SE300 Pressurisation Unit
The KGN Pillinger “E” Electronic range of Pressurisation Units is a self-contained, fully automatic solution designed to maintain the correct operating pressure in sealed heating and chilled water systems. PLC controlled and engineered for reliability, the SE300E provides accurate pressure management while supporting efficient and corrosion-free system operation.
Sealed systems benefit from the elimination of air contact with system water, significantly reducing the risk of corrosion and improving long-term system performance. The SE300E automatically introduces water into the system as required, maintaining the preset pressure without manual intervention and removing the need for large header tanks within roof spaces.
Advantages of a Sealed System
- Eliminates corrosion caused by air and water contact within the system
- Automatically maintains the correct system pressure
- Removes the requirement for large roof-mounted tanks
- Improves system efficiency and long-term reliability
Design & Construction
All units within the Electronic range incorporate bronze duty pumps, housed within a brushed 304 stainless steel cabinet. The SE300E is suitable for floor-standing or wall-mounted installation, offering flexibility to suit a variety of plant room layouts.
