Clariant Antifrogen L Food‑Grade Propylene Glycol Antifreeze Blue Heat‑Transfer Fluid for Food & Pharmaceutical Industrial Refrigeration and Heat‑Pump Systems

Full Name & Product Positioning Full product name: Clariant Antifrogen L Food‑Grade Propylene Glycol‑Based Heat‑Transfer Fluid (Antifreeze) Antifrogen L is a light‑blue transparent heat‑transfer fluid compounded from monopropylene glycol and a dedicated corrosion‑inhibitor package. It contains no nitrites, amines, borates, silicates or phosphates. Designed for closed‑loop refrigeration, heat‑pump and waste‑heat‑recovery systems in food and pharmaceutical industries, it delivers both antifreeze performance and long‑term metal corrosion protection. Suitable for closed circulating systems where accidental contact with food materials may occur. Core Technical Parameters Parameter Typical Value Product Type Propylene‑glycol‑based food‑grade heat‑transfer antifreeze Appearance Light‑blue transparent liquid Main Components Monopropylene glycol + dedicated phosphorus‑free corrosion‑inhibitor formulation Density (20 ℃) Approx. 1.043 g/cm³ pH (neat liquid) Approx. 8.5‑9.5 Flash Point Approx. 105 ℃ Boiling Point Approx. 187 ℃ Standard Packaging 220 kg iron drum Core Advantages (Based on performance under test conditions per original‑manufacturer TDS. Actual results vary with formulations and do not represent end‑use performance guarantees.) 1.  Free of nitrite, amine, boron, silicon and phosphorus additives; meets safety requirements for food and pharmaceutical industries and supported by toxicological risk‑assessment reports. 2.  Propylene‑glycol base features high boiling point and low evaporation loss for minimal consumption over long‑term system operation. 3.  Formulated with dedicated corrosion‑inhibitor components to provide long‑term anti‑corrosion protection for carbon steel, copper, aluminium and other system metals. 4.  Water‑miscible; can be diluted with water to achieve different freezing points, suitable for cooling‑and‑heating working conditions over a wide temperature range. 5.  Biodegradable and environmentally friendly; long service life in closed cooling systems, up to more than 20 years under cooling service conditions. Main Application Fields Core applications: Brine for food‑plant refrigeration, heat‑transfer fluid for pharmaceutical equipment, heat‑pump systems, cold storage, cooling circulating systems for ice‑cream / dairy / brewing processing. Suitable applications: Waste‑heat‑recovery units, food‑grade fire‑protection sprinkler circuits, cooling loops for aquatic‑product processing. Prohibited scenarios: Direct oral ingestion, open water pools, unsealed open liquid storage tanks, motor‑vehicle engine coolant.
