Total solution for industrial drying

Reducing energy costs 

Through a simple structure, compared to the conventional hot air method, heat is transferred in the form of radiation that does not require a medium during heat transfer, so only the target conductor is directly heated, resulting in high energy efficiency.


As no fossil fuels are used, there is no greenhouse gas emission and no separate environmental facilities required.

Maintenance convenience

Simple structure, low maintenance cost due to no requirement for peripheral equipment

Increases space utilization (no need for environmental facilities)

Improving working environment

After drying, the post-process work environment is improved by increasing temperature mainly on substrate surfaces, thereby reducing the need to install a separate cooling device after drying

Quality improvement

Securing high-quality performance, improving quality by more than 90% compared to hot air (saving costs and rework time)

Fire prevention

Hot air method causes continuous fire in furnace
