Type CG

The Alfa Laval Type CG access tank covers are circular glass manway covers that provide a secure fit for openings of stainless steel tanks or containers used across a broad range of hygienic applications, including those in the wine, brewery, beverages, dairy and food industries. Designed to fit above the liquid level, they can be used as an inspection port or a closable means of access to the vessel interior for personnel. This makes visual and/or physical inspection easy, quick and convenient.

How it works

.

Construction

To enable visual inspection and/or safe access into and egress from the tank, the tank cover swings outwards. A pin prevents the lid from hitting the tank wall and safely keeps the lid open. The tank cover is positioned above the liquid level on top of the tank to meet application requirements.

Operating principle

To inspect or enter the vessel, open the round Type CG cover by loosening the handle. After exiting the vessel, close the manway cover by tightening the handle.
