PetroTechnik subsidiary Cookson and Zinn has been designing and fabricating CZ Tanks and pressure vessels for the last 45 years.

In that time, over 8000 tanks from 5000 to 100,000 litres have been supplied to 20 countries and trading relationships involving the transfer of design and fabrication technology have been established with companies in Central America and South Africa.

Protection of the environment has always been a number one consideration for CZ. Quality control is rigidly enforced and ISO 9001:2000 procedures ensure full traceability of materials and rigorous product testing. Deuma automatic tank assembly and welding equipment guarantee maximum concentricity and straightness.

CZ is a founder member of the double skin tank design committee and has developed a system ensuring 24-hour monitoring for potential leakage.

CZ has a wide range of products encompassing bunded storage systems, double skin underground storage tanks, above ground vertical and horizontal storage tanks, stainless steel tanks and vessels, liquid petroleum gas vessels, framed tanks and pressure vessels.

CZ tanks are used in many industries including fuel, chemical, food, pharmaceutical, agricultural, aviation, water and general manufacturing.

PetroFast – modular filling stations

PetroTechnik has developed a revolutionary modular filling station solution incorporating CZ tanks and UPP pipework. Each system is factory assembled meaning rapid on-site installation. Customers can specify the degree of pre-build to suit their needs from tank and tank mounted canopy support to a full pressure tested underground system with the canopy in place.
