The Client 

PQ Corporation is a global chemical manufacturing company with a large-scale facility based in Warrington, UK. The site’s size and operational complexity posed significant challenges when it came to upgrading legacy network infrastructure. 

The Background 

Faced with ageing network equipment distributed across a vast and operationally sensitive site, PQ Corp needed a reliable partner to manage the end-to-end replacement of 55 network switches. Minimising disruption was critical, as any downtime could impact essential business operations. The project required both technical expertise and the ability to work flexibly across the site. 

The Solution 

MLR Networks delivered a comprehensive service—from planning and pre-configuration to on-site switch replacements. Their meticulous documentation and clear communication enabled PQ Corp to understand the scope of work and effectively coordinate network outage windows. 

To further reduce operational impact, MLR scheduled high-impact swap-outs outside of normal working hours. This proactive and collaborative approach ensured a smooth deployment across all 55 switches. 

“MLR helped us tremendously with the replacement of these devices, taking away the intensive tasks of configuration and swapping out the devices at an agreed date and time.”

The Results 

The project was completed without major disruption, and PQ Corp now benefits from an up-to-date network infrastructure supported by comprehensive documentation and accurate site drawings—something the site had never had before. 

“This is the first time we actually have an up-to-date package with network drawings and documentation for this site.” 

MLR’s customer service was also praised for its clarity and responsiveness. 

“We’ve had very direct contact, including one-to-one conversations and Teams chats. MLR communicated with the on-site staff and handled all questions that arose.” 

As a result of this successful collaboration, MLR Networks is now viewed as a trusted partner for PQ Corp’s ongoing and future networking needs. 

“We will definitely be utilising MLR more for network tasks that require on-site staff to be present.”

PQ Corp enthusiastically recommends MLR Networks to other businesses requiring network infrastructure services.
