Computational Fluid Dynamics

+ Details

CFD uses numerical analysis and algorithms to solve and analyse problems that are involved fluid and gas flows.

Our Engineers design, model and perform the calculations required to simulate the interaction between solids, liquids and gases with surfaces and paths defined by boundary conditions.

Complex simulation scenarios such as turbulent flows can be achieved through to the final validation and full-scale testing.



Finite Element Analysis

+ Details

Is a computerised method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow, and other physical effects. Finite Element Analysis shows whether a product will break, wear out, or work in the way it was designed to be.



Mechanical Engineering

+ Details

Is the discipline that applies the principles of engineering, physics, and material science to the design, analysis, & manufacture of a product.



Electronic Engineering

+ Details

Is an engineering discipline which utilises active electrical components and devices, diodes and integrated tracks to design electronic circuits, devices and systems.

EXPEL will not only drastically reduce the running and maintenance costs of your compressed air lines, but it will increase energy efficiency and reduce your environmental impact!

Expel is the world’s first cleanable and reusable compressed air filter. A remarkable product which unlike a traditional compressed air filter, never needs internal elements replacing. Therefore, its performance and efficiency does not reduce over time. This is reinforced by the 10 year guarantee we offer on every Expel unit. Furthermore, no unnecessary costs or wastage are generated by replacement filter elements.

The Expel filter has been designed so it optimises energy efficiency as much as possible. Its patent protected design does not retain the compressed air contaminates it has been designed to remove. Instead, it quite literally ‘expels’ them from the unit. This means that no extra energy is needed to pass through the unit.

"The moment I saw EXPEL I fell in love with it... I thought, this is what the industry needs."

Bruce Somerville, UK Sales Manager, Rema Tip-Top

"EXPEL has had a big impact on our business. It's greatly reduced the water and it's greatly reduced the maintenance costs of the fitting machines."

Trevor Standeven, General Manager of Lodge Tyres

"Extremely satisfied... extremely. This little, tiny filter that does the job of thousands of dollars worth of equipment is incredible. I'm really astonished by it."

Matt Monte, Econotyres (owner) Miami USA

“We install Expel before every valve and solenoid, in the past we put them just after the compressor but now we know where to put them and how to get the best efficiency out of them. We didn’t know anything about Expel and usually we don’t buy new products to try, but we decided to trial Expel because you gave us one and knew if it wasn’t effective, we could just send it back… But Expel has made our system a damn lot better.”

Stephen Jones - Workshop Manager of North East Breedon sites

“Expels were put into protect a bitumen selector valve and air controlled dust valve that suffered from water damage. We now have no issues and are extremely happy with Expel.”

Jason Fairbrother – Asphalt Plant manager – Tarmac – Mountsorrel Asphalt Plant

“We had problems with dampness getting into the solenoids, so it was causing them to stick which causes problems with bin doors opening so it would cause loss of production. We looked at a dryer but the Expel was much more competitive and you didn’t have the running costs of electricity and servicing costs, so it was much more efficient. We found expel very efficient, we are very pleased with it we would recommend it”

Stephen Harrison – Production Manager – Breedon – Crime Rigg Concrete Plant

“I am very happy with Expel, I would highly recommend Expel and I have been recommending it to other sites too”.

Steve Pointon, Operations Manager
