Frequently Asked Questions - EWAT570B-SLA2-VFDFAN DAIKIN
What type of product is the Daikin EWAT570B-SLA2-VFDFAN?
The Daikin EWAT570B-SLA2-VFDFAN is an air-cooled screw chiller designed for commercial and industrial air conditioning. It uses a screw compressor and air-cooled condenser to provide efficient cooling.
What is the cooling capacity of this unit?
The unit has a cooling capacity of 570 kW, making it suitable for large buildings, industrial processes, and district cooling applications. The capacity is measured under standard conditions (e.g., entering water temperature 12°C and ambient 35°C).
What type of power supply does it require?
The chiller requires a 400V three-phase (3N~) 50Hz electrical supply. It is essential to have the correct electrical infrastructure to handle the rated power consumption of 190 kW.
What refrigerant does the EWAT570B use?
This model uses R-134a refrigerant, which has a relatively low global warming potential (GWP) and is widely available. The system is designed to minimize refrigerant charge while maximizing efficiency.
How often should maintenance be performed?
Regular maintenance is crucial. It is recommended to perform monthly inspections of the air filters and condenser coils, and semi-annual checks of refrigerant pressures, electrical connections, and water quality. Annual full-service maintenance by a certified technician is advised.
What safety features are included?
The unit includes high and low pressure switches, thermal overload protection for the compressor, an anti-freeze thermostat for the evaporator, and phase monitoring to prevent operation under incorrect phase conditions.
Can the chiller be connected to a building management system (BMS)?
Yes, the chiller is equipped with BMS integration capabilities, including protocols such as Modbus and BACnet. This allows remote monitoring, alarms, and setpoint control from a central system.
What is the noise level of this unit?
The noise level is approximately 82 dB(A) at a distance of 1 meter. For installations requiring lower noise, optional sound attenuation enclosures can be provided.
What are the operating temperature limits?
The chiller is designed to operate in ambient temperatures ranging from -15°C to 50°C. For lower temperatures, winter operation kits are available. The leaving water temperature can be set between 5°C and 20°C for cooling mode.
Where can I find spare parts and how repairable is it?
Daikin has an extensive network of authorized distributors and service centers. The chiller is designed with accessible service compartments and all major components, such as compressors, valves, and control boards, are replaceable. Spare parts are typically available for 10 years after the model is discontinued.
