Energy Solutions


U.S. Chillers looks past the flanges of the chillers and walks the entire facility to provide our partners with potential energy, water, environmental and operational savings and improvements. Our goal is to define, develop, and deliver specific solutions to improve overall energy efficiency. After collecting and reviewing the data, we perform an energy and feasibility study to offer an energy solutions recommendation. The resulting energy solutions can lead to a cheap, efficient, environmentally friendly chiller operation going forward. We have saved many of our clients millions of dollars through these projects, and we aim to do the same for new clients. Below are some examples of energy solutions that we commonly offer clients.

Chiller Retrofits

USCS Engineers are factory trained on all major brands of centrifugal chillers.  We perform Smardt Factory Certified Turbocor Oil-Less Magnetic Compressor Retrofits / Energy Efficiency Upgrades / Refrigerant Conversions / Microprocessor based control panel modernization and upgrades /Chiller VFD Installations/ Refrigerant containment and tracking services as per EPA requirements and Chiller Plant Energy Control System Engineering and Installation.

Automatic Tube Cleaning System

The Automatic Tube Cleaning System is installed on heat exchangers and keeps the tubes clean without time-consuming intervention. Data shows that the average annual cost savings in energy production can range anywhere between $40,000 and $65,000 or more depending on the size of the chiller. Waste due to heat exchanger fouling causes the typical commercial air conditioning energy bill to increase 5% to 25% more per year than if the heat exchange tubes were maintained clean.


USCS Condenser Air Pre-Cooler


All USCS Condenser pre-cooler systems are designed, engineered and manufactured to attach directly to the condenser section of air-cooled chillers. The pre-cooler is designed to operate by utilizing the airflow from the Condenser fan of the existing air-conditioning or refrigeration equipment, relying entirely on the evaporation of water. As water passes downward through the media, the air velocity of the condenser fan causes some of the water to evaporate, ultimately cooling the air before it reaches the condenser coil. The lower the entering condenser air temperature is reduced, the more efficient the air-cooled chiller operates, which results in the consumption of less energy.

Not only does the chiller perform more efficiently with a pre-cooler, it also has to work less. Most users find increased efficiency across a range of increasing dry bulb temperatures when compared to a chiller without a pre-cooler. Our experience with energy savings has shown significant reduction in the total KWH consumption of up to 15% during the hottest part of the day, with up to a 20% reduction of compressor head pressure.



  • Reduce chiller energy consumption by 10%
  • Reduce utility electric bills
  • Condenser pre coolers transform air cooled chillers to be as efficient as many District Cooling plants in the region, 1.1 Kw per ton (includes DC chillers, condenser pumps and cooling towers)
  • Gain LEED points toward Green Building Certification
  • Completely eliminate Hot Air Recirculation ill effects
  • Complete coil Protection from Hail Damage.
  • Shade to your Condenser Coil, further reducing head pressure due to coil solar gains.
  • ROI generally less than 1 year payback on the system.

Pulse~Pure® Water Treatment System

Pulse~Pure® provides a complete water treatment system for evaporative cooling equipment, which significantly reduces the environmental impacts associated with the production, shipping, handling and storage of chemicals. This is a physical water treatment technology in which recirculating water from the evaporative cooling system passes through the Pulse-chamber, where it is exposed to alternating high frequency electric fields. Pulse-Pure solves all three critical challenges of water cooled systems – scaling, biological contaminates, and corrosion.
