The new Microchannel Evaporator

Microchannel evaporator: Decide in favor of greater efficiency and reliability

With our new innovative microchannel evaporator for cooling oil and emulsion your processes will get even more efficient:

  • Higher efficiency, lower operating costs
  • Simple maintenance and fast service
  • Trouble-free operation
  • Environmentally friendly

Thanks to a great number of small microchannels, its heat-exchanging surface is significantly larger than that of conventional evaporators. This leads to even more efficiency in cooling the oil and emulsion in your system. With our innovative microchannel evaporator, you will require significantly less refrigerant as well.

For our HYFRA Alpha and HYFRA Gamma product families, the microchannel evaporator is available in the 5-16 kW performance class with immediate effect.

  • An increase in the heat-exchanging surface creates more inflow surface. The medium’s direction of flow is used optimally.
  • In the evaporator, refrigerant consumption is reduced by up to 60%, which means savings in refrigerant procurement.
Maintenance & Service
  • Innovative cleaning concepts reduce the effort involved by up to 90%. Long chiller downtime is a thing of the past.
Trouble-free operation
  • Reduction in the risk of leakage thanks to the innovative design of the various evaporator solutions.
  • Corrosion-resistant coating.
Environmentally friendly
  • Reduced use of refrigerant helps to avoid greenhouse gas emissions and improves your ecological footprint.

The Microchannel Evaporator Principle

The large number of small μ channels (shown in blue) provides a significantly larger heat-exchanging surface than that of conventional evaporators. The sinus wave/fins (light gray area) which control the temperature of the emulsion or oil in the cycle, are cooled much more quickly. This makes the evaporation process more efficient. The small capillary diameter also requires significantly less refrigerant. From the very beginning, the 2-pass system of refrigerant distribution creates balanced refrigerant gas speed without negatively impacting gas pressure, which translates into even greater efficiency. The coating of the Microchannel also leads into higher resistance to chemical influences and prevents corrosion. 

Continuous cooler HYFRA Alpha

  • Cooling capacity from 5 to 16 kW
  • Maintenance and cleaning are done by simply opening the pot evaporator
  • An even faster cleaning is possible by the backwash function via the patented 4-way valve (optional), without disassembling the evaporator
  • Reduction of negative sludge accumulation in the evaporator by up to 95%.

HYFRA Gamma immersion cooler

  • Cooling capacity from 5 to 16 kW
  • Faster cleaning of the evaporator due to easy removal of the cooler from the tank
  • Reduction of leakage risk by eliminating more than 85 % of conventional solder joints
  • Flexible application even with more heavily contaminated media due to the innovative fin design
