zhongfu NO5 refrigerant, specifically optimized for low-temperature operating conditions, combining high energy efficiency with low-GWP characteristics, and widely suitable for demanding application scenarios such as commercial freezing and cold-chain logistics.

🧊 Selecting refrigerants for low-temperature applications | From No. 1 to No. 9, one always fits your system

For those working in low-temperature circulation, freezing, and cold-chain operations, what is the biggest concern?Choosing the wrong refrigerant——either the freezing point is not low enough, the piping is corroded, or the low specific heat capacity causes high energy consumption. Today we cover the full Zhongfu refrigerant seriesNo. 1 to No. 9in detail, so you can directly match the right option for low-temperature conditions👇

✨ Key highlights

• Full model coverage: From -100℃ cryogenic to +120℃ wide temperature range, food-grade contactable types and anhydrous types for hazardous processes are all available

• Efficient heat transfer, more stable performance: High specific heat, high thermal conductivity, low kinematic viscosity, fast cooling, low pumping power, and freezing point stability over the long term

• Maximum safety factor: Ultra-fine pre-film passivation + flame-retardant technology; non-corrosive to carbon steel, copper, and aluminum, non-volatile, non-flammable, and requiring less maintenance for greater peace of mind

✅ How to choose?For cold storage and cold-chain, choose models with a low freezing point and high specific heat; for ice and snow venues, choose those with a wide temperature range and high cold-storage capacityNo. 3; for hazardous synthesis conditions such as Grignard and Friedel-Crafts, use the anhydrous grade directlyNo. 5— no free water, non-explosive, superconducting-grade heat transfer; for food processing and immersion quick freezing, use food-contact grade. With the right choice, the system runs stably and energy consumption can also be reduced

From No. 1 to No. 9,Direct supply from source, consistent batches, the real challenge in low-temperature service—choose correctly the first time and avoid hassle.
