mikrofill PRESSURISATION UNIT The WRAS approved Mikrofill 3 pressurisation unit incorporates • Fluid Risk Category 4 backflow prevention • The ability to fill directly from mains/ boosted water supply any LPHW or CHW system from empty • Comprehensive electronic pressure management The Mikrofill 3 contains no pumps or RPZ valves. 4

Unlike “pump type” pressurisation units the Mikrofill 3 is designed to be connected directly to a buildings incoming mains/boosted water supply and fill a heating or chilled water system without the use of a pump. The Mikrofill 3 is the most energy efficient unit of its kind consuming as little as 10 watts/hr on standby and 30 watts/hr fully operational. FEATURES BENEFITS • Integral fluid risk category 4 • No RPZ valve required backflow prevention • Connects directly to the mains/boosted • Fills any LPHW/CHW system water supply from empty • 2 methods of flood protection • Comprehensive electronic pressurisation manager • 97% more energy efficient than some pump type units • Consumes 10 watts on standby and 30 watts fully operational per hour • Compact enough to fit in the smallest of plantrooms • Wall mounted unit • Aids water treatment calculation • Fill volume indicator • No onsite commissioning required • Pre- commissioned packages available • Clear and concise instruction • Large colour screen display 5

WATER | A PRECIOUS RESOURCE The water regulations define fluid risk categories by the type of contaminants which are present and specify the appropriate type of prevention device which must be fitted to guard against backflow. Commercial heating and chilled water systems are defined as fluid risk category 4 and as such any device that is permanently connected to the wholesome water supply must provide at minimum, that level of protection. The Mikrofill 3 provides that level of protection. 11
