Overdoor & Downflow Heaters

Why choose an air curtain or over door heater? 

If you're thinking about the best way to keep temperatures in check at doorways, going with an air curtain instead of a door heater has some clear benefits. Air curtains whip up a strong air barrier that keeps different environments separate, so you can keep the inside climate steady while leaving doors open. This is a big win for busy areas or larger entrances where managing the environment is key. On the other hand, door heaters mainly just warm things up, making them better for smaller entrances with less foot traffic. Air curtains are great because they help keep heated or cooled air in, cutting down on energy use and costs, plus they keep out dust, pollutants, and bugs. This makes them a smart, cost-effective option for businesses wanting to boost comfort without messing up efficiency.  

What is the difference between an air curtain and over door heater? 

Air curtains and over-door heaters often get lumped together, but they actually have different jobs when it comes to climate control in commercial and industrial spaces. Think of air curtains as an invisible shield of air over a doorway, keeping the indoor and outdoor environments separate. They help maintain the inside temperature by blocking outside air from sneaking in, which is super handy for doors that stay open for a long time.  

On the other hand, over-door heaters are all about warming the air right by an entryway, making it comfortable for folks coming in. They’re perfect for doors that are mostly closed since they focus more on heating rather than creating an air barrier. Both aim to boost comfort and save energy, but picking between an air curtain and an over-door heater really depends on what that entrance needs—like how often the door opens and the kind of temperature control you’re after.
