Case Studies Watkins Hire 500kw Warm Air-Handling Unit Industrial Commercial Heating

When First Great Western wanted help to replace a competitors torpedo portable heaters, They contacted Watkins Hire for a hire solution that provided them with equipment that had no direct fired naked flame but can still provide large volumes of safe, dry, fume-free heat air to heat the train maintenance shed at Plymouth. The building was 150m long by 50m wide and 20m high.

First Great Western is part of FirstGroup plc, a UK-based leading international passenger transport group with an annual turnover of £2 billion and 50,000 employees across the UK and USA. First is the UK's largest bus operator, a major force in railways running one fifth of Britain's passenger rail network, and London's only tram operator.

The client explained to Watkins Hire that the building had 28 portable heaters from a rival company, which were not efficient at heating such a large space, the client also had many issues with the LPG and oil fired heaters:-

  • Overall cost against the heat benefits
  • Inefficient localized heating
  • Too many units scattered throughout the building
  • Labour intensive changing over LPG storage bottles.
  • Risk of fuel spillages, in refilling oil fired heaters.

Watkins Hire interpreted the site requirements, equipment required for the project included a 582kW HeatGEN mobile packaged boiler plant fuelled by 35 sec fuel oil, 500kw Warm Air Handling Unit, 300 meters of 20 inch flexible ductwork, a 3000 litre bunded fuel tank, Fuel supply and fuel management, 50 meters of flow and return pipework, system pumps to match the flow, volume and resistance of the pipe distribution network and AHU. The HeatGEN was selected from one of Watkins Hire extensive fleet of 350 mobile boiler plants.

The HeatGEN and associated plant was delivered the day after of the initial call, with Watkins Hire own transport and lifted onto site with Watkins Hire 12 tonne HIAB crane. With the 582kW HeatGEN mobile packaged boiler plant in place the next phase of the project to install. The installation proceeded well with Watkins Hire engineers on site as the boiler arrived; they installed all the pipework for the flow and return lines to the internal air handling units, with Watkins approved subcontractor installing the flexible 20 inch ductwork, with no disruption to the day to day running of the train maintenance.

From the time of delivery to site and Watkins Hire Engineers commissioning and handing over the plant to the client was completed within 2 days.

A spokesperson for the First Great Western said "We are extremely pleased with Watkins Hire and their professional approach to our space heating project, and the efficiency in the way the whole contract was handled, without hesitation we will be contacting Watkins Hire again. The standard of equipment and service was second to none, we now know what they can deliver"
