Enterprise Natural Gas Burners 20kW-8,000kW
The Enterprise natural gas burners cover a firing range from 35kW to 8,000kW and are suitable for small, medium and large applications.
The Enterprise burners are designed to be aesthetic and functional but at the same time gives prominence to innovative technologies; in fact all components can be fitted onto a backing plate which can be moved and attached to special fixings within the burner to make maintenance easier.
The models can be supplied for operations as follows:
- TN: On / Off
- AB: High / Low
- PR: Progressive
- MD: Modulating
Enterprise burners feature a high performance combustion head which ensures safety and increased efficiency. These units also feature simplified maintenance through convenient access to essential areas. A cam driven by the modulating motor ensures a smooth transition from low to high fire.
