The Automatic Tube Cleaning System (ATCS) provides energy-saving, on-line condenser tube cleaning for water-cooled chiller applications. The system periodically injects sponge balls into the condenser water stream, and prevents condenser tubes from developing scale or microbial fouling deposits.

Exceptionally useful in the HVAC industry, especially in cooling tower applications, the TEKLEEN® line of ABW (automatic backwash) filters eliminate contamination, which can circulate through heat exchangers, chillers, and compressors, making the cooling system pump harder, thus lowering the efficiency of the system, said the company. 

The FS-Series are flexible shafts for tube-cleaning machines. The series has been redesigned and improved to be 40 percent stronger and are field repairable, the company said. According to the manufacturer, the new design has the holding power of more than 200 pounds of exerted force. 

The Gruvlok® KNX Series hydronic hook-up kits integrate the typical 54 components required to connect piping to hydronic heating or chiller system equipment into a pre-engineered, pre-assembled, and pre-tested kit of only four components, saving up to 80 percent on labor compared to traditional connection methods.

The Redi-Purge noncondensable gravity flow purge 007 Series units are a virtual drop-in replacement for purge units that pull from and return to the condenser. The series includes models 007-11-C3 and 007-123-C3. According to the manufacturer, the refrigerant charge does not have to be pulled to install.

The expanded line of AquaSnap® 30RAP air-cooled scroll chillers is now offered up to 150 tons. AquaSnap 30RAP chillers are available with several factory- and field-installed options and accessories, including a hydronic system option that maximizes pump efficiency and makes installation even easier.

It isn’t just the small business owners and homeowners who are looking to increase the energy efficiency of their buildings and homes — it’s the big utility companies as well. What did one utility company recently do upgrade its overall efficiency?

The YORK® YVWA water-cooled screw chiller features energy-saving variable-speed technology. The design of the chiller, with energy-saving variable-speed technology, helps cut energy costs and carbon emissions by as much as 30 percent, said the company.

HVAC contractors — both residential and commercial — place a great deal of emphasis on system maintenance and how it directly relates to lower operating and service costs. Here some HVAC contractors weigh in with tips that will prevent a lot of unnecessary chiller service or replacement.
