With Pressure Independent Technology, every system lives up to its full potential – saving time, money, and other precious resources.
It’s a fact. Efficient operation of variable flow systems cannot occur without effective flow balancing and control. Pressure fluctuations, system instability, and even minor design flaws will rob owners of efficiency throughout the life of the system.
There is a better way. Belimo pressure independent technology helps owners maximize the energy savings of variable fl ow pumping systems while addressing their unique control challenges.
Packaged into two product innovations – the PICCV and the ePIV – this technology has tamed costly flow control issues in thousands of installations throughout the world.
Pressure independent valves directly control the water flow required by the coil is not affected by pressure fluctuations in the system. The valves are selected based on the GPM requirements of the coil and no Cv calculations are needed. By precisely controlling the flow, the pressure independent valves eliminate the need for balancing valves, thus reducing the installation and balancing cost. By far, the biggest benefit for the owner comes in the form of energy savings by eliminating overflow thru the coil. Overflow wastes energy by over pumping and is the main cause of the low ΔT syndrome in chilled water systems.
Pressure independent control stabilizes control of variable flow systems for a lifetime of efficiency and worry-free, automatic balancing.
Everyone agrees that variable flow pumping systems have the potential to save facilities thousands of dollars in pumping energy. But all too often these savings quickly disappear due to complex flow issues.
With Belimo Pressure Independent Control technology only a single valve is required to maintain proper flow through each circuit. Each valve arrives from the factory pre-set for each circuit, so there is no additional balancing required. The system performs perfectly from start-up. And if a facility adds new circuits as a result of expansion, the flow control of existing circuits remains intact – so no rebalancing is required.
Pressure independent valves can be used to regulate flow through air handlers, heating and cooling coils, fan coil units, unit ventilators and VAV re-heat coils.
