A polyurethane spray foam equipment for sale is a machine that mixes and sprays two-component polyurethane materials on site. Many contractors struggle with high material costs, slow application, and poor insulation quality. Manual application is uneven. It wastes material. It takes too long. A spray foam machine solves these problems. It sprays evenly. It creates seamless insulation. For building insulation, cold storage, and pipe coating, our polyurethane spray foam equipment helps you apply faster and waste less.
YG Machinery offers reliable polyurethane spray foam equipment for insulation and coating applications.
What Is Polyurethane Spray Foam Equipment?
A polyurethane spray foam machine is a high-pressure mixing system that combines two liquid components (A and B) at the spray gun. The mixture reacts instantly and expands into rigid foam. The foam bonds to surfaces and forms a seamless insulation layer.
Suitable for:
- Building exterior and interior wall insulation
- Cold storage and warehouse insulation
- Pipeline and tank coating
- Roof waterproofing and insulation
- Refrigerated trucks and containers
Advantages:
- Fast application – covers large areas quickly
- Seamless insulation – no gaps or joints
- Strong adhesion – bonds to most surfaces
- High thermal resistance – reduces energy costs
- Moisture resistant – prevents water damage

Main Structure of PU Foam Spray Machine
A polyurethane spray foam machine has several main parts:
Main unit – Houses the heating system, pumps, and control panel. Pressurizes and heats the materials.
Spray gun – Mixes the two components at the nozzle. Creates fine mist for even application.
Heated hoses – Transport materials from the unit to the gun. Keep materials at the right temperature.
Transfer pumps – Pull material from drums and feed into the machine.
Air compressor – Provides air pressure for pneumatic models. Required for atomization.
Control system – Regulates temperature, pressure, and flow rate.
Core Advantages of Polyurethane Spray Foam Equipment
Many contractors now prefer a polyurethane spray foam machine because it improves both application efficiency and insulation quality.
Faster Application: The machine sprays continuously without manual handling. Covers large areas quickly.
Better Insulation Quality: Seamless foam layer eliminates gaps and cold bridges. Reduces energy loss.
Lower Material Waste: Precise spray control reduces overspray and waste.
Cleaner Work Areas: Spray system keeps material contained. No messy manual application.
Reduced Labor Costs: One operator runs the machine. No crew needed for manual application.
Stronger Material Properties: High-pressure mixing ensures consistent foam density and cell structure.
Multi-Material Compatibility: Spray polyurethane and polyurea. One machine, multiple uses.
Polyurethane vs Polyurea – Which Material to Choose?
Polyurethane foam is used for thermal insulation, soundproofing, and sealing. It expands and fills gaps. Good for roofs, walls, cold storage, and pipelines.
Polyurea is used for waterproofing, corrosion protection, and wear resistance. It forms a tough, flexible coating. Good for bridges, tanks, truck beds, and marine applications.
Many contractors now choose both materials because they serve different purposes on the same project.
- Polyurethane for insulation: Roofs, walls, cold storage, refrigerated trucks, pipelines
- Polyurea for protection: Waterproofing, tank lining, bridge coating, industrial flooring
YG machines can spray both materials. Switch between materials with a simple adjustment.
Application of PU Spraying Machine
This polyurethane spray foam equipment works well in many jobs:
Building insulation – Spray exterior and interior walls. Seamless layer stops heat loss.
Cold storage – Insulate walls, floors, and ceilings. Maintain low temperatures efficiently.
Pipeline coating – Protect pipes from corrosion. Insulate for temperature control.
Roof waterproofing – Spray seamless waterproof layer. Stops leaks permanently.
Refrigerated trucks – Insulate truck bodies. Keep goods cold during transport.
Containers – Insulate shipping containers for temperature-sensitive cargo.
Tank coating – Protect storage tanks from corrosion and temperature variation.
Marine applications – Insulate and waterproof ship components.
Customer Case – Warehouse Insulation Project in Russia
A construction company in Siberia, Russia was insulating a large warehouse. Winter temperatures drop to -30°C. The warehouse needed consistent temperature control for stored goods. Traditional insulation materials were slow to install. They left gaps and cold spots. Labor costs were high.
The contractor bought a YG-H5600(T) polyurethane spray foam machine. The hydraulic drive works steadily in cold conditions. The heating system maintains material temperature even in freezing weather. Workers sprayed the foam directly onto the walls and roof. The foam expanded and filled every gap. The seamless layer stopped heat loss completely.
Results:
- Insulation completed in 5 days (traditional method took 3 weeks)
- Indoor temperature stabilized at +15°C
- Heating energy consumption reduced by 40%
- No gaps or cold spots in the insulation layer
The project manager said: “The YG spray foam machine worked perfectly in the cold. We finished the job fast. The warehouse is warm. Our energy bills dropped. We will use this machine on every insulation job from now on.”
FAQ
Q: Can the machine temperature be adjusted?
A: Yes. Temperature is preset but adjustable. Different regions may need different settings. Users can adjust as needed.
Q: How do I clean the machine?
A: Put the transfer pump into cleaning solvent (methylene chloride). Run the machine and spray solvent out. Then put the pump into white oil (10# industrial) and flush the solvent out. Store with white oil in the system.
Q: Can it be shipped by air?
A: Yes, but the machine is large. Requires a large aircraft. Shipping cost is very high. Sea freight is more economical.
Q: What air compressor is needed?
A: 7.5kW, output 0.9-1.0 m³/min, pressure 8KG. Works for both pneumatic and hydraulic models.
Q: What is the standard A/B ratio?
A: Standard ratio is 1:1. Variable ratio machines are available on request.
Q: What is the minimum working temperature?
A: The machine works below zero. Raw materials need pre-heating in cold weather.
Q: Can I change the machine color?
A: Yes. Custom colors are available. Additional cost applies.
Q: How many units fit in a container?
A: 40HQ container: about 39 units. 20GP container: about 18 units.
Q: Does the machine have storage tanks?
A: No. Transfer pumps pull material directly from drums. Drums are available locally. No need to transfer materials. This avoids cleaning issues and material waste.
Q: Why is there black oil when first spraying?
A: The machine is factory tested with hydraulic oil. Spray new material to flush it out. A few minutes of spraying will clear the system.
