Micro Grow Greenhouse Systems uses Stahlin Non-Metallic Enclosures to protect critical controls in a corrosive greenhouse environment.

THE CHALLENGE: Properly protect greenhouse controls from corrosion.

Micro Grow Greenhouse Systems, Inc., has been providing environmental computer controls for professional commercial growers and research greenhouses worldwide for more than 40 years. Through its network of global distributors, the company outfits both large and small businesses with off-the-shelf and custom systems to meet specific needs. 

The Micro Grow team is focused on building systems that last. At times, this can be difficult task, because the greenhouse environment is notorious for corrosion. Corrosion in the greenhouse is most often caused by water, increased high humidity, and the use of reverse osmosis systems.

The use of reverse osmosis systems in greenhouse fog systems has dramatically increased in the past 10 years because of its reputation for increasing overall plant production. Yet, at the same time, reverse osmosis systems have a downside. The water produced from the system eventually attacks everything made of metal in the greenhouse, such as stainless steel enclosures. Why? Because this water is attracted to the minerals in the metal. So, greenhouse managers must have a corrosion prevention plan in place. Non-metallic materials are often used to prevent corrosion in this environment. This is why Micro Grow uses non-metallic enclosures to protect the company’s controls.

When Mirco Grow first began building products 40 years ago, metal housings were used. However, the company found that metal housings needed to be replaced much sooner due to corrosion created in any greenhouse environment. Micro Grow‘s engineering team was eventually convinced by Glenn Adams, the local Rexel electrical distributor, to switch to non-metallic enclosures to help reduce the long-term cost of the system due. Micro Grow has used Stahlin Non-Metallic Enclosures ever since.  “I always use a picture of one of our Stahlin Enclosure’s next to a rusted out painted metal enclosure in my Power Point presentations.  Nothing speaks more volumes than a pic.”

“With the newly found medical Cannabis industry requiring controlled environment systems, the need for our type of product has sky rocketed lately”.

THE ANSWER TO THE CHALLENGE:  Stahlin Non-Metallic Enclosures DiamondShield®.

Micro Grow currently uses the DiamondShield® product line from Stahlin Non-Metallic Enclosures because it features a high-quality, cost-effective fiberglass material with a unique design concept. Every cubic inch of the DiamondShield® interior volume is available and completely protected. Furthermore, the "No Limits" Panel Management System™ of the product line allows any panel of any size to be mounted at any height or depth and hinged in any direction, even on the door. DiamondShield® meets or exceeds all applicable IEC, NEMA, UL and CSA rating to UL/NEMA 4X, IEC IP 66.

In addition, another value-added quality for Micro Grow is that all Stahlin enclosures include the most unique compounding formula available—SolarGuard®, a patented non-halogenated fiberglass system. SolarGuard® outperforms all other available SMC formulations by as much as 60 percent, in its ability to resist Ultra Violet (UV) damage and retain gloss and color. SolarGuard® meets a NFPA No. 101 Class A flame spread index. Fire retardancy meets UL 94 5V standards.

A KEY VALUE-ADD: Stahlin Non-Metallic Enclosures and a local Rexel distributor have provided Micro Grow with superior customer support for over 30 years.

“Personal attention does make a difference in my book. The team from Stahlin Non-Metallic Enclosures willingly makes regular visits to my company to keep up-to-date on our enclosure needs,” stated Tom Piini, President, Micro Grow Greenhouse Systems, Inc. “We have also benefited from our local Rexel Distributor maintaining stock of Stahlin enclosures for our company. This stocking option makes it very easy for us to quickly meet our customers' demands. Quick turnaround is essential for many of our clients---- as is keeping the greenhouse running 24/7 is very critical for their bottom line.

“From the very first enclosure ever shipped to us, the associates at Stahlin and Rexel have always gone out of their way to solve problems and meet my needs, especially as we added new product lines, such as Weather Master and Weatherstat. Both systems protect greenhouses from high winds and rain damage, along with our brand new power back up system,” Tom Piini continued: “Micro Grow could not have existed for over 40 years without value add partners like Stahlin and Rexel.”

Campbell Scientific selects Stahlin Non-Metallic Enclosures for high-quality enclosures that perform well in extreme environments.


Since 1974, Campbell Scientific has been a leading designer and manufacturer of dataloggers, data acquisition systems, and measurement and control products. These tools are used worldwide in a variety of applications related to weather, water, energy, structures, machines, and soils. Campbell Scientific specializes in rugged, low-power systems for long-term, stand-alone monitoring and control.
Campbell Scientific has always been committed to producing accurate and dependable instruments. Although enclosures are often specified as an afterthought, Campbell Scientific knows the importance of the enclosure to protect instruments—if the enclosure fails so will the entire system.


