Water bath and salt bath heaters utilize a variety of burner, fire-tube, and coil configurations to meet your specific project demands. Forced draft, small-bore fire-tube burners can be utilized for high efficiency and low NOx requirements, and traditional natural draft burners are available for locations with little or no available electricity.

Coil configurations and metallurgy are selected based on each customer's process requirements. Sigma Thermal has extensive experience in process coil design for multi-phase fluids, viscous hydrocarbons, suspended solids, and various gaseous mixtures.
