Production

No Compromises with a Vertical Manufacturing Range

Technically optimum performances do not happen by chance at HTT; they are an intrinsic part of our programme. Tradition, experience and constant optimisation are the key to this success, as well as the uncompromising dedication to the exclusive in-house manufacturing of all our components. This is due to the fact that we maintain the optimum control over manufacturing standards within our own enterprise at our locations in Herford (4,000 m²) and in the Spreewald (5,000 m²). The manufacturing depth at HTT is unique in the branch:
 

• Electronics ad MSR departments dedicated to the planning and manufacture of monitoring, controlling and regulation devices, as well as substations.
• Mechanical manufacturing: Turning, milling, drilling, pipe and sheet steel bending and TÜV/DIN safety standards authority approved welding techniques
