Through 2007 & 2008 and in addition to those supplied to its UK client base, Therco has supplied 36 x Transformer Oil Coolers to the Castle A&B PowerStation’s in Hong Kong. The ‘like for like’ replacements were manufactured from our Serck serial number and drawing archive dating back to 1983 in this instance. This precise interchangeability enabled the outages at the stations to be kept to an absolute minimum with no pipe work or instrumentation alterations being required. The high integrity internal and external paint systems coupled with copper nickel bundles will ensure the coolers operate fully and well for at least another 20 years (assuming stable operating conditions).

The newly re-commissioned rig is also shown here.
