Making the World a More Comfortable Place
SANYO’s absorption technology is in evidence in
many aspects of our daily lives, from where we do
business to the places we choose to relax.
Type DE (Direct-fired Chiller/Heaters)
For the safety sake
Type NE (Steam-fired Chillers)
Type LE (Hot water-fired Chillers)
Before operating the unit
*To use the unit properly before operating, be sure to carefully read the operation manual.
*Installation should conform to regulations and laws such as Building Stan
