According to Smedegaard, the system is “whisper-quiet” in operation, with a noise level less than that of competitor models.
The Whisper range is designed to provide a minimum system pressure requirement. It incorporates a digital microprocessor Control Module which delivers system diagnostics, high and low pressure monitoring and volt-free contact for boiler/chiller interlock.
The Wallpress Whisper pumping system is designed for use with Smedegaard's Expansion vessels and is suitable for low temperature hot water (LTHW) and chilled water systems.
