Environment-friendly R1234ze chillers with oil-free centrifugal compressors

The Lightstream Turbo chiller family has been designed with attention to every detail to maximize operational reliability. It is ideally suited to the requirements of mission-critical applications like data centers, telecom facilities and clean rooms, and in every area where reliability is a crucial factor.

Due to its excellent efficiency at part-load conditions, the Lighstream Turbo chiller is a brilliant economy solution for applications where the heat load is not constant or expected to increase.

Lightstream Turbo chillers feature several key advantages:

• Class A energy efficiency with EER up to 3.76
• Compact and lightweight two-staged centrifugal oil-free compressors with built-in variable frequency drive deliver high efficiency at full load and extraordinarily high efficiency at part-load conditions. Lightstream Turbo operates with low-GWP R1234ze refrigerant, which takes environmental leadership while achieving the best energy performance levels
• New intelligent fan system consisting of the profiled, sickle-shaped axial fans, multifunctional air guide vanes, and diffusers – provides maximum flexibility, lowest possible sound emission, and highest energy efficiency
• All-aluminium microchannel condensing coils allows a number of advantages to be achieved, including low airside pressure drops, higher heat transfer rate, and closer approach temperatures
• Flooded evaporators enable chiller to operate at the higher saturated evaporating temperature when compared to many other types of evaporators and allows a higher cooling capacity to be achieved with correspondingly higher efficiency
• Utilizing low ambient air temperatures with free cooling coil

Lightstream Turbo chillers lineup includes 20 models with 280-1350kW capacities and a vast array of options and accessories.
