Understanding Heat Transfer Fluids
Heat transfer fluids have two essential functions in industrial systems:
- Efficiently transferring heat in heating or cooling systems
- Protecting circuits against corrosion, scale formation, and freezing
The choice of fluid depends on several factors: target temperature range, usage environment (food, industrial, chemical, etc.), materials used in the installation, and specific HSE constraints.
MPG vs. MEG: Choosing the Right Technology
Clariant offers two main formulations for its Antifrogen® fluids: one based on mono-propylene glycol (MPG) – Antifrogen® L -, and the other based on mono-ethylene glycol (MEG) – Antifrogen® N. Each offers specific advantages, documented in the technical data sheets:
| Feature | Antifrogen® L (MPG) | Antifrogen® N (MEG) |
|---|---|---|
| Toxicity | Low, not classified as harmful – suitable for sensitive environments | Medium – for closed, controlled circuits |
| Temperature range | –30 °C to +150 °C | –50 °C to +150 °C |
| Biodegradability | Good | Moderate |
| FDA / HT1 compliance | Yes (indirect food contact) | No |
| Heat transfer efficiency | Slightly lower than MEG at same dilution | Excellent thermal conductivity |
| Recommended use | Data centers, pharma, food, electronics | Industrial plants, energy systems, HVAC |
🧪 Technical notes :
- MEG offers slightly higher thermal conductivity than MPG, making it more effective in high-load thermal circuits.
- MPG is preferred in sensitive environments for its low toxicity and regulatory compliance (HT1, USDA), especially in food and pharmaceutical sectors.
Focus on Antifrogen® N and L
Antifrogen® N – MEG-based thermal fluid
Antifrogen® N is an ethylene glycol (MEG) – based heat transfer fluid, designed for industrial thermal systems requiring high-performance heat exchange. It contains carefully selected corrosion inhibitors that protect circuit metals (steel, aluminum, copper, brass, etc.).
Ideal for heating and cooling systems in commercial buildings, production facilities, and energy infrastructure.
💡Available in a 34% dilution, optimized to balance thermal performance, freeze protection (down to approx. –20 °C), and cost-efficiency.
Antifrogen® L – MPG-based and non-toxic
Made from mono-propylene glycol, Antifrogen® L is a non-toxic fluid recommended for sensitive environments and installations near food, pharmaceutical, or electronic products.
It features excellent thermal stability, low toxicity, and improved biodegradability compared to MEG-based solutions. It also meets multiple international standards (FDA, USDA, HT1), ensuring compatibility with regulated applications.
💡 Offered in a 35% dilution, optimized for freeze protection without compromising thermal efficiency or material safety.
Optimize Your Dilution with the Clariant Calculator
Proper dilution is key to balancing performance and safety. Too low, and freezing risk increases. Too high, and heat transfer efficiency drops.
Clariant provides a free online technical calculator to help users fine-tune their needs with access to physical data on:
- Density
- Viscosity
- Specific heat capacity
- Thermal conductivity
- Vapor pressure
- BRIX curves
- Freezing points
Key Applications for Clariant Fluids
Antifrogen® fluids are used across many high-demand sectors where thermal regulation is critical to performance, safety, and system reliability:
1. Data center and electronic equipment cooling
In data centers, servers produce constant heat that must be evacuated safely and efficiently. Antifrogen® L, with low viscosity and low toxicity, is widely used in liquid cooling or indirect heat exchanger systems.
It also supports cooling of power electronics (charging stations, inverters, converters), where optimal heat management enhances lifespan and performance.
2. Industrial and commercial heating
In heating systems for industrial buildings or district heating, Antifrogen® N protects circuits from freezing while ensuring effective heat exchange. Its corrosion-inhibited formulation extends equipment life (boilers, pumps, heat exchangers) and reduces maintenance costs.
3. Renewable energy systems
Solar thermal, geothermal, and biomass installations require reliable fluids to operate under fluctuating temperatures and periods of stagnation. Clariant fluids offer exceptional stability and resistance, even under extreme thermal cycling.
4. Chemical, pharmaceutical, and food processing industries
Precise thermal control is crucial during fermentation, crystallization, chemical synthesis, or pasteurization. Antifrogen® L is preferred for its non-toxicity, HT1/FDA compliance, and suitability in critical production environments.
Environmental and Safety Considerations
Responsible Formulation
Clariant fluids are designed with eco-consciousness in mind. Antifrogen® L (MPG-based) is biodegradable, low in aquatic toxicity, and not classified as hazardous — ideal for environmentally regulated sites or ISO 14001-certified operations.
Antifrogen® N, although MEG-based, is free from borates, nitrites, amines, and phosphates — reducing its environmental and health impact.
Future Outlook & Innovation
The thermal fluids industry is evolving in response to:
- Tightening chemical regulations (REACH, CLP)
- Growing safety demands in critical sectors
- Digitization of monitoring and predictive maintenance systems
- Emergence of bio-based or low-GWP heat transfer solutions
Clariant is investing heavily in R&D to develop next-generation fluids that are more sustainable, efficient, and compliant with future regulations.
