Heat pumps are equipment and technologies that collect heat from thermal source such as the atmosphere and use it as an energy, and are used in hot water supply equipment such as buildings and factories. Since it is possible to efficiently generate thermal energy with a small amount of electrical energy, it is attracting attention as an environment-friendly technology as well as energy saving. We have various heat pumps in Thailand.
CO2 heat pump
Supply sufficient hot water with overwhelming cost performance. We are selling the eco-friendly heat pump “UNIMO” in Thailand.

The CO2 heat pump is an equipment that supplies hot water using carbon dioxide as refrigerant, which is a natural refrigerant. In Japan, it is known by the name of “EcoCute”. Our “UNIMO” has a lineup of three models depending on the thermal source (air or water) used. All of these products can steadily supply hot water at 90 degrees Celsius.
The world’s first model that uses both heat sources is excellent in cost performance because it can be operated for a long time with high efficiency by flexibly switching the thermal sources. If you are looking for an environmentally friendly high efficiency heat pump in Thailand, please contact us.

Ammonia heat pump
Ammonia, which is the most effective in preventing ozone layer depletion and global warming, is used as the refrigerant. We are selling heat pumps that are friendly to the global environment in Thailand.

Our ammonia heat pump provides a stable supply of hot water with a maximum water temperature of 85 degrees Celsius. It can also be used as a package for reciprocating and screw compressors and can function as an independent unit using drainage or geothermal heat sources. It can also be integrated into existing refrigeration systems as a heat recovery equipment. If you are looking for a highly functional ammonia heat pump in Thailand, please contact us.
