While older circulator pumps utilized single-speed motors and were largely inefficient, advances in motor technology, controls, and pump design have transformed the market and ushered in a new era of highly efficient products that feature variable-speed motors, easy installation and setup, remote connectivity, and more.
Designed for use with hydronic radiators and steam boiler systems, HAV steam valves control the release of steam in radiators and properly balance the system so individual radiators produce heat appropriate for the space being addressed.
These booster pumps are available in 3-, 5-, 9-, 15-, 20-, 30-, 45-, 65-, and 95-cubic-meter-per-hour options with a flow range up to 600 gallons per minute (gpm) and 750 feet of total dynamic head (TDH).
From building automation systems, chillers, compressors, temperature control valves, and more, here’s a look at some of the equipment commercial contractors working in this sector may want to consider.
The SCV Weld In-Line Check Valve is used to accurately monitor direction of flow and pressure in liquid, suction, and hot gas lines. It’s designed for welding directly in-line via socket or butt weld end connections and is available for pipe connection sizes ¾-inch to 1 ¼-inch.
SCI close-coupled end suction pumps and SFI frame-mounted end suction pumps provide reliability and ease in installation for heating, air conditioning, pressure-boosting, cooling water transfer, and water-supply applications.
