Derby Etches Park Refurbishment
In 2013, Brakel Airvent installed 33 replacement fans at the Etches Park railway maintenance depot in Derby, designed to regulate the build-up of potentially hazardous fumes (CO, NO2 and CO2) from the rolling stock and ancillary equipment in the workshop areas. Subsequently it became apparent that the building’s layout did not allow for suitable inlet of fresh air, causing the fan arrangement to run more often than needed due to increased concentrations of fumes and further CO2 build-up from gas-fired radiant heaters running at suboptimal efficiency.
The client, Sisk Rail, decided that a refurbishment of the site’s ventilation system was required to improve airflow and energy efficiency, with Brakel Airvent being appointed on account of its expertise in the rail sector and familiarity with the customer and location.
Brakel Airvent’s solution consisted of two core avenues: to directly upgrade the efficiency of the fan arrangement and to improve the airflow in the building.
The fan upgrade involved the replacement of an existing 20+ year old control panel and the addition of inverters, allowing for variable fan speeds and therefore greater energy efficiency.
The airflow issue was addressed with the removal of existing Georgian wire-glazed windows, to be replaced with 13x Brakel Eura louvered ventilator windows. Installation was undertaken by Brakel Airvent specialist engineers harnessed to roof anchors for safe working at height. The Eura can allow efficient passage of large volumes of air, with sensors across the building’s three zones determining the required inlet air and fan speed.
The system arrangement is in accordance with Approved Document F covering the build-up of hazardous gases in service areas.
