BELIMO, a renowned manufacturer and distributor of electric actuators for motorised control devices in heating, ventilating and air-conditioning (HVAC) systems, reports very encouraging response to the new “green-friendly” products it launched at the Big 5 show last year.
The new products that adhere to the green buildings code include its fan optimiser for VAV (variable air volume) systems and pressure independent control valves for chilled water applications.
“The market response to these products has been very good and we have already supplied them to a number of prestigious projects in the UAE,” says David Stevenson, general manager – Middle East, Belimo Automation, the Middle East subsidiary of Switzerland-based Belimo. In line with its strategy to develop new cost-effective products, Belimo innovated the COU24-A-MP, a new, power-saving way to control fans in a VAV system, according to Stevenson. “Thanks to the Belimo fan optimiser, COU24-A-MP, fans can be controlled based on demand according to the damper positions of the downstream VAV units. Supply pressure regulation – presently the standard method – can thus be dispensed with and fan energy consumption cut by as much as 50 per cent. Costs will thus be cut substantially and the convenience for users increased.”
“The first project in line with the green buildings directive using the unique Belimo fan optimiser for a VAV system has been commissioned in Dubai International Financial Centre (DIFC), Dubai. The system will guarantee up to 50 per cent energy savings compared to a conventional system,” he adds.
In the same vein, Belimo’s latest valves, according to him, redefine technology standards. “The efficiency of the pressure-independent and the low-cost control valves with their unique disc that guarantees an equal-percentage characteristic curve has been proven millions of times over in practical use.
Other innovative products recently launched by Belimo include the Trade Selection range of products, which consists of a low-cost two- and three-way zone valves, together with digital room temperature controllers suitable for fan coil units and VAV control systems. The range of control valves has been supplied to projects such as Al Barari Villas, Oasis Shopping Mall, Al Majiz Tower, Millennium Hotel in Dubai and Park Rotana in Abu Dhabi, among many more.
Belimo has also recently introduced a range of isolation and butterfly valves that are described as being ideal for all shut-off and control tasks in cooling circuits with small to large flow. The valves in the A6 and D6 N range are designed for standard applications and feature a robust epoxy coating on the valve body and a stainless steel disc.
Commenting on some of the highlights of the products, Stevenson says: “These high-quality valves offer amazing value for money. They are designed to resist extreme medium temperatures, from –20 deg C to 120 deg C (or peaks of 130 deg C for up to one hour). Due to their tight-sealing closure, they make an important contribution to preventing energy losses.
“Since pressure classes PN 6/10/16 is integrated in the flange dimensions, stock-keeping is reduced. This apart, the high quality of materials used and high standards of production ensure that the butterfly valves have a long service life – they will function reliably for many years without the need for any maintenance.”
The range covers the nominal width between DN25 and DN350 with flow rates (kv values) from 45 to 10,900 cu m per hour. The valves can be supplied with a lever or a worm gear for manual operation or with a wide selection of Belimo electric actuators for motorised applications.
Belimo also offers safety solutions such as its Monico fire protection monitoring system. This turnkey system solution for motorised fire dampers is a future-oriented investment offering maximum safety at a good price and performance, according to Stevenson. The Monico system consists of a digital automation station with display for the control and monitoring of motorised fire dampers. Data is transmitted via the proven Belimo MP-Bus, while up to eight fire dampers can be connected to each automation station. The system can be flexibly extended with slave stations for larger objects.
Belimo has supplied numerous fire and smoke actuators for the prestigious Burj Dubai and Dubai Metro elevated stations.
Meanwhile, Belimo’s Robust Line actuators are described as being ideal under extreme ambient conditions, ensuring corrosion-free and absolutely tight — IP66/67 protection.
“In animal breeding as well as in indoor swimming pools, the agriculture and food industry or in roof installations – the Robust Line actuators from Belimo remain corrosion-resistant and absolutely tight under even the harshest of conditions. Clamps made of stainless and acid-resistant steel or form-fits made of high-quality aluminium ensure a perfect spindle driver – both for air control devices as well as for valves. The interior of the housing also provides room for the installation of components on the customer side, such as a relay or controller,” Stevenson points out.
Since 1975, Belimo’s innovative, high-class technology ensures trouble-free operation for all kinds of HVAC control devices, he points out.
“This not only means greater comfort and convenience, but also greater safety for property and the occupants of buildings,” Stevenson points out.
Belimo’s Middle East office and warehouse, located in Dubai Airport Free Zone, stocks a full range of air and water products.
Products are supported by a dedicated sales team offering comprehensive technical and after-sales service. Seminar presentations on VAV, fire and smoke control, energy saving and many other subjects associated with its product range are available at either its new training facility or at the customers’ own premises.
