New Boilers
for purchase
Incredibly dependable and energy-efficient
For all your pressure steam needs
Our ‘new design’ Kelford Electric Steam Boilers are self-contained with integrated feed-water and blow-down tanks. They don’t generally require any additional ancillary equipment as with other electric steam boilers.
Kelford Electric Steam Boilers are very efficient. They are compact and require no venting. Steam is discharged directly from the electric boiler for a quick, efficient operation. Either model can be modified to fit with purpose when necessary and yet either model will fit with most requirements.
We are able to design and build to specific project requirements.
Our boilers are reknowned for convenient use, simple operation, economical and support a wide variety of applications.
