Smedegaard’s WallPress Whisper range of pressurisation sets are described as ‘whisper-quiet’ in operation. There are three models. One achieves a maximum cold-fill pressure of 4 bar. Another is available in 3 and 6 bar versions with a single or twin pump.
These pressurisation units are designed for use with Smedegaard expansion vessels and are suitable for LTHW and chilled-water systems. They come with a micro-processor control module as standard.
