China Zt030 Coolsour Coaxial Coil Heat Exchanger

APPLICATIONS
Coaxial heat exchangers are used as evaporators or as condensers. They consist of one or more inner tubes and one outer tube. This tube bundle is coiled in a spiral shape and brazed at the ends with T-fittings.
TYPICAL APPLICATIONS
- Heat pumps for hot water
- Chillers
- Cascade heat exchangers in multistage refrigeration systems
- Temperature control units/climate chambers
- Air conditioning and heating in marine applications
BEST PERFORMANCE WITH OPTIMISED SURFACES
Coaxial heat exchangers, developed at our in-house thermal engineering laboratory, have inner tubes specially optimised for evaporation respectively condensation. This results in a much higher specific performance and a very compact and comparatively lightweight design.
COAXIAL EVAPORATORS
Coaxial evaporators are the preferred choice in applications where water needs to be cooled significantly. At the same time they also offer reliable superheating of the suction vapour, which is facilitated by the counter-flow layout. A low-noise operation is achieved by spacer rings in the jacket tube.
COAXIAL CONDENSERS
Coaxial condensers are normally used in applications which require high water temperatures in conjunction with the use of hot gaseous refrigerant. In counter-flow operation this is achieved with an optimised heat exchange. For a low-noise, non-vibration operation, dents are pressed into the jacket tube. Coaxial condensers offer excellent value for money.
