This option has been primarily designed for domestic heating
applications where bottom offtake bunded tanks, in some cases, may
not be permitted.
Supplied as standard with the following:
Q A factory fitted 10mm brass compression fitting with internal
copper extractor tube. This fitting provides an offtake suitable for
most domestic fuel oil installations and provides enhanced
environmental protection by avoiding low-level penetration through
bund. A suitable pump to extract the tank contents and a non
return valve on the pipeline may be required. A hole should be
drilled in the top of the tank (see Figure 2) for the fuel supply pipe.
Check that there are no air leaks in the pipeline once assembled
Q 2” BSP (male) fill point with cap
Q 105mm diameter (4”) aperture with flush fitting cover
Q Lockable hinged manhole cover on outer tank
Agricultural applications
A top offtake bunded tank may be approved providing all
fittings and accessories are contained within the bund. We
cannot advise if this is practical to individual site
installations - however the standard 10mm compression
fitting and internal extraction tube provided for top empty
will be unsuitable for connecting to a standard type of
flexible fuel delivery hose and nozzle for dispensing diesel
(the tank components are removable for conversion
purposes). A suitable pump will be required to extract the
tank contents as this tank option does not provide the
assistance of gravity feed supply. Contact the Balmoral
Tanks sales office for information on the range and
suitability of pumps.
