On-Line HVAC Chiller Tube Cleaning

ATCS-HVAC conserves the heat exchange efficiency of condenser tubes of water cooled air conditioning chillers by maintaining the condenser tubes free of fouling. Rubber balls are recirculated at set time intervals to capture deposits accumulated in the condenser tubes.

Fouling in the chiller’s condenser tubes is a costly problem

  • Energy consumption spikes: as little as 0.3mm of dirt in the chiller’s condenser tubes increases energy consumption by 10% or more..
  • Environment is affected: Greenhouse gases are released to the atmosphere.
  • Profits drop: expenses increase due to extra energy consumption and repeated tube cleaning.
  • Conventional tube cleaning cleaning methods are temporary, expensive, cumbersome and progressively inefficient.

Advantages of ATCS-HVAC over conventional systems

  • Cost-effective: maximizes chiller efficiency for multiplied savings in operation, manpower and energy – up to 25% savings in the chiller’s annual operation cost.
  • Environmentally safe: uses no chemicals, produces no hazardous waste.
  • Continual operation: works while the chiller is on.
  • Automatic: computer-timed cleaning with no need for intervention.
  • Reliable: high-performance parts.
  • Efficient: one ATCS-HVAC installation can handle an entire facility.
  • Measurable savings: reliably measure savings with installation of the optional Integrated Performance Tracker.

How ATCS Works

The CQM ATCS is installed on steam condensers and keeps tubes clean without human intervention. The system periodically injects into the tubes sponge balls that are slightly larger in diameter then the tubes themselves. The natural pressure head pushes the balls through the tube, which is thus rubbed clean. The balls are then trapped in the outlet of the condenser, where they are prepared for the next cleaning cycle.

Typical comercial installations take less than 25 man hours, and requires only 8 hours of process shutdown. Trapping units are available in a variety of shapes and flow configurations to accommodate piping routes design and available space for installation.

Performance Tracker

  • Dedicated software that monitors HVAC system performance in real-time.
  • Fully automatic data collection.
  • Remote access allows monitoring from anywhere via a web link.
  • Analysis to quantify savings in energy, operational costs, ROI, pollutants toxic waste, and more.
  • Report generation on environmental impact and energy use.
  • Complies with requirements for ESCO savings validation.
  • All features are user-friendly with a short learning curve.
