Process Heating Systems and Solutions for a Variety of Industrial Applications

Amine & Glycol Reboilers

are used to strip the acid gas or water from amine or natural gas streams without causing degradation to their respective fuels.

Ammonia Heating

is a carefully gauged process leveraged in properly heating NH3 which is delivered by way of distribution tankers to agricultural crops during planting season.

Calendar Rolls

are utilized in manufacturing textiles, paper and plastic sheeting ensuring a smooth, uniform and high quality finish by way of passing items through heated rolls.

Condensate Stabilizers

are often applied at natural gas well sites to help flash off and separate lighter gases from the stream by regulating the temperature and pressure.

Dew Point Heating (Joule-Thomson)

is a crucial component of the fuel gas heating process for gas turbines and power generation. Dew point heating ensures that water or fuel gas condensates do not enter the turbine, which can cause damage to equipment through the creation of extra exhaust during combustion.

Dryers & Kilns

are complex systems used in the preparation of lumber and engineered wood production. Available in numerous configurations, they can use a variety of energy sources.

Edible Oil Deodorizers

are created by way of steam distilling crude edible oil forms which will evaporate all odorous elements resulting in refined oil with a specific taste profile.

Freeze Protection

solutions are engineered to aid in a variety of industrial processes that can help ensure the operation or safeguarding of equipment during inclement weather.

Fuel Gas Conditioning

is a process which not only helps remove contaminants from gas streams, but optimizes efficiency and helps keep systems in compliance with regulations.

Indirect Steam Generators

are used for heating in industrial applications as well as a means to create driving force in turbines and motive force in liquid streams.

Jacketed Reactor Heating & Cooling

solutions consisting of thermal oil or water/ glycol mixtures help to safely remove excess heat or provide additional heat to desired reactions.

Jacketed Vessels

introduces a secondary enclosure over a structural shell. The jacket creates a cavity to be utilized for heating and cooling management, usually by filling the space with a circulating fluid.

Liquid-Gas Vaporization

solutions utilizing high pressure and a series of heat exchangers help to change liquefied products back to their gaseous state for feeding into grids.

Molding & Extrusion

solutions that meet very specific temperature tolerances are available to ensure the highest quality in molded or extruded components.

Molten Salts

sometimes referred to as salt melts, are a family of products used for a wide range of applications like high temperature process heating, heat treating and annealing of steel, and thermal storage in solar thermal power plants. These salts are composed of fluoride, chloride, and nitrate salts.

Ovens & Fryers

solutions in the industrial food industry seek to provide uniform, efficient thermal energy while maximizing the quality, appearance and yield of goods.

Plant Utility Heating

solutions often consist of direct and non direct heating systems to help create an ideal application that addresses the heating needs of all locations.


are often utilized in many manufacturing processes, whereby pressure and heat are combined to assist in molding, bonding and lamination as well as composite molding.

Process Air Heating

is essential in processing facilities where the distribution of air at controlled temperature to multiple processing streams is a key factor in efficiency.

Regeneration Gas Heating

technology can be used to help mitigate the risk present in the use of regeneration heaters in the presence of highly combustible oil and gas products.

Steam Superheating

solutions can be devised for propulsion and drive applications while ensuring that the steam flow remains a gas that will not condense into a vapor.

Seal Gas Heating

solutions typically utilize high pressure combined with a high purity seal gas to ensure that no leakage takes place in centrifugal compressors.

Tank & Suction Heating

solutions are essential in helping to protect storage tanks and process vessels against freezing temperatures and maintain fluid temperatures.

Viscosity Reduction

solutions help to increase the mobility of crude oil and crude oil derivatives by way of indirect heating minimizing degradation of the product.

Waste to Power

To convert waste heat energy into usable electricity, Sigma Thermal has partnered with ElectraTherm, to offer an integrated package containing an Organic Rankine Cycle (ORC) generator, helical coil heater, condenser, and evaporator.
