Smedegaard has released its new WallPress Whisper range of pressurisation sets.

The WallPress Whisper has been designed to be whisper-quiet in operation, delivering a low noise level that the company said is unmatched by any other competitor model. 

Each wall-mounted Whisper is designed for use with Smedegaard Expansion vessels and suitable for low temperature hot water and chilled water systems. It provides a minimum system pressure requirement and comes complete with a digital microprocessor control module as standard, delivering system diagnostics, high and low pressure monitoring and volt-free contact for boiler/chiller interlock.

The launch range of WallPress units is comprised of three different quality compact, wall-mounted models. The Whisper Single is the lightest, most compact solution at 460mm x 220mm x 300mm, powered by a 20w motor and delivering a maximum cold fill pressure of up to 4 bar. 

The WallPress Mono is also of single pump operation, fitted with a 0.6kw motor and available in 3- and 6-bar versions, and the range is completed by the Whisper Duo – the same compact size as the Mono at 510mm x 220mm x 440mm, but offering the benefits of twin pump capability.

As with all Smedegaard pumping systems, the Whisper range is of robust construction with features such as a pump over-ride facility and control module error logging.
