Application The oval Access Tank Cover LKD manhole covers are used on tanks or containers where a closeable means of access to the interior of the vessel is required.
The particular cover has been designed taking into account today’s demands for manhole covers which are suitable for CIP cleaning processes and where access to the tank is only necessary for occasional inspection Working principle Open the cover by loosening the handle. For inspection purposes the cover can then be turned into the tank. If it is necessary to physically enter the tank, the cover can be removed at the double hinge or swung out of the tank, depending on the model. The seal is hygienically positioned and is not affected by positive or negative pressure in the tank.
