•
No current on coil surface
•
Lower temperature on coil surface in comparison to old type of electric heaters (for
ex. electric wires), long life solution
•
Large space of PTC coil, enhanced energy exchange between coil and air.
• Fully automated regulation of heat capacity depending on air flow
•
No risk of system overheat, thanks to „self cooling” option (coil automatically decreas-
es the temperature and heat capacity when air flow goes down)
•
Very low energy consumption
ACR Pro
industrial air curtians are equipped with modern and safe solution based on PTC electric heaters.
PTC are thermistors which means that along with the temperature increase the resistance of the heating element increases as well.
Thanks to that feature there is no the risk of overheating which lead to safer devices with more efficient performances. An additional
benefit is the lack of current on the heaters surface as well as larger energy exchange surface.
