Advantages of Tank insulation spraying

Flexible construction

Spraying machines can cover vertical tanks, horizontal tanks, and complex curved surfaces, with fast construction speed and reduced labor costs.

Long-term durability

Resistant to high and low temperatures and weathering, with stable long-term insulation performance and low maintenance costs.

High-efficiency insulation

High closed-cell ratio and low thermal conductivity effectively reduce heat loss and ensure stable temperature of the contents of the storage tank.

Energy-saving and environmentally friendly

One-time spraying completes the coating, eliminating the need for secondary insulation materials, reducing material waste and energy consumption.

Waterproof and corrosion-resistant:

The dense, seamless foam layer prevents rainwater penetration and corrosion, extending the service life of the storage tank.

Recommended thickness of tank insulation layer

Storage Tank Types	Contents temperature range	Recommended insulation thickness
Ambient Temperature Liquids (0~40℃)	Near room temperature	20–30 mm
Medium Temperature Liquids (40~80℃)	Low-temperature loss requirements	30–50 mm
High Temperature Liquids (80~150℃)	High insulation requirements	50–80 mm
Low Temperature Liquids (-40~0℃)	Anti-icing and anti-freezing	50–100 mm
Hazardous Goods or Chemical Storage Tanks	Requires strict insulation or anti-condensation	Customized according to process requirements, typically ≥ 50 mm

The thickness can be adjusted appropriately based on factors such as tank material, ambient temperature, wind speed, and insulation duration.
We provide matching polyurethane spraying machines and raw materials, and can customize the thickness and formula to your needs, ensuring both construction efficiency and insulation performance.

Accessories and Support

Electric air compressors

Suitable for environments with a stable power supply, such as factories and construction sites. They operate with low noise and are easy to maintain.

Diesel air compressors

Suitable for construction environments without power supply, powerful engine with a displacement of 970 L/min.

Diesel air compressors

Suitable for outdoor work or construction sites without a fixed power source. They offer strong power, wider adaptability, and can be used in conjunction with generators.

oil drum heater

Oil drum heating can quickly preheat polyurethane raw materials, reducing viscosity and improving fluidity. The heating temperature is adjustable from 0 to 200℃, suitable for 200L standard iron drums, with fast heating speed and uniform heating, preventing localized overheating.

Polyurethane planer

Polyurethane planers help remove excess foam, correct unevenness on sprayed surfaces, and achieve a clean, smooth surface before painting or panel installation. Lightweight and easy to control, these planers are suitable for applications such as wall insulation, roofing, and cold storage construction.

Mixer

The mixer is used to quickly and evenly mix polyurethane raw materials, ensuring that the liquid is fully blended before use, avoiding stratification and sedimentation, and improving foaming stability and construction effect.

Know More

buy raw materials and get machine for free

Our polyurethane tank insulation spray coating uses a high closed-cell formula with a closed-cell rate of over 90% and a thermal conductivity as low as 0.022 W/(m·K). This allows it to quickly form a dense, seamless insulation layer on the tank surface, significantly reducing heat loss.
The material has a controllable expansion ratio and strong adhesion (≥ 0.3 MPa), maintaining uniform foaming on vertical, horizontal, and large curved tank surfaces without sagging or collapsing.
The material has a temperature resistance range of -40℃ to 120℃, is resistant to aging, waterproof, and corrosion-resistant, and maintains stable insulation performance even after long-term use.
We also offer customized formulas to better suit customer temperature requirements, construction environments, and tank types, resulting in more efficient and durable insulation.

How to install spray foam machine

The following checks should be made before operation.

1. All joints from the host to the gun do not leak air or material,
2. be sure to separate A material and B material from the pump to the gun of the whole input pipeline, so as not to cause the whole system paralysis,
3.there should be safe grounding and leakage protection.
4. When the equipment stops working, the heating system should be tumed off and the power supply should be disconnected in time to avoid the decline of foaming quality caused by too long heating time.

Yongjia's price is 30% cheaper than Europe, but the quality is higher than European equipment

PU Spray foam machine tank insulation Success Stories

A chemical plant in Gujarat, India, used our high-pressure polyurethane spraying machine for the first time when upgrading the insulation of several vertical storage tanks. The local climate is hot and humid, and traditional insulation methods are prone to water absorption and delamination, affecting the temperature stability of the storage tanks. After using our spraying machine, the customer found that the equipment’s proportioning control was precise and the mixing was uniform. Even in high-temperature environments, it maintained stable pressure, preventing spray gun clogging and material spillage.

The equipment provides stable mixing and consistent pressure output, and even under high-temperature conditions, there were no issues with nozzle clogging or inaccurate proportions. The insulation layer of the storage tank is formed in one pass with uniform thickness. Yongjia’s technical team provided thorough training, enabling our operators to quickly become proficient in its use. We are very satisfied with this spraying machine and will continue to purchase from them in the future.
