New refrigerant
Now there is the new refrigerant R454B, which has a 78% lower GWP value than R410A and 31% lower than R32.
New rotor geometries with high efficiency
The unit sizes 1080, 1250, 1280, 1540 and 1550 have now been upgraded with new rotor geometries: R20, R30, R40, R50 and R60. These rotors reduce pressure drop while maintaining high efficiency.
Less energy-demanding fans
In our unit series for TOP 04 and Compact 04, we have implemented fans that require less energy. Which results in improved SFP value at lower air volumes.

Calculate energy saving and payback time
Under the Energy tab, you can now select Investment Calculation, a simplified and more straight forward version of our LCC and ROI calculations, more adapted to the format used among property owners. It provides a quick and easy way of calculating energy savings and payback times for AHU replacement projects. You can also get information about how the property value will be affected by the investment.
New rotor geometries with lower pressure drops
You can now select the full range of new rotor geometries R20–R60, also for the larger range of units, sizes 740, 850 and 980. You will have the same efficiency, but with a lower pressure drop.
More options to present technical data in printouts
Under Tools and Settings, you can in the default settings select if you want SEER, (Calculated Seasonal Efficiency Ratio) for an EcoCooler or a ThermoCooler HP during its cooling season operation, to be presented on your technical data.
New Zone control and updated flowchart layout
You can now select the new Zone control options, with better layout and presentation of the zones in the flowcharts.
