Flooded Evaporators – Highest Efficiencies With the Lowest Refrigerant Charge

 

Wieland flooded evaporators are designed for industrial cooling applications requiring high thermal performance, low refrigerant charge and reliable operation over time. The complete range combines advanced heat exchange tubes, optimized refrigerant distribution and integrated internal heat exchange for high superheat and subcooling.

 

  • High thermal efficiency
     
  • Low refrigerant charge
     
  • Reliable operation
  • Flexible system design
     
  • Service-friendly maintenance
     
  • Compact solutions available

 

Product Variants

 

Depending on the system design, Wieland flooded evaporators and compact heat exchangers are available with different connection, operation and accessory options.

Standard Flooded Evaporators

 

In flooded evaporators, the refrigerant evaporates outside the tubes. Internally and externally finned heat exchange tubes, combined with optimized refrigerant distribution at the evaporator inlet and suction side, support very high thermal efficiency.

Compact CSF and CCF Heat Exchangers

 

Compact CSF and CCF heat exchangers are designed for water-condensed refrigeration units where high efficiency, compact dimensions and service-friendly maintenance are required. Their modular configuration supports redundancy or capacity increase, while the small footprint makes them suitable for installations with limited space.
