Diemlach/Wartberg

The Diemlach plant, formerly part of Vogel & Noot Wärmetechnik AG has been operating since May 2007 under the new legal entity of “Rettig Austria GmbH”.

This Austrian site covers more than 30.000 m², of which 15.000 m² comprises Production and Warehouse buildings. With 100 employees, annual production runs close to 200.000 pieces for bathroom radiators, convectors and design radiators available in Round and Flat tube formats.

A high level of automation is reached in the Diemlach plant. Production equipment starts with the cutting, bending and closing of the different tubes.  Welding assembly operations follow before leakage tests, chemical pre-treatment (the ATL-base lacquer,) and powder coating in the different oven areas. The final step is the packaging system before the finished goods are transferred to the warehouse for customer distribution.

Certifications for ISO 9001:2000 and ISO 14001:2004 are done and available.

Manufacturing at the Diemlach plant has a long and varied history. The industrial site itself exists since 1867. Over the years steel, wire and nails have all been produced under different ownerships.

The “Vogel & Noot” Brand arrived on the site in 1985 with the arrival of production equipment for pressed parts (agriculture, automotive) and hot water tanks (150 – 1000 ltr.). In 1996 Vogel & Noot invested heavily and transformed the plant into the production we know today dedicated to special radiators.

With the acquisition of Vogel & Noot Wärmetechnik AG by OY Rettig AB in 2002, Diemlach has been able to flex its capabilities and broaden its sales and distribution base with finished goods now exported to nearly all European countries and beyond.

Certain administrative processes are conducted seamlessly from the nearby Wartberg site in Austria.

Wartberg im Mürztal lies in Styria, a province in mid Austria. Surrounded on all
sides by forest, the town is often referred the "Grüne Mark".

The founding company Vogel & Noot was founded in 1872 along the river "Mürz".
The original business consisted of a forge, a steel refinery and a rolling mill
together with workshops for agricultural tools.

Wartberg has a proud manufacturing tradition. The origin of the manufacture on
this site of hot-water-boilers and the steel-radiators goes back to 1929.
In 1969 Vogel & Noot built itself the first automated radiator production line and the
first powder coated radiator was also produced.
In 1971 a modernized powder coating line came into operation. The origin of the 40mm
pitch with sandwich technique can also be traced to Wartberg.

In 2002 Vogel & Noot Wärmetechnik AG with the locations Wartberg, Mosonmagyarovar,
Walcz, Diemlach and Lilienthal was acquired by the Rettig Heating Group, known today as
Rettig ICC.

At the end of 2006, overcapacity within the steel panel industry together with a
geographic shift in market demand meant that the Wartberg production was no
longer required and the Wartberg plant was finally closed.

Today, Wartberg serves as a distribution and warehouse hub for Austria and
also as the head office for the Rettig Austria GmbH and the Vogel & Noot Brand
Umbrella incorporating the following functions: Management, IT, R&D, Purchase,
Finance, Controlling, Sales and Marketing.
