Taikisha's Technology

What is environmental testing equipment?

Taikisha provides high-quality and compact equipment for high-precision environmental testing system with energy-saving based on our abundant experience.

What is temperature and humidity control technology?

You can ensure product's quality and overall performance by thermal testing under operational environment. Control techniques for adjusting temperature and humidity to set point are necessary to reproduce the required environment.

Can provide solutions to these problems

  • Want to reduce CO2 and enhance energy efficiency
  • Want monitoring and control


This system supplies air to engines at a constant temperature and humidity during an engine unit test.


  • Control accuracy of ±0.5°C
  • Non-stop and single-step operation in flexible response to cooling loads in the range of 0 to 100%
  • Cooling and re-heating with the high-temperature refrigerant at the outlet of the compressor as a heating source.
    Higher COP than the cooled-water type (annual power consumption reduced 30%)
  • Compact type integrating a freezer, HVAC, and control panel
