Many of the best reasons to insist on Armstrong unit heaters are ones you never even see. Components like motors, bearings, tubes, enclosures and fins are heavy-duty, to ensure lasting performance.
Armstrong’s options for fin material, pitch, height and type, for example, help explain why our heating cores last much longer and perform with greater efficiency than competitive units. These factors all have a bearing on heat transfer. Knowing how to balance these and other factors is the key to a cost-effective solution. That knowledge is perhaps the most important of Armstrong’s many hidden benefits.
When it comes to long life under tough industrial conditions, Armstrong is all you need to know about unit heaters and door heaters. Even in the most severe environments, where coil leaks and corrosion are costly problems, Armstrong coils maintain high efficiency and output.
The ability to maintain heat transfer efficiency and resist corrosion—both internally and externally—is why Armstrong coils are uniquely dependable. How we construct them is your assurance of lasting performance, even in severe operating environments. Consider these measurable benefits at work in your facility:
Heavy-duty enclosures. Fabricated from 14-gauge steel for protection and durability.
Corrosion-resistant heating cores. Cores are fabricated in a full range of materials, including steel, stainless steel and copper. Special coatings may be applied to increase resistance to external corrosion. Cores are of all-welded construction for durability and ease of repair. Cores are compatible with steam or liquid, and they can be used for steam, hot water or glycol heating mediums.
Standard NEMA frame TEFC ball bearing motors. Supplied in all sizes, these heavy-duty motors are totally enclosed to lock out dirt. Quick access to the motor permits easy replacement.
Thick fins and tubes. The coils are constructed of high-strength, corrosion-resistant materials. The fins are available in a wide variety of thicknesses and pitches to withstand high-pressure cleaning without damage or distortion.
Customizing to your needs. Fans range in size from 10" to 48", and the wide selection of component material means long, trouble-free service life.
