About the Helios TCS®




Proven, Ultra-Reliable Performance

The proven leader in heat exchanger tube fouling prevention, the Helios tube cleaning system is the preferred solution for the world’s most demanding and sophisticated district cooling system operators.

Helios TCS installations have completed millions of cleaning cycles over the last decade with operational reliability above 99.97% and zero cooling process interruption. 

The Helios system is the tried-and-true solution required by the district cooling, utility, and petrochemical industries.

Optimized Chiller Energy Efficiency

Reduced Maintenance Hours

By utilizing Helios systems, facility operators relieve themselves of the burden manually brushing heat exchanger tubes, which can require thousands of man-hours each year. Instead, skilled mechanics and technicians can be freed up to tackle higher-value maintenance tasks.

Increased Cooling Capacity

When exchanger tubes get fouled, less heat can be extracted from the building or process, especially when outside air temperatures climb and condenser water temperatures approach or exceed full-load design conditions. Installing a Helios tube cleaning system ensures that your water-cooled chiller delivers maximum cooling when you need it most.

Maximum Chilled-Water Plant Availability

Important for process-cooling applications (e.g. data centers, industrial or manufacturing process cooling, etc.).  Helios installation eliminates downtime for manual tube cleaning, ensuring n+1 operation is possible even when chiller mechanical failures occur elsewhere.

Modular Expansion for Flexibility

A single Helios skid and controls package can service up to five (5) heat exchangers. After the first Helios system is installed, expanding the system to additional chillers is as easy as adding a dedicated Collector and Ball Trap for each chiller.

Engineered and Fabricated for Compliance & Longevity

Helios systems are designed and fabricated in the United States, and compliant with the most exacting engineering standards on the planet. Unparalleled reliability, and a life cycle outlasting the critical performance equipment the Helios serves, is the goal.

Customized Design Solutions for Applicability & Reduced Installation Cost

Custom design-build solutions are available in a wide range of materials, dimensions, and configurations for specialized applications including seawater, elevated pressures, and unique piping configurations.

University of Virginia Case Study

Campus-wide installation of the Helios TCS® resulted in more than $1.05 million in savings.

The University of Virginia sought opportunities to improve energy efficiency in plant utilities.  The Helios® TCS improved energy efficiency in plants serving 10M+ square feet and 27,000 tons of cooling capacity from 20 chillers.


Application Industry Sectors

The magnitude of shell and tube fouling as an energy waster is one of the least understood costs to our economy. Commercial buildings account for nearly 40% of total energy consumption in the United States and of that up to 50% of their energy is consumed by HVAC systems. Water-cooled chillers are incredibly effective, but they suffer from endemic tube fouling preventing their complete optimization. Historically, fouling in tubes causes up to 30% efficiency loss. It has been tolerated and mitigated by manual cleaning by operators for over a century because there was no solution. Until now!

What Customers Say About the Helios TCS®

“We have found real value in continuously maintaining clean condenser and evaporator tubes. We save energy, sure, but we also provide better cooling and at the same time, reduce the maintenance requirements of our chillers.”


Travis T. – Power Plant Manager

“Savings include energy, maintenance & elimination of workload associated with fouling.”


Pat L. – CCantral Utility Plant Lead

“At first we thought the Helios system might be too good to be true. Now, nearly 10 years later, we can’t imagine our operation without it.”


Justin C. – Chiller Plants, Associate Director

“We used a third party to validate Innovas ’ savings numbers and they turned out better than claimed.”


Mike O. – Cooling Plant Manager
