A radiant–convective style heater is the most well-known and commonly used style of direct-fired heater. These heaters utilize a bare tube radiant zone in combination with a bare / finned convection section. Vertical cylindrical, A-frame, and cabin style are the most common configurations. Sigma Thermal offers all types of radiant–convective heater designs including API 560 ...

Used largely in the wood products industry, where higher moisture content fuels such as hogged bark and green wood chips are available. The reciprocating grate achieves gasification through the staged combustion of wet fuel. Our grate is divided into multiple sections, allowing for varying speeds and controlled underfire air zones, resulting in the combustion of your fuel in a manner that is ...

The pre-engineered HC2 thermal fluid heater is available in standard sizes from 500,000 to 100 MM BTU/hr. Configuration options include vertical up-fired, vertical down-fired, and horizontal. This system is skid mounted with a burner and integrated control panels. Sigma Thermal also offers custom thermal fluid heater designs for a wide variety of project-specific design challenges. ...

Sigma Hot Oil Transfer System (SHOTS) are electrically powered thermal fluid heating systems. SHOTS incorporate an electric circulation heater with a low watt density immersion bundle and fluid circulation pump to create a simple, robust, and reliable system. This system uses electricity to heat your thermal fluid instead of natural gas, fuel oil, or biomass fuel sources. We also offer custom ...

The bath solution is heated by a fire tube style burner submerged at the bottom of the heater vessel. Water-glycol mixtures are very common solutions for most low-temperature heating applications, and can typically be used up to 250F. ...

Electric immersion heaters are typically inserted directly into a pipe, tank, or vessel to heat process gases or liquids. Since the heat is generated by electricity, virtually all of the energy is consumed by the product being heated. As a result, the liquid is heated near 100% efficiency. With standard elements constructed of Alloy 800, these heaters are designed to heat a variety of fluids and ...

The high-pressure steam generator produces non-toxic process heat. NUK® High-Pressure Steam Generator: The NUK® High-Pressure Steam Generator is a closed-looped (hermetically sealed) system that produces steam for high-temperature applications. Therefore, this steam generator is able to produce non-toxic process heat while offering the same advantages of a conventional hot oil ...

An electric process circulation heater is used as a conduit to facilitate the flow of process fluid directly over heating elements. Circulation heaters heat a variety of fluids from high-temperature gas to hard to heat liquids. The heating elements, vessel, terminal connections, and mounting structures are packaged for quick installation. Heaters may be installed horizontal, vertical or even ...
