Atmospheric Water Generator

Engineering Design & Analysis

Johnston Engineering had the privilege to work with Dew Point Manufacturing on their cost-effective, sustainable, and eco-friendly solution to the world’s growing water shortage.


Dew Point Manufacturing has been reengineering residential and commercial Atmospheric Water Generating (AWG) products and will soon be launching the benchmark of AWG technology. Their Water Tower Series which includes their T40 (40 liter) and Countertop T20 (20 liter) units are going into mass production as of Sep 2016. They are very efficient, low maintenance, and of the highest quality – producing pure, clean, and chemical-free water.

Our Contribution:
