STEP Internal Toroidal Tank

Manufacturer: Meridyen Alternative Fuel Systems
Origin: Turkey

Product description

The Internal Toroidal Tank is installed in the wheelbase of the vehicle when retrofitting an LPG system. The Internal Toroidal Tank is fixed to the under-body of the vehicle with screws and a counter plate.

An approximately 50mm hole is cut into the under-body of the vehicle and filled with a plastic tube. The plastic tube or venting connector serves as a ventilation hole in the event of a gas leak, as well as an opening for supply and discharge pipes which are connected to the multivalve. The multivalve is built into the inner base at an installation angle of 30° or 37° in the opening of the toroidal internal tank.

After proper installation, the inner base of the toroidal internal tank is closed with an air- and gas-tight cover. This cover prevents the escape of gas fuel into the vehicle interior.

Multivalves for toroidal internal tanks are marked with the abbreviation “H.” or “h.” plus a 3-digit number in the product designation. The abbreviation “H” stands for height and the 3-digit number for the height of the toroidal internal tank in millimetres. The 30° ending sets the installation angle of the multivalve. Multivalves with an “H” for height and the 30 ° ending are intended for toroidal internal tanks.

All STEP Toroidal Internal Tanks are tested and certified according to the latest European safety and quality standards (ECE 67R-01).

All STEP LPG tanks are characterized by a particularly robust corrosion and scratch resistant coating. The weld seams are checked in the in-house quality inspection procedure by means of the radiographic inspection for welding defects and cracks.

Mounting instructions for LPG tanks according to ECE 67R-01

Each LPG tank must be fixed to the motor vehicle at permanent fixing points or be fixed by a container framework and tensioning straps.

When the vehicle is ready for operation, the LPG container shall not be less than 200 mm above the road surface. The LPG tank must be installed so that metallic contact occurs only at the permanent fixing points.
