Engineering Rigour
From Peterborough to process plants worldwide — our journey.
EnerTherm Engineering was founded in Peterborough, United Kingdom with a clear mission: to help process industries reduce energy consumption, cut emissions, and improve operational efficiency through better thermal engineering.
What began as a specialist consultancy in thermal design and energy auditing has grown into a comprehensive engineering partner — designing and manufacturing industrial thermal equipment alongside delivering advanced process engineering services across 14 disciplines.
Today, we serve industries ranging from chemical manufacturing and pharmaceuticals to food processing, agriculture, defence, and waste management. Our approach combines deep thermodynamic expertise with modern simulation tools, data-driven analysis, and a relentless focus on practical, implementable solutions.
Products
7 product lines including incinerators, heat exchangers, process heaters, thermal oxidisers, condensers, dehydrators, and the EcoLog data logger.
Services
14 engineering disciplines from energy auditing and pinch analysis to CFD simulation, process modelling, and bespoke software development.
Industries
50+ industry sectors served worldwide — from petrochemical plants and pharmaceutical facilities to agricultural operations and military installations.

Our
Journey
From a specialist consultancy to a comprehensive thermal engineering partner.
EnerTherm Ltd Founded
Established by Dr. Francois Pierrel with a primary focus on developing Thermal Insulation Coating. Over 1,000 formulations were developed to produce sprayable water-based thermal coatings, with 50+ live trials conducted for clients such as Chevron Oil. The intellectual property for this low-temperature (170ºC) technology was later sold to Hempel in 2021, resulting in Hempatherm IC 175 and Hempatherm IC 170.

Team Expansion & Key Projects
New employees joined to manage daily operations and address increasing demand for engineering design. Key projects included solid waste incinerators for multiple UK customers, a dehydrator for the food industry, a large rotary dryer and cooler for aluminium recycling, and an incinerator and heat recovery system for Rolex for waste treatment. In 2018, developed and released EcoLog V1.0 — a proprietary PLC-based data logging system capable of monitoring any tags directly from a PLC.

What Drives
Our Work
Six principles that guide every project, every recommendation, every design.
Innovation
Pushing the boundaries of thermal engineering through advanced simulation, data-driven design, and emerging technologies like hydrogen-ready systems.
Sustainability
Every solution we engineer is measured against its environmental impact — minimising emissions, maximising energy recovery, and supporting net-zero pathways.
Integrity
Transparent pricing, honest assessments, and engineering recommendations driven by what is right for your process — not what is easiest to sell.
Precision
From CFD simulation to on-site commissioning, we apply rigorous methodology at every stage to deliver measurable, repeatable results.
Partnership
We embed ourselves in your operations, working as an extension of your engineering team rather than an external contractor.
Knowledge Transfer
We train your operators, document our methodology, and ensure your team can maintain and optimise solutions long after project completion.
What We
Deliver
Products, services, and expertise that span the full thermal engineering lifecycle.
Thermal Equipment Design
Incinerators, heat exchangers, process heaters, thermal oxidisers, condensers, and dehydrators — designed and built in Britain.
Process Engineering Services
Energy audits, pinch analysis, heat & mass balance, process modelling, simulation, and optimisation across all process industries.
Data-Driven Analysis
CFD, FEA, Design of Experiments, and advanced thermal simulation to validate designs before fabrication begins.
Bespoke Manufacturing
