Run your business

Efficiently

We turn humidity into pure water while cutting energy costs for climate control.

Company Overview

WaHa has created an energy-efficient desiccant regeneration engine that both creates pure water and manages humidity using a wide variety of solid desiccants from silica gel and SAPO-34, to water harvesting MOFs. Our unique value proposition to improve energy efficiency is to improve heat pump efficiency by harvesting water instead of rejecting humidity.
