Industrial Heat Recovery Units

Updated: June 27, 2022

When your work releases fumes into the air, having a quality air controlling system is necessary for comfort and safety. Industrial heat recovery units are just as important to your business as an air makeup unit. Together, heat and air control can help you reduce waste, lower costs and improve energy consumption. 

What Are Industrial Heat Recovery Units? 

Industrial heat recovery units store the warm air released from areas such as blast or spray booths and use it to heat the incoming fresh air. While you remove the dust and debris to create better air quality, heat recovery units capture the escaped heat and repurpose it. 

There are a few advantages to installing waste heat recovery technology, including: 

  • Stable temperature: You can monitor the temperature and keep an ideal climate for workers and materials.
  • Lower energy values: Reusing energy will prevent you from using excess power to heat the area. 
  • Improved costs: As your energy levels decrease, so do your operation’s costs. You can save money on heating and power overall. 

This technology can also involve cooling coils that help reduce energy in the warmer months while keeping the internal temperature comfortable. 

What Do Heat Recovery Units Do?  

Industrial heat recovery units capture waste that would normally be emitted into the surrounding atmosphere and store it so you can use it for other purposes. Some examples of heat waste include hot exhausts and gases. There are varying technologies that apply to each system, but the main components include:

  1. An entry point for the escaped exhaust and one for the incoming air.
  2. The heat recovery unit, which absorbs the heat through different methods. 
  3. An exit point for each entrance that pumps out cooled air to the outside and heated air inside. 

There are a few different ways to transfer the heat from the exhaust to the fresh air. 

Thermal Wheels

Thermal wheels are the most efficient units. They consist of two large wheels that turn in opposite directions — one draws in the exhaust and the other churns out the clean, heated air. The energy from the exhaust air transfers to the clean air, which heats it.

Heat Pipes

Heat pipes operate with a tube system and refrigerant to convert waste air to clean, warm air. The refrigerant captures the heat from the exhaust air and transfers it to the incoming or reserved fresh air. These pipes can be either horizontal or vertical. Vertical lines rely on evaporation, whereas horizontal pipes employ wicks to capture heat. 

These two mechanisms — thermal wheels and heat pipes — accomplish the same goal of trapping heat and creating warm, clean air. No matter the internal process, the heat recovery unit’s purpose and main components are the same.
