Kaltra extends the range of water-cooled chillers with inverter models and adds R513a

October 8, 2018

 

Kaltra is delighted to make an exciting new addition to their chiller portfolio – Powerstream Screw Inverter family of water-cooled chillers.

 

The chillers feature fixed-speed screw compressor combined with an inverter-driven one.  The unit starts with the inverter compressor; when the cooling demand exceeds its capacity, the second compressor starts up at full speed to ensure the best possible efficiency. Capacity regulation is carried out by the inverter-driven compressor.

 

The new inverter chillers maintain the industry-leading efficiency levels and demonstrate the average ESEER value of 8.52.

 

In total, 20 models were added, ranging by capacity from 500 to 1800kW. All units can operate with either R1234ze, or R134a, or R513a refrigerant. The refrigerant R513a is a mixture of R1234yf and R134a gases with a low GWP value of 570. It carries the ASHRAE flammability classification of A1. Options include a condensation control system, economizers, and advanced controls with comprehensive diagnostic functionality.

 

Chillers have been engineered to fulfill the customers’ demand on raising the bar on energy efficiency and reducing the climate-change impact.

 

Powerstream Screw Inverter chillers will be available for orders this month.
