High energy consumption of the two manufacturing companies
Three Volter 40 CHPs
Covering own energy needs and getting income by selling excess to the grid
Profitable manufacturing without compromising the environment
John Ruck Construction design, fabricate and erect structural steelwork and clad steel framed buildings. Their service includes the whole process for structural steelwork projects, all the way from the beginning to paint. The company was established in 1976, and since then they have worked with industrial, commercial, agricultural and prestige projects. John Ruck Construction is committed to health and safety, quality and equality in their work, but also to the environment; they are working for a sustainable future and always look for ways to minimise harmful effects on the environment.
Side by side in the custom build factory operates a woodchip production business, Elms Green Woodchip. The company provides locally sourced, dried, stored and delivered woodchip throughout Shropshire, Hereford, the Midlands, Gloucester and Mid Wales. The trees that are sourced for woodchip are used in their natural state to ensure there is no contaminant. With that, and by allowing the wood season and by mechanically reducing the moisture level of their woodchip, the company can guarantee the high quality of their product. Trees harvested for woodchip are replaced to ensure the renewable aspect of their business.
"The ArborElectroGen45 [Volter 40 CHP] units are a great design because they are compact and slick, so they can easily fit into a building. I would definitely recommend them to anyone considering biogas CHP systems."

Reducing energy costs with sustainable on-site energy production
Since the two companies are operating at the same premises, the energy demand of the site is high. The owner John Ruck started to search for a way to reduce energy costs. Having the interest in renewables, he started to consider CHP systems. Volter 40 Combined Heat and Power plant was selected because it provided the perfect solution for both their electricity and heat demands.
Power of three Volter 40 CHPs providing enough electricity to sell the excess
Three Volter 40 CHPs were installed to cover most of the site’s electricity need. These independent CHPs are also feeding heat to different buildings within the manufacturing plant, for example, to dry the steelwork painting. In addition, the heat from the CHPs is used for drying woodchip, which has added the drying capacity. Outside working hours, the electricity is exported back to the grid, making the site itself a net exporter of electricity.

This installation was done by Volter’s distributor in the UK, Arbor Heat and Power.
Solution: Volter 40 Indoor
Fuel: Woodchip Electric power: 40 kW Heating power: 100 + 20 kW
One Volter 40 Indoor produces enough electricity and heat for the annual needs of a farm, an entire small housing estate or small business. Our plants can be scaled up to multi-unit installations in order to meet the needs of growing energy demand across diverse applications. Electricity is produced by gasifying wood chips. Waste heat from the process can be used in hydronic underfloor heating, preheating of air-conditioning or domestic water, to name a few.More about Volter 40 Indoor
