Covering all tank needs
Alfa Laval offers a complete range of high-quality manhole covers to meet virtually every requirement. More than 50 different types of oval, circular and rectangular covers are available. These securely fit the openings of pressure, non-pressure and low-pressure tanks, both above and below the liquid level. A wide variety of sizes with frame heights between 60 mm and 200 mm is available. Tank covers can be fitted with different sight glasses and relief valves.
For hygienic processes, there are two models from which to choose: the oval-shaped Alfa Laval LKD Tank cover and the circular Alfa Laval LKDC Tank cover in standard and pressure models for both above and below the liquid level.
