Industrial Spotlight: Road Repair and Construction

When Vern Fiehler (of Quick Road Repair) needed to showcase his Instant Road Repair (IRR) product to the Juneau Alaskan International Airport, he encountered immediate problems. In order to demonstrate his product, he needed to bring the IRR up to working temperature. He attempted to use a forced-air ceramic heater to warm his materials and equipment, and unfortunately the outcome was catastrophic. The ceramic heater overheated his IRR product by 40°F / 22°C—causing it to perform horribly. In the end, it cost Vern a pallet of valuable road repair product.

Because of this learning experience, Vern now uses Powerblanket Bulk Material Warmers. Our Hot Boxes safely and evenly heat his products for demonstrations and he no longer has any problems with overheating or poor product performance.

Hot Box Features

Our world class team of engineers have infused our Hot Box Heaters with a long line of beneficial features.

Even Heat Distribution

As the road repair case demonstrates, not all heating products are created equal. Unfortunately, because of desperation, some turn to heating methods that offer little to no thermostatic control. Overheating can cause combustion, scorching, smoking, and as a result, create a dangerous working environment.

Powerblanket’s patented blankets offer even heating over the entire surface. This even distribution eliminates hot and cold spots and protects your materials and equipment without overheating.

Improve Viscosity and Flow

Fluid storage during winter conditions can be very difficult. Fluids can freeze outright, or become too viscous to even be usable. Applied heat lowers a fluid’s viscosity levels so it can be poured, drained, pumped, spread, and used during cold temperatures. Powerblanket Hot Box heaters efficiently solve viscosity issues and keep your operation running all winter long.

Protect Critical Materials

Applying heat to temperature sensitive chemicals and gases requires precision and care. Hot spots and sudden changes in temperature create dangerous storage environments. Our Pro Bulk Material Warmers give you direct control over your temperature ranges and heating schedules. This feature allows you to heat sensitive materials gradually so you avoid flash points, smoke points, and boiling points.

They also come equipped with a rugged, weather resistant, vinyl shell that reduces heat loss and protects your sensitive materials and equipment from the elements.

Easy Installation

When temperatures plummet unexpectedly or mother nature throws a brutal winter storm your way, the last thing you need is a finicky, time consuming heating product that is more trouble than it is worth.

When cold weather catches you off guard, Powerblanket has a fast and efficient heating solution for you. Our Hot Boxes are simple to set up quickly, get running, and take down. The compact storing size also makes it easy to store them and reassemble for future use. Our Bulk Material Warmers can be used on-site or even during transportation. Their convenient portability means you can take your heating solution on the road…literally!

All in all, we pride ourselves in offering safe, high quality heating solutions that get you back to work. For that reason, all of our patented heating products are certified to UL, CSA, and CE standards.

How Our Products Work

Our heating blankets save you time, energy, and money by putting the heat precisely where it is needed. After a simple installation, you are now harnessing the power of conduction and heating your materials with direct and even heat. Our advanced weather-proof insulation provides a protective barrier from the elements and reduces heat loss. We then combine insulation with efficient heating elements to direct heat downward right into the item that needs heating instead of losing it to the ambient air.

Powerblanket Product Families

Barrel and Bucket Heaters

Protect your fluid storage during the winter with a wide range of drum, barrel, and bucket heaters.  Direct, evenly distributed heat eliminates hot and colds spots, solves viscosity issues, and prevent your fluids from freezing. We also provide a range of specially calibrated blankets for coconut oil, honey, and wax. These blankets are programmed to stay within the exact temperatures these specific fluids need.

Tote and DEF Tote Heaters

For larger volume industrial fluids, these specially designed tote heating blankets are perfectly sized and shaped for steel, poly, and DEF totes. Our tote heaters protect the chemical composition of your fluids while still giving you pump access during winter conditions.

Gas Cylinder Heaters

When gas tanks drop in temperature, the pressure of their contents drops as well. As a result, it very difficult to get any gas flow from a tank during the winter. Gas cylinder warmers evenly and safely heat the cylinder so that flow rate increases and operations can continue running.

Bulk Material Heaters

How do you heat multiple containers of all shapes and sizes, or bulky pallets of materials? Hot box bulk material warmers provide even heating to anything stored within.

Ground Thawing Blankets

Frozen ground can bring a number of industries to a full halt during the winter. During sub-freezing temperatures, our high powered ground thaw blankets direct heat deep into the frost line to prep ground for digging, utility work, concrete pouring, and more.

Concrete Curing Blankets

Winter concreting is notoriously difficult. Construction heating can have a huge impact on jobs, deadlines, and the overall bottomline. From roofing, to spray foam, painting, and concrete, so many aspects are affected by the weather. Curing problems can derail entire construction projects and cause costly delays. Our concrete curing blankets provide heat, insulation, and cure concrete 2.8x faster than conventional insulation blankets. Electric concrete blankets are hands down the most efficient solution for strong and fast winter concrete curing.

Snow Melting Safety Mats

Free your hands and your time during the winter by setting your snow shovel aside. Simply lay down our Summerstep snow and ice melting mats on your doorway, stairs, and walkways. In addition, Summerstep mats provide traction and reduce injuries from slips and falls all winter long.

Smart Controllers

For an added level of control and automation, our Beacon Smart Controllers put temperature control at your fingertips. With the user friendly app, you have access to continuous remote temperature monitoring. You can also set heating schedules and receive temperature alerts right from your phone or tablet.

Industrial Cooling from North Slope Chillers

Our North Slope Chillers line represents the flip-side of our total temperature control expertise. Our industrial chillers, Fluxwrap fluid channel blankets, Keg Coolers, and Ice Wraps provide the perfect cooling solutions for when the heat is high.

Total Temperature Control

When your business feels the sting of wasted revenue through equipment damage, product loss, or the financial crunch of the “off season” due to unworkable climate conditions, Powerblanket has the solution. With Powerblanket, there is no “off season.” Contact us to find the perfect temperature control solutions to keep your work flowing at 855.993.6294 or [email protected].
