The COOLSHIFT XL series is designed for large-scale projects with the highest demands – such as district heating networks, energy-intensive processes, or large building infrastructures. With heating capacities of up to 2 MW and cooling capacities of up to 1.5 MW, it delivers scalable performance at an industrial level. Thanks to parallel compression, a deep temperature range (down to -40 °C), and precise control, COOLSHIFT XL achieves impressive efficiency even under challenging operating conditions. The system can be configured to meet specific requirements and integrates seamlessly into higher-level energy systems (Modbus/SCADA).
