Armstrong enhances its wet-rotor circulators

Armstrong Fluid Technology has announced two new enhancements to its Astro wet-rotor circulators.

These include a larger wiring box for easier access and faster wiring on the 220, 225, 230, and 250 Series circulators.

This larger 3” x 4.25” box includes a threaded connection to accept commercially available ½” NPT electrical connectors directly.

The identical wiring box is also used on larger capacity Astro models.

Armstrong has also upgraded its Astro Series circulators to use Noryl impellers, the same material used in Armstrong E Series and S&H circulators.

The Noryl impeller has been field-proven in a variety of applications.

All Astro circulators also include a 5-year warranty.
