A tank within a tank by CPV

THE latest challenge for tank designers at CPV, the preferred supplier of chemical storage tanks to JohnsonDiversey, saw the design, delivery and commissioning of a 20,000-litre polypropylene tank and two 7,000-litre tanks, fully fitted to specification.
The project called on JohnsonDiversey to supply a full hygiene package to one of Europe’s largest fruit juice manufacturers at a new site in the south west of England. And the 20,000-litre tank is the largest yet manufactured in polypropylene by CPV. Constructed as a ‘tank within a tank’, it holds caustic detergent for dosing to a cleaning-in-place (CIP) system for product pipelines, vessels, and filling machines.
The outer tank forms an integral bund around the inner and is equipped with a leak detection alarm system complete with pipework for liquid removal. All pipe connections are top mounted to minimise the chance of damage. Both inner and outer tanks are fully capped for full weather-proofing.
Manufactured from Black Leather grain polypropylene for use outdoors, the tanks were designed and built to BS EN 12573 (applying to welded thermoplastic storage tanks for corrosive liquids) backed up by in-house quality procedures in accordance with ISO 9002.
CPV supplied the tanks complete with control panels. All three are fitted with telemetry systems to allow remote monitoring of levels by the chemicals supplier.
