NEW PRODUCTS EPD DECLARATION


Reinforcing commitment to sustainable HVAC


DAIKIN has launched an Environmental Product Declaration (EPD) for its VRV5 Heat Recovery R32 system, emphasising its commitment to sustainable HVAC systems. The EPD provides quality-assured, quantifiable environmental data for the VRV5 Heat Recovery R32 system, providing assurance to building designers, planners, contractors, and developers that Daikin's products align with their sustainability goals. The company claims this EPD sets a new standard for the industry by promoting transparency in carbon emissions reduction and energy efficiency. Matteo Dall’Ombra, product manager


commercial at Daikin UK, says: “Transitioning to more sustainable products is a key priority for Daikin. The introduction of the EPD is concrete

ADVECO has introduced the Chilled Water System (CWS), a range of premium carbon steel tanks designed for commercial cooling applications. The CWS tanks, available 10 models ranging from 300 to 5,000 litres, are suitable for storing chilled water in systems such as heat pumps, chillers, and fan coil units. The CWS tanks feature large


connections at high and low levels, providing versatility for moderate to high flow rates and compatibility with multiple cooling sources. With dual-layer insulation, including an anti-condensation underlay and 100mm of outer insulation, the tanks ensure optimal temperature control and prevent condensation. Designed with a low maximum


height, these tanks are easy to install in plant rooms with limited clearance. They incorporate internal partitions for improved stratification and prevent preferential flows. The outer insulation

AIR-TO-WATER CHILLERS Sustainable comfort and process cooling


The Aries N air-to-water range from TRANE is a new generation of chillers designed to provide a sustainable alternative to old refrigerant systems. They utilise natural refrigerant R-290 (propane) with zero ozone depletion potential and a low global warming potential of 0.02. They are said to offer ‘excellent’ thermodynamic and energy efficiency capabilities in cooling capacities ranging from 175 to 335kW. By using R-290, customers can reduce


direct and indirect emissions by using less refrigerant charge per kilowatt of cooling capacity, combined with higher seasonal efficiencies. Trane says the use of R-290 also


provides tax benefits in many countries and is exempt from the fluorinated

refrigerant phase-down programme in the EU. These chillers feature a dual circuit design, EC fans, electronic expansion valves, and semi-hermetic inverter- driven compressors, ensuring efficiency across varying cooling demands. Optional features include Partial Heat Recovery and Super Low Noise functionality. The Aries N chillers are suitable for industrial process cooling applications, such as food and beverage or pharmaceutical production, as well as commercial HVAC systems. They are aimed at HVAC consultants, design contractors, and facility managers seeking sustainable and efficient


comfort cooling solutions. ■ www.trane.eu


With the introduction of the TVE series, TROX says it has presented for the first time a completely new measuring principle for precise detection of the differential pressure and automatic control of the volume flow rate. Now the circular-duct TVE is followed by the matching sister model TVE-Q for rectangular ducts. In typical air terminal units, the


differential pressure is measured by means of measuring probes in the ventilation duct. Here, both the airflow direction and a sufficient upstream duct length must be observed for accurate measurement results. This is not required with TVE-Q. The innovation from TROX is that


the differential pressure is measured directly via the damper blade. The patented measuring principle has now been transferred to the rectangular TVE-Q variant. The damper blade shaft is hollow and a central duct transmits the differential pressure to the transducer,


which is directly integrated into the controller casing. This measurement principle enables accurate readings even at low air flow velocities < 1 m/s. The advantage of this is that, by eliminating measuring probes, external hoses or sensors, an extremely compact design is achieved, which allows easy installation even in tight spaces - in the case of dynamic measurement, air flow can pass in either direction. Even with static measurement, the installation position is flexible. As no upstream or downstream lengths are necessary, the terminal unit can be mounted directly on a branch or after bends. A one-piece housing design ensures


reduced leakage, high efficiency, and easy cleaning, conforming to VDI 6022


hygiene standards. ■ www.troxuk.co.uk

The CWS tanks are suitable for


standard working pressures of up to 6 bar, with 10 bar versions available for projects requiring higher pressure, such as multi-storey buildings with basement plant rooms. Multiple sensor pockets allow for easy integration of controls or BMS sensors, while an inspection/clean- out flange enables convenient service and maintenance. The Adveco CWS range is described


as offering a cost-effective solution that meets the majority of cooling system requirements, eliminating the need for bespoke cylinder manufacturing. The tanks can be seamlessly incorporated into packaged plant rooms, leveraging the benefits of offsite construction for improved system quality and faster


installation. ■ www.adveco.co
