34 MODERN BUILDING SERVICES APRIL 2023 WHAT’S NEW A guide to new products and services for MBS readers Modutherm’s Nordflex+ controller provides optimum systemefficiency Following the successful launch of its range of high efficiency heat pumps, Modutherm has introduced the NordFlex+ Wi-Fi controller. Designed specifically for use with the company’s range of AWMonobloc heat pumps, the NordFlex+ is BMS compatible and allows up to 16 units to be operated from one device. Controllability is further enhanced by its remote monitoring capabilities, with the operating parameters also easily accessed via a mobile app. The NordFlex+ uses cascade logic to ensure the heat pump system always achieves the highest COP. The controller manages the compressor speed of all the heat pumps in a system to maximise efficiency in line with heating demand. This ensures the running time (and fuel consumption) of the heat pumps is evened out for optimum system efficiency and reliability. A single “daisy chain” data cable creates a control network of heat pumps and NordFlex+, so an isolated power supply to each outdoor unit minimises cable installation. The controller is capable of simultaneously handling up to four mixed heating/cooling circuits with different temperature zones. This is achieved by prioritising the heating circuit with the highest heating demand to run the system, while adjusting down to the temperature for the rest of the circuits simply by controlling the mixing valves. All the necessary settings can be easily adjusted on the touchscreen display, enabling the creation of simultaneous cooling, heating and DHW production. A key benefit of the NordFlex+ is its multifunctional control capabilities, allowing it to be designed into a huge range of projects without the need for any additional programming. To simplify commissioning, engineers can preconfigure the control to suit a building’s heating system, so it is ready to use when it arrives onsite. As it is designed for hybrid systems, it works with a range of additional heating technologies and systems, including boilers, district heating networks and heat pumps. Indeed, using the NordFlex+ controller’s configuration tool allows for the creation of a hybrid, flexible and futureproof system, incorporating heat pumps and other energy sources. With the addition of an expansion board, it can even connect multiple buildings such as factories, offices and housing, as well as create a small district heating grid, also known as a ‘microgrid’. www.modutherm.co.uk . Combat launch range of Elite ProUnit Heaters Combat Heating Solutions, Europe’s leading developer and manufacturer of energy efficient warm air heating and radiant systems, are delighted to introduce you to their range of Elite Pro Unit Heaters, Models EPU 30-115kW, one of the most effective energy reduction technologies available on the market. At Combat we are committed to designing, developing and delivering innovative energy efficient and effective products and system solutions, which is why our range of unit heaters has received a make-over and are available in several sizes. Our new Elite Pro range of warm air unit heaters now offer even greater energy efficiency combined with quiet operation. The new range are easy to install, maintain and operate with a wide range of options. Suitable for either room sealed or open flued installation, the heaters also have lockout indicator lights help to make troubleshooting easier. The new range now benefits from fully modulating burners for greater efficiency and stainless heat exchangers as standard for long life. In addition, the heaters can be suspended or shelf mounted, freeing up valuable workspace and providing flexibility with several air handling options, such as axial, centrifugal fan or ducted applications. Additional benefits include; • Fully modulating burner • Heater status indicator lamps • Room sealed or open flued installation • Operated using Combat NRG controller • Suspended or shelf mounted • Remote fan operation for summer air circulation facility All of our warm air heaters are 100%manufactured in the UK, produced from start to finish at our lean operated manufacturing facility in the heart of the West Midlands in Wednesbury. www.combat.co.uk
