Kaltra has launched new twin-slab microchannel condenser coils that maximize performance and efficiency in air-to-refrigerant applications. Previously employed and evaluated in Kaltra air-cooled chillers, this solution achieved superior performance results and is now available for end customers and OEMs.
New condenser is specifically dimensioned for use in air-cooled chillers and includes an outer, thin-core subcooler coil and an inner condensing coil brazed integrally, with tube interconnections. Twin-slab condensers are available in single- and two-pass configurations and working pressures of 32 and 45 bar, depending on application requirements. Both versions feature same-side refrigerant connections and a coated steel frame with necessary sealings.
Owing to a higher degree of subcooling, twin-slab condensers deliver up to 25% more heat rejection compared to a traditional solution with the same fan airflow, at the same time improving system COP.
Suitable for HFC, natural, and low-GWP HFO refrigerants, twin-slab condensers are exceptionally efficient for refrigerants with the small latent heat of vaporization.
Twin-slab microchannel condensers offer several tangible benefits:
- Increase in condenser capacity
- Improve compressor efficiency (COP)
- Lower fan noise power without reduction in capacity
- Reduce initial system cost
Twin-slab coils can be ordered uncoated or with the electrophoretic coating (e-coating) with a UV-protecting topcoat.
