Chilled Water Unit FAQ
Q: What is the typical lifespan of a Chilled Water Unit?
A: With proper maintenance, our Chilled Water Units typically last 15-20 years. The actual lifespan depends on operating conditions, water quality, and maintenance frequency. Regular servicing including tube cleaning, refrigerant checks, and component lubrication can significantly extend the unit's operational life.
Q: How often should a Chilled Water Unit be serviced?
A: We recommend quarterly inspections for heavily used units and semi-annual maintenance for standard operation. Key maintenance tasks include checking refrigerant levels, cleaning heat exchangers, inspecting electrical connections, and verifying pump operation. Annual professional maintenance by certified technicians is crucial for optimal performance.
Q: Can a Chilled Water Unit be integrated with building automation systems?
A: Yes, all our Chilled Water Units come with BACnet or Modbus communication protocols standard, allowing seamless integration with most building automation systems. This enables remote monitoring of temperatures, pressures, flow rates, and energy consumption, as well as automated scheduling and alarm notifications.
