What is the pressure drop across open and tubular/sheathed elements?
The pressure drop can be estimated by referring to the Pressure Drop Chart included in the technical notes document on our website. These values are under the guideline that the depth of the element frame is 10” (254mm).
What are the minimum recommended air flow values for open and tubular/sheathed elements?
It is recommended that the minimum air flow across the elements is 300 FPM (1.52 L/S) for open element heaters and 500 FPM (2.53 L/S) for tubular/sheathed elements.
