Complete Protection Against Diesel Theft in Trucks, Heavy Machinery & Tractors

Lunoel Trading (Pty) Ltd was registered in 2007 and trades under the name of Innovative Technical Solutions with Diesel Guard being our flagship brand. The factory and head office are situated in Waterfall, near Hillcrest west of Durban in KwaZulu Natal.

The company was originally founded for the sole purpose of developing and marketing the Diesel Guard range of products to help combat the theft and pilferage of diesel from vehicle tanks.


The first Diesel Guards were originally designed by Hennie Lamprecht and his team in response to calls to come up with a solution to combat the theft of fuel from diesel truck tanks. Within a very short space of time the product proved to be a very effective barrier to protect fuel in the tank.

The range rapidly expanded to include all trucks, tractors and plant, construction and mining equipment common in South Africa.

With the price of diesel soaring in the mid 2000’s the transport sector needed an anti-theft/ anti-siphoning system that could withstand the robust African conditions and protect the bottom line.

The Diesel Guard range of products are exported worldwide and has established itself as a “World Leader” in fuel system protection and has represented this sector of the security market at a number of shows and seminars and expos.
