Systemair announces supplying smart, sustainable HVAC solutions for Expo 2020
DUBAI, UAE, 11 October 2021: The Systemair Group, as official sponsor of the Swedish Pavilion at Expo 2020, from October 1 to March 31 in Dubai, will showcase modern climate solutions from Systemair and Frico that, it said, will ensure visitors to the Pavilion are able to breathe clean air and enjoy the cool climate in a smart and sustainable manner. Announcing this through a Press release, Systemair Group added that Systemair and Frico will also be organising several exciting events aimed at educating stakeholders on the importance of achieving optimum indoor air quality without compromising on energy efficiency.
Morten Schmelzer, Technical Marketing Director, Systemair Group, said: “As proud sponsors of the Swedish Pavilion, we want to ensure visitors can benefit from healthy and comfortable indoor climate. Keeping this in mind, we have carefully selected the products that will ensure fresh air supply, which is especially crucial in view of COVID-19. Our solution also offers a minimum of 50% lower electrical power consumption and sustainable cooling recovery as high as 65%, which is unique for the Middle East. Lastly, the products are in line with the latest high European and ISO standards, which enable the best possible IAQ with minimum energy utilisation.”
Systemair Group said it supplied 10 of its high-end Geniox AHUs with state-of-the-art control systems to meet requirements of the local ambient conditions, as well as the spatial challenges posed by the unique design of the structure. It said it also supplied a sorption cooling recovery system with special material on the heat-recovery wheel, along with fan-coil units, a Sysaqua 170 chiller and a roof fan – the DVG EC560. The pavilion features two of the latest-generation air curtains from Frico, installed in the shop and the cafeteria, it added.
According to Systemair Group, Systemair and Frico will hold a VIP keynote event and reception night during the Expo, featuring leading global experts, who will discuss trends and innovations relating to the next generation of sustainable HVAC technologies. Also in the information dissemination mix, Systemair Group said, is an exclusive workshop that will elaborate on how stakeholders can leverage advanced technical solutions to obtain healthy indoor air in their projects while saving energy in their projects.
Dunli launches X-Pro axial fans
Yuhang District, Hangzhou, Zhejiang, China 3 May 2021: Dunli has launched the X-Pro series of axial fans, which the company described in a Press release as designed to feature the latest rear guide vane and three-dimensional flow impeller.
The range covers a variety of impeller diameters, including 500mm, 630mm, 710mm, 800mm and 900mm, Dunli said. The maximum static pressure efficiency is up to 56%, and the air volume is as high as 35,000m3/h, the company claimed. The noise and range – throw distance – are able to perform significantly better than the equivalent fans from the motor fan industry all over the world, the company further claimed.
According to Dunli, the X-Pro fans can be used on a variety of HVAC equipment, such as air coolers, air-cooled heat exchange modules, heat pumps and cooling towers. This X-Pro series, Dunli said, is reliable, lends itself to easy installation and maintenance and is convenient to control.
Carel launches pCOe
BRUGINE, Padua, Italy, 22 April 2021: Carel said it has widened its range of I/O expansions in the first part of 2021 with the development of a new digital input expansion board. I/O expansions are modules that can be added to a typical air conditioning application, to increase the number of inputs and outputs available on the controller and, consequently, optimise the flexibility and modularity of the solutions, the company explained through a Press release for the purpose of making the announcement of the launch.
Carel said one of the most common uses of the digital input expansion board involves ventilation sections comprising several fans with electronic motors; in this case, the speed of the individual devices needs to be monitored in order to check their operating status and act on the other fans accordingly, if one of them fails. Carel said it has for many years now offered all of the tools needed to support large systems, such as air-handling units or dry coolers, in which the fans are equipped with electronics that communicate via Modbus®, making it possible to directly monitor their operating status.
However, units that are smaller in size and capacity have simpler and more economical fans that do not feature serial communication and provide a pulse signal based on the rotation speed, which can be read by fast digital inputs, Carel said. This is the basis for the development of its new digital input expansion board, which the company described as an ideal solution for all cases where numerous digital inputs – including fast inputs up to 500 Hz – need to be read, however, while limiting the total number of I/Os and space required, adding only those that are needed.
One typical example involves so-called “in row units” used for cooling data centres. The highly compact units do not require complex device control architecture or specific sensors for their operation, Carel said. These feature a single ventilation section with at least eight fans in parallel, which need to be monitored individually. In this case, reading the signal is a simple and effective way to verify operation, as well as being a more economical solution than installing expensive air flow-rate sensors, Carel said.
The new expansion board, Carel said, features a high number of digital inputs to ensure maximum flexibility in different applications. This is essential on units where the main controller features a limited number of inputs and outputs, while multiple digital inputs need to be connected, for example to detect alarms or various signals.
The entire range of I/O expansions, Carel said, can be integrated into solutions based on the CAREL pCO and c.pCO programmable controller platforms, or into architecture using different controllers.
