Frequently asked questions
What is the difference between PUR and EPDM?
According to the manufacturer, the PUR membranes have a wider operating range (normal operation 3–8 Nm³/(h·m Aer.)) and withstand −40 to +90 °C (Pre-PUR 602 only up to +60 °C), while the EPDM membranes have normal operation 6–8 Nm³/(h·m Aer.) and withstand 0 to +85 °C.
