Armstrong Fluid Technology recently announced two enhancements to its Astro wet-rotor circulators: a larger wiring box for easier access and faster wiring on 220, 225, 230, and 250 Series circulators and the use of Noryl impellers.
The larger 3-in.-by-4.25-in. box includes a threaded connection to accept commercially available ½-in. NPT electrical connectors directly.
Used in Armstrong E Series and S&H circulators, Noryl impellers are field-proven through years of experience in a variety of applications.
