Robust H. The high temperature causes outgassing of the PCB residue.

Farum Midtpunkt is a residential area located about 20 km north of Copenhagen. It´s famous for its peculiar, terraced houses. These houses were built between 1970 and 1974 using caulk and floor sealants containing PCB. PCB (polychlorinated biphenyl) has later been shown to be harmful both to humans and to the environment. Therefore, in Denmark, building materials containing PCB were prohibited already in 1977.

During 2009, control measurements were performed of the houses in Farum Midtpunkt, showing elevated levels of PCB in 295 individual flats caused by PCB-based caulk and floor sealants. During January of 2012, the business firm Enemærke & Petersen a/s begun a clean-up of the affected flats. This is done by heating the flats during 24 days to approximately +65 °C using electrical heaters from VEAB, model Robust H. The high temperature causes outgassing of the PCB residue. At the same time, the air is cleaned using special active carbon filters. The air quality, with regard to ppm concentrations, is monitored continuously to ensure good living conditions.

Quality and reliability are deciding factors
The decision of Enemærke & Petersen a/s to use 120 VEAB Robust H units was based on the high quality and reliability that this heater offers. Since the process must not be interrupted, the heaters must be able to maintain a constant, high temperature without any interruptions, over a long period of time. Another reason for this choice was that Robust H heaters can be put into service quickly and can be moved between different flats according to specific needs.
