What is a Spray Foam Rig and its Purpose?
Spray foam insulation is all the rage these days. It has started to surpass materials like fiberglass, which is why everyone wants a spray foam rig. They are compatible with both small and large scale operations.
What is a Spray Foam Rig?
A spray foam rig is often described as a complete but mobile job site. That description isn’t an exaggeration. A rig has every tool a polyurethane foam insulation contractor needs to do their work. That includes a generator and a spray foam machine. Depending on the model, a rig might also feature a work area with additional tools such as compressors and pumps. Rigs are portable, so you can carry them from one job location to another.
Types of Spray foam Rigs
Rigs can be categorized using a variety of criteria. But in most cases, they are classified like this:
1). Towable Trailers
As the name suggests, towable rigs are towable. That is to say, you can attach them to a vehicle such as a pickup truck to pull them. You can find towable trailers in numerous sizes, designs, and price ranges. Towable trailers are perfect for large SPF operations.
2). Box Trucks
These rigs are designed with self-contained operations in mind. Because they have a greater storage capacity, you can carry more hardware and chemical materials to each job site.
Some rigs are very small, designed to hold flexible equipment that can perform a variety of tasks. They have gained quite a bit of popularity because of their small footprint.
Choosing a Spray Foam Rig
How do you differentiate between good and bad rigs? You cannot expect every rig you encounter to meet your needs. Some rigs are suited more for some people than others. This is why you have to take the following factors into account when selecting a spray foam rig for your situation:
Rigs are supposed to carry your spray foam insulation equipment. But SPF work isn’t the same. The tasks you have to perform with your spray foam equipment will vary depending on the demands made by each client.
As such, you have to match the rig to the type of work you intend to do. For instance, if you want to perform residential work, you should look for rigs with a minimum output of 5-8 PPM. Heavy-duty operations, on the other hand, require a hydraulic rig.
With smaller jobs, you can use an air purge rig. It has become commonplace in startups because it is compatible with smaller projects. An air purge rig is normally paired with a decent air compressor and it can do coating work if you secure a device with decent air pressure.
You can use solvent purge equipment to do coating work as well. It is designed to prevent materials from mixing. It will also keep the rig’s chamber free of excess material. A solvent purge rig doesn’t require as much pressure because it uses extremely potent solvents.
Mechanical purge rigs are highly reliable and you use them to perform large-scale operations. As you can see, rigs are available in various designs and formats, and you have to match the rig’s attributes to the work you want to do. You cannot use the same rig for both roofing and insulation.
If you have never done SPF work, take a moment to analyze and understand the job at hand and the cost of a spray foam rig. This is especially important for companies that have to prepare bids. Once you figure out what you want to do, it won’t take you long to identify a suitable rig.
Spray foam equipment uses special chemicals that have to remain within a particular temperature range in storage. Otherwise, they won’t work as required. For this reason, you have to consider each rig’s insulation before you make a purchase.
It has to be reliable enough to protect your equipment regardless of the weather. Some rigs have air conditioning systems that they use to maintain the temperature within the right range during the summer. If you are lucky, your rig will also offer a heater for the winter months.
You can find cheaper models that do not have the necessary insulation if you are willing to insulate them yourself. Focus on the walls, ceiling, and floor.
3). Trailer Height
Have you ever attempted to insert SPF transfer pumps into chemical barrels in a short trailer? It is not only difficult but potentially dangerous because the barrels have chemicals. You have to tip the barrels which is challenging.
This is why you are encouraged to consider the height of the rig before you buy it. It should be tall enough to simplify your work.
Getting the Most out of Your Rig
If you want to get the most out of your rig, you need to keep the following in mind:
1). Cleaning your Equipment
You have to keep your spray foam insulation equipment clean. Keeping your equipment clean can enhance its lifespan in the long run. It will also reduce the rate at which your equipment wears out.
2). Maintaining the Nozzle
The nozzle is a crucial component of your spray foam equipment. It is also susceptible to clogging, especially if you permit the spray foam material to remain in the tip. It will eventually form blockages. This is why you are encouraged to wash the nozzle whenever you use it.
The manufacturer typically provides instructions detailing the best way to clean their equipment. Follow them carefully to ensure that you wash the nozzle without doing any harm to your hardware.
3). Maintaining the Motor
SPF equipment relies heavily on a powerful motor that has to be serviced regularly to prevent it from wearing out. If you fail to service your motor, problems such as a drastic decrease in nozzle pressure will arise.
You can mitigate these risks by servicing the motor annually. You don’t have to do this yourself. Find a technician that understands your equipment and the purpose of insulation. Besides servicing the motor, they will also inspect every other aspect of your rig to ensure that all the components are operating optimally.
If they find problems, they will either carry out repairs or replace any worn, torn, and warped parts.
