Why buy from Addfield?
Our greatest assets are the people we employ. As our machines are individually handcrafted, we use over twice the number of labour hours to create our machines than our competitors.
Being the UK’s leading manufacturer of quality equipment for over 30 years proves that the Addfield range of machines are reliable and have the durability to stand the test of time.
Our equipment has become the leading equipment to solve all waste solutions. Where most of our competitors machines last 2-5 years, the very first Addfield machine was built over 30 years ago and is still in operation.
Cutting edge design
Unlike its competitors, Addfield insist on specific machines for specific applications, we do not believe one machine fits all applications. You will note from our range that we have different designs for different industries.
The Addfield machines are unique in their own right as we utilise Computational Fluid Dynamics software to design our incinerators, this software helps us predict gas flows, cold spots, burn rates and ensures fuel efficient solutions. It is the same software used to design Formula 1 cars, Petrochemical Refineries and many more high tech industries.
Craftsmanship at work
Our unique designs are handcrafted by our highly skilled workforce. Traditional methods of construction are used by time served masons to create our robustly built and thermally efficient machines. Utilising these traditional methods and skills ensures the buyer a realistic return on their investment. But don’t just take our word for it! Come and visit us to see our craftsmen at work.
Maximum energy efficiency
When compared to other designs, the Addfield machines ARE not only the most robust but also the most thermally efficient on the market, ensuring maximum energy efficiency throughout the burn process.
Our multi-layered refractory lining systems have been specifically developed to not only ensure the maximum and efficient use of fuel during the burn process, but also for the longevity of the lining systems and ongoing ease of maintenance.
Clean burning for reduced emissions
Unlike some of our competitors ALL of machines have secondary combustion chambers that comply with EU legislation for achieving either 850c with a residence time of two seconds or alternatively 1100c with a residence time of 0.5 seconds. Working to European standards reduces emissions and ensures a complete clean burn every time. All of the Addfield range of machines DEFRA/ Environment Agency approval and comply with the EU Animal By-Products Regulation (EC) No 1069/2009.
The Addfield EcoCycle™ trademark is an accumulation of energy efficient technologies developed by Addfield. This knowledge allows us to create some of the most fuel efficient, and eco-friendly machines on the market today, what’s included in the EcoCycle technology.

Making the heat work for you
Making the heat work for you – Our 200mm of multi-layered refractory lining is designed specifically to retain the energy created during the heating process and restrict the amount energy lost through the walls. Using the most up to date refractories and undertaking in-depth thermal calculations ensures the lining systems we install are completely thermally efficient.
Why do we use Bricks instead of Concrete?
This is a question that we are asked continuously, there are many reasons for this. We do use castables in some of our more geometrically intricate designs; however, our focus is to utilize bricks over castables at every opportunity.
One of the main things to remember is that there are many potential problems with cast linings as they are mainly mixed and installed in situ. All of the following items or even just one can result in catastrophic failure of the cast lining system. Anchorage, too much water during mixing, over vibration, no vibration, over mixing, poor formwork leading to water loss. Whereas refractory bricks are hydraulically pressed together in a 30,000MT press and fired to 1600c making them a true ceramic which needs no further dry out or thermal treatment as they are good to use immediately. With cast linings, labour is generally inexperienced whereas in brick linings time served refractory masons are used for the installation.
Key things to look for in a refractory lining are as follows: porosity (the lower the better) brick have a porosity of 14% cast refractory can be over 26%, thermal shock resistance, stability under temperature load, ease of maintenance. We are the only UK manufacturer that use brick for most of their lining systems and have done so for over 30 years, our lining systems have stood the test of time.
Bricks vs Concrete
|Qualities||Cast Refractory||Brick Lined|
|Pre-Fired||No||X||Yes to 1600c|
|Installation Labour||None or semi-skilled||X||Time Served Masons|
|Anchorage||Stainless (burns out)||X||Bonded interlocked|
|Joints||None. Prone to crack||X||Yes|
|Manufactored||On site by hand||X||30,000MT Hydraulic Press|
|High Temperature Resistance||Not very as anchors fail||X||Very stable under hot conditions|
|Ease of Maintenace||Very Poor||Very Easy|
Pulse firing burners
Aid a clean burn process. Our burners turn off once the machine is up to temperature saving fuel and giving a cleaner burn process. The burners continuously inject secondary combustion air into the chambers to utilize the calorific value of the load. With our lining systems being so thermally efficient means that the burners are not needed to continuously inject fuel into the machine thus reducing fuel costs.
