Energy-saving construction No need for pulley and belt adjustments Low maintenance No need for maintenance or replacement of pulleys and belts Achieves high APF2015 and high COP By adopting a DC fan motor, we have achieved a high APF2015 and high COP. Reduction in power consumption By using a DC motor for the indoor fan motor and improving the low-speed performance of the compressor as well as optimizing the refrigeration cycle control, we have significantly reduced the power consumption over time. Standard motor capable of handling high static pressure In conventional units, a motor upgrade was necessary for high static pressure applications, but with the beltless system, high static pressure can be handled with the standard motor. Fan speed settings can be adjusted from the operation panel During trial operation or after delivery, it is possible to change the speed according to the external static pressure and airflow on-site. Expanded standard range for external input/output - Two output terminals are newly equipped as standard (see table below) For more details, please contact us.

Self-Demand Function Equipped Automatically detects current and performs demand control. It cuts power consumption exceeding the set power value, contributing to maximum power suppression. Temperature Range Limitation A function that sets upper and lower limits for temperature settings via the operation panel. By restricting the temperature setting range on the operation panel, it helps prevent excessive cooling or heating and supports energy conservation. Automatic Return to Set Temperature Even if the set temperature is temporarily changed to strengthen cooling or heating, if an automatic return time is set, it will automatically revert to the initial set temperature, suppressing excessive cooling or heating. Operation Lock Function Restricts operations from the operation panel. It prevents changes due to incorrect operations of "set temperature" and "operation switch." Forgotten Shutdown Prevention Timer Function A function that automatically stops operation after a certain period has elapsed since the start of operation. The set time can range from 30 minutes to 24 hours. Lin For more details, please contact us.

Overview A renewal type that can utilize existing piping without worrying about the cold. It demonstrates high heating performance even at low outdoor temperatures. Shortened renewal work process without piping cleaning A unique renewal filter is built into the outdoor unit, allowing for the removal of moisture and oxidized components of the existing refrigerant oil in the existing piping. Additionally, by using the renewal kit (optional), it eliminates the need for cleaning the existing piping even if the compressor of the existing unit is faulty, thus shortening the renewal work process. Equipped with automatic determination function for additional refrigerant filling It features a dedicated charge port and a refrigerant quantity determination algorithm based on subcooling detection, automatically determining the appropriate refrigerant amount. Maximum piping length from the first branch is 60m, saving construction costs by consolidating multiple refrigerant systems The maximum piping length from the first branch to the indoor unit has been extended to 60m. This makes it easier to consolidate multiple refrigerant systems near the outdoor unit. For more details, please contact us.
