Horizontal Industrial Direct Fired Recirculating Heater

(RAM-M)

The Industrial Direct Fired Horizontal Recirculating Heater is designed to deliver make-up air for applications requiring high airflow gas heat requirements within a robust unit casing for variable fresh air to return air volumes. This model offers a factory mounted fresh air and return air damper that varies the amount of air bypassing the burner based on recirculating needs. Units utilize natural or propane gas with a nearly 100% efficient direct fired burner with indoor or outdoor installation options.

  • Air Volume: 7,000 – 70,000 cfm
