We are extremely proud of the projects we have been involved in
and take great pride in our work. Here are a few customer
comments about recently completed works.
"The replacement Primary Monitoring Tanks supplied by RR/NES
(Rolls Royce Nuclear Engineering) were of a high manufacturing
standard and a credit to their sub-contractors Britannia Heat
Transfer" - Magnox Electric plc (Bradwell Power Station)
"From our initial enquiry to the completion of all works as
requested, your staff have completed their work both efficiently
and to a very high standard. Furthermore, I was pleased to see
that [your employees] complied with Nuclear Site Rules and
Regulations to the full and promoting your company further by
maintaining tidy working conditions and leaving the work area
spotless upon completion of works." - Magnox Electric plc
(Sizewell A Power Station)
"The site team performed exceptionally well, demonstrating their
skill while working safely at all times and by meeting their
programme dates. I would also like to thank you for the way you
responded to the tube delivery problem, providing alternative
tubes at short notice, enabling us to meet our schedule startup.
Without your help we would have incurred significant generation
losses, in fact I feel we have achieved a better solution with
the fitting of the alternative Titanium tubes." - Corus (Redcar
Power Station) |
A large Rotterdam based ship owner had 7 particular vessels with
Diesel United main engines which had always suffered high
pressure drop across the original air-coolers (from 225mm WG
when new to 440mm WG after short service), due to fouling
blocking the airside fins. This necessitated regular ultrasonic
cleaning as other associated equipment was also affected. New
air-coolers were designed using ElfinBlock cores which not only
matched the performance of the original units, but also reduced
pressure drop to 160mm WG which then remained significantly
lower, even after extended running times. The initial trial
units were subsequently rolled out to the remaining 6 vessels.
Fuel consumption was subsequently improved as the engines
performed better with greater and cooler quantities of air to
the engines.

A UK power station required 48 Generator Air Coolers due to
stress corrosion and fatigue at the tube plate joint on the
original coolers. Replacement units were designed and
manufactured using Admiralty Brass tubes and Aluminium
ElfinBlock. These units were thermally and mechanically designed
in-house using software which had been tailored to incorporate
the enhanced performance inherent to the ElfinBlock core. The
superior performance and efficiency levels provided by these
coolers (temperature drops in excess of 12%), combined with
reduced water flow requirements (compared to both the original
coolers and the generally available alternatives) has increased
the time between motor re-winds, the benefits gained far
exceeding the outlay of the coolers.
A nuclear station located on the UK coastline was suffering
extremely short service life from a range of essential coolers,
including Generators Diesel Engine Coolers, Jacket Water
Coolers, Lube Oil Coolers and Inter-Coolers. It was apparent
that these premature failures were due to the erosion of the
tubes caused by the high levels of sand in the cooling water.
Britannia Heatex a wholly owned subsidery of Applied Cooling
Technology ltd designed new tube bundles using Titanium tubes
and tube plates. These replacement units have now been in
service for 9 years, compared with the previous units which
generally failed within 1 year.
Another UK nuclear station was encountering problems with a Gas
Circulator Motor Air Cooler due to the sand in the cooling sea
water eroding the copper nickel tubes, resulting in failure
within 2 to 3 years from commissioning. A redesigned unit was
manufactured using ElfinBlock consisting of Titanium tubes and
copper fins, which has, to date, lasted 6 years and we have no
reason to believe it will not last for many more. |
