Advanced Inhibitor Package

ESSELTHERM PGL contains industrial-grade corrosion control inhibitors specially formulated to extend fluid service life and reduce maintenance needs. The inhibitor package includes:

  • Phosphate
  • Boron
  • Nitrite
  • Tolyltriazole (TTZ)

These inhibitors provide robust protection for both ferrous and non-ferrous metals such as brass, copper, copper alloys, steel, cast iron, and aluminum. By preventing corrosion, scaling, and other harmful fouling, the fluid ensures optimal system performance and longevity.

Key Benefits

  • Reduced Maintenance

    Advanced inhibitors offer a higher level of reserve alkalinity, resulting in fewer maintenance requirements through re-inhibiting.

  • Versatile Applications

    Ideal for demanding applications including HVAC systems, cold storage equipment, vapor recovery systems, and more.

  • Low Toxicity

    Being propylene glycol-based, ESSELTHERM PGL is less toxic than ethylene glycol coolants, making it safer for environments where human or environmental exposure is a concern.

What Is Propylene Glycol?

Propylene glycol is a synthetic organic compound with the chemical formula C₃H₈O₂. It is a colorless, odorless, and slightly viscous liquid that is hygroscopic and fully miscible with water. Due to its low toxicity and excellent heat transfer properties, propylene glycol is widely used in applications where safety and environmental considerations are paramount.

Food Grade Option: ESSELTHERM PGL-FG

For applications that require food-grade standards, we offer ESSELTHERM PGL-FG. This food grade propylene glycol variant is suitable for industries such as food processing and pharmaceuticals, where incidental contact with products may occur. It meets stringent safety regulations without compromising on performance.

Propylene Glycol in Antifreeze

Propylene glycol is a key component in many antifreeze formulations due to its ability to lower the freezing point of water. Unlike ethylene glycol, propylene glycol is less toxic, making it a safer alternative for applications where human or environmental exposure is a concern. Its use is often mandated by law in sensitive industries to ensure safety.

Environmental Responsibility

ESSELTHERM PGL is readily biodegradable and does not accumulate in water systems, minimizing environmental impact. However, large-scale contamination should be avoided as rapid oxygen depletion may occur, potentially affecting aquatic life.

Propylene Glycol Uses

  • Heat Transfer Fluid: Commonly used in heating, ventilation, and air conditioning (HVAC) systems for its efficient thermal conductivity.
  • Antifreeze Propylene Glycol: Acts as an antifreeze agent in cooling systems, preventing freezing in low-temperature environments.
  • Food Industry: Utilized as a food grade propylene glycol in food processing, pharmaceuticals, and cosmetics as a solvent, humectant, and preservative.
  • Industrial Applications: Employed in chemical manufacturing processes and as a base for producing unsaturated polyester resins.

Antifreeze Propylene Glycol vs. Ethylene Glycol

While both propylene glycol and ethylene glycol are used in antifreeze and coolant applications, there are important distinctions:

  • Toxicity: Propylene glycol is considerably less toxic than ethylene glycol, reducing health risks in case of accidental ingestion or exposure.
  • Environmental Impact: Propylene glycol is more environmentally friendly due to its biodegradability.
  • Performance: Ethylene glycol offers slightly better heat transfer efficiency, but propylene glycol's safety advantages often make it the preferred choice.

Understanding these differences is crucial for selecting the appropriate coolant for your system. ESSELTHERM PGL provides a balanced solution with excellent performance and enhanced safety.
