MM hot air generators are indirect heating type equipment (hot air does not mix with the flue gases) and they work totally autonomously.

They do not need additional heat dissipation elements, reducing the costs of acquisition, installation and maintenance.

Its operation is based on heating a certain air flow, through the combustion of diesel, natural gas or propane gas. This flow is sucked in and driven by the fans that the equipment incorporates and comply with the ERP 2020 regulations.

The main advantages over other heating systems are:

  • Reduction of acquisition and installation costs
  • Very fast heating system
  • Air diffusion can be direct or a duct network can be applied
  • 90% combustion efficiency
