PU Spray Foam Machines for On-site Insulation Projects

WanFu Insulation supplies polyurethane spray foam machines for building insulation, roof insulation, wall insulation, cold storage insulation, pipeline repair, pipe joint foaming, tank insulation, and industrial thermal insulation projects.

Product Overview


Explore our core polyurethane insulation solutions for industrial and project applications.

Polyurethane spray foam machines are designed for two-component PU foam spraying, foaming, filling, and insulation construction.

The equipment mixes component A and component B at a fixed ratio, heats the materials through the heating system, delivers them through heated hoses, and sprays them through a high-pressure spray gun to form rigid polyurethane foam on site.

WanFu polyurethane pipe shells can be supplied in two-piece, three-piece, or multi-segment structures according to pipe diameter and insulation thickness. The segmented structure helps improve installation accuracy, reduce gaps, and provide stable insulation around the pipe surface.

These machines are widely used in building energy-saving projects, cold storage construction, roof insulation, wall insulation, pipe insulation repair, tank insulation, and industrial thermal insulation applications.

Core Selection Points

1.Output Matching
Match kg/min capacity with wall, roof, tank, or pipeline
repair project size.
2.Voltage Confirmation
Confirm 220V, 380V, 230V, or 400V according to your
local power supply.
3.Hose Length
Choose 15-90m hose according to jobsite distance
and construction workflow.
4.Spare Parts Plan
Prepare wear parts such as nozzles, mixing chambers,
filters, hoses, and seal kits.
