Abstract
The invention relates to a reciprocating grate cooler in which the drive arrangement is enclosed by a drive housing, the interior of which is closed off so as to be airtight against the atmosphere, but by contrast has a pressure equalization connection to the interior of the cooler housing. Such a reciprocating grate cooler is distinguished by a substantially reduced expenditure for the sealing of the cooler housing and a high degree of freedom from disruption.
