Hi E Dry Dehumidifier
Company Background


The HI E Dry dehumidifier is manufactured by the Therma-Stor company located in Madison, Wisconsin. The company was founded in 1977 and its first products were heat recovery water heaters.


A little later it began production of the Santa Fe range of free standing dehumidifiers for basements and crawl spaces and the Ultra-Aire range of ducted and installed whole house units. It also supplies water damage restoration models under the Phoenix Brand and the HI-E Dry line for commercial applications and swimming pools.


Therma-Stor products are renowned for their energy efficiency and effectiveness across a range of temperature conditions and the HI E Dry Brand contributes to that reputation.


The HI-E Dry range includes the following models.




The HI-E Dry 100

  • The Therma-Stor HI-E Dry 100 is a powerful and energy efficient unit which is designed for effective operation in a range of commercial applications, including swimming pools.
  • Capable of removing a little over 100 pints of water per day the HI-E Dry 100 will manage humidity effectively in areas of up to 2500 square feet.
  • Hi E Dry 100

  • The HI-E Dry 100 is a versatile appliance which can work well across a broad range of temperatures from 33°F to 110°F (1-43°C).
  • The HI-E Dry 100 may be used as a stand-alone unit or may also be ducted to enable it to operate outside the drying area or to control moisture in several smaller enclosed areas.
  • Although designed primarily for commercial operators some house-holders with a large, cold basement may wish to consider the 100 as an alternative to other basement models for use in their home.

The HI-E Dry 195

  • The Therma-Stor HI-E Dry 195 shares the features and capabilities of the HI-E Dry 100 and is designed for similar applications.
  • The HI-E Dry 195 is a much more powerful unit with almost double the water extraction capacity of the HI-E Dry 100 and is suitable for much larger areas, up to 5000 square feet in size.
  • The 195 achieves excellent energy efficiency which is largely achieved by pre-cooling the ambient air before it passes over the evaporator coils. This is similar to the "low grain refrigerant" technology used in restoration units and allows a greater degree of dryness to be achieved in addition to the energy savings.
  • Hi E Dry 195

  • A useful feature of the HI-E Dry 195 is an internal condensate pump with sufficient power to achieve 17 feet vertical lift. This feature allows greater flexibility to operators when selecting a discreet and convenient location for the unit.

The HI-E Dry Vehere

  • The Therma-Stor HI-E Dry Vehere is broadly similar to the HI-E Dry 195 although it lacks an integral pump to dispose of the condensate.
  • The HI-E Dry Vehere is optimized for use in swimming pools in which floor drainage is usually available and where a condensate pump would add additional cost for no appreciable benefit.
  • Hi E Dry Vehere





  • The Vehere benefits from a corrosion resistant stainless steel cabinet which improves its appearance for use within the pool enclosure and protects it against the high humidity found in this application.
  • While ideal for swimming pools and other high humidity applications the Vehere is more expensive than the basically similar HI-E Dry 195 and the cheaper model will probably be preferred for other applications in drier conditions or where a ducted installation is possible.