Campbell Scientific uses non-metallic enclosures because they withstand a wide range of temperatures and other environmental factors unlike certain metals counterparts especially at high altitudes and corrosive coastal regions. Plus, metal enclosures tend to be heavier and more difficult to transport to remote locations to meet some of Campbell Scientific customers' needs.

Campbell Scientific's previous non-metallic enclosure supplier started to have quality issues in the field (UV fiberglass blooming too early) and was unwilling to accommodate some of the company’s special needs for enclosures without an increase in cost. In 2008, Campbell Scientific’s enclosure team started looking for a new supplier. They ended up making the decision to switch to Stahlin Non-Metallic Enclosures.


One of the reasons that Stahlin Non-Metallic Enclosures was selected by Campbell Scientific as their main supplier is because of SolarGuard®-- which is a unique proprietary non-metallic enclosures material formulation that is proven to beat competitors in harsh environments. This allows for better UV protection and reduces/delays fiberglass blooming. In addition, Stahlin was able to provide an enclosure in the color white which helps to aid in the reduction of high field temperatures.

The Stahlin management team was also willing to adjust shipping procedures over the years to ensure safekeeping in a Campbell Scientific warehouse setting. In addition, Stahlin negotiated a fair price so Campbell Scientific would be able to provide customers with the highest quality enclosures at reduced cost.

Stahlin Non-Metallic material formulation SolarGuard® :
SolarGuard® is a patented, non-halogenated fiberglass system that beats the effects of outdoor exposure and provides outstanding chemical and flame resistance. For guaranteed protection, SolarGuard® meets an NFPA No.101 Class A flame spread index, and UL94-5V standards for fire retardancy, which is achieved through the use of alumina trihydrate fillers. These are important aspects of enclosure protection, especially in remote, outdoor installations such as those where Campbell Scientific are installed.


Since 2008, Campbell has used Stahlin Non-Metallic Enclosures' popular J Series on their company’s instruments.


Because Campbell Scientific is confident that the enclosures will continue to perform, as promised, for customers in very harsh environments such as deserts, mountains, rainy/humid settings, and much more. Plus, the Stahlin team continues to successfully support the company with special enclosures requirements and has proven that they are willing to listen to any, and all, new requests.

Stahlin Non-Metallic Enclosures comply with the IK10 rating for external mechanical impact.
Photo Caption: The Stahlin N Series Non-Metallic Enclosure passes testing for IK10 rating for external mechanical impact.
Electrical enclosures are often put into harm's way in commercial and industrial environments. The enclosure must continually protect the controls inside, especially in environments such as warehouse or outdoor work areas where accidental damage due to collision with heavy machinery, equipment, vehicles and vandalism are often a daily occurrence.
How do you specify an enclosure that stands up to impact?
Look for the internationally recognized IK10 rating.

IK ratings are defined as IKXX, where "XX" is a number from 00 to 10, indicating the degree of protection provided by electrical enclosures against external mechanical impact. The higher the number providing a greater degree of protection with an IK10 being the highest rating available.
The ability of an enclosure to resist impact energy levels is measured in joules (J).
Stahlin Non-Metallic Enclosure IK Testing Results:
Stahlin Non-Metallic Enclosure had the following product lines tested and found compliant for IK:
  • J Series
  • DS Series
  • N Series Wallmount
  • N Series Control Tower

What is the main reason Stahlin Non-Metallic Enclosures stood up to IK testing?
Stahlin's patent material formulation
Every Stahlin Non-Metallic Enclosure is molded with a unique, patented sheet molding compound (SMC) formulation. This formulation is produced by Stahlin's in-house material processing system.

Stahlin J, CF, and F Series Non-Metallic Enclosures Pass UL 2043 Fire Test for Air Handling Spaces

On March 17, 2016, Stahlin Non-Metallic Enclosures provided the UL lab at the Northbrook testing facility with samples of the J, CF, and F Series. All three series were subjected to the same flame test described in UL Standard 2043, Fourth Edition.

Each of the Stahlin Non-Metallic enclosures product specimens tested MET all three requirements, which are:

-The peak rate of heat release measured during each enclosure tested was 100 kilowatts, or less

-The peak smoke release rate measured during each test was 0.21 m² /s, or less

-The total smoke released (10 minute test duration) was 75 m², or less

Photo Caption: The Stahlin F Series Non-Metallic Enclosure during testing for UL 2043.

