Proven Protection for a New World of Renewable EnergiesStahlin Non-Metallic Enclosures

RIGHT PRODUCT:Stahlin Enclosures are the most specified

non-metallic electrical enclosures in the world.WHY?

Because of unsurpassed, proven product performance and quality.

Because we pioneered the original composite enclosurenearly 50 years ago.

Because we offer the largest available selection of in-stocknon-metallic enclosures that maintain a balance betweenappealing aesthetics and stringent physical property perform-ance standards including NEMA 4X and NEMA 6P integrity.

Because we offer diverse enclosure modification and customizing options through our ModRight® program

RIGHT PRICE:Stahlin is competitive from the word Go! for these

primary reasons:

We have hands-on control of our integrated, in-house manufacturing process from first step to last touch.

Non-metallic enclosures offer significant economic savingsover metallic alternatives such as stainless steel, yet providecomparable or superior physical property benefits.

We are price competitive with other non-metallic materialoptions while frequently offering better performance value.

The unique added value of our non-metallic enclosuresbrings you protection from the high cost of failure.

RIGHT NOW:Stahlin assures you of the fastest available turnaround from

immediate professional design assistance to on-time delivery.

Because we know you need durability in an enclosure ---we’ll warranty our product longevity for a full decade!

We can do this because Stahlin enclosures are rugged, reliablenon-metallic composites, not molded thermoplastics. Plus ---they defeat the damage from weathering and corrosion thatcause so many early product failures with metal enclosures.Composites also provide superior dimensional stability becauseof low coefficient of thermal expansion versus stainless steel.

2.) PROTECTION FROM CORROSION AND ENVIRONMENTAL DAMAGE.

Stahlin non-metallic enclosures provide superior corrosionand chemical resistance compared to metallics such as aluminum and painted or galvanized steel… and are very comparable to that of stainless steel. With non-metallics,enclosure maintenance is virtually eliminated.

3.) PROTECTION FROM UV-RADIATIONIn addition to proven protection from weathering and

environmental impact such as dust and moisture, Stahlinenclosures are molded from the most unique compounding formula available on the market --- SolarGuard®. Don’t befooled by cheap alternatives.

SolarGuard® is a patented non-halogenated fiberglasssystem that beats the effects of outdoor exposure plus provides outstanding chemical and flame resistance. SolarGuard® out-performs other available SMC formulations by as much as 60%

Six Best Reasons Why Stahlin Non-Metallic Enclosures Are Ideal For Meeting the Demands of Renewable Energies Applications:1.) DURABILITY.

You need durability and protection. Stahlin delivers enclosuresthat are built to last… and we’ll prove it with our:

in its ability to retain gloss and color after exposure to concen-trated UV light. SolarGuard® is also able to reduce the effects ofUV degradation such as surface roughening and fiber blooming.

SolarGuard® meets a NFPA No. 101 Class A flame spreadindex. Fire retardancy, achieved through use of alumina trihydratefillers, meets UL94-5V standards --- an important aspect ofenclosure protection, especially in remote installations.

SolarGuard® features new, proprietary double-protection formu-lation technology that significantly enhances the molecular bondstrength and crosslinking that occurs during the curing process in thermosetting polyester sheet molding compounds

SolarGuard® fights polymer degradation by making it muchmore difficult for UV light to attack molecular bonds of both primarychains and crosslinks. A special UV Absorber is added to theSolarGuard® formulation which acts to absorb UV energy, then to release it without damaging the polymer chain.

As the new standard SMC formulation for all fiberglass electricalproducts, Solar Protection provides an unsurpassed level of UVresistance, fire retardancy, chemical resistance and safe, durableperformance… all without adding cost to enclosures!

4.) DIVERSITY OF ENCLOSURE CHOICESStahlin provides the most extensive in-stock line of freestanding,

wallmount, indoor/outdoor, junction and other non-metallic enclosures and accessories available to meet all needs and standards required for applications within the renewable energiesmarket including:

• UL/cUL 50, Types 1, 3, 4X, 6P, 12 • UL File Number E64358 • CSA Std C22.2- File LR69014 Types 1, 3, 4X, 6P, 12 • NEMA Standard 250 - Types 1, 3, 4X, 6P, 12 • Temperature Range- (-76°F to +250°F) (-60°C to +120°C) • Flammability Rating- UL94-5V (#E81860) • IEC60529 • IP66 • IP66• Window flammability- UL94V-0

Additionally, we provide expert design and engineering guidancefor custom applications.

Stahlin Non-Metallic Enclosures are lightweight and easy tohandle compared to metal enclosures and are extremely easy to drill, punch and cut compared to all metals. Retrofitting is eliminated because of the ability to modify composites withknockout panels and windows.

Our ModRight™ Enclosure Modification CapabilitiesModRight™ offers customers the opportunity to benefit from

Stahlin’s inhouse capabilities for achieving accurate, cost-effectiveenclosure modifications. The program provides diverse choicesfor factory customizing of enclosures including cutouts, holes,windows, vents, countersinking, latches & locks, and nonstandardsizing.

ModRight™ also showcases Stahlin’s computer-controlled manufacturing systems, panel management expertise, custommolding options, and specialty areas such as EMI & RFI shielding.Through the ModRight™ program, Stahlin offers more than 20standard colors and the opportunity to computer match any custom supplied color sample. Graphic interfaces including silk-screening and decals are also available.

5.) COST EFFECTIVENESSStahlin non-metallic enclosures are significantly more cost

effective than stainless steel (20-40% less) and are very compet-itive with other metallics. We are highly competitive with othernon-metallic enclosures and our value-adds, such asSolarGuard®, put our enclosures in a performance class by them-selves without adding cost to our products.

6.) “MADE IN THE U.S.A.”MANUFACTURING LEADERSHIP

Nearly 50 years ago Stahlin Enclosures pioneered the world’sfirst fiberglass composite enclosure.

Since that time we have broadened our marketplace leadership.As the primary source producer of all our own enclosure components,we provide you assured quality control.

From a single manufacturing location located in Belding,Michigan, we:

• Formulate and blend our own fiberglass composite includingpatented SolarGuard® for unequaled UV resistance.

• Mold our enclosures using the highest processing standards.• Integrate CNC and other technologies to optimize bonding,

gasketing, customizing functions, and final assembly processes.• Maintain a balance between appealing aesthetics and stringent

physical property performance standards including NEMA 4Xand NEMA 6P integrity for completeness of protection ofinternal components from external elements.
