Part two of this large trace heating project, saw ESH supply, design and install a trace heating system to frost protect the chilled water and basic cold water pipework on top of the office roof. The system was designed to use our type VC constant wattage heating cable, of which, over 600 metres was installed during the first part of the project.
Rackspace is a world leader in cloud computing and hosting and 5 Hyde Park is the home of their UK headquarters.
ESH extended the existing trace heating circuits with the same power rated trace heating cable as already installed. The required application was to temperature maintain the emergency shower pipework at a minimum temperature of +10°C.
Within a Zone I Hazardous Area, ESH designed, supplied and installed a temperature maintenance trace heating system to a section of 1" Ø vessel pipework. The pipework required to be maintained between +90°C and +150°C, this was achieved by straight tracing three runs of type SCBXC12/2 ATEX Approved constant wattage heating cable to the underside of each pipe.
This facility will provide South West Devon with one of the most efficient energy from waste plants in Europe. For this large frost protection application, ESH split the project into two separate systems:
- System one was designed, supplied and installed with type VC constant wattage heating cable onto the range pipework, the manifolds and gel skid pipe, incoming feed, deluge and cannon feed pipes.
- The second system was for the frost protection of 400mm NB steel pipework associated with two hose reels. ESH supplied and installed type ESRS self regulating cable in order to prevent the pipework temperature dropping below +5°C.
ESH supplied and install a trace heating system to temperature maintain a large HCA storage tank at +36°C in a minimum ambient of -20°C. The system, within a Zone II Hazardous Area, required over 150 metres of type SCBX ATEX approved constant wattage heating cable.
ESH were contracted to supply and install constant wattage heating cable to repair a damaged trace heating circuit. The 2" and 3" NB pipework containing PPA needed to be temperature maintained at +100°C.
ESH supplied and installed a trace heating system to provide frost protection to two runs of BCWS pipework. Type VCBOJ constant wattage heating cable was installed onto the external metal pipes and controlled using STCI thermostats.
