Not only for commercial air conditioners, but also for gas heat pumps, refrigeration, and refrigeration systems where the refrigerant becomes high temperature and high pressure, the fluid stirring device 'α-HT1000' is compatible.

The "α-HT" is a commercial air conditioning fluid stirring device that purifies the refrigerant and maintains its condition, achieving a reduction in air conditioning power consumption. This device successfully enhances the efficiency of heat pump systems such as air conditioners from a completely different perspective by applying fluid dynamics. It reduces the power of the outdoor unit, shortens operating time, allows for operation at low current, and can be used during heating. Installation is simple, requiring only the addition to the existing refrigerant pipes, and once installed, it requires no maintenance. 【Features】 ■ Easy installation ■ No running costs ■ No maintenance required ■ Usable for heating ■ Usable in refrigeration and freezing machines ■ Inserted into piping rather than requiring modifications *For more details, please refer to the catalog or feel free to contact us.
