Twin-slab condenser coils bring efficiency advantages
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
To best meet the needs of different installations, condenser size can be customized, while multi-port microchannel tubes can be selected to meet capacity requirements.
Twin-slab coils can be ordered uncoated or with the electrophoretic coating (e-coating) with a UV-protecting topcoat.
Headquartered in Germany and Austria, Kaltra designs, develops, and manufactures air conditioning and refrigeration equipment and systems. The company offers air-cooled, water-cooled, and free cooling chillers, precision air conditioners, IT cooling systems, including room-, rack- and row-based solutions, and energy management solutions. It also designs and manufactures air-cooled condensers, dry coolers, and cooling units for special applications. Additionally, Kaltra offers microchannel heat exchangers for condenser, evaporator, and water cooling and heating applications, as well as aluminium coils for small cooling applications. All Kaltra products are engineered with the clear objective of improving energy efficiency and reducing total cost of ownership.
