AhD Series - High Capacity Dehumidifier
AhD products provide room dehumidification for industrial or commercial applications.
Excess humidity levels generated by some industrial processes or exposed water surfaces can cause damage to building structures and equipment, and may even create health concerns. Other industrial applications require controlled humidity levels to optimize their processes.
E-Tech AhD dehumidifiers can solve most humidity problems by efficiently cooling the air below the dew-point temperature and then reheating the air back to the desired space dry bulb temperature. This greatly reduces the moisture content and relative humidity of the air without overcooling the space.
Specific applications include:
- Natatoriums
- Fitness centers
- Gymnasiums
- Food storage areas
- Production clean rooms and dry rooms
- Industrial operations requiring a controlled environment
- Any indoor facility having mold or mildew problems due to excess air moisture content.

AhD units can be modified by adding the following available options:
• Economizer Module
The economizer module allows the use of outside air for dehumidification when it is more economical. It is attached to the air inlet of the unit and includes a return air blower and connections to the exhaust and fresh air ducts. Each economizer is provided with three motorized dampers. The use of the Economizer is determined by a dew point controller.
• Remote A/C Ready
This option provides on demand cooling. The unit is provided with refrigerant connections for field piping to an outdoor air cooled condenser. The condenser must be ordered separately, or can be supplied by others.
• Outdoor Air Cooled Condenser
These are the optional outdoor air cooled condenser for use with the Remote A/C ready option to provide on demand cooling. It consists of an air condenser and with an axial fan.

| AhD 30S | RC-30 | 30,000 | 25.5” x 21.75” x 39.5” |
| AhD 50S AhD 60S |
RC-60 | 60,000 | 30.5” x 23.5” x 42” |
| AhD 90S AhD 120S |
RC-130 | 130,000 | 48.5” x 45.125” x 49.5” |
| AhD 150S | RC-150 | 161,500 | 48.5” x 45.125” x 49.5” |
| AhD 180S | RC-180 | 192,000 | 48.5” x 45.125” x 62.5” |
• Built-In Water Cooled Condenser
The AhD can be provided with an integrated water cooled condenser to provide on demand cooling when a cooling water or Geo loop is available for that purpose. Condenser water pumps are not included.
• Custom Air Flow Options
Each AhD can be supplied with customized air flow and can be designed to meet the external static pressure (ESP) required by the application.
• Auxiliary Heating
Each AhD can be provided with an auxiliary heating air coil which to use hot water supplied by another source, or electric heaters can be added to the discharge ductwork of the installation.
