Provide A Heat-Controlled Space
For Your Cargo !

Heat damage

During the long distance transportation on the sea, in the daytime, the sunshine keep heating the iron-made containers, and raise the temperature terribly in the containers.

The Heat Damage brings a lot quality problems to the cargo like chemical reaction, melting and even self-ignition, etc.

Container Thermal Liners

Heat Solution

A total sealed environment created by HeatGuard CTL and Pallet Cover forms an envelop, which prevents movement of air, prevents convectional heat transfer and protects cargo that are stacked on pallets from dust, dirt and convection heat transfer during storage and in transit.

Container Thermal Liner

HeatGuard CTL

HeatGuard Container Thermal Liner (CTL) and is made of high reflective aluminum material which reflect 95% of radiant heat.

This provides thermal Insulation function and stable temperature environment for the cargo in the container during ocean voyage and storage in the warehouse.

HeatGuard prevents the temperature from rising and dropping in a big range. So it effectively save the cargo from the quality loss.

Container Thermal Liners

How it works

HeatGuard container thermal liner is make of high reflective aluminum material which reflect 95% of radiant heat.
​ The special installation method also creating air gap in between the container wall and roof to prevent conductive heat transfer.

A total seal environment created by HeatGuard liner form a envelop which preventing movement of air and preventing convection heat transfer.

Effect

In summer, when ambient temperature is 36°C, container inner temperature will arrive 55-60°C,but the temperature inside liner bag is just in 40-45°C, then have 10-15°C temperature difference. It will have a better insulation effect to use with pallet cover together.

Temperature Tracking Test

A:data loggers recorded temparture during transport with a container.

B:data logger between CTL and the container.

C:data logger inner CTL.

Material

HeatGuard material is made of three material types in 5 or 7 layers structure with pure aluminum foil on two sides and middle layers as barrier layers.

Compared with traditional bubble film and EPE, this material is light and thin and convenient to handle. It has high resistance strength, and can be recycled to use.

Technology

• Unleaky seal
• Good breaking strength and repeated use
• Double protection for heat insulation and warm keep, effect increased by 40%

Characteristic

• Excellent thermal insulation effect, which can keep 8-15 ℃ temperature difference between container inside and outside.
• It can keep temperature to rise and fall slowly.
• To prevent the goods from mildewing or rusting.
• Green environmental protection in material, no pollution.
• Light material, without affecting the loading space.
• High breaking strength in material, not easy to be damaged and repeated use.
• Humanized design, convenient installation, not affect the work efficiency.

FAQ

Can HeatGUARD replace a refrigerated container?
HeatGUARD is not an active cooling system and does not generate refrigeration. It is a cost-effective alternative for cargo that requires temperature stabilization rather than constant refrigerated temperatures.
What are the main benefits of using HeatGUARD?
HeatGUARD helps reduce temperature fluctuations, prevent condensation, protect cargo quality, lower transportation costs compared with reefers, and improve delivery reliability.
How does HeatGUARD differ from ordinary reflective liners?
HeatGUARD uses a complete six-sided liner design with reflective insulation and an enclosed air barrier, providing more effective protection against heat transfer and humidity than simple wall coverings.
How much temperature protection can HeatGUARD provide?
The level of thermal protection depends on factors such as container position, shipping route, season and transit duration. HeatGUARD can maintain a temperature difference of 10–20°C between the inside and outside of the liner under certain shipping conditions.
Does HeatGUARD protect against condensation?
Yes. By reducing rapid temperature fluctuations and limiting moisture exchange, HeatGUARD helps minimize container rain, condensation, mould, corrosion and moisture-related cargo damage.
How can I verify its performance?
HeatGUARD supports shipment validation using temperature and humidity data loggers. Recorded data can be compared inside and outside the liner to evaluate thermal performance.
What container sizes are available?
HeatGUARD is available for standard 20GP, 40GP and 40HQ containers. Custom sizes are also available for special containers, trailers and other transport equipment.
