Heat exchangers

In coaxial heat exchangers, fluids are ideally conducted in counter-flow directions. The Wieland WKE and WKC series have been optimized for the condensation or evaporation of refrigerants and are used in reciprocating chillers and heat pumps.

Your advantages at a glance

• High specific power due to optimized inner tubes
• Flow guidance in counterflow
• Insensitive to frost
• Low fouling tendency
• Long service life
• Reversible operation possible
• Standard designs from stock

WRK finned tube heat exchangers are suitable for efficient direct condensation and evaporation in heat pump buffer tanks. The inner grooved surface of the used finned tubes optimize the heat transfer. Thus highest COP-values are possible even with smallest temperature differences.

Your advantages at a glance

• Efficient: Highest COP values due to direct integration of the heat exchanger in the storage tank
• Filling volume optimized: Smallest refrigerant volumes due to compact design
• Easy handling: Easy replacement and maintenance

Hygienic and compact: Wieland Safety Heat Exchangers are ideal for the direct heating of water for domestic use by condensing the refrigerant within the tank. The double-walled model offers additional safety against contamination and complies with the guidelines for ensuring the quality of drinking water.

4 good reasons for the Wieland safety heat exchanger series

• Cost-effective | Benefit from higher performance with the lowest refrigerant and material consumption!
• Efficient | Achieve the highest COP values according to DIN EN 16147 by installing the heat exchanger directly in the storage tank.
• Safe | Rely on absolutely reliable media separation through double tubes
• Easy handling | Reduce your effort for installation and replacement.
