Core Technologies


SANYO refrigeration technology is an important part of Vertical Component Integration™ expressed through products of SANYO Electric Biomedical Co. Ltd. Since it's inception in 1967, the SANYO Electric Company, Ltd. Compressor Division has attained a solid record of achievements in research and development projects. For nearly 35 years, SANYO has been instrumental in improving the quality and performance of compressors in worldwide consumer and industrial applications.

SANYO Compressors
The SANYO Compressor Division has originated over 300 compressor-related international patents. SANYO refrigeration technology and compressor component quality, already recognized throughout many industries, is a critical advantage to SANYO Electric Biomedical Co. Ltd., particularly with ultra-low and cryogenic freezers, biomedical freezers and refrigerators, and blood bank products.

  • The SANYO Compressor Division produces more than fourteen compressor types, with over 600 specific models including hermetic, semi-hermetic and scroll compressors, each designed for proximate applications within operating parameters.
  • Compressors, refrigerants and lubricants used in SANYO ultra-low and cryogenic freezers meet demanding internal specifications required of critical storage installations. Compressor upgrades and improvements, factory training, worldwide availability and technical support are important SANYO advantages that cannot be matched by competitive companies who must acquire compressors acquired from third party manufacturers, or request costly programmed modifications that restrict and inhibit improvements.

Here, only the SANYO Vertical Component Integration™ advantage can yield such benefits in safety, convenience, serviceability and long-term durability.

Other companies depend on SANYO compressors as well. SANYO refrigeration components are incorporated into thousands of "private label" products ranging from easily recognizable household appliances to more esoteric industrial and scientific equipment for biotechnology, aerospace and more.These include:

  • household and commercial air conditioners
  • household and commercial refrigerators and freezers
  • commercial, institutional and restaurant ice machines
  • industrial freezing systems
  • cold traps
SANYO Condensers
The SANYO Compressor Division also manufactures integral condensing units used in SANYO refrigerators and freezers. As another example of Vertical Component Integration™, this condenser development capability assures continuity in biomedical product design, and assures an optimum match of component, application and quality control throughout the entire SANYO company.