The UL 2043 fire test simulates a rectangular volume of air space similar to an air handling space above an enclosed ceiling. The UL technician suspends the product approximately 24 inches above the live gas burner. The air intake occurs through a 12-inch tall opening located below the walls on all four sides. Exhaust heat and smoke rise into an air exhaust hood in which heat and smoke sensors reside. The flame conforms to a heat release rate of 60 kilowatts.
The test determines the rate of heat release and the rate of smoke release of the burning product samples as they relate to the requirements for fire-resistant and low-smoke producing characteristics in accordance with the provisions of the following codes: National Electric Code, NFPA 70; International Mechanical Code, NFPA 5000; and Standard for the Installation of Air Conditioning and Ventilating Systems, NFPA 90A.

Photo Caption: Stahlin Non-Metallic Enclosure CF Series during the UL 2043 testing.

How did Stahlin Non-Metallic Enclosures pass the UL 2043 test when so many other plastic product manufacturers struggle to meet the same requirements?

Fourteen ago Stahlin Non-Metallic Enclosures worked diligently with material suppliers to develop a unique patented Sheet Molding Compound (SMC) formulation and installed an entirely new material processing system. Together---these two investments have given Stahlin an advantage to provide high quality enclosures for environments such as the air handling space.

“Stahlin Non-Metallic in-house SMC formulation and compounding has always been one of our strengths. These new UL 2043 testing results for Stahlin’s J, CF, and F Series, provides even more evidence why our enclosures should be specified by engineers that need long term performance in the field,” stated Roger Schroder, Engineering Manager, Stahlin Non-Metallic Enclosures.

Since the 1940’s, Stahlin Non-Metallic Enclosures has engineered and manufactured innovative, reliable enclosures. Today, Stahlin is the leader and pioneer of fiberglass enclosures for outdoor and indoor industrial use. In addition, Stahlin offers one of the largest ranges of product sizes and enclosure options.

NS Wash selects Stahlin Non-Metallic Enclosures for price, quality product and unmatched support.

Photo Caption 1: NS Wash, the largest vehicle wash manufacturer on the West Coast---a control panel using Stahlin Non-Metallic Enclosures.

Designing and building superior equipment has been a tradition at NS Corporation since its inception in 1961, when founder G. Thomas Ennis recognized the need for more efficient and reliable vehicle wash systems. Located in Inglewood, California, NS Corporation is the largest vehicle wash manufacturer on the West Coast. It is an ISO 9001:2008 and UL certified company maintaining the highest levels of quality in the industry.

NS fabricates vehicle wash systems for trains, trucks, buses, car rental agencies, and conveyor car washes. The NS team has the expertise to build quality wash systems delivering a consistently clean, polished vehicle. The design simplicity of our systems deliver low maintenance and operating costs along with high customer satisfaction.

The Challenge:

Photo Caption 2: NS Wash has a UL certified panel shop in-house, where 100% of our control panels are designed and fabricated with Stahlin Enclosures.

To control these wash systems, NS has a UL certified panel shop in-house where 100% of our control panels are designed and fabricated. Before being introduced to Stahlin enclosures, our purchasing department was jumping from manufacturer to manufacturer in an attempt to beat the continual price hikes they were being hit with every time they tried to place a sizable order.

This constant changing of manufacturers caused frustration in our panel shop, and even more in engineering, where they were always trying to keep one step ahead of the ever-changing mounting configurations of the enclosures. An engineering directive was released stating there would be no more arbitrary changes of enclosures to try to reduce cost without first receiving engineering approval and revised drawings. NS Wash had lost any cost savings in the fire drill effort to rework equipment to accept these ever changing panels.

The Solution to the Challenge:

NS Wash put our suppliers on notice to find quality enclosures at a fair price. One came back with some Stahlin Non-Metallic enclosures samples, at a price point way under what we had been paying other manufacturers. After we made the decision to switch to Stahlin enclosures in 2014, we have stayed with them primarily not because of their lower prices but because of their unwavering customer support.
Patrick Doherty, Director of Engineering at NS Wash stated: “We discovered some issues with a number of panels at one point.  The following morning, Erik Faasen, Plant Manager at Stahlin flew to California to meet with us with a solution and recovery plan. I haven’t experienced that kind of support from a company in my 30 plus years in the work force. Thank you, Stahlin, for a quality enclosure and unmatched support.”
