Context

The Long Rock rail maintenance depot in Penzance underwent a £20m redevelopment which included the construction of a new depot and a complete refurbishment of the existing shed.

Work undertaken

The heating solution for the new facility was provided by Reznor, part of Nortek Global HVAC (UK) Ltd. A total of 34 Nor-Ray-Vac burners each supplied with ducted fresh air comprising 24 x 38kW, 8 x 24kW and 2 x 18kW NRV burners arranged in six temperature zones controlled by SmartCom controllers. Each radiant system has a dedicated flue charge to atmosphere. Suspended at 11m, arranged in two temperature controlled zones each with a discharge to atmosphere.

Suspended from the roof, the heaters emit infra-red rays that warm only objects and people in its path. They do not waste fuel heating the volume of air in the building. This will ensure that heating costs are kept to a minimum.

Challenges

The depot had to remain fully operational 24 hours a day throughout the installation. Other challenges included the removal of asbestos, constructing around and over a live sub-station, building a cantilevered roof over the old shed and removing steelwork from the inside. The project also needed to be completed within the 18 months of contract award to allow the HS2 project to close part of Old Oak Common depot by Christmas Eve 2017 and transfer the sleeper heavy maintenance to Penzance.

Key benefits

  • Even heat coverage throughout the building
  • Rapid warm-up time and low noise operation
  • Great occupancy comfort and lower operating costs

Installation summary

  • Reznor installed a Nor-Ray-Vac continuous radiant tube heating system.
  • Suspended from the roof, the heaters emit infra-red ray that warm only objects and people in its path.
  • Low operating costs are achieved by concentrating the heat at low level.

Technical summary

  • Area: 4486m2
  • Height: 8m and 10m
  • Volume: 40,675m3
  • Heaters: 34 NRV LR ducted air burners
