Residential Unitary DX Split Air Conditioning Units 25 kW With Fully Hermetic Volute

25 kW EKDB100A(R)  high static pressure duct type air conditioning unit

Specifications:

Description:

1. Outstanding Performance    

    Outstanding fans, motors and other components specially designed for air conditioners ensure that the unit operates smoothly.

    Brand-new dustproof and rustproof painting makes sure that the outdoor unit looks new after many years of operation.

2. Easy Installation    

    Featuring a high static pressure design, the indoor unit can supply conditioned air over a long distance, enabling customers to select the installation site as required. To service any component of the unit, you only need to remove several screws on either side of the unit.

    The connection pipe between indoor and outdoor units reaches up to 50 m, and the height difference can reach 20 m.

    The outdoor unit adopts top air supply, allowing combined installation of multiple outdoor units for pleasant appearance.

3. Silent Operation    

    The indoor unit features an efficient and low-noise centrifugal fan as well as sound-absorbing and thermal insulation inner walls to ensure silent operation.

    The indoor unit can be mounted on a far-away ceiling to make the conditioned room more silent.

    Unique insulation design for compressors ensures an outstanding insulation performance.

    The outdoor unit uses new spiral fans, which have smooth an air suction structure, greatly reduce turbulent flows, and lower the air flow noise.

4. Smart Control        

    The smart microcomputer controller supports four operation modes: cooling, heating, fan, and auto control. It also provides timed ON/OFF, auto-defrosting, and fault display functions.

5. Increasing Efficiency and Saving Energy   

    The unit uses a brand efficient volute compressor, which consumes less electricity while providing the same cooling/ heating capacity. The compressor features a small volume and stable running. The unit uses advanced thermal expansion valve control technology to accurately control tributary flows.

6. Power Recovery and Memory Functions   

    During operation, if the power fails, the unit can automatically start once the power resumes no matter how long the power failure lasts. After starting from an exceptional power failure, the unit automatically resumes the running status before the power failure. This function is not enabled upon factory delivery. It needs to be set through DIP switches on site.

7. Wide Application Scope     

    The unit has strong adaptability to the environment. It can normally perform cooling when the outdoor temperature is between 18°C and 48°C. It can normally perform heating when the outdoor temperature is between -10°C and 27°C.

    The outdoor unit of the low-temperature cooling unit uses a brushless DC motor to control the rotation speed of the condensing fan, efficiently expanding the operating range of the unit and allowing it to normally perform cooling when the outdoor ambient temperature is between -10°C and 48°C.

    Multiple types of units with electric heater boxes or hot water coil boxes are available.

8. Optimized System and Quiet Running        

    The outdoor unit produces a low noise. The system is optimized to suppress vibration and noise during operation, achieving quiet and stable unit running.

9. Wide Voltage Range      

    The unit normally runs within ±10% of the rated voltage

 10. Multiple Protections      

       The unit provides high/low voltage protection, air exhaust temperature protection, overload protection, protection against phase loss or inversion, minimum downtime protection, minimum running time protection, and so on, minimizing damage to the unit. Faults are alarmed and displayed at the first moment, facilitating
troubleshooting. The unit provides phase loss/inversion protection. In the case that the power supply  encounters phase loss or inversion, the protection device protects the running unit.Protection against phase inversion is designed for volute compressors.

11. Dual-sided spraying for long lifecycle

     The shell of the outdoor unit is sprayed with anti-UV and pure polyester mineral highlighter on dual sides, effectively prolonging the lifecycle of the unit.
