In 1989 Helmut Siekerkotte founded the company in Hiddenhausen, Germany. Initial production started in a small, rented factory hall.

In 1996 the company decided to rent another hall to be able to expand its production capacities.

The conversion to a limited company took place in 1992. However, Mr. Helmut Siekerkotte remained Managing Director and sole shareholder.

In 1997 the company started developing, designing, manufacturing and selling electric stainless steel air heaters, electric warming cabinets and barrel heaters.

With over 20 employees Siekerkotte GmbH is a flexible company with the company’s structures deliberately maintained on an informal level. Terms such as team spirit, cost consciousness, cooperation as partners are not only goals to be achieved but every day reality.

As a manufacturer of electric heater elements we address our customers from the automotive supplying, air conditioning technology, ventilation technology, mechanical engineering, regenerative exhaust technology and high-temperature technology sectors.

We offer complete solutions for electric air heater and electric flange heater engineering.

In addition the company is focussed on manufacturing electric warming cabinets and barrel heaters.

A quality management system in compliance with DIN EN ISO 9001:2000 has been applied at Siekerkotte GmbH since 1998. Proof of compliances has been given within the certification audit report no.
