Evaporator Tubes

Evaporator tubes are specifically designed to efficiently boil process fluids on the outside surface of the tube, making them a key component in chiller evaporators and heat exchanger systems. During operation, the boiling of refrigerant on the tube exterior absorbs heat from the fluid flowing inside the tube, creating rapid and efficient cooling.

  • Efficient boiling on tube exterior
  • Porous finned surfaces for improved refrigerant evaporation
  • Internal enhancements that induce fluid rotation
  • Higher pressure drop for improved heat transfer
  • Increased system efficiency and cooling capacity
  • Improve Heat Exchanger Efficiency

Our products find applications across various sectors:

  • Chiller evaporators
  • Comfort cooling systems
  • Industrial process cooling
  • Ammonia chiller systems
  • Heat exchangers and refrigeration equipment

Available configurations include:

  • Prime surface (smooth) evaporator tubes
  • Externally finned tubes for enhanced boiling performance
  • Internally enhanced tubes with I.D. rifling or grooving
  • Internally & externally enhanced tubes for maximum heat transfer

Replacement evaporator tubes are available in a wide range of materials, including:

  • Copper and copper alloys
  • Copper-nickel alloys
  • Stainless steel
  • Carbon steel
  • Other custom alloys upon request

Overall evaporator and heat exchanger performance can often be improved by:

  • Increasing fins per inch (FPI) on externally enhanced tubes
  • Applying internal rifling grooves to increase surface area and pressure drop

These enhancements help retain fluids in the tube longer, resulting in higher heat transfer rates without major system redesign.

This design is widely used in comfort cooling and industrial process cooling applications, depending on the specific chiller configuration and operating requirements.
