Polyurethane foam spraying machine

spraypneumatichydraulic

Product overview
Selecting the right PU foam spray machine directly affects construction costs and project quality. This product line includes pneumatic and hydraulic drive options designed for insulation, waterproofing and coating tasks in construction, cold storage, pipelines, roofs and exterior walls. Machines ensure controlled raw-material temperature and uniform chemical mixing to reduce waste and rework.

Applications

• Construction: exterior wall insulation, roof waterproofing, cold storage coating
• Transportation: soundproofing and corrosion protection for vehicles, ships and refrigerated trucks
• Manufacturing: pipeline corrosion control, tank insulation, equipment coating and filling projects

Key performance & features

• Pneumatic models rely on an air compressor: advantages include lower equipment complexity and good mobility. Typical heating power 9.5–15 KW; raw material flow 2–10 kg/min.
• Hydraulic models include an independent hydraulic station (no large air compressor required): higher output pressure and better handling of high-viscosity materials and cold environments; total/heating power up to 26/22 KW; raw material flow up to 12 kg/min.
• Heating systems (15–22 KW on some models) support winter/summer modes to maintain stable raw-material temperature and ensure uniform mixing.
• Multi-layer raw-material filtration (4-layer) reduces clogging; lightweight spray gun design decreases nozzle problems.
• Typical gas source requirements: 0.5–0.8 MPa with minimum airflow depending on model.

Operational notes

• Recommended air compressor for pneumatic models in construction: example 7.5 KW, 0.9 m3/min displacement, 8 bar to ensure stable operation.
• Pneumatic units support long pipeline lengths for standard projects; hydraulic units support extended pipelines for large-scale spraying.

Representative customer results

• Cold storage insulation: pneumatic model with 15 KW heating and suitable settings delivered ~30% reduced energy consumption and shorter application time.
• Pipeline corrosion protection: hydraulic model used for long sections; extended pipeline support and 4-layer filtration prevented clogging and improved coating durability.

Common Q&A (selected)

• How much raw material is needed for 1 cubic meter of foam? Total ≈40 kg (20 kg Material A + 20 kg Material B).
• Can it work in cold areas? Yes. Models with 15–22 KW heating and winter/summer modes warm materials quickly to maintain mixing quality.
• Typical price range Prices vary by configuration and power source; refer to product information for indicative market ranges.
