5 Plus Technology is the technology invented by Thai.  This technology was granted by National Research Council as the Innovative Technology in Air-Conditioning and Refrigeration Industry.

It had been well-proven by NECTEC (Ministry of Science & Technology) and Department of Renewable Energy Development (Ministry of Energy) that it can save energy on air-conditioning that operate on part load in between 15% to 40%.  In addition, this technology can enhance cooling capacity on the same air-conditioning units and prolong compressor’s life time, either.  It is the mechanical parts unlike other technologies that are electronics based.  Therefore the operating and maintenance of this technology is so little.
