DER?Z Antifreeze: Antifreeze and Corrosion Inhibitor Heat Transfer Fluid for Closed Circuit Heating-Cooling Systems
The Importance of Using Antifreeze in Water Conditioning
Water conditioning processes are crucial for ensuring the most efficient use of water in heating and cooling systems. Especially in regions where there is a risk of freezing, antifreeze solutions are employed to prevent the liquid used in systems from freezing. Antifreeze not only lowers freezing points but also prevents corrosion and scaling in heating and cooling systems, extending their lifespan.
One of the prominent antifreeze products in water conditioning solutions is the DER?Z series produced by Deren Kimya. This series offers comprehensive solutions to ensure the smooth operation of systems.
DER?Z
DER?Z ensures safe operation in heating and cooling systems by lowering the freezing points of water. It is also known for its ability to protect system components at high temperatures and its resistance to corrosion. The DER?Z series products provide long-term solutions against potential corrosion, wear, and leaks in systems while offering energy-saving advantages. The products are certified with TS EN ISO 9001 and TS EN ISO 14001, and they fully comply with the International ASTM D1384 Standard. These certifications demonstrate that the products meet high standards of quality and environmental sustainability. Supported by a local product certificate, DER?Z products hold significant importance in Turkey’s manufacturing processes.
With various formulations adapted for different industrial and commercial applications, the DER?Z series has a wide range of uses. It primarily consists of two products:
DER?Z 9551: Reliable Protection for Industrial Systems
DER?Z 9551 stands out as a powerful heat transfer fluid used in industrial cooling and heating systems. This product offers high resistance to freezing and corrosion, protecting materials like copper, steel, and aluminum from scaling and corrosion. DER?Z 9551 can be safely used in heat transfer systems at temperatures ranging from -48°C to +140°C, particularly reducing maintenance costs for industrial equipment and providing long-term savings.
DER?Z 9666: Reliable Solution for the Food and Pharmaceutical Sectors
Specifically developed for use in the food and pharmaceutical sectors, DER?Z 9666 stands out for its compliance with health standards and its biodegradable composition. Thanks to its eco-friendly properties, this product does not harm the environment and performs effectively between -51°C and +170°C. Its usability in processes requiring food safety makes DER?Z 9666 one of the most reliable heat transfer fluids in this field.
Areas of Use for DER?Z
When used initially in newly constructed facilities, DER?Z prevents the corrosion of systems and heat sources, thereby extending the system’s lifespan. Additionally, it reduces maintenance and repair costs, contributing to fuel savings.
Hot Water Heating Systems
DER?Z stands out in closed hot water heating systems with its freezing protection and corrosion-inhibiting properties. Particularly in structures that are not regularly heated (such as holiday resorts, schools, and public institutions), it allows for significant energy savings by enabling the system to be turned off and restarted without issues. Furthermore, successful results have been achieved even in challenging conditions, such as underfloor heating with plastic pipe combinations or outdoor piping systems.
Solar Heating Systems
DER?Z exhibits the same effect in solar heating systems, providing at least two years of corrosion protection according to the DIN 4757 standard. The system’s performance should be measured every two years, and the DER?Z/WATER mixture should be replenished accordingly to ensure protection from corrosion and long-term durability.

Cooling Systems
DER?Z serves a dual function in cooling systems: it remains liquid while also protecting the system from corrosion. Particularly in systems where salt-based (alkaline) coolants were previously used, it is recommended to thoroughly clean the system before applying DER?Z. Otherwise, residues may diminish the corrosion-inhibiting property of DER?Z.
Application of DER?Z Products
DER?Z is a corrosion and freeze-inhibiting fluid developed for heat transfer and cooling processes. With a low evaporation loss rate, DER?Z is designed for a mixture with water that has a freezing resistance of up to -32.0 °C, suitable for the climatic conditions of Central and Eastern Anatolia. As the mixture approaches the freezing point, no separation occurs, thus preventing piping from bursting. Even with long-term use, the freezing resistance of the mixture remains unchanged, and its concentration stays stable.
It has been proven that the circulation pumps used in heating systems operate smoothly with DER?Z. However, when DER?Z is applied to systems previously using salt-based coolants, the rust-removal property may activate, revealing existing corrosion damage. This facilitates the identification of weak points in the system.
An important point to note during applications with DER?Z is that systems should be filled only with the DER?Z/WATER mixture; they should not be mixed with other products.
The recommended ratio for using DER?Z products varies according to the (-) protection value per cubic meter. The existing fluids must be cleaned before application. Flushing or rinsing with water is a critical step in the de-corrosion process. To benefit from the effective performance of DER?Z, the mixture should not be less than 20% by volume.
DER?Z can be mixed with water in any ratio; however, it is recommended to add it after filling two-thirds of the system with water using the circulation pump. A homogeneous mixture is achieved as the system operates, which may take several days.
Health, Environment and Storage Conditions
The DER?Z series is also notable for its eco-friendly properties. The product is classified as a low-level pollutant (WHC1) on the water pollutants list, indicating that it does not harm aquatic ecosystems. Its recyclable structure proves that DER?Z is an environmentally conscious product. Concentrations of DER?Z do not exhibit acute harmful effects on fish and bacteria at levels up to 1000 mg/lt.
In case of accidental ingestion, immediate medical attention should be sought. DER?Z contains no amines and has no flash point, making it safe for health.
It is essential to store and preserve the products under suitable conditions. When stored correctly, DER?Z complies with occupational health and safety requirements and does not have any adverse environmental impacts.
Conclusion
With its high performance and long-lasting protection in the field of water conditioning and antifreeze solutions, DER?Z has become an indispensable product in both heating and cooling systems. Its corrosion-inhibiting structure, energy-saving capabilities, and eco-friendly features provide a wide range of applications in industrial and commercial settings. When used correctly, DER?Z series products enhance system efficiency while reducing maintenance costs and safeguarding environmental safety, offering both economic and sustainable benefits to businesses in the long run.
