How to Choose a Spray Foam Insulation Rig

By Kevin Malone

Choosing the right spray foam rig can make a big difference. So, how do you pick the best one for your business? Here are a few basic steps you can take to help you decide which spray foam rig is right for you.

How Will You Be Using Your Spray Foam Rig?

Choosing a spray foam insulation rig will depend on the types of jobs you take on. If you are a contractor working on large projects, you will want a heavy-duty industrial spray foam rig. A smaller unit will likely work just fine if you tend to do smaller or infrequent jobs.

An air-driven machine may be your most affordable choice if you are a residential contractor or home builder. You will likely want a spray foam rig with higher output for large residential or commercial projects, so a hydraulic machine may be a better investment. If you install spray foam roofing, you will want to consider a high-performance foam and coating rig.

Choosing the Configuration

You can buy pre-equipped rigs or customize your own, but you will want to get the right one for the job.

Mobile spray foam rigs also come in different configurations, including:

  • Towable spray foam trailers that can be pulled with a truck. These can be installed in new or used trailers.
  • Box trucks offer a self-contained option, typically with a larger storage capacity to transport larger amounts of chemicals for high-volume operations.
  • Small spray foam rigs are becoming increasingly popular. Compact units have a smaller footprint and can be used with flexible equipment for multiple functions.

Choosing the Generator Size

If you do not properly size your generator to your spray equipment, you might not have the power you need to get the job done, or you may risk damaging your equipment. You will want to make sure you right-size your generator.

To do so, you will want to:

  • List your system components and peak loads.
  • Total up the wattage requirement for all the components.
  • Determine the kilovolt amperes (kVA) by multiplying the total wattage by 1.25.
  • Select a generator that meets or exceeds the required kVA.

Think about ROI and Budget

As you consider making any equipment purchase for your business, you will want to think about the return on investment (ROI). Compare the cost of buying a spray foam rig and the revenue it can help produce for your business.

The ROI can help you establish your budget.

Buy or Finance?

Depending on your financial circumstances, you may want to buy outright or finance your purchase to spread payments out over time.

Consider New and Used Spray Foam Rigs

You will get a warranty when you buy new equipment, so you have peace of mind that your equipment will remain in tip-top shape. New spray foam insulation rigs will also have the latest features, such as remote functionality and advanced reporting. You will also have more choices when adding accessories or parts.

Many contractors choose to invest in a dependable used spray foam insulation rig rather than buy a new one. When you work with a high-quality equipment vendor such as Intech Equipment & Supply, used equipment can be a viable alternative. You can lower your upfront costs and get a rig that has been thoroughly tested.
