The fall exhibition season last year was very busy for Blauberg Ventilatoren. The company, a member of the Blauberg Group, took part in 11 major exhibitions, each of which is a leader in the ventilation industry in its region.
Putting it in the cold language of statistics, during the 37 days of participation in the exhibitions, the company demonstrated over 50 of its own products in booths with a total area of over 240 m2. During this period, we took part in AquaTherm Almaty (Kazakhstan), HVACR Vietnam Expo (Vietnam), Bangkok RHVAC (Thailand), MARVEX Malaysia, Refrigeration & HVAC Indonesia, HARFKO (South Korea), Interclima (France), FinnBuild (Finland), Canton Fair (China), Big 5 Show (UAE) and HVAC Summit (Malta).
Focus on new technologies
A wide range of Blauberg Ventiltoren products was presented at the trade fairs: from residential fans to high-performance air handling units.
In the residential ventilation category, the trend was set by the latest innovations: the O2 and O2 Supreme, Trio and Trio One, and Qubit fans. The O2 and O2 Supreme fans are distinguished by minimum power consumption (only 2.7 W at maximum speed), high air flow (up to 140 m³/h) combined with very low noise level of 9 dBA only. This is achieved by using a modern DC motor and an aerodynamically optimized impeller.
The Trio and Trio One fans are distinguished by their low noise and energy consumption, while delivering a high air flow of up to 255 m³/h. The high-tech Qubit pressure fan is designed for long air ducts with high resistance. The specially developed centrifugal impeller of a unique design creates an air flow that is powerful enough to overcome pressure drops and maintain proper circulation of stale air in the air ducts.
The inline fans category was represented by a number of new products, including models of the inWave and Primo series. These ventilation devices are of a mixed type, which allows them to combine the extensive features and high performance of both axial and centrifugal fans. The high energy efficiency of the fans is ensured by motors with low energy consumption, including modern EC motors.
InWave sound-insulated inline fans are designed to be used in supply and exhaust ventilation systems in residential, commercial and public spaces with high noise requirements, such as educational institutions, kindergartens, offices, meeting rooms, libraries, etc. The low noise level during operation is achieved due to the special design of the internal part of the casing, the impeller and the guide device.
Primo inline fans in plastic casing feature a high air flow of up to 5700 m³/h, which makes them the optimal solution for use in ventilation systems of commercial and industrial premises where there is a need for powerful air flow.
Special mention should be made of the high-performance inline centrifugal fans in a sound-insulated casing of the Iso-VK series, designed for use in ventilation systems for large kitchens and bakeries. These devices have a capacity of up to 25,500 m³/h and are designed for continuous exhaust of contaminated air at temperatures up to 120 °C containing fats (when grease filters are used) in high resistance conditions. The fan motor is located outside the air flow and is separated from the impeller by a metal panel.
In the smoke exhaust ventilation category, the Axis-P axial pressure fan was the center of attention for the visitors. It has an air flow of up to 120,000 m³/h and is used in smoke exhaust systems for industrial, public and residential buildings as a pressure fan to create overpressure in stairwells, vestibule gateways and elevator shafts. The fan's operation prevents smoke from entering these rooms, protects people on escape routes from exposure to fire hazards, and creates conditions for firefighting operations.
Among the roof fans, the new Tower-HC series centrifugal fans, designed for use in exhaust ventilation systems of commercial, office and other public or industrial spaces, drew special attention from the audience. The fan is installed vertically on the roof directly above the air duct or ventilation shaft. The device is equipped with a two- or four-pole asynchronous motor with an external rotor and a centrifugal impeller with backward curved blades, which provides air flow of up to 2442 m³/h.
The category of decentralized ventilation systems was represented by a wide range of equipment. Particular emphasis was placed on the Freshpoint series of single-room heat recovery units with ceramic heat exchangers and the more powerful CIVIC series units.
