New Lightstream Turbo II subrange benefit high-lift applications
With the continuously rising demand for cooling in hot climate regions, low-temperature process applications, and heat recovery solutions, Kaltra had busied developing chillers for high temperature lift applications. Efforts were made towards the design of Turbocor-based air-cooled chillers as the most energy-efficient and environmentally sustainable solution.

At present, Kaltra launches its new Lightstream Turbo II HL range with an expanded operating map with a maximum saturated discharge temperature of as high as 70°C. With up to 4 Turbocor TTH/TGH series compressors on board, the range offers a nominal capacity rating of up to 1800kW without performance degradation over the life of the chiller thanks to oil-free, magnetic bearing technology. Hot water production is optionally available with either desuperheater (partial heat recovery) or condenser (full heat recovery).

Lightstream Turbo II HL chillers are available with either flooded or low-charge falling film evaporators.

New high-lift range chillers utilize A1 R134a, lower GWP R513a, and ultra-low GWP A2L refrigerant HFO-1234ze. With these chillers, Kaltra also introduces new control features ensuring adaptive response to cooling loads.

The range is suitable to operate up to 52˚C ambient temperature, can generate up to 50˚C hot water at 0˚C ambient and provides minimum saturation suction temperature of -18˚C.

Furthermore, we made available the models with a reduced radiated sound power level (-6dB(A) compared to standard units) and a lineup with enlarged condensers for higher operating efficiency.

New chillers are compliant with step two (Tier-2) of the Ecodesign Directive (EU) 2016/2281 challenging threshold of minimum seasonal efficiency and entered into force in January 2021.
