3.Steam Supply and Condensate Return Connections
The steam supply into the dryer is made into the
The maximum operating steam supply pressure is 150 psig (1,034 kPa).
The presence of condensate in the steam supply will cause water hammer and subsequent steam coil (battery) failure. The steam supply connection out of the main supply line must be made with a minimum
Use flexible couplings at the supply and return connections. The dryer vibrates slightly when it runs and the piping connections may crack if they are hard piped to the dryer. Install
An inverted bucket steam trap with an internal check valve is included with the dryer. The supply lines should be insulated. This will save energy and provide for the safety of the operator and maintenance personnel.
Water pockets in the supply line, caused by low points, will provide wet steam to the coil possibly causing steam coil damage. ALL horizontal runs of steam supply piping should be pitched
The condensate return line must be 1-1/4” pipe.
