GERMANY: Kaltra has delivered an 800kW air-cooled chiller running on low GWP refrigerant R1234ze to an unnamed customer in Scotland.

The chiller from German manufacturer Kaltra’s Lightstream Screw Il range is equipped withBitzer screw compressors with stepless capacity regulation and advanced oil management. It is said to offer a SEPR HT value of 6.03 and EER as high as 4.11 at full load.

A twin-slab condenser optimises part-load performance and variable fan speed regulation enables precise condensation control, while airstream distribution system improves chiller efficiency under low-ambient conditions.

A proprietary dry-expansion evaporator in the single-pass arrangement features inner-grooved tubes and is fitted with baffles on the shell side to increase flow turbulence and overall heat transfer rates. 

Chiller operation can be controlled directly using an inbuilt touch-screen display or remotely by smartphone, tablet, or laptop using a wifi connection.
