Tank equipment for oil heating technology

Filling and bleeding, filling level

Fittings for safe filling and bleeding, as well as for level detection.
Tank caps ensure a secure closure and connection of the filling hose to the filling pipe of the tank. Tank caps with bayonet according to EN 14420 part 6 (or part 8 for France) are recommended for a direct connection of the filling hose of the tank vehicle. Tank caps with screw connection provide a secure hold for adapter pieces.

Metal vent caps are particularly durable.

Fuel gauge locks as well as mechanical and pneumatic tank level indicators are available for determining the fill level.

Tank filling limiters

The switching amplifier of the tank truck in conjunction with the tank filling limiter prevents overfilling of the tank. The tank filling limiter is a “sensor for tanks with current interface as part of an overfill protection system of type B and design B1 according to EN 13616”. All tank filling limiters are TÜV tested and are marked with CE sign.

The 2 types differ in the connection fitting:
Type 21300 with fitting for pipe mounting (904), preferred for underground tanks according to e.g. DIN 6608, DIN 6616, DIN 6617, EN 12285-1, EN 12285-2, DIN 6624, DIN 6619, DIN 6623, and DIN 4119.

Type 21301 with fitting for wall mounting (905), cable length approx. 5 m, preferred for above ground tanks according to e.g. DIN 6620, DIN 6625, EN 12573 parts 1-3, EN 13341 parts 1-3, EN 13121 parts 1-3 and battery tanks with general type approval up to 25 single tanks.

A tank filling limiter of type 21301 is also included in the Flexo-Bloc item no. 2052351.
