Oil nozzles type LE are special versions
of standard nozzles type OD with built-in
cut-off valve. In combination with an oil
pump with LE-function (e.g. BFP 21 LE)
the LE nozzle prevents drop formation
when preheating and from oil expansion
in the nozzle line at burner stop.
Alternatively the LE-function can be
obtained by using a preheater with incorporated LE-valve (FPHB-LE) in combination with an OD-nozzle.

LE nozzles are available with 3 spray angles, 2
spray patterns and capacities from 0.40 to 2.0
Usgal/h. The nozzles are equipped with sintered
bronze filter.

Capacity 0.40-2.0 USgal/h:
30 μm sintered bronze
Note! The LE-function must be protected by an effective pre-filter
(max. 40 μm)
Oil Nozzles Type LE
The capacity and spray pattern is precisely the same as on an OD
nozzle. I.e. an 0.5 USgal/h, 60°S LE-nozzle is identical to an 0.5 USgal/h,
60°S OD-nozzle. The difference is that the pressure on the pump must
be increased by 1.6 bar in order to get the same capacity from an LE as
from an OD.
