Heat Transfer Oils – Reliable Energy Transfer in Industrial Systems

High-Quality Oils and Synthetic Fluids for Stable and Safe Operation

At M&M Intercom, we supply premium heat transfer oils designed for efficient transfer of thermal energy in closed heating and industrial systems. Properly selected heat transfer oil supports stable operation, accurate temperature control and long system service life.

Our range includes trusted brands such as Addinol, NSL, Orlen, FRAGOL, Aimol and BIONA, offering high thermal stability, oxidation resistance and minimal deposit formation. Various packaging options are available – from 10L and 20L canisters to 200L, 205L drums and 1000L IBC containers.

What Heat Transfer Oils Are and How They Work

Heat transfer oils are specially formulated industrial oils designed to transfer heat from a source (boilers, heaters) to a consumer (reactors, heat exchangers, dryers or process systems). They are used in closed and open systems, ensuring uniform heat transfer without direct contact between the heating medium and the product.

Main advantages include:

• high thermal stability
• low volatility
• resistance to degradation
• reduced carbon deposit formation
• long service life

Proper selection reduces the risk of overheating, oxidation and system blockage.

Types of Heat Transfer Oils in Our Range

Different formulations are available to match various temperature ranges and system requirements.

NSL THERM POWER 32 and 46 are high-quality mineral heat transfer oils suitable for closed systems operating at moderate to higher temperatures.

ADDINOL Heat Transfer Oil XW 15 and XW 30 M 250 are formulated for long-term stability and reliable performance at elevated operating temperatures.

For specific applications in the food industry, NSF-certified heat transfer oils such as FRAGOL FRAGOLTHERM FG-35 are available.

ISO and DIN Standards – Key Quality Indicators

Our heat transfer oils comply with standards such as ISO 30, ISO 32 and DIN 51522, ensuring conformity with international technical requirements.

Standardized viscosity, such as 22.5 mm²/s at 40°C, supports predictable performance and optimal oil circulation within the system.

Selecting the correct ISO viscosity grade is essential for:

• efficient circulation
• optimal heat transfer
• reduced pump wear
• long-term system stability

Thermal Stability and Oxidation Resistance

A key characteristic of quality heat transfer oils is thermal stability. At elevated temperatures, the oil must maintain its properties without forming carbon deposits or degrading its molecular structure.

High-quality formulations provide:

• lower maintenance costs
• extended oil change intervals
• stable viscosity
• minimal degradation

This results in reduced production downtime and improved energy efficiency.

Applications of Heat Transfer Oils in Industry

Heat transfer oils are used in:

• pharmaceutical industry
• food processing industry
• chemical industry
• plastics industry
• textile industry
• energy sector
• process reactor heating systems
• mold heating systems

Their adaptability supports reliable operation in closed systems with elevated operating temperatures.

Packaging and Logistical Flexibility

Different systems require different oil volumes. We therefore offer:

• 10L and 20L canisters for smaller systems
• 200L and 205L drums for industrial use
• 1000L IBC containers for larger installations

This ensures optimal supply according to system requirements.

Frequently Asked Questions About Heat Transfer Oils

1. What are heat transfer oils and where are they used?
Heat transfer oils are specialized industrial oils designed to transfer thermal energy in closed systems. They are used in heating systems, reactors, heat exchangers, dryers, mold systems and other process applications requiring controlled heat transfer without direct contact between the heating source and the product.

 

2. What is the difference between mineral and synthetic heat transfer oils?
Mineral heat transfer oils are suitable for moderate temperature ranges and provide a cost-effective solution. Synthetic oils support higher operating temperatures, improved oxidation stability and longer service life. Selection depends on maximum system temperature and operating conditions.

 

3. How to select the correct viscosity grade (ISO 30, ISO 32)?
Viscosity affects oil circulation and heat transfer efficiency. ISO 30 and ISO 32 indicate viscosity class at 40°C. Proper selection supports optimal pumping performance, reduced pump wear and stable system operation. Equipment manufacturer recommendations should always be considered.

 

4. What is the operating temperature range of heat transfer oils?
The temperature range depends on formulation. Most quality heat transfer oils operate reliably within a wide temperature range; however, the manufacturer’s maximum recommended temperature must not be exceeded. Excessive temperatures may lead to oxidation, degradation and carbon deposit formation.

 

5. How often should heat transfer oil be replaced?
Replacement intervals depend on operating temperature, oxygen exposure, contamination and oil quality. Regular oil analysis enables monitoring of oxidation, viscosity and impurity levels. With proper maintenance, quality heat transfer oils can operate for several years.

 

6. What causes degradation of heat transfer oil?
Common causes include excessive temperature, air exposure (oxidation), contamination and improperly dimensioned systems. Degradation results in increased viscosity, deposit formation and reduced heat transfer efficiency.

 

7. Are there heat transfer oils for the food industry?
Yes. NSF-certified heat transfer oils are available for applications where incidental food contact may occur. These oils comply with strict regulatory requirements and are suitable for use in food processing environments.

 

8. How does oil quality affect system energy efficiency?
High-quality heat transfer oils maintain stable viscosity, reduce deposit formation and improve energy transfer. This leads to lower energy consumption, reduced heat losses and extended equipment service life.

 

9. Can different heat transfer oils be mixed?
Mixing different formulations is not recommended without prior compatibility verification. Different additive packages and base oils may react, affecting system stability and performance. Before changeover, the system should be drained and, if necessary, cleaned.

 

10. How should heat transfer oil be properly stored?
Heat transfer oils should be stored in a dry, cool area protected from direct sunlight. Packaging must remain tightly sealed to prevent contamination with moisture or dust. Proper storage extends shelf life and preserves product quality.
