Automation Components, Inc. (ACI) creates, manufactures, and distributes building automation sensors for the heating, ventilation, and air conditioning (HVAC) Industry. Dpstar is ACI Authorised Distributor in Malaysia. Our product lines include Temperature Sensors, Relative Humidity Sensors, Current Sensors, Pressure Sensors, Gas Sensors, and Wireless Sensors.

ACI’s most cost-effective controller, the LD310 is easy to install and provides reliable leak detection as either a standalone device or integrated into a larger BMS platform.

What Sets ACI’s LD310 Apart?

  • Zone leak detection system alarms when water comes into contact with the attached sensing cable or spot detector. It is the right fit for spaces where sensing cables and spot detectors are visible so leaks can easily be located.
  • A supervised system, the controller continuously monitors the cable for leaks, breaks, and disconnects and sends an alarm notification when one is detected.
  • Local alarm annunciation. Onboard audible and visible alarms notify users of leaks and faults in real time.
  • Patented leak detection technology. Our cables dry and reset quickly so they’re ready to detect the next issue.

Applications

  • Ideal for smaller contained areas like air conditioner condensate pans.
  • Frequently used in facilities with pumps, chillers, boilers, and water control valves.