The Freshpoint heat exchanger is the most modern solution for creating and maintaining a comfortable indoor climate in houses and apartments. Freshpoint is a full-fledged ventilation unit, which simultaneously supplies fresh air and exhausts stale air through a single opening in the outer wall. The device has a high air flow (up to 200 m³/h) and a fairly high heat recovery coefficient (up to 88%) due to the ceramic heat exchanger used. Such a heat exchanger not only keeps the room warm, but also maintains the humidity balance: at low relative humidity, it retains moisture in the room, and at high relative humidity, it removes its excess outside. The model is equipped with an intelligent control system and has a modern design of the indoor unit. With Wi-Fi, all device functions can be controlled via a smartphone using an app.
Unlike Freshpoint, CIVIC units have a higher air flow (up to 1240 m³/h), which makes them suitable for larger spaces such as school classrooms, offices and other social and commercial buildings. The devices feature quiet operation and easy installation. The installation of the equipment does not require any renovation work and takes only a few hours. The installation of the devices requires minimal interference with the structural elements of the building and does not spoil the interior of the rooms. The devices can be installed on the floor (CIVIC EC LB series) and suspended from the ceiling (CIVIC EC DB series). The heat recovery coefficient of CIVIC units is up to 96%. The ventilation units can also be controlled via a smartphone.
In the category of air handling units, we focused on our new Reneo series heat recovery units, which are designed to provide efficient energy-saving ventilation in residential, commercial and public buildings with a required air flow rate of up to 660 m³/h (apartments, houses, cottages, etc.). The Reneo model range includes Reneo S, Reneo D, Reneo-Fit D and Reneo-Fit D 100 units, which are designed for suspended ceiling, floor and wall mounting. The units have efficient counterflow heat exchangers with a high heat recovery coefficient (up to 94%). Each standard unit size is available with an enthalpy heat exchanger.
It is worth reminding that the Reneo AHU series were first presented at ISH 2023 in Germany, where they were highly appreciated by the professional audience. In addition, the Reneo-Fit model was awarded the prestigious Design Plus powered by ISH award, which is presented to products and solutions that have the optimal combination of innovation, eco-friendliness, aesthetics, functionality and industrial design.
Special attention paid to Asian countries
A special highlight of the fall trade fair season was Blauberg's active presence at trade fairs in Asia. The company's interest in the Asian market is explained by its stable growth and favorable forecasts for its further development in the coming years.
One of the major factors behind the increased demand for modern ventilation systems in Asian countries is the region's urbanization. Asia is home to over 2.2 billion people, or 54% of the world's megacities' population. It is expected that by 2050 the urban population will grow by about 50%. Thus, in the coming years, active construction of residential and commercial buildings is expected to continue, which will stimulate the introduction of ventilation equipment.
Another driver of the ventilation market in the region is the unfavorable environmental situation. Asian megacities, along with large industrial agglomerates, are world leaders in air pollution. Once indoors, dirty air causes people to feel unwell and can lead to a number of diseases: respiratory, heart, cognitive, and other conditions. Therefore, one of the sustainable trends in the coming years in the region will be the growing interest in filtration technology, in particular, ventilation systems with HEPA filters, carbon filters and fine filters that can provide clean air to the rooms.
Energy saving is another important factor in the growing interest in energy-efficient ventilation equipment in the region. Air handling units are among the largest consumers of electricity in buildings after cooling and lighting systems. In order to reduce operating costs and save energy, Asian consumers are increasingly shifting their focus to energy-efficient and energy-saving ventilation systems. The use of equipment with heat recovery will also reduce the load on air conditioning systems and, consequently, their costs.
Another incentive for the active implementation of ventilation systems in the Asian region was the COVID-19 pandemic, which revealed the importance of high-quality air exchange in enclosed spaces. Studies have shown that the transmission of coronavirus infection was particularly effective in crowded enclosed spaces with poor ventilation. The researchers concluded that a constant supply of fresh air and extraction of stale air can lower the concentration of viruses in a room and increase the time required for an infectious dose to be absorbed.
Participation in the trade fairs of the fall campaign enabled us to present our latest developments in various regional markets and exchange experience with leading industry experts. Thousands of visitors of our booths had an opportunity to see that Blauberg Ventilatoren's product range meets the needs of any customer and provides comprehensive solutions for any facility, from small apartments to large industrial and commercial buildings.
