PRODUCTS
With over 40 years of expertise in energy recovery, Helical is committed to reducing dependence on fossil fuels through a diverse range of carbon-negative and carbon-neutral solutions, addressing climate change from multiple perspectives.
​Our Core Products
COTSG (Circular Once Through Steam Generator)
Our COTSG technology is the most advanced method of generating high quality steam from waste heat sources such as gas turbine and recip engine exhausts. Our technology uses helically coiler finned tube heat exchangers which are typically 10% more efficient than traditional rectangular heat exchangers due to the Dean Effect. Our technology can be used to generate steam up to 900C with additional firing and can also include hydrocarbon gas such as methane blended into the steam to produce a highly reactive reformer gas containing hydrogen and carbon dioxide. Our technology supports highly efficient gasification processes with carbon capture.
CWHRU Compact Waste Heat Recovery Unit)
Our CWHRU technology based on similar principles to the COTSG is the best solution for heating fluids with exhaust heat from gas turbines and recip engines such as thermal oil, water, glycol etc. The highly efficient circular design has a much smaller footprint, lower weight, comes fully assembled and tested and is much better value than traditional rectangular designs. It is ideal both offshore and onshore.
CALCINER
Our calciners are used for calcium looping to separate carbon dioxide stored in calcium carbonate sorbents. Our circular designs are based on helical coils which benefit from the increased efficiency of the 'Dean Effect'.
​​
WHRUs
Helical’s WHRUs are designed to capture and reuse waste heat from industrial processes, converting it into valuable energy. These units help facilities optimise energy usage, reduce costs, and shrink their carbon footprint, making them indispensable for sustainable industrial operations.
​​
​WHBs
Our waste heat boilers capture and repurpose waste heat from high-temperature industrial exhaust gases, transforming waste into an energy resource. These systems lower fuel costs and COâ‚‚ emissions, aligning with global sustainability goals.
​​
RECUPERATORS
Helical’s recuperators recycle heat within various industrial systems. By preheating combustion air or other process streams, these systems dramatically reduce energy consumption and fuel requirements, enhancing both economic and environmental efficiency.
​​
GAS COOLERS
Our gas coolers ensure optimal gas temperatures for safe and efficient industrial processes. Designed to handle extreme temperatures, Helical’s gas coolers not only boost process efficiency but also enable safe management of waste gases in various sectors.
​Why Choose Helical?
With a focus on carbon-negative and carbon-neutral solutions, Helical addresses climate change from multiple angles, enabling industries to adopt cleaner, more sustainable practices. Our technologies enable substantial reductions in greenhouse gases, creating lasting positive impacts.
