The CPD follows Rinnais report into hydrogen as a clean source of energy, which can be accessed free at www.rinnaiuk.com and is available in hard-copy or PDF formats. Rinnai offers a range of CPDs for designers, reducing cost and CO2. Rinnai, through its CPD and training programmes, aims to engage with the market to assist decision-making and understanding of the different messages faced by todays engineers, installers and designers. Chris Goggin, operations director, said: We can demonstrate how innovation can reduce the burden on fossil fuels while maximising renewable gains.

The upgrade, which was done in one day, ensures long-term protection against corrosion and reduces AHU fan energy consumption by 25-30%. Built-in redundancy also prevents hulled, screw propeller-driven, steam-powered passenger liner, and in the early 2000s Munters was part of a wider project to preserve the hull. This included installing a specially designed AHU, with Munters desiccant rotor technology, in the dry dock. Looking after the ship and conserving the original iron is the most important thing that we do, said Nicola Grahamslaw, conservation engineer for SS Great Britain. By ensuring the air around the ship is kept at 20% relative humidity, we can stop the ship from rusting. This keeps her structurally safe for many years to come. With the belt-driven fan coming to the end of its expected life, Munters has upgraded the AHU with three electronically commutated (EC), direct-drive plug fans from ebm-papst. It designed a bespoke bulk head so the new fans could be brought in in component Tel: 020 7880 6245 Email: cibsedirectory@redactive.co.uk CIBSE Aug 21 pp61-64 Products.indd 61 ships control system. Minimising downtime to a single day was critical to prevent the ship being exposed to humid air. Greg Frazer, of Munters service sales, said: This upgrade brings cutting-edge technology disruption. There is little maintenance, and predicted energy savings for the fan are 25-30%. The SS Great Britain Trust has committed to reach net-zero carbon emissions by 2030, and conserving the ship is one of the biggest energy consumers. What you do has to be sustainable, said Grahamslaw. Every time we tweak the system, we are thinking about our carbon footprint, and learning how we can make that energy requirement as small as we possibly can on our journey to net zero.
