We are a Process Bath Heater Manufacturer
A process bath heater is a unique solution to specific requirements in industrial heating. The heater is designed to indirectly heat process liquids or gaseous mixtures by submerging a process coil in a heated bath solution. This type of industrial heater is simple, effective, and reliable.
Sigma Thermal designs and manufactures 3 types of process bath heaters:
- Weir Process Bath Heaters
- Water Bath Heaters
- Salt Bath Heaters
The Water Process Bath Heater
A water-glycol mixture is the most common solution for this type of heater that can be operated safely at lower temperatures. It can normally be heated up to around 250F. It works by submerging a fire tube style burner into the bottom of the process heater vessel.
The Salt Process Bath Heater
These can be operated safely for extended periods at much higher temperatures than the water bath type process heaters. But the physical operation is exactly like the water bath process heater.
Weir Process Bath Heater
The Weir process bath heater is a slight variation of the water bath heater. The main difference is that a Weir process bath heater doesn’t utilize a coil. The bath vessel contains a fire-tube and a weir at the end of the fire-tube. The process fluid comes in direct contact with the fire-tube as it is heated. The fluid then falls over the weir where the return line sends it back to the process user.
Sigma Thermal’s designs can be optimized for indoor, outdoor or hazardous work areas. Our process bath heater design is extremely compact, reliable, and simple to operate and maintain.
