Crown Engineering H24-31 Spiralink Coupler 323613-751 the Armstrong 3045PAB equivalent provides

the Armstrong 3045PAB equivalent provides the 3400 RPM performance required to maintain the system temperature rise across the heat exchanger

High Nominal Capacity: Capable of managing up to 22 tons of heat transfer depending on the refrigerant type

vibration-resistant DIN-rail or panel mounting

Optimized Probe Placement: Specifically engineered to position low water cut-off probes correctly within the flow path for accurate sensing

Key Technical Benefits Reduced Standby Heat Loss: Minimizes convective cooling of the heat exchanger during off-cycles to maintain system temperature

Crown Engineering H24-31 Spiralink Coupler 323613-751 the Armstrong 3045PAB equivalent providesThe Crown Engineering H24 31 Spiralink Coupler is a heavy duty, one piece 1 2" x 1 2" connector engineered to replace traditional, failure prone multi spring "fly away" couplings in HVAC and industrial systems. Designed with a high durability single spring architecture, this spiralink flexible coupling acts as a universal joint, providing three dimensional flexibility that compensates for axial, angular, and parallel shaft misalignment. By eliminating
