines will be
supplied to the drum filter with warm oil and can start the burner so that trouble-free even at
sub-zero temperatures.
The room thermostat connection permits room temperature dependent control of the device
using a room thermostat.

4. Mode of operation

During operation, the heating oil EL is sucked in by the combustion pump through the suction
pipe from the supplied tank or from a firmly installed oil supply unit. The amount of oil required
for the heating performance is introduced into the burner nozzle through the pressure pipe,
sprayed into the combustion chamber and ignited. A flame lights up, which, together with its
combustion gases, heats the combustion chamber and the heat exchanger. Excess heating oil
conveyed from the pump flows back into the container.
The ECO 2-stage burner automatically starts in the first stage and thus ensures a smooth start
of the burner. After a few seconds, the burner turns smoothly into the second stage and then
generates the full burner output. The heat demand in the operation should fall, the device
automatically reduces the burner output and thus provides for a reduction in fuel consumption
50-10% compared to a 1step burner.
Another advantage of this technique is to reduce the burner starts the operation of up to 30%.
This leads to a reduction of ignition and controls and reduces the pollution of the burner head. In
addition, the K 160 eco is very low on emissions.
After a short heating up time, the temperature regulator switches on the ventilator. A very short
heating up time is achieved in this way. The ventilator blows the sucked in air through the
combustion chamber and the heat exchanger. It is heated up in this way. The heated up air
exits on the opposite side through the blow-out nozzle.
The main switch is switched on to position -II- "heating" for heating up. First, the burner starts
up and after heating up the combustion chamber and heat exchanger, the ventilator is also
switched on and conveys hot air.
A room thermostat that is possibly attached later on has to be set higher than the ambient
temperature, otherwise the device will not start up, since there will be no electricity supply.
The main switch is switched on to position –I- "ventilate" on the switch cabinet for ventilation.
Only the ventilator is running now. The device is now functioning as
a ventilation device.
The main switch is set to position -0- to switch off the device.
