4 HolE Drying

Four Hole drying means there are two internal fan motors giving the opportunity to dry pressure neutrally.  Pressure neutral drying is by far the fastest way to dry with a dehumidifier alone.  Four-Hole dehumidifiers can always be used in “Three-Hole” model.  To understand more see here.

With much smaller duct sizes it is not only easier to transport and store ducting but it is much easier to handle on the drying job and easier to vent through outlets.

1/4 of the Physical Size

If a dehumidifier is less than 52 lbs it can be carried by one person meaning less transport costs and labour costs for restoration companies with the products transported to where they are needed.  

When not in use, storage space and truck space to transport are often prime considerations for contractors.

One Power Cord or Two?

The Dri-Eaz and Pheonix dehumidifiers have large power requirements.  Two power cords are used to overcome the 220V input power supply restrictions in most North American homes being on 110V (110V is often referred to as 115V because of voltage fluctuation). 

In Europe, using two power cords on the same electrical product is actually not allowed so we have taken this consideration as best practice , Ecor Pro uses only one power cord.  Easier to operate, safer and prepared for possible future tighter legislation in N. America dehumidifier design. 


Not only more “green” but of course more cost effective.   Calculating the amount of power needed to extract one pint of water is probably the most accurate benchmark or rather best test in terms of efficiency.

Ecor Pro has come out time and time again as best in test, not just in test labs but more importantly by customers considering moving to Ecor Pro dehumidifier models.
