Lindab's new VAV system Pascal, is now increasingly starting to appear in contexts where energy-efficiency, simple installation and flexible adjustment are important parameters. Along with its 130 or so pupils, Ramlösa Friskola moved into its completely new premises just outside Helsingborg before the start of the spring term. “We have been located here on Magnoliagatan since 2003, but had felt for over a year that we had grown out of the premises,” says Mikael Meviken at Ramlösa Friskola. “We rented school modules from a company called Pamil, and it was also Pamil that gave us the best solution for our new school building. It is still a modular building, but with a completely new sense of harmony and well-being that both pupils and teachers, as well as parents, appreciate. Furthermore, we have acquired an energy-saving and completely silent ventilation system, which clearly contributes to our sense of well-being.”
Pamil Modulsystem has been manufacturing, letting and selling flexible modular buildings for exactly 50 years (congratulations!), with the focus on offices, schools and nurseries. For many of these years the company has also used Lindab as supplier of both ventilation systems and construction components in the form of exterior cladding, roofing
profiles and roof drainage etc. “Lindab’s duct system and diffusers are in just about all the modular buildings we have manufactured in recent years,” explains Claes Bengtsson, CEO of Pamil. “In line with the ever increasing focus on energy-efficiency, we also started looking at more energy-saving ventilation solutions. Lindab launched Pascal, its new VAV-system, while we were designing the Ramlösa Friskola, and it proved to be ideal for our requirements in this area.”
“We wanted to achieve a modern, demand-controlled and energy-efficient ventilation system, and that’s exactly what we have got with Pascal,” Claes Bengtsson continues. “As usual, Lindab has given us excellent technical support and service throughout the entire process, and installation, assembly and adjustment has proceeded without any problems. The Pascal system also enables both the fan unit and ducts to be downsized, which reduces both the investment- and running costs, so there are numerous benefits.” Motion sensors on the actual diffuser, along with CO2 gauges in rooms, ensure that the Pascal system provides satisfactory ventilation when it is really needed. Besides the visible, active Pascal diffuser, the system consists of the specially developed MBBV boxes and Regula control units.
Pamil normally carries out its own manufacturing and construction, but for somewhat more complex ventilation systems such as this, it engages subcontractors for design, installation and adjustment. The duct system is usually also installed during the actual manufacture of the modules at Pamil’s large plant in Helsingborg. In this case, with a more complex installation, the Lindab Safe duct system was installed on site, after the modules had been transported there and assembled. Pamil leases the complete school facility to Ramlösa Friskola.
“The new school building has actually only been in use since early January,” Claes Bengtsson continues, “so we haven’t been able to monitor energy consumption yet, but it is absolutely clear that a VAV-system of this type uses less energy, and utilising these types of modern solutions in our module complex feels great, both environmentally and economically.” Mikael Meviken and Ramlösa Friskola take a very positive view of the development of the new school. “There are clear indications that we are increasing our attractiveness and we are observing a stable increase in our school population. A comfortable and harmonious environment, with a good indoor climate, is no doubt proving attractive!”
