Kaltra releases the next Lightstream Evo: now with scroll compressors

Kaltra’s new Evo platform has been complemented by air-cooled chillers with scroll compressors that run on refrigerants R410a, R452b, and R454b. The units with refrigerant R32 are also expected to be available for orders in Q4 2024.

Introduced chillers offer cooling capacities from 250 to 1250kW (2 to 4 refrigeration circuits) and inherit all the advantages of the Evo platform, including twin-slab condenser coils with dedicated subcoolers, built-in sequence management, load-sharing functionality, and more.

Thanks to the twin-slab condenser architecture, the footprints and weights of Lightstream Scroll Evo series chillers have been significantly reduced, which has also resulted in a price reduction.

The whole range includes 64 base models and 512 modifications featuring two efficiency grades, four refrigerants, and various sound levels. Low-sound packages reduce sound pressure levels to 48dB(A) due to advanced soundproofing materials used for insulation. Operating range is -20ºC to 55ºC, making Lightstream Scroll Evo suitable for use in cold, temperate, and hot climates.

Users can configure Lightstream Scroll Evo with integrated hydronic kits, choosing from fixed- or variable-speed circulation pumps, buffer and expansion tanks, and related accessories. Fast restart, dual power supply, energy metering, refrigerant leak detection – among other options available for Lightstream Scroll Evo customers.

Highest energy efficiency of the lineup was confirmed by SEPR HT values of up to 6.15 and EERs of up to 4.52 (for subrange HS).

The equipment is designed for installation on power networks operating at a frequency of 50Hz.

Scroll-compressor chillers based on the brand-new Lightstream Evo platform offer remarkable energy efficiency, a selection of green refrigerants, a wide operating range, and quiet operation.
