In the coming months, Maru Metall will produce the steel structures and cladding for the Patola heating plant project in Helsinki, with Maru THM handling the installation. This large-scale project was commissioned by the Finnish energy group Helen OY.

The Patola heating plant complex is scheduled to become operational during the next heating season. It is a technologically significant project featuring an industrial-scale heat pump and two 50 MW electric boilers. The air-to-water heat pump plant being constructed is one of the largest in the world – designed to operate in outdoor temperatures as low as -20°C, utilizing carbon dioxide (CO2) as a natural refrigerant.

This project further builds upon our extensive experience in manufacturing and installing steel structures for the Finnish energy sector.

The list of Finnish heating plants featuring Maru-produced steel structures is substantial, ranging from Leppävirta and Turenki to Turku, Lahti, and Imatra. The Patola project confirms the capability of Maru’s units to deliver complex solutions in a demanding international market.
