Spray foam application is a labour-intensive process that takes significant resources: time, materials, and equipment. Finding ways to improve jobsite efficiency is always a priority for spray foam technicians and business owners. One of the most common questions that crosses these professionals' minds is, “Can I use two spray foam guns on one machine?”
Here, we’ll explore the benefits of dual gun spray foam equipment, how it works, the additional equipment you need to make it possible, and why you’ll need a PMC Mach-2 — the only dual gun spray foam machine on the market.
Why Do Contractors Consider Using a Two-Gun Setup?
Efficiency is the number one priority of any spray foam contractor in Canada. The faster you can complete each project, the more money you can make. This is the primary reason why contractors consider upgrading to a two-gun setup. With multiple spray guns working at the same time on one machine, much more can be accomplished. Three specific reasons include:
1. More Productivity
Two people spraying at the same time cuts the amount of time a project takes in half. This increases overall spray foam productivity, allowing you to take on more jobs for your business.
2. Less Downtime
By achieving the same amount of spray foam coverage with one machine that you previously needed two for, you have less downtime. You only have to change materials once.
3. Higher Profitability
The faster you finish jobs, the more time you have to take on others. This directly translates to higher profits and a better return on your time.
Use case example: Imagine you’re responsible for insulating an entire large warehouse building. It’s time-consuming to transport multiple proportioners and spray foam machines, and if you don’t have multiple machines, you’re forced to work more slowly. A dual-gun machine speeds up your job twofold.
Exploring the PMC Mach-2 Dual-Gun Machine
The Mach-2 by Polyurethane Machinery Corporation is the only true, dual-gun spray foam machine on the market. PMC spray foam equipment is the gold standard in the spray foam industry and consistently outperforms and outlasts competitors.
Their patent-pending technology allows operators to safely use two spray guns with one proportioner. Some of the key features of their equipment and the benefits that they provide are outlined in the chart below:
| Feature | Benefit |
|---|---|
| Dual-Gun Proportioner | The only proportioner that can safely process plural-component materials for two spray guns. Produces an insulation spray foam large volume of up to 18 kg/minute. Can be used with anyspray guns utilizing up to an 02 chamber. |
| Ultrasonic Flow Meters | Monitors and maintains the spray ratios of both guns to ensure a high-quality application. |
| Independent Controls | Each spray gun on the proportioner can be individually controlled for both temperature and pressure. |
| Chemical Management Displays | A visual display shows important ratio, temperature, and pressure readings so that technicians can stay informed. |
| Reporting Software | All data is logged and graphed so that the performance of the spray foam machine can be analyzed, both in real-time and post-job. |
How a Polyurethane Spray Foam Machine Dual Gun Setup Works
It all begins with the plural-component materials A and B materials which are kept in separate drums outside of the machine. They are simultaneously pumped into the proportioner via the transfer pumps. This pumping is synchronized so that the exact same amount of material is transported to the spray guns, ensuring the correct consistency.
Once in the proportioner, the materials are heated and pressurized. Once pressurized, they travel through heated hoses (to maintain the temperature) to the guns via a dual-manifold system. Each side of the proportioner controls individual temperature and pressure.
When the two materials reach the gun, they mix for the first time. The high pressure of the system causes the materials to atomize and expand, allowing them to be sprayed. Once applied, the mixed material turns into a foam that’s 20-40x its original size.
Equipment You Need for a Dual-Gun System
Dual-gun spray foam system setup is quite complex. To make it all work, a variety of components are needed. These include:
- Heated Hoses: Heated hoses maintain the temperature of the mixed components as they travel to the spray gun.
- Transfer Pumps: Transfer pumps remove the A and B materials from their respective Drums and transport them to the proportioner. Each pump is synchronized to ensure that the A and B components are mixed in a 1:1 ratio.
- Spray Guns: You’ll need compatible spray guns for your dual-gun machine. The PMC Mach-2 works with chamber size up to an 02. .
Note: It’s important that your power supply can match the power demand of a dual-gun setup.
Benefits of a Spray Foam Machine with Two Guns
There are countless benefits of having a two-gun system, both from an economical standpoint and an efficiency one. As discussed, having two technicians on one machine allows you to complete jobs faster. You’ll also have fewer maintenance costs by only using one machine.
Another advantage of a dual-gun system is that it allows another individual to be trained without sacrificing an entire machine to them. You can have an experienced technician walk a novice technician through the process while still getting the job finished in a reasonable amount of time.
Challenges of Two Guns One Machine Spray Foam Applications
With all of those benefits being said, there are still a few challenges that come with a dual-gun system. The proportioner can be overloaded more easily, so it’s important to use the correct-sized gun. It’s even more important in a system like this that you’re comfortable controlling the ratio pressure of spray foam equipment.
Tips for Achieving Superior Spray Foam Application Efficiency
There are a few key spray foam job-site best practices that you can follow to achieve the highest efficiency and quality from your spray foam proportioner dual gun setup.
First, always collaborate and communicate with the other spray foam technicians. By working in sync, you can tackle the job efficiently and not get in each other’s way. By starting on opposite ends and meeting up, you can keep a good pace.
Secondly, stick to a regular maintenance schedule. Perform temperature and pressure checks and recalibrate as needed. Finally, always test your spray gun on a surface that’s not the final spray medium. This ensures that your system is ready to operate for the job at hand.
When Not to Use a Dual-Gun Setup
A dual-gun system isn’t right for everyone, and there are some situations where it won’t make sense. While the PMC Mach-2 can be used in all types of applications, a few criteria have to be met.
For obvious reasons, you want to be more than just a one-man operation. There’s no point buying a multi-gun system if there’s only one operator. You also want to make sure that you have a generator that’s high-powered enough to handle the additional power load of a dual-gun system. Similarly, the compressor needs to be equally compatible. If you don’t have these requirements in place, you may want to stick with a single gun proportioner.
Final Thoughts: Is a Dual-Gun Setup Right for You?
In summary, a spray foam machine with two guns is a great way to improve the efficiency, productivity, and profitability of your spray foam insulation business. However, there are still some challenges that should be considered, and a dual-gun system is not always right for everyone.
