FAQs

What is a make-up air heater?
It supplies 100% outdoor air that is heated and evenly distributed indoors to maintain air quality and positive pressure during construction or industrial processes.

Can I run propane or natural gas?
Yes. The MA-550 is configured for either fuel. Verify correct jetting and supply pressure/regulators for the selected fuel.

Does it recycle indoor air?
No. Make-up air heaters draw 100% of their air from outdoors and temper it before supply. This helps manage moisture and contaminants.

  The spot coolers provided Climage Control Solutions saved the day at my office when our central ac went out in the entire building. The portable ac units kept us all very comfortable for several weeks while we waited for ours to be repaired. It only took 2 units to cool quite a large space. Thanks you CCS!!! We appreciate you!

  Climate Control Solutions was great to work with.  We had a order come in that required 12 Cool Space 400's asap.  They had the equipment in stock, paperwork was seamless, and equipment was ready for pick up when stated.  We will be buying more equipment from Climate Control Solutions in the future!
