Ventilator motor, ventilator fan and oil pump are the next assembly. (page 7, P. 22, 20 and 24).
A solenoid valve controls the oil supply of the burner thermostatically.
Normally a two step pump with integrated solenoid valves is installed.
The combustion chamber is formed by an extremely heat resistant tube reaching deeply into the flame area. This prevents
the still cold heating coil being sprayed by unburned oil during the start period, thus reducing distortion of the heating coil.
The insulation plate (page 8, P. 34) made from oxide ceramic prevents the combustion chamber from burning out.
It absorbs unburned sprayed heating oil as well as condensation water. During operation of the burner it will evaporate
immediately. The insulating plate will not be damaged by these procedures.
The safety device consists of:
Switch box with switch elements (P. 7, Pos. 19 + S. 16), Temperature limiting safety device (P. 7, Pos. 5 + P.13, Pos.10)
Flame control (P. 10, Pos. 18), Digital thermostat (P. 10 Pos. 20), Safety valve (P. 7 Pos. 30),
Flow switch (P. 7 Pos. 29) and manometric switch (P. 7 Pos. 31).
These safety devices guarantee the safe operation of the burner and regulate the desired water temperature.
The ignition transformer
(P. 7, Pos. 18) with 20 mA secondary current ensures high ignition capacity and thus a safe
start even under unfavourable conditions. It is mounted outside the switch box either on the outer casing or at the switch
box support to achieve better heat dissipation and moisture exclusion.
3. Definition and application
The BR series of burners have been designed to provide almost instant heating of water under pressure. The water may be
mixed with cleaning chemicals. However, in this case special attention has to be paid to the choice of material for the wetted
parts and if the chemicals are corrosive, a stainless steel coil material 1.4201 is recommended to be ordered.
The areas of application are primarily in cleaning applications for example:
Car washing in the automobile section,
Cleaning of façades (among others: removal of graffiti),
Floor cleaning (among others: removal of bubble gums),
Renovation of buildings and ships,
Cleaning of food production areas, abattoirs, sterilisation, etc.
4. Recommandations for installation
Mobile installation
Installation sites which are permanently under surveillance do not need a flame control. However, burners used in these
installations have to be provided with a permanent ignition spark. This applies particularly to mobile machines.
Stationary installation
Those installations which are not under permanent surveillance necessarily require a flame control.
Range of pressure
Low pressure range 4 – 20 bar
The normally fitted manometric/pressure switch has a shift point of 20 bar. For use in a low pressure range this switch is
not necessary and has either to be by-passed or to be removed. For low pressure use, the heating coil should be of 1/2“
tubing. Thus the production of steam bulbs which might lead to premature coil failure is avoided.
High pressure range 20 bar and above
Here mainly the 3/8“- heating coils are used, though the 1/2“- heating coils can be installed up to 200 bar depending
on the desired flow rates.
