Paratus Supply prides itself on building the highest quality turnkey spray foam rigs known to the industry. Our quality technicians will help you determine your spray foam equipment needs and support you every step of the way.

A spray foam rig is a manufactured trailer or box truck that is completely turnkey for the contractor. It allows for the spray foam contractor to show up at a jobsite, flip a couple switches and begin the application process. Turnkey spray foam rigs consist of a generator, compressor, air dryer, proportioning machine (Reactor), heated hose, transfer pumps and a spray gun.

A quality spray foam rig will be designed so that the weight distribution is balanced, allowing for a safe and smooth tow.  A well customized spray foam rig will usually included a good barrel bracing system to transport chemicals.  Tool boxes, cabinets and work bench will assist with storing tools and supplies in an organized manner.



A spray foam trailer or spray foam box truck should be heated and well insulated, using closed cell spray foam insulation. Safety equipment you may want to include in your rig: fresh air breathing, eye wash, first aid and fire extinguishers. Depending on the type of spray foam you will be processing, you may want to add on other tools such as mixers, cutters, a bung wrench and drum dolly.  These things have weight and need to be calculated when determining the correct spray foam trailer size and GVWR. If the spray foam rig is undersized and overweight, there will be many expensive issues.

To remove transfer pumps with ease, the height of the interior is extremely important. The strength of the spray foam trailer starts with the frame and is best to have a 2” x 6” steel main frame and not C channel. Axels are also extremely important; torsion axels are going to allow for a better tow and last longer. A narrow trailer is going to limit maneuverability inside the rig; we recommend an 8’ width.

Selecting the proper proportioner or (Reactor) is key. The proportioner (Reactor) will determine all the rest of the components needed to make sure that the spray foam rig runs smoothly during its life in production. Heater size of the proportioner and air compressor will determine the size of the generator or shore power requirements. The generator will determine the size of the spray foam trailer.



Doing it right the first time, perhaps at a higher cost, will save you money down the road. Do not cut corners to save a little money as fixing those problems that can arise later will cost far more than the initial savings. This will also have a lasting view of your company when you are not able to complete your jobs in the expected time.
