28 years of excellence in manufacturing, specializing in the heat exchange tube sector.

Refrigeration heat exchange tubes are specifically manufactured for various refrigeration equipment, including cold storage units, heat pumps, compressed air dryers, ice machines, supermarket display cases, and refrigerated trucks. Different refrigeration applications impose distinct requirements on tube design and performance. Kenergy provides specialized solutions for three typical application scenarios:

Dry Expansion Evaporator Tubes – Internally Grooved Straight Tubes, designed for dry expansion evaporators where refrigerant evaporates inside the tube while water or secondary coolant flows outside. The internal groove structure achieves efficient heat transfer within a compact shell. Ideal for heat pump units, industrial chillers, and compressed air dryers. Our optimized groove profiles maintain a high heat transfer coefficient even under low refrigerant flow rates.

Heat Pump Evaporator Tubes – Designed for air-to-water and air-to-air heat pumps, these tubes must provide reliable evaporation efficiency under low ambient temperatures and withstand defrost cycle stresses. Kenergy's heat pump tubes feature optimized internal groove geometries that maintain efficient heat transfer within an evaporation temperature range of -10°C to +10°C, while offering strong pressure resistance and freeze-thaw durability. Compatible with R134a, R410A, R32, and R290 refrigerants.

Condensing Unit Tubes – Designed for small condensing units used in commercial refrigeration such as supermarket display cases, ice machines, and beverage coolers. These tubes prioritize compact size and reliable pressure handling. Kenergy offers small-diameter, uniform-wall tubes that enable compact condenser designs, helping customers reduce overall equipment footprint.
