As energy prices continue to fluctuate and sustainability targets become more demanding, operators across the brewing and distilling sector are under pressure to improve efficiency without compromising product quality or production reliability.

This is where Hydratech is making a significant impact.

Through advanced thermal fluids, specialist additives & inhibitors, proactive fluid monitoring programs, and full system optimisation services, Hydratech is helping breweries and distilleries upgrade their cooling systems to achieve measurable reductions in energy consumption, maintenance costs, and carbon emissions.

Why Thermal Fluids Matter More Than Ever

Cooling systems are often overlooked as a source of inefficiency. Many facilities continue to rely on traditional propylene glycol solutions because they have long been considered the industry standard for food-safe cooling applications.

However, traditional glycol systems come with limitations.

Conventional propylene glycol fluids are inherently less efficient at transferring heat and become significantly more viscous at lower temperatures. This forces pumps to work harder and increases energy consumption throughout the entire cooling circuit. In high-demand brewing and distilling environments where chillers and pumps operate continuously, even small inefficiencies can translate into substantial operational costs over time.

Hydratech’s approach is based on a simple principle: improve the performance of the fluid itself, and the entire system becomes more efficient.

Advanced Heat Transfer Fluids Designed for Brewing and Distilling

Hydratech has developed a range of food-safe thermal fluids specifically engineered to optimise heat transfer performance in breweries, distilleries, and food and beverage facilities. The company’s flagship product, Coolflow DTX®, has become increasingly recognised across the industry as a next-generation alternative to conventional propylene glycol. Unlike standard glycol formulations, Coolflow DTX® is thermodynamically optimised to provide enhanced heat transfer while maintaining low-toxicity credentials suitable for food-safe environments.

The benefits are significant.

Coolflow DTX® can provide up to 15% lower energy consumption compared to traditional propylene glycol systems. The fluid’s lower viscosity reduces pumping energy requirements, while improved thermal conductivity enables more efficient heat exchange across the system.

For breweries and distilleries operating multiple fermentation vessels, maturation tanks, or process cooling loops, these efficiency gains can create major savings in electricity usage.

The company has also introduced Coolflow® MAX, a next-generation nano-particle thermal fluid designed to push efficiency even further. Coolflow® MAX has demonstrated additional energy reduction savings exceeding 10%.

These are not theoretical claims. Hydratech’s thermal fluids are already in use by recognised brewing and distilling brands including Molson Coors, Heineken, Camden Town Brewery, Glenmorangie, Diageo, and Beavertown. The technology has also seen adoption across wider food and beverage manufacturing, with companies such as PepsiCo, Coca-Cola, Haribo, Papa Johns, Walls, and McCain utilising Coolflow DTX® systems.

Beyond Fluids: The Importance of Additives and Inhibitors

While fluid performance is critical, maintaining the health of a cooling or heating system requires more than simply filling a system with glycol.

Over time, closed-loop systems can suffer from contamination, corrosion, fouling, microbiological growth, and chemical degradation. These issues reduce efficiency, increase maintenance costs, and can ultimately lead to unplanned downtime.

Hydratech manufactures specialist multi-function inhibitors and cleaning and sterilising chemicals specifically designed for industrial process cooling systems.

These additives play a vital role in protecting pipework, pumps, heat exchangers, and process equipment from internal corrosion and contamination.

For breweries and distilleries, this is particularly important because production continuity is essential. A cooling system failure during fermentation or storage can disrupt production schedules, damage product quality, and result in costly operational losses.

Hydratech’s inhibitors and conditioning solutions help operators maintain long-term system stability while preserving thermal efficiency.

In practical terms, cleaner systems transfer heat more effectively, require less pumping energy, and experience fewer maintenance-related shutdowns.

Fluid Monitoring Programmes That Protect Performance

One of the most overlooked causes of energy inefficiency in brewing and distilling is deteriorating fluid condition.

Even high-quality thermal fluids gradually degrade over time due to oxidation, contamination, dilution, and operational stress. Without regular monitoring, operators may not realise their systems are operating inefficiently until problems become severe.

To address this, Hydratech offers a dedicated Fluid Monitoring Program (FMP), providing proactive heat transfer fluid testing, analysis, and care for closed-loop cooling systems. The programme includes in-house laboratory chemical and microbiological testing, detailed analysis, and reporting.

Regular monitoring allows breweries and distilleries to identify issues before they escalate into major operational problems.

Verifying fluid condition helps enhance system performance, maximise production output, and avoid costly shutdowns caused by contamination or corrosion.

