Taikisha's Technology

What is paint booths?

Paint booths apply intermediate and top coat on the object being painted, forming designs, and coating to protect the undercoat from ultraviolet rays and the wind and rain. The large size of these machines emphasizes technologies to make them more compact and save energy with air conditioning controls.

What is energy-saving technology?

Paint booths consume the largest amount of energy among paint processes. Taikisha has developed and delivered many energy-saving HVAC control systems and other systems that save energy like exhaust air recycling ones.

Can provide solutions to these problems

  • Want to reduce CO2 and enhance energy efficiency


As water-based paint has become more common, there is generally a water evaporation process (flash-off) in automobile paint processes after painting. With water-based paint flash-off facilities as well, use of heat pumps for dehumidification brings efficient water evaporation at low temperature and low humidity. In addition, its cost-efficient performance is well proved because it allows you to skip the cooling process that usually takes place after the flash-off process.


This energy-saving system lowers the humidity in water-based flash-off devices to promote evaporation of moisture in the coating film even in low-temperature environments, which reduces the heat load.

  • Reduction of the energy required for dehumidification

    A dehumidification rotor incorporating a heat pump is used in the dehumidifier to reduce the energy required.

  • Subsequent cooling process can be omitted

    The subsequent cooling process can be omitted by lowering the temperature in the water-based flash-off device.
