Armstrong Fluid Technology introduces the Astro 2 Hot Water Recirculation (HWR) pumps. A hot water recirculation system can save a typical family more than 12,000 gallons of water per year by eliminating the waste of water that occurs when occupants open a hot water faucet and have to wait for hot water to reach the fixture.
Astro 2 HWR circulators are suitable for use in a three-pipe installation with a dedicated return. The Astro Express 2 System includes the innovative Astro Express LF Valve and is designed for use in a standard residential 2-pipe installation.
Key enhancements offered in the new version of Astro 2 circulators include:
-
• Larger, easier-to-service electrical enclosure includes an integrated timer assembly.
• Timer Accessory Kit that can be used to upgrade earlier version Astro 2 circulators.
• New Timer Accessory Kit that can be used to upgrade new generation Astro 2 circulators.
• Easier field assembly of timers reduces installation time.
• Five-year warranty.
Astro 2 HWR circulators are available in stainless steel and bronze versions, with either NPSM Union or ‘sweat’ connections.
