Niagara casing panels are heavy gauge steel utilizing double-brake design on all four
sides, welded in all corners providing rigidity, extended service life and durability.
Niagara construction employs nut and bolt fasteners. Drill-through hardware sustains
a much longer service life than metal screws. All metal fabrication is completed and inspected
at the factory before shipment to the job site.
Since Niagara engineers every system for the specific application, almost any materials
of construction can be specified. Niagara offers a variety of materials and tube sizes
for maximum performance and service life.
Commonly used tube materials include but are not limited to galvanized steel, stainless
steel, titanium, brass, and copper. Fiberglass structures and/or casing panels can also be
included in the design.
Standard Niagara unit components are Hot Dipped Galvanized After Fabrication according to
ASTM A-123. This zinc coating procedure provides 42% more resistance to rust and corrosion
versus mill galvanized steel.
Hot dipping insures that all surfaces and machined edges are well coated providing long
service life, even in harsh environments. Wet Surface Air Coolers can range in size
from smaller, packaged units to large, field-erected systems depending on the application.
Smaller units are factory assembled and shipped as one piece or split for multiple shipments.
These factory assembled units include structural skids, pumps, fans, and instrumentation. They
can be pre-piped and pre-wired to reduce field installation costs.
Field-erected structures can either be designed with concrete, FRP, or a combination of the
two. Niagara provides all civil engineering and plan specifications for concrete and component
installation.
