Case Study

Network Rail – Canton Fuelling Depot

UES is proud to maintain a strong relationship with Enerveo, acting as their preferred HVAC contractor in the South West. With vast experience working with industrial clients, SSE have routinely called upon us to confidently carry out works on behalf of them for Network Rail.

A previous job that we have carried out for SSE relied on us responding fast to a critical business emergency callout on a Sunday afternoon in the first weeks of lockdown. The pumps in Canton Fuelling Depot in Cardiff were not pulling enough fuel through to the filling points requiring urgent and immediate action.

As the job was too complex to be carried out there and then, UES managed to successfully install a temporary fuel supply to one of the pumps while we devised a permanent solution. We returned the next day to clean and repair the tubes and valves at the bottom of the commercial tank and helped fix a split in one of the pumps. Thanks to our quick response times, flexibility, and the strength of our team, Network Rail experienced no disruption or loss of business.

We were pleased to be called upon by Enerveo once again in December 2021 to carry out works at the same fuelling depot. Two gas-fired water heaters had fallen beyond economical repair and needed to be decommissioned and removed. The problem Network Rail faced was that these heaters were an essential part of their 24/7 operation, responsible for providing hot water to employee showering facilities and washdown stations for their fleet of trains. Whilst the units were being replaced, the site was staring down the possibility of being without hot water for up to three days.

UES calmly formulated a plan to supply a temporary hot water solution whilst materials were delivered and the new units were installed. A Rinnai external hot water heater was fitted outside of the plant room, the perfect appliance for efficiently drawing hot water directly from the main supply instead of using stored water units. Temporary plastic pipework was put in place as well as installing a temporary cold-water supply from the booster tank to the Rinnai. Following this, a temporary secondary return was installed to the cold-water inlet, and then our electrical team was able to install a temporary power supply to the appliance. Network Rail now had uninterrupted access to hot water whilst we worked on their unit replacements.

Two new condensing Lochinvar units were meanwhile delivered to the site and we set to work fitting them in the space. A new flue system was fixed as well as a new unvented kit to replace the existing one. A condensate waste was installed to terminate to a local drainage system, and the new pipework was insulated in foil-faced lagging. The existing supplies and controls were reworked by our electrical team, and the two units were commissioned and set to work.

To have an arsenal of the newest and most innovative technology on the market from our wide range of trusted suppliers is what keeps UES so consistent and reliable. Once again we were able to deploy quick thinking, logical planning, and quality execution to help our client continue with unobstructed operations. Network Rail didn’t lose any time or business and didn’t face any water issues that could so easily have occurred. Enerveo was once again left content that UES had carried out their work to the highest of standards.
