Q.  The first question is, do I really need a heated air curtain?

A.  The answer is maybe not. your Mars Air Door effectively creates an efficient insulation barrier between two environments. It's approximately 80% - 90% efficient. It does so by creating a stiff blast of air blowing down from the unit towards the floor. this blast of air create an invisible barrier separating the two environments. If you have people working near or walking through this moving air, they may feel a breeze. This could cause a wind chill effect, similar to the cooling effects of a blowing fan during the summer. Adding a heated air curtain unit will minimize this effect and make for a comfortable and more productive work place for your employees and customers. Should your facility be located in a cold weather environment creating significant temperature differences between the outside versus the inside temperature, a Mars Air Door heated unit will significantly improve the work environment comfort level and help maintain consistent temperature control. In addition, it will reduce overall utility and maintenance costs by providing a more constant inside temperature. 

Q.  So I've decided that I need a heated unit, which one do I choose; gas, electric, hot water or steam?

A. The general rule of thumb is to choose the same type of heat used to heat your facility, however, there may be some exceptions. For example; should your facility be steam heated, but connecting to the steam lines is too far, inconvenient or too expensive, it may be more feasible to choose gas or electric. To assure installing the correct heating method and proper heating outputs for you, we highly recommend consulting with your friendly Mars factory representatives first for proper selection.
