How we save energy

With Air-to-air Exchangers

Heat Wheels are the most energy efficient and the most popular technology used at Annexair. From 2,000 CFM to 80,000 CFM capacities, Enthalpy wheel units are available with a wide sequence of cooling and heating options based on your requirements.


Fixed Plates are our second most popular technology we use. From 2,000 CFM to 80,000 CFM capacities, Fixed Plate units are also available with a wide sequence of cooling and heating options based on your requirements.


Dual Wheels are our third most popular design we offer. From 4,000 CFM to 40,000 CFM capacities, Dual Wheel units include an Enthalpy and Sensible wheel combination for dehumidification purposes, with either DX or CW cooling and different post-heating options based on your requirements.


Another popular design for dehumidification purposes is a combination of an Enthalpy Wheel and Fixed Plate. From 4,000 CFM to 40,000 CFM capacities, these units are also available with either DX or CW cooling and different post-heating options based on your requirements.


When return air is not available and you require make-up air, adding a Fixed Plate reduce cooling capacity requirements of up to 20%, and supply air at a lower dew point temperature. These units are available with either DX or CW cooling and different post-heating options based on your requirements. Sizes are available between 2,000 CFM to 10,000 CFM.


Required for special applications, Heat Pipes can save energy when carry-over rate is critical. From 2,000 CFM to 10,000 CFM capacities, these units are also available with either DX or CW cooling and different post-heating options based on your requirements.


A Wrap-Around Heat Pipe is another technology that can be incorporated alone in any air handling equipment, such as a make-up air’s, or combined in an Enthalpy wheel unit. Sizes are available between 2,000 CFM to 25,000 CFM, and are available with either DX or CW cooling and different post-heating options based on your requirements.
