How much do your enclosures cost?

It depends greatly on the size, number of access panels and doors, and any other custom features. You can get an idea of Safe-T-Cover's prices for different sized enclosures by looking through our standard models. You can see the height, width, and length for more than 50 sizes there. If you know how large your enclosure will be, that is a great starting point. Here is an in depth post all about how much our enclosures cost.

Can you make enclosures to a specific size? How big can they get?

Safe-T-Cover can fabricate metal enclosures to fit your exact dimensions. Depending on the materials and how the manufacturer builds enclosures, you may have something custom fabricated, or they may use a modular design to accomplish this. Modular enclosures can help keep costs low because even though the full enclosure is custom, the panels that make it up are not. There would be fewer extra fabricating costs passed on from manufacturer to customer. You can learn how to size your custom enclosure in this short video.

How can I make the enclosure look nicer?

Safe-T-Cover's enclosures are available in several colors. All of our standard enclosure models come in four standard colors (slate grey, hartford green, sierra tan, and aluminum) with no additional cost. There are also numerous other color options that are available to choose from. Other options, depending on the use, is to wrap the enclosure like the one seen here to the right or to hide the enclosure with landscaping. Check out our page on aesthetics for help making your enclosure more attractive.

How long will it take to design the enclosure? What if I need it quickly?

Once you have contacted us for a quote, things should move pretty quickly. It only takes a few hours to produce a quote if you have a general idea of your design in mind already. Designs for enclosures that shelter equipment can generally be made available in about a day. If there are some revisions to the design along the way, that can lengthen the design process. Safe-T-Cover has a library of details so we can find a similar design and alter it to speed things up. Your enclosures typically should take no more than a month from the purchase order to delivery.

What kind of heat can you provide? How do your heaters work?

Safe-T-Cover offers a patented slab mounted heater designed and UL-2021 rated for wet/damp environments. To see how this thermostatically controlled slab mounted heater is superior to wall mounted heaters, take a look at this short video. Our enclosures, when the correct wattage of heating is installed, will maintain 40 degrees Fahrenheit inside the enclosure when the exterior temperature is as low as -30 degrees Fahrenheit as is required by ASSE 1060 Class 1. So even in the coldest environments, if you need to keep the equipment inside the enclosure from freezing, you’ll be able to do so with this heating option. We also offer a couple of alternate heating solutions. You can find the full list of our hot box heaters here.

What if the equipment generates heat or needs ventilation?

Often the equipment installed inside the industrial enclosure generates heat. In that case, Safe-T-Cover can install an exhaust fan and louver system. The exhaust fan is wired through a thermostat and when the temperature reaches the set point the fan will run and the louver will open to draw air through the enclosure. Reach out to us if you think you may need air conditioning in your enclosure as well.

Is it possible to remove equipment if it needs to be replaced?

Equipment wears out or breaks down and needs to be replaced.  Not a problem. Safe-T-Cover works to improve accessibility by designing enclosures with hinged double doors. That way a fork lift or pallet jack can be used to access and remove the equipment that is housed inside. If you need want to access and remove the equipment through the roof we can design a roof with panels that are easily removed. If the enclosure is small, the roof panels can be hinged for total access from above.

Why not install RPZ backflow preventers indoors instead of an enclosure?

Even the smallest RPZ can discharge a dangerous amount of water at system pressure. The way most engineers work around these dangers is to install a floor drain or floor sink. However, this is almost NEVER sufficient. Take the flow rate of the RPZ and the drain's capacity into consideration to find out how big of a drain is needed. Without having to look into the math, you can watch our video of one of these devices drumping water, you'll see that the drain will not easily carry all the water from this backflow preventer.

Why should backflow preventers be installed above ground?

Many vaults flood regularly. Repeatedly, water purveyors, cross connection control managers, and backflow testers tell us that flooded vaults are a completely normal occurence. Some even send in videos of draining these flooded vaults in order to test or repair the backflow inside. Flood water is obviously unsafe and a potential cross connection is created in a flooded vault whether the test cocks are opened or closed. For an in depth explanation of why you should keep backflow preventers out of utility vaults, read this post.
