OVERFILL, BUND & MULTILEVEL ALARMS
The environment agency claim that pollution from fuel and chemical spillage is one of their biggest problems.

GNW’s easy to install alarms are robust and economical and will prevent you from
adding to an ever expanding problem.

OVERFILL ALARMS These units provide warning of a possible overflow giving time for action to avoid potential pollution. BUND ALARM Should an amount of fluid get between the tank and the bund then this unit will emit a 90dB warning alarm. This unit can also be used as an underfill alarm.

A combination of the Overfill and Bund Is Available.

MULTILEVEL ALARM
This unit gives a constant indication of the fluid level in the tank.
The LED flashes when the fluid is down to approximately 10% of the tanks capacity.
A 90dB alarm provides warning of possible overflow when the level rises to a preset danger point.

PROBES
Probes can be ordered according to tank depth and can be supplied with cable as required.

TIGERLOOP
The tigerloop which is fitted close to a pressure jet burner and separates air from heating oil doing away with the need for a return pipe to the tank.

FIRE VALVES
Fire valves are needle valves with a spring loaded inner stem held open by a fusible plug, which melts in the event of fire making the valve close. Preventing fuel being fed into a fire originated elsewhere than in the heating appliance.

Fire valves are used on supply lines for heating-oil or kerosene burners to prevent oil or
kerosene from the storage tank or feeding a fire.

SIGHT GAUGES These gauges give a clear reading on the level of the contents of a tank. They have unbreakable sight tubes and can be supplied in lengths to suit any depth tank. A variety of models of sight gauges are available.

VENTACAP
The ventacap provides weatherproofing feature that when in place will afford the correct volume for venting .

A grill prevents the ingress of leaves and insects etc without affecting the venting proves.

SCREWED FILLER CAP & CHAIN This unit was designed with the same function as the metal caps which are widely used on oil tank fill pipes, but manufactured from plastic making them more economical than the metal caps The cap is supplied with a chain and fixing clip.

VENT COVER
Designed to push and lock on to nipple or bend. Doing the job its name suggests.

SLUDGE VALVE A robust purpose made unit for fitting to a tank socket. It features a non removable valve to facilitate draining sludge without the danger of losing the core. FOUR IN ONE LEVEL GAUGE This unit has been developed to suit the needs of the modern rotationally moulded plastic storage tanks but retains all the other design features appropriate to steel tanks. The Tankmaster has four components that are usually fitted separately, i.e. gate valve, level gauge, filter and fire valve are incorporated in one unit.
