The upgrade, which was carried out in just one day, ensures long term protection against corrosion, while reducing AHU fan energy consumption by 25-30 per cent. Brunel’s SS Great Britain was the world’s first iron hulled, screw propeller-driven, steam-powered passenger liner. In the early 2000s, Munters was part of a wider project to preserve the iron hull, which included the installation of a specially-designed air handling unit (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, ship’s conservation engineer for Brunel’s SS Great Britain. “By ensuring the air around the ship is kept at 20 per cent relative humidity, we can stop the ship from rusting. This keeps her structurally safe for many years to come.” More than 15 years on and 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. Munters designed a bespoke bulk head so the new fans that could be brought in in component form, flat packed, and retrofitted in a fan wall configuration and digitally integrated into the ship’s control system. Minimising downtime to a single day was critical to prevent the ship being exposed to humid air. Greg Frazer, Munters service sales, said “This upgrade brings cutting edge technology into the original dehumidifier with minimal disruption. There is little maintenance, and predicted energy savings for the fan are 25-30 per cent.” Watch the video at https://bit.ly/35Z5q6W and visit the Munters website at https://bit.ly/3hm1F0z. CIAT INTRODUCES CLIMACIATPOWER AHU RANGE WITH HIGH- EFFICIENCY HEAT RECOVERY OPTION CIAT has extended its range of air handling units (AHUs) with the addition of higher capacity units with the option of high-e ciency heat recovery. The new CLIMACIATPower units are designed to allow for applications on larger projects and buildings. The Eurovent-certified units, available in capacities up to 41 cubic metres per second, have industry leading ratings for casing strength (D1) and leakage rates (L1) with the option of integrated onboard controls, enabling quick and easy installation onsite. All CLIMACIATPower units can be specified with high-performance heat recovery, improving energy e ciency by capturing energy from the exhaust airstream that would otherwise be lost, and returning it to the building through a high-e ciency plate heat exchanger with optional supplementary heating or cooling medium. The unit’s casings are made of stainless steel panels and aluminum profiles treated with interior and exterior lacquer, and insulated with thermo- acoustic mineral wool with weights up to 40 kilograms per cubic metre. Unit construction is P 160/50 PS TB. The new large-capacity units are available in five configurable presets and are suitable for a multitude of project sizes and applications. The optional integrated control system enables local, remote control and monitoring via an intuitive and customisable interface. https://www.ciat.uk.com/type/air-handling-units/ LG LAUNCHES HYDRO KIT FOR DOMESTIC HOT WATER LG has launched a new wall- mounted hydro kit for the production of hot water in domestic and small commercial/retail/o ce applications. The indoor unit can connect to LG Multi V VRF Systems – Multi V 5 and Multi V M, Multi VS and the R32 Multi VS Compact units. It utilises wasted heat from cooling and transfers this to the hydro kit for the production of hot water. It comes with a water flow temperature for heating of a maximum of 50°C and cooling temperature of a minimum of 5°C. The hydro kit comes in a range of sizes from 5.5 kW-9 kW and is compatible with low GWP R32 refrigerant, incorporating integrated water side components to reduce installation time and cost, and o£ers significant space saving benefits and easy maintenance. The kit can be used with the heating priority function that provides initial cost saving and user convenience. Also, domestic hot water is always available, even during the cooling season without manual mode changes. The intuitive user interface is easy and quick to use and users can set schedules based on their lifestyles. Daily or monthly power consumption monitoring allows for e cient energy management. Users of LG’s ThinQ app can control the cooling remotely. www.lg.com/uk/business/inquire-to-buy TBrunel’s SS Great Britain in Bristol Fan wall configuration
