Lightstream Screw II air-cooled chiller

Lightstream Screw II air-cooled chiller

Kaltra has overhauled its screw-compressor chillers to deliver higher operational efficiency with the new Lightstream Screw II range. Improvements include the latest screw compressors by Bitzer with smooth capacity regulation, redesigned refrigeration circuit, and evaporators.

The new ErP 2021 (Tier-2) compliant range delivers 250 to 1850kW cooling with an energy efficiency of up to 3.56 for 7/12° water and 35°C ambient air. Seasonal efficiency (ESEER) is as high as 4.89.

With four refrigerants available, of which three are lower GWP (R513a, R450a, and HFO-1234ze), Lightstream Screw II air-cooled chiller is also a solution addressing environmental sustainability. Further, the range offers improved sound performance and is also smaller in footprint compared to predecessor models. As with earlier models, the new units are equipped with Kaltra’s low-volume microchannel condenser coils contributing to less refrigerant charge.

The first orders are already signed for Lightstream Screw II chillers running on HFO-1234ze to be supplied in Scandinavia this month.

Air-cooled models with variable-speed screw compressors will be available in Q2 2021.

Max-Reger-Straße 44, 90571 Schwaig, Germany

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.

Kaltra intends to adopt R515b for its water chillers
The development of environmentally friendly refrigerants for air conditioning and refrigeration equipment is imperative to the growth of HVAC technology. The low-GWP refrigerants like R1234ze are promising candidates for replacing HFC refrigerants. However, these refrigerants are flammable. To address the flammability issue, Honeywell developed Solstice® N15, a non-flammable HFO blend. Currently, R515b has been confirmed for both compact screw and centrifugal Turbocor compressors. Realizing the immense potential of R515b, Kaltra has
Kaltra to modernize its air-cooled Turbocor chiller range
Kaltra, the specialist in air-conditioning and heat transfer technologies, modernized its Turbocor compressor-based chillers with air-cooled condensers and presents performance highlights of the series. The Lightstream Turbo II series is a unique development in the field of demand-responsive chillers, specially designed for variable-load cooling and optimized for the novel lower-GWP refrigerants R1234ze and R513a. The series is provided with the Turbocor compressor technology enabling cooling capacity control and resultant optimal energy use
Kaltra introduces modular precision air conditioners
Lambda CW II is the result of an extensive R&D process, with Kaltra utilizing microchannel coil technology to give new ranges their own unique properties for precision cooling. The new series comprises 24 models of modular precision air conditioners with chilled water as a cooling source and capacities from 65 to 290kW, available in upflow and downflow configurations. Reduced footprint of the Lambda CW II series offers cooling densities as high
