SPONSORED FEATURE Why off-the-shelf heat recovery units can be the perfect t Since the introduction of the Energy-related Products directive, the need to improve the efficiency of air handling solutions has driven demand for commercial heat recovery units that can t increasingly tight spaces, budgets and timescales. With these factors having an inuence on purchasing decisions, Jibin Kurian, national product manager for air handling units at FlktGroup UK, discusses the benets of off the shelf solutions efore Energy-related Products (ErP) legislation was introduced, heat recovery technology was often an option to accompany air handling units (AHUs) in commercial applications. Now, the requirement to comply with energy-efciency standards means that heat recovery units with air treatment capability are the norm. But as costs, timescales and space for new and retrot projects become increasingly squeezed, speciers are looking to off-the-shelf solutions to address these challenges. B Simple and standardised For projects where a simple, rather than bespoke, system ts the bill, it is possible to choose an off-the-shelf heat recovery unit, as long as the required airow rate is known. This negates the need for a technical expert to get involved in the design stage, and for complex calculations and specications, thereby simplifying the procurement process. Lead times for standardised products are shorter, enabling manufacturers to deliver their units to t tight project timescales. Once on site, installation is also much eCO Premium easier. When a project is completed, system designs and project processes featuring the same standardised heat recovery unit can be replicated for similar developments further down the line. FlktGroup offers a range of standardised heat recovery units to cater for 0.1 up to 6m3/s: the eCO PREMIUM, eQ PRIME, eQ TOP, eCO TOP and eCO SIDE. They all come fully packaged with controls that are compatible with any central BMS system; eCO units come with ISYteq mini controls, while more advanced controls are integrated with eQ products. They are all designed to plug and play, with no further programming required so after the units have been installed, only air balancing and controls commissioning need to be carried out on site. Space saving As lettable space increasingly becomes a premium in commercial buildings, architects and designers are coming under pressure to allocate minimal area for heat recovery units and their associated ductwork. This is where our eCO PREMIUM unit, with a plate heat exchanger offering up to 85% heat recovery, comes into its own. Thanks to its compact design, it can be installed into ceiling voids and connect to existing infrastructure in that area. FlktGroup offers a range of standardised heat recovery units to cater for 0.1 up to 6m3/s With all-circular connections on the short sides of the unit, lifting devices, and the ability to t through existing doorways, it makes light work of installation, to save project time as well as space. Although our eCO TOP and eCO SIDE products are not designed to t into ceiling voids, they have small footprints, with connections on the side or top to link easily to a spiro duct system. The performance of our eQ PRIME product is Eurovent certied, and it, too, has a compact design. Available in eight sizes, it allows for quick and reliable installation, with integrated controls and mounted VSDs, and cables for fast start up. Where there is no internal space for the heat recovery units, or when there is dedicated plant area on a building rooftop, products such as the eCO Premium and eQ PRIME are suitable to be located externally. These products come with high-strength, anti-corrosive mechanical 44 June 2019 www.cibsejournal.com Flakt DPS Adv from CPL.indd 44 21/05/2019 12:30
