■ Up to 80% energy savings with heat pump balance control (patented). By equipping a heat pump balance control and inverter speed control refrigeration unit, we achieve approximately 80% energy savings compared to conventional air conditioning and heater control methods for constant temperature and humidity. ■ After reaching the set temperature, the auxiliary heating heater is turned off to cut unnecessary power consumption. Reheating is done using the waste heat generated during air cooling, eliminating the need for electric heater input, resulting in significant energy savings. ■ Equipped with a DC inverter-driven compressor. Significant energy savings are achieved through unique speed control, optimizing operation according to load conditions. ■ Both indoor and outdoor units are equipped with inverter fans. Combined with a newly developed dedicated controller, we have realized unique refrigeration cycle optimization control operation. ■ Achieves high precision response (comparable to heater PID control) that is impossible with conventional air conditioning units or traditional reheat control. ■ No local instrumentation work required. With the control panel built-in, there is no need for local instrumentation work, allowing for easy realization of constant temperature (constant humidity) spaces with minimal construction. ■ Easy local trial operation adjustment. The unitized air conditioning system allows for quick and hassle-free trial operation adjustments after installation. ■ Easy system design. Necessary equipment is systematized, eliminating the need for cumbersome system design.

■ Powerful dehumidification. The air intake at 27℃ and 70% humidity is dehumidified all at once to 23℃ and 28%! Achieves a frost limit of 3.5℃ using only the refrigeration cycle. ■ No defrost operation required. Continuous operation without defrosting is possible with unique refrigerant control! ■ Up to 65% energy-saving operation. Equipped with compressor speed control to cut unnecessary power consumption! Energy saving is achieved by controlling the compressor speed when the set humidity is reached. ■ CE marking machines in the lineup. UL/CSA61010-1 compliance evaluation report can be submitted.

Cool the intake air at 35℃ down to 8℃ using all fresh air.

■Freon-free Air Dryer The heatless air dryer QSQ series removes water vapor from compressed air by adsorption using a desiccant. Unlike refrigerant-type air dryers, it can supply freon-free air with a low dew point. The regeneration of the desiccant is achieved by passing a portion of the dried air through it (purge air). ■Energy-saving dew point sensor is standard equipment. ■All functions are indicated by lamps. ■Compact and lightweight, with easy maintenance.
