Common calculation questions
Can I access prices for the coils I’ve calculated?
- Yeps! On the “Project processing” screen, simply check one or more coils and select price or offer checked.
- Price will provide you with the unit price if you order the coils one at a time.
- Offer checked takes into account all the coils you have checked and provides a price for if you order all the coils together as a consolidated delivery.
- The prices you see are based on who you are and any discount agreements you may have with us.
How can I run alternative calculations?
If you want to run alternative calculations on a locked coil, check the box marked “max. calculation”.

Is it possible to calculate DX coils in several steps?
This is not yet possible, unfortunately, but we’re working on it. Contact a member of our sales staff, who will be happy to help you.
Can I access DXF files for the coils?
But of course – no problem. Check the coil on the “Project processing” screen and then click “DXF – 3D”.
Can I cut out data for the coil I’ve calculated?
Certainly. Click “Description” and this will copy all data for the coil to the clipboard. You can then paste it in wherever you need it.
How do I select the fluid temperature for the heating drop in a combi-coil?
When the program calculates combi-coils, it uses the same flow in the heating drop as in the cooling drop. The fluid temperatures will therefore be the ones needed to handle the heating drop you have entered on the air side.
