Protect your geothermal installation with high-quality inhibited glycol from Proviflow — engineered for optimal thermal performance, long-term corrosion protection, and sustainability.
inhibited glycol inside
When it comes to efficient, reliable thermal management, Proviflow’s inhibited glycol stands out as the smart choice. Specially engineered to deliver outstanding heat transfer performance while minimizing system wear, Proviflow ensures your operations run smoothly and sustainably.
optimal thermal efficiency
Proviflow’s precisely balanced inhibited glycol offer excellent thermal conductivity, maximizing system output across a wide temperature range.
corrosion prevention
Standard glycols can lead to corrosion and scale buildup within the geothermal system, reducing efficiency and increasing maintenance costs. Inhibited glycol contains advanced corrosion inhibitors that protect metal surfaces, including copper, aluminum, and steel, ensuring a longer lifespan for the pump and piping system.
freezing protection
During winter the heat transfer fluid goes from the inside pump into the ground, touching very cold environments. The Inhibited glycol prevents freezing in those sub-zero temperatures ensuring performance without the risk of ‘flokking’ in the fluid .
reduced maintenance and electricity costs
By preventing scale buildup, corrosion, and thermal degradation, inhibited glycol reduces the frequency of maintenance and fluid replacement. This leads in the long term to more lower electricity costs.
environmental and safety benefits
High-quality inhibited glycol formulations are designed to be environmentally friendly and biodegradable, reducing the impact on the surrounding ecosystem. Additionally, they are engineered to be non-toxic and safe for use in renewable energy applications.

Double interview in Cool & Comfort. Smeyers is one of the leading market players for more complex geothermal drillings that go hand in hand with the qualitative Proviflow HTFs for an optimal yield coefficient. Smeyers recently won the largest geothermal project in Belgium (2025); the BULA project in Bruges.

proviflow L
inhibited glycol inside
In Belgium and a lot of other regions, the law requires that coolants that are underground cannot be toxic.
That’s why we recommend proviflow L, an MPG-based glycol.
product highlights

longlife heat transfer fluids
the importance of corrosion inhibitors
All Proviflow fluids are tested to and exceed the ASTM1384-05 corrosion test standard. The range also contains a highly-advanced reserve alkalinity additive.
This ensures a longer and more efficient working life, limited disruption to processes, reduced maintenance costs and ultimately an improved return on capital employed.
All Proviflow products are designed and manufactured to the highest standards to give the end-user greater peace of mind in the knowledge that every product offers a long and efficient working life.
coloring heat transfer fluid can be useful!
what's your favorite color?
safety consideration - visual lead detection
A contrasting color of the HTF is the easiest way to have a visual leak detection control.
uniform color codes for your people in the field
If an internal color is linked to installation instructions, you can create a uniform color code that makes it very easy for your employees to communicate.
promotional consideration
Choose the color according to the company colors.
glycol with a service
smart services that make the difference
Although our product may be one of the best in the market, we believe that our smart services are what adds the extra value. Our people are the engine behind our services that makes the difference for you.
dedicated order fulfillment service
Not just an order number, or customer ID. Behind the scenes a team of professionals are handling your order with great care.
Once your order comes in, our in-house production team plans to get your product on time on the place where you need it.
That’s what we call flexibility.
volume as you wish
We understand that not every turbine has the same size. Or you don’t want to waste time during installation on ‘guessing’ if the turbine circuit is completely full.
That is why we offer proviflow in the receipient that suits you best at that moment.
analysis service
Proviflow’s lab offers a complete analysis service to help to determine the exact moment of your glycol maintenance.
With a sample, we examine the important parameters to check the condition of the heat transfer fluid.
No guesswork or estimates, the report with the accurate data gives you the exact number to intervene and bring the glycol HTF to it’s original specifications.
