Spray Foam Rigs & Proportioners

A proportioner is the single biggest capital decision you'll make as a spray foam contractor — it determines your daily output ceiling, your fuel and generator draw, and how many jobs you can realistically stack in a week. We carry new and inspected-refurbished rigs across every configuration a growing crew needs.

Trailer, Truck-Mounted & Slide-In: Picking a Configuration

An enclosed trailer rig is the default choice for most growing SPF operations — the proportioner, hose reels, generator, and chemical staging all live inside a weatherproof box that tows behind whatever truck you already own, and it can be resold or repowered independently of the tow vehicle. Truck-mounted rigs bolt the equipment directly into a box truck or flatbed, which sacrifices some flexibility but tightens up your footprint on tight residential jobsites and cuts hookup time between stops. Slide-in units are the leanest option — a compact proportioner and short hose package that drops into a pickup bed, well suited to smaller attic and rim-joist jobs or as a second rig for overflow capacity without the overhead of a second full trailer.

Output capacity matters as much as configuration. A rig rated for 15–20 lbs/minute keeps a two-person crew moving efficiently on residential jobs without excessive idle time between sets, while larger commercial-volume rigs pushing 25+ lbs/minute make sense once you're regularly bidding warehouse roofing or large commercial shells. Buying more output than your typical job size supports mostly adds fuel cost and maintenance complexity without a proportional revenue gain — match the rig to your actual job mix, not your five-year growth plan.

What We Check Before a Refurbished Rig Ships

Pump Ratio Test

Every proportioner is run through a live ratio test under load before it's listed as sale-ready — no rig ships on a pass-by-appearance basis.

Hose & Heater Inspection

Heated hose runs are pressure-tested and heater bands checked for even temperature across the full run length.

Generator Service

Onboard generators get a full service interval reset and load test before delivery, not just a visual check.

30-Day Mechanical Warranty

Every refurbished rig ships with a 30-day mechanical warranty covering the proportioner pump, drive motor, and heater system.

New vs. Refurbished: Making the Call

A new rig comes with full manufacturer warranty terms and zero unknown history, which matters most if the rig is going to be your only source of income from day one. A properly inspected refurbished rig can cut 30–40% off the entry price while still delivering years of reliable service — the tradeoff is that you're trusting our inspection process rather than a factory warranty for the first several months. Most growing contractors buy new for their primary rig and add a refurbished unit as a second or backup rig once cash flow supports it, which spreads capital risk without sacrificing uptime on your main revenue source.

Whichever route you choose, financing is available through our equipment financing program — most approved contractors preserve working capital rather than paying cash out of pocket, keeping funds available for chemical inventory and payroll during the ramp-up period after a rig purchase.

What to Check Before You Sign for Delivery

Whether the rig is new or refurbished, do a walk-through before signing for delivery rather than after the transport driver leaves. Check for visible transit damage on the trailer body and hose reels, confirm the generator starts and runs under a brief load test, and verify the proportioner powers on and reads correct pressure at idle. Catching a transit issue at the point of delivery is a straightforward freight claim; catching the same issue a week later on your first job is a much harder problem to resolve.

Keep the documentation that ships with the rig — inspection records for refurbished units, warranty paperwork for new ones, and the freight bill of lading — in one place from day one. If a warranty claim or a resale down the line ever comes up, having that paper trail intact saves real time and often real money.

Rig & Proportioner FAQs

Do you offer financing on rig purchases?+

Yes — most approved contractor accounts finance rig purchases rather than paying cash. See the financing page for eligibility and typical terms.

What's the difference between a proportioner and a gun?+

The proportioner meters and heats the A-side and B-side chemicals at a fixed ratio and pressure, then pumps them through heated hose to the spray gun, which is the handheld tool that mixes the two streams at the tip and atomizes them onto the substrate.

How long does a refurbished rig typically last?+

With regular maintenance, a well-inspected refurbished proportioner routinely runs another 3–5+ years of active daily use before major component replacement is needed, depending on duty cycle.

Can I trade in my current rig toward a new one?+

Trade-ins are evaluated case by case based on condition and configuration — reach out through the contact page with your rig's make, model, and hour count for an estimate.

What output size rig do I need for a two-person crew?+

Most full-time two-person residential crews are well served by a 15–20 lbs/minute rig. Larger commercial-volume operations pushing roofing and warehouse work typically move up to 25+ lbs/minute.
