Application
The Type C, Type O and Type R stainless steel
manhole covers are used on tanks or containers including bottling
and washing machines. The products are suited for a wide range of
sanitary applications such as wine, other beverages, dairy and
foodstuffs. They are designed to fit where a closeable mean of
access to the interior of the vessel, situated above or below the
liquid level, is required. To fit various requests the cover comes
in oval, circular and rectangular shape.
Working principle
Open the cover by loosening the handle. This range
includes covers with various openings. For inspection purposes there
are covers with inwards opening. If it is necessary to physically
enter the tank there are covers with outwards and/or side-swing
openings.
