HEIL Line is an industry standard. For over 70 years, HEIL Engineered Process Equipment has designed, fabricated, and tested fiberglass reinforced plastic (FRP) fans, scrubbers, and related equipment for application in process industries where corrosive fumes and gases must be cleaned and exhausted. The benchmark of HEIL products is workmanship, which with exceptional quality employs advanced engineering techniques and state-of-the-art testing procedures. These qualities are reflected in the high reliability and low-maintenance performance of HEIL Line products in tough, corrosive environments.
In continued efforts to supply the industry with the best available FRP equipment, HEIL has added a new series of fans and completely re-engineered existing lines to incorporate state-of-the-art technology and materials. The new series features a backward curved impeller that increases efficiencies by up to 20 percent.
Both the fan housing and the impellers of the HEIL Line centrifugal fans, in all series, are fabricated of solid FRP over male models.
A steel hub, with a taper-lock bushing assembly, is encapsulated within the impeller to ensure a reliable, secure connection to the fan shaft.
Fire-retardant polyester is the standard material for fabrication of any fan component that comes into contact with the air stream. It has excellent corrosion resistance to a wide range of chemicals. There are also several resin types, in a standard gray color, that customers may choose for specific applications. All of the materials HEIL uses meet requirements set by the Air Movement and Control Association for standard, Type A spark resistant construction (SRC).
Smooth interior surfaces minimize frictional losses within the fan inlet, wheel, and housing, as well as any build-up of solids.
Close tolerance fabrication and tight quality control assure peak performance and excellent corrosion resistance while keeping maintenance requirements low.
The in-process inspection during fabrication, assembly, and testing of each unit ensures that the highest quality standards are maintained. Each impeller is statically and dynamically balanced prior to assembly into the fan housing. The completed unit is then tested and reviewed for balance before shipment. Performance and sound level data are obtained from an independent testing firm, in accordance with the Standard Test Code for Air Moving Devices, published by the Air Movement and Control Association.
The fan shaft and bearing are designed to operate well below their critical speed. Bearings exceed the 100,000 hour life-rating specified in Standard B-10.
Fan bases are fabricated of heavy gauge steel coated with vinyl-phenolic paint. Other coatings are available to suit specific applications.
Arrangement 9 is the standard belt drive position. Arrangements 1, 4 and 8 are available for most series and fan sizes.
