Product features
- DC inverter compressor, indoor EC variable-speed fan, electronic expansion valve and variable-speed condenser fan provide stepless cooling capacity control and 30% energy savings.
- Cooling close to the heat source, combined with hot/cold aisle containment, reduces airflow cooling losses and improves air delivery and cooling efficiency.
- Multiple fans operate at their optimum efficiency points and provide redundancy.
- Intelligent controls adjust fan speed to cooling demand, substantially reducing fan energy consumption.
- Cooling/heating and constant-temperature-and-humidity configurations meet different application requirements.
- Components from established brands provide high reliability, a design life exceeding ten years and low maintenance costs.
- A 7-inch touchscreen and multiple temperature and pressure sensors display unit operating status for operation and maintenance.
- High airflow and a small enthalpy difference meet equipment-room requirements for a high sensible heat ratio.
- Uses R410A refrigerant.
- Automatically restarts after power restoration and resumes the operating state used before the outage.
- Standard RS485 communication interface; a communication protocol can be supplied.
- Extensive self-diagnostics, alarms and protection functions support safe, reliable operation.
