The latest technology for the winter period – Large space heaters from Wacker Neuson

The Turkish-Italian construction industry joint venture IC İçtaş-Astaldi relied on the innovative heating technology of the Wacker Neuson Group for the interior work of the third terminal of the St. Petersburg-Pulkovo International Airport.

Eleven heaters of the type HP 252 were used when constructing the third terminal for the St. Petersburg-Pulkovo International Airport, a construction site with sometimes up to 2,000 workers per day. The heaters ensured that the interior work could be continued, despite icy outdoor temperatures of around minus 20 degrees Celsius – which is an invaluable advantage for large projects of this kind on a tight schedule. The innovative, environmentally friendly and energy-saving hydronic system of the HP 252 is unique for the construction industry in the Russian market and was previously largely unknown. 

"Direct oil-fired space heaters were initially planned. However, once we learned about the heating technology of Wacker Neuson, we carried out a comparative analysis of both offers. This proved the HP 252 to be a more convenient and compact solution," says Nahfuz Yilmaz, director of the structural engineering department of IC İçtaş-Astaldi, a joint venture between the Turkish construction company IC İçtaş and the Italian construction group Astaldi. The HP 252 offers a high level of comfort and flexibility through the fact of being able to connect up to 16 heat exchangers to the central heating unit. Depending on the size, these end devices can be carried or moved by one person and can be placed anywhere in the building where heat is needed. They work according to the principle of liquid-to-air heat exchangers and therefore provide dry and completely clean, zero-emission heat. Unlike direct heaters, they can therefore be operated in confined spaces as well as without any health risk to the workers. The heat exchangers are connected via thin hoses with a central, diesel-operated heating unit positioned outside of the building. The hoses are fed through very small openings in the building. Heat losses from incoming outside air are therefore reduced to a minimum and the heating efficiency is increased. 

The high efficiency of the hydronic system as well as the low heat loss from use in closed spaces lead to substantial savings with the fuel consumption of the burner – up to 50 percent compared to direct or fireplace heaters! This represents significant operating cost savings, which are continuously added up throughout the service life of the HP 252. 

When setting up the eleven large space heaters on the airport construction site, technical specialists from Wacker Neuson were on-site to train the employees how to operate the equipment and to perform the initial maintenance. "We are completely satisfied with the quality of the equipment and the service of Wacker Neuson. This high quality technology absolutely meets our requirements in terms of productivity and quality," says Nahfuz Yilmaz.
