The U.S. Department of Energy (DOE) has published a Federal Register notice of intent to establish a rulemaking working group to negotiate proposed federal energy efficiency standards for commercial/industrial pumps.
They serve two purposes: They regulate water flow to maintain the system’s high-side pressure and stop the flow of water when the system cycles off so as not to waste water.
For the first time, the U.S. Department of Energy (DOE) is considering creating minimum efficiency standards for clean-water commercial and industrial pumps — and they’re calling on industry leaders, manufacturers, industry associations, and other organizations for input.
The Coil-Connect™ manual and automatic balancing valves, combination ball valves, and unions and valve kits are available. Coil-Connect kits are provided with integral union connections and multiple tapped ports. Strainers and drain valves are also standard.
The NXT Series R-410A thermal expansion valves are balanced ported valves designed for high-efficiency R-410A air conditioning and heat pump applications. The valves operate over a wide range of conditions and applications, while offering excellent performance, reliability, and unparalleled valve life, says the company.
The Coil-Connect™ manual and automatic balancing valves, combination ball valves, unions, and valve kits, including balancing valves, combination ball valves, and unions are provided with integral union connections and multiple tapped ports. Strainers and drain valves are also standard.
Available in three sizes, with three speed settings per pump, the AquaPUMP™ hydronic circulating pump has a twist-to-fit flange which rotates 90 degrees to fit every application, the company said. The built-in hardened ceramic internal shaft and bearings offer high-corrosion resistance and longer performance.
