Model 7300

Condenser-Filter Low-Pressure Dry Air

Features:

• Siemens PLC
• Profibus DP
• Circuit breaker
• Autodrain
• AC voltage-available lamp

Description:

Selected for the DDG 1000 class, the Model 7300 Mk I dehydrator is designed to remove water from low-pressure compressed air systems. The air delivered by this dehydrator is intended for use in control systems such as automatic combustion control, or in any low-pressure air system where it is desirable to eliminate moisture. The air delivered by this dehydrator is intended for general ship's service air.

Moisture removal is achieved by cooling the air stream with the ship's chilled water. The cooled air releases moisture by condensation. The condensate is mechanically separated from the air stream and drained to the LPAC’s trap-dump valve.
