Hiespo

last updated：Oct 02, 2026

TOEI KAISHA, LTD.

Wherever you place it, it's a premium air conditioning spot. A heatstroke prevention solution that doesn't require a specific location and doesn't need installation—commercial portable air conditioner.

The portable air conditioner/Hiesspo does not require any piping work and can be easily moved with casters. It is effective in places where there is no permanent air conditioning system, in factories where specific areas become hot, or in locations that temporarily need cooling. It has a higher cooling capacity compared to typical spot coolers, with a lineup of five types ranging from 1 horsepower to 6 horsepower, including models with a maximum cooling capacity of 14.0 kW. With a Sirocco fan that can blow air over long distances, it releases cool air primarily in the direction of the airflow, making it effective in spaces that typical spot coolers cannot adequately address. It is suitable for spot cooling in factories, warehouses, construction sites, as well as for cooling break rooms, gyms, events, and golf practice ranges. In addition to cooling, Hiesspo also supports dehumidification, heating, and ventilation, making it usable throughout the year and ideal for needs that require changing locations between summer and winter.