There is also a direct energy benefit.

Poor fluid condition can increase viscosity, reduce heat transfer capability, and force cooling equipment to work harder. Proactive fluid monitoring helps avoid unnecessary increases in operational energy costs while improving return on investment and reducing CO2 emissions.

For facilities focused on sustainability reporting and ESG targets, this type of proactive maintenance is becoming increasingly valuable.

Converting Existing Systems Without Major Disruption

Many breweries and distilleries assume that improving cooling system efficiency requires a complete infrastructure replacement.

Hydratech’s services are designed to avoid that scenario wherever possible.

The company specialises in upgrading and optimising existing systems, enabling operators to improve performance without major capital expenditure.

A major opportunity for many operators lies in retrofitting existing propylene glycol systems with Hydratech’s advanced Coolflow DTX® or Coolflow® MAX formulations.

For breweries and distilleries currently running conventional glycol systems, this provides a practical route to improving thermal performance and reducing energy consumption without the need for a full plant redesign.

Because Coolflow DTX® offers lower viscosity and enhanced heat transfer properties compared to standard propylene glycol, facilities can achieve measurable reductions in pumping energy and improved cooling efficiency using much of their existing infrastructure.

Hydratech supports these retrofit projects with comprehensive system cleaning, chemical conditioning, re-filling, balancing, and commissioning services.

This ensures the upgraded system is fully optimised from the outset, helping operators maximise both efficiency gains and long-term reliability.

With more than 25 years of experience, Hydratech also provides expert guidance on fluid formulations, concentration ratios, and compatibility considerations.

For breweries and distilleries that may have expanded incrementally over time with mixed infrastructure and ageing equipment, this expertise can be invaluable.

By retrofitting existing glycol systems rather than replacing them entirely, operators can unlock meaningful energy savings, improve process stability, and extend equipment lifespan — all while minimising operational disruption and capital investment.

System Energy Optimisation: Looking Beyond the Fluid

Hydratech’s philosophy extends beyond supplying fluids.

The company recognises that true efficiency improvements require a full-system perspective.

That is why Hydratech offers specialist System Energy Optimisation Services designed to identify and eliminate energy performance gaps across complex cooling and heating installations.

These services include full energy performance audits and measurement verification studies for closed-loop systems.

Hydratech also carries out advanced hydronic and thermodynamic optimisation using digital twin modelling, simulation, and analysis.

Digital twin technology enables operators to model how their systems behave under real operating conditions, helping identify inefficiencies that may otherwise remain hidden. This data-driven approach allows Hydratech to provide evidence-based ROI analysis supporting energy-saving recommendations.

The result is a clear engineering roadmap showing quantified impacts on energy consumption, operating costs, carbon emissions, and capital investment requirements.

For breweries and distilleries facing rising utility costs, these insights can support both operational decision-making and long-term investment planning.

Smaller Systems, Lower Capital Costs

One of the most compelling aspects of advanced thermal fluid technology is that efficiency improvements can influence system design itself.

Because Coolflow DTX® offers lower viscosity, better thermal conductivity, and greater density than traditional propylene glycol, systems can often achieve the same cooling capacity with smaller chillers, pumps, and pipework.

This creates opportunities not only for operational energy savings but also for reduced capital expenditure on new installations and facility expansions.

For growing breweries and distilleries planning future production increases, this can significantly improve project economics.

By improving overall system performance, Coolflow DTX® can also extend equipment lifespan, reduce maintenance requirements, and maintain more consistent cooling output.

In an industry where process stability directly affects product quality, consistency matters just as much as energy efficiency.

A Performance-Driven Future for Brewing and Distilling

The brewing and distilling industry is evolving rapidly.

Rising energy costs, sustainability pressures, and the need for operational resilience are forcing manufacturers to rethink traditional approaches to process cooling and heating.

Hydratech’s combination of advanced thermal fluids, specialist additives and inhibitors, proactive monitoring, and engineering optimisation services provides a practical pathway for breweries and distilleries to modernise existing infrastructure without unnecessary disruption.

Hydratech’s philosophy moves the industry away from legacy thinking towards a performance-driven approach to thermal fluid selection, monitoring, and maintenance.

For breweries and distilleries seeking to reduce energy usage, improve operational efficiency, lower maintenance costs, and support sustainability targets, that shift is becoming increasingly important.

In a market where every kilowatt matters and operational margins remain under pressure, smarter thermal management is no longer a niche engineering consideration.

It’s a competitive advantage.
