Achieving Sustainability Goals Through Improved Closed-Loop System Efficiency

Facilities are continuing to pursue increasingly ambitious sustainability goals to help meet their internal directives. This has become a critical focus area for many facility managers and environmental teams within all sectors and industries. While major capital projects tend to receive the most attention, many facilities have found that smaller, targeted, reductions in energy consumption can be achieved by looking more closely at existing systems, specifically closed-loop heating and cooling. Whether the focus is on reducing carbon footprint, reducing natural gas usage, or simply extending the life of equipment, there is one specific sustainability product called Endotherm has been shown to help achieve all three.

Endotherm is an energy saving additive designed specifically for closed-loop heating and cooling systems that works by improving thermal efficiency and increasing heat transfer. This allows facilities to achieve desired temperatures with less overall energy input, resulting in large cost savings. With current energy market volatility, many facilities have found peace of mind by utilizing products like Endotherm to help them become more sustainable and less dependent on outside forces.

The benefits of improved thermal efficiency extend far beyond utility savings. Reduced energy consumption can directly lower greenhouse gas emissions, decrease natural gas usage, and help organizations achieve internal sustainability targets without the need for major capital investments.

Real-World Results: Life Sciences & Pharmaceutical Facility

A leading life sciences and pharmaceutical manufacturer implemented Endotherm across several closed-loop heating systems as part of its sustainability and energy-reduction strategy. Within the first year, the facility achieved:

• 10% average reduction in natural gas consumption
• More than 4 million cubic feet of natural gas saved annually
• Over $30,000 in annual energy cost savings
• Reduced carbon emissions associated with heating operations
• Project payback measured in months, not years

These results demonstrate how relatively low-cost operational improvements can deliver measurable sustainability gains while generating significant financial returns. Following the success of the initial installations, site leadership approved the expansion of Endotherm into additional closed-loop systems throughout the facility.

Why Facilities Choose Endotherm

Endotherm helps organizations achieve multiple objectives with a single solution:

• Lower energy costs through improved thermal efficiency and heat transfer
• Reduced natural gas consumption and associated greenhouse gas emissions
• Support for corporate sustainability and ESG initiatives
• Extended equipment life by reducing system workload
• Fast return on investment without major capital expenditures
• Greater resilience against energy price volatility

As sustainability goals become more aggressive and energy markets remain unpredictable, facilities are increasingly seeking practical solutions that deliver measurable results. Endotherm is one example of how Watertech helps organizations improve system performance, reduce operating costs, and make meaningful progress toward a more sustainable future.
