Halcyon Assembly™ Vortex Inhibitors & Plates

Halcyon Assembly™ vortex inhibitors, plates, & elbows; we also fabricate nozzles.


Halcyon Assembly™ vortex inhibitor units & plates are installed onto the suction line of fire pumps within a fire tank to control the turbulence in the flowing water. The National Fire Protection Association (NFPA) considers the Halcyon Assembly™ a Standard ancillary for every fire tank whether it is concrete, welded steel, bolted steel, fiberglass, or HDPE. They are engineered and manufactured with proprietary information from Climate Incorporated under our Climate Tanks™ international brand. They are very effective in controlling the velocity of the fluid thus preventing cavitation to fire pumps, damaging impellers, and collapsing municipal and residential water lines and tanks.

Our Halcyon Assembly™ product line expands from PE-100 to stainless steel that includes bolt on Halcyon Assembly™ plates, plate and elbow separately, and welded one-piece units. Over the past several years through our global network of partners, we have made plates and units from two-inch pipe diameter in multiple variations up to sixty-inch pipe diameter, which included manufacturing the plate in several bolt together pieces in order to make shipping globally an option for our clients.
