Evaporator Fan Comparison
Hi guys,
I have a question in regard to the selection of the evaporator fan. Currently, we are using the Ziehl-ebm 350mm, axial flow fan, however we are now considering the alternative fan offered by Rotomatika, 350mm because of the cheaper price they offer. Rotomatika also claims that their performance was better than Ziehl during their manufacture testing. This all sounds good right?
Unfortunately, during our independent lab testing, we found that Ziehl was a significant better fan for our own coil blocks (6 Fins per inch) and the perforamnce was better by around 7-8%. So, I need some advice on this, should I go for what the Rotomatika clamied or should I trust on our lab test as our lab test might not be very accurate.
Also, I would like to hear people who have actually come across with Rotomatika and how did you guys think about it ?
Rotomatika : R11-axial Ventilator 350
Ziehl-ebm : s4E350-AP06-48
Thanks !
