What do we provide?
J Wren Electrical Ltd provides specialist electrical and control system design, installation, and long‑term support for powered mobile racking systems within large industrial and commercial warehouse environments. With over 25 years’ experience, we support high‑density and semi‑automated storage systems used in cold storage, vertical farming, logistics, and large commercial warehouse facilities across the UK, Europe, and the USA.
Our expertise covers complete safety and control integration, including safety monitoring relays, variable speed drives (VFDs/VSDs), and system diagnostics. Whether delivering a turnkey solution or acting as a specialist partner, we focus on reliable and efficient mobile racking operations across the lifetime of the system.
Whole Life
We offer whole‑life support for powered mobile racking systems, with preventative maintenance and around responsive support positioned as a core service, with our engineers available both remotely and onsite.
Service
Our service packages include consulting and system design, maintenance and servicing, refurbishment and repairs, parts supply, inspection, and compliance. A key part of our offering is preventative maintenance inspections, helping to reduce downtime, extend equipment life, and ensure continued safe operation.
Emergency Support
We offer remote engineer support, assisting customers’ own engineers during faults, troubleshooting, or breakdowns. We also provide in-person emergency call‑out support with one of our trusted engineers. This ensures expert assistance is available when and where it matters most, minimising disruption to warehouse operations.
