In commercial and residential facilities, HVAC systems are essential for maintaining comfortable indoor environments. However, over time, scaling and biological fouling can accumulate in the condenser tubes, leading up to a 30% reduction in the heat transfer efficiency. This buildup forces compressors to consume more energy, diminishing overall system performance and increasing operational costs. Additionally, frequent maintenance and unexpected downtime can disrupt daily activities and tenant satisfaction. Today, world product per capita decreased by 0.25% due to fouling.
Traditional Approaches
Conventional methods that address fouling and scaling involve periodic manual cleaning and chemical treatments. While these methods can temporarily restore efficiency, they often require system shutdowns, involve hazardous chemicals, and incur significant labor costs. Moreover, the environmental impact of chemical use and disposal is a growing concern.
CQM GROUP’s Innovative Solution
CQM GROUP offers the Automated Tube Cleaning System (ATCS), a cutting-edge patented solution, designed to maintain optimal heat transfer in HVAC condensers.
The ATCS prevents the formation of scaling and biological fouling in the tubes of HVAC condensers by periodically injecting cleaning balls into the system. These balls travel through the tubes, effectively keeping the internal surfaces clean without interrupting system operations. The ATCS is fully automatic (PLC controlled) and works continuously while the heat exchanger is operational, eliminating the need for inconvenient shutdowns or costly maintenance.
Keeping the condenser clean can save up to 30% of the energy required by the chiller, leading to significant reductions in operational costs.
The ATCS operates seamlessly without requiring system downtime, ensuring uninterrupted comfort for building occupants.
By eliminating the need for chemical treatments, the ATCS offers an environmentally friendly solution that reduces handling risks and disposal concerns.
Regular automated cleaning prevents scaling and fouling, protecting HVAC components and extending their operational life.
Energy and cleaning savings usually bring the system’s ROI to less than two years, while the effect of the system is noticeable in a matter of months.
Constant Maintenance, No Shutdowns
Clean condenser tubes improve efficiency, heat exchange and thermodynamic processes.
Chemical-Free Cleaning
Zero-chemicals and constantly-circulating soft cleaning-balls keep your system at top efficiency while promoting sustainability and green practices.
Zero-ball Loss
Patented collector keeps all the cleaning balls in the system, without the need for backwash. Stock can be refreshed without downtime.
Plaza Hotel Casino, Las Vegas, Nevada
Year of installation: 2011
Problem: Two identical chillers were compared; one with ATCS and one without.
Solution: ATCS installed on Chiller 1 to maintain performance during hot summer months.
Results: 11.8% energy savings over 61 days.
Chiller 1 outperformed Chiller 2, demonstrating the effectiveness of ATCS.
Sonda Data Center, Quilicura, Chile
Year of installation: 2016
Problem: Due to fouling and scaling accumulation, an internal heat exchanger in the data center cooling tower was blocked.
In order to reduce the heat, additional cooling towers had to be operated.
The delta T of the outgoing water temperature compared to the return water was too low and insufficient.
The problem was diagnosed through temperature difference data and through visual diagnosis of the blockage that had formed.
Solution: An SRCT system was installed.
Results: Heat exchanger remained clean.
Water temperature Delta T achieved designed goal.
As a result of the success three additional systems were purchased.
