Release AHU Design v. 4.4.0 (2025-03-13)
HIGHLIGHTED NEWS
GOLD RX 80+ for Europe
GOLD RX 80+ is now available for calculation in AHU Design and ordering. Official SOP date is 31th of Mars.
To cover the flow rate gap between GOLD/SILVER C RX 080 and 100 we are now adding RX 070+ and 080+ to the range.
The new product is based on current RX 070 and 080 but equipped with a larger rotor section allowing higher airflow with maintained SFP and thermal efficiency.
In this project modifications are also done in the fan block for 070 and 080, giving less insert losses and due to that lower SFP. As much as 4-5% lower SFP at the same design point can be expected giving a performance boost also for the RX 070 and 080 without the new plus-size of rotor. Also CX are positively affected by the modifications.
Added Silver C constants into Technical Printout
Constants for Silver C is now available in Technical Printout under fan component
Demarcation printout for GOLD in Europe
Printout Demarcation list is now available in AHU Design for GOLD units. The printout is selectable in section Controlsystem.
New component tab in Design view for Hoods in AHU design
The number of components is increasing in AHU Design, to simplify the selection of components an new main tab for hoods is now available in Design view.
