New Products New condensing boiler suited for retrofit
Web platform for monitoring, control Carlo Gavazzi has launched the UWP 3.0 Edge universal web platform designed for monitoring and control of energy management systems, building automation and car park guidance functions. Powered by MAIA Cloud, it provides a secure and reliable system for remotely managing, setting and operating UWP 3.0 units worldwide as well as providing IoT cyber security rating by UL to Level SILVER for UWP 3.0 SE (Security Enhancement). The 2 DIN wide UWP 3.0 Edge easily manages up to 5000 managed signals (including variables, I/Os) which could be shared among energy management, building automation and car park guidance applications, up to 128 Modbus devices connected to RS485 ports (64 devices each port), up to five users concurrently connected to the Web-App, up to 5 concurrent M2M connections (API connections, BACnet clients, Modbus masters), up to 150 different products from the Carlo Gavazzi range can be connected to UWP 3.0 and is BTL certified (max 500 BACnet points for used BACnet objects). The customisable built in webserver provides the opportunity to display data, build charts, set alarms and control the system, which can be accessed locally or remotely anywhere in the world. New additional operational functions include a backup system, a smooth upgrade procedure and the UCS to UWP 3.0 bridging function for configuration of meters remotely.
Enhancements for power analyser Yokogawa has launched a new Current Sensor Element and upgraded the firmware for its WT5000 Precision Power Analyzer. The enhancements are designed to help companies improve performance when developing or evaluating electronic devices such as Electric Vehicle (EV) related equipment or systems for solar and wind power installations. The new Current Sensor Element runs off the internal DC power supply of the WT5000, making external power supplies unnecessary. This makes set up for measurements easier as the only things required are the current sensor and a connecting cable. Three sensor connection cable lengths are available - 3m, 5m and 10m. This helps take account of varying test bench layouts, where the power analyzer may not be located right next to the device under test. The three different cable lengths allow users to select the one most suitable for their set up while keeping the leads as short as possible. Firmware is also upgraded, with the Data Streaming function now supporting a 50 ms to one second update rate. On the previous version, when using the Data Streaming function, the WT5000 only offered an update rate - measurement interval – of one second. This meant that all electrical parameters, such as power and Urms and Irms, were calculated over a period of one second.
Ariston has added the Clas ONE R to its ONE Series range of condensing gas boilers. Replacing the Clas HE R, the new regular boiler is quiet and compact, as well as a great retrofit product for use in an open vented system. It has an impressive, modern design, complete with a large backlit display, offering a wealth of energy-saving features. Available as the Clas ONE R 24, this new boiler shares many of the advanced features for which Ariston’s ONE Series is renowned. These include the patented stainless steel, continuous coil proprietary XtraTech heat exchanger, complete with 40 per cent wider waterways, alongside low NOx ratings (53mg/kWh). The boilers are also ‘A’ ErP rated for optimum energy efficiency and, for added peace of mind, are supplied with an 8-year manufacturer’s warranty as standard. The wider waterways of the XtraTech heat exchanger allow water to pass through quicker and more effectively – ensuring less risk of blockages from debris. The component is robust and operates well in a wide range of pH values. Easy to use and install, the new regular boiler benefits from Ariston’s ‘Auto’ function technology, which gradually increases a system’s water temperature until the central heating has reached its target. When used in conjunction with the company’s extensive range of controls, this function guarantees no excessive peaks in flow temperature, ensuring greater levels of comfort, as well as reducing energy bills.
Fan coil unit to help drive to net-zero Aermec has unveiled a new fan coil unit that only uses three water pipes and is aimed at helping customers achieve near zero energy buildings. The 3WP system launched at Mostra Convegno’s on-line MCE event provides the advantages of refrigerant-based VRF systems with four-pipe hydronic FCUs. Traditional two and four-pipe hydronic HVAC systems are widely used, but Aermec’s three-pipe system uses less pipework, requires less investment and reduces the costs of installation. The 3WP offers a cost-effective HVAC solution as one of the key benefits is that it offers greater flexibility in system capacity and distances, it is also easier to design and repair which reduces overall costs. The 3WP system ranges from 40kW to 400kW in a single unit and up to 950kW in a cascade. The system’s internal heat exchangers operate on an extra elevated high ∆T and a significantly reduced mass flow. Compared to previous technologies the performance and efficiency has significantly increased without compromising the thermal capacity. Aermec’s 3WP has already been installed in an hotel in Milan, Italy, where it has delivered significant savings: • 29 per cent savings in installation costs; • €4,010 annual reduction in pumping energy costs (5-7 per cent less energy) • enhanced efficiency of the heat pump due to mild temperatures (± 10 per cent higher SCOP / SEER) ENERGY IN BUILDINGS & INDUSTRY | MAY 2021 | 15
