Our Services
We are a master company in electrical engineering. Electrical systems are the backbone of every building – and their safety is not an option, but a duty. HTM checks, maintains and installs electrical engineering systems and safety systems in accordance with regulations and with the care that this responsibility demands.

With two master electricians in the project management team, HTM possesses the expertise required for complex electrical installations and safety systems. From inspections according to DGUV Regulation 3, emergency and safety lighting, to access control systems, HTM covers the entire spectrum of electrical engineering in the building sector.

Security technology is more than just fulfilling obligations: well-maintained and reliably functioning systems protect your employees, your property, and your business. HTM ensures that this protection is always guaranteed.

Do you have any outstanding questions? We're happy to help.
Here you will find answers to frequently asked questions about our services, maintenance, and technical support. If you have any further questions, our team is always happy to help.
The DGUV Regulation 3 stipulates that electrical installations and equipment in companies must be regularly inspected by a qualified electrician. In principle, all employers are affected – regardless of industry and company size. HTM carries out these inspections professionally and provides complete documentation.
The inspection intervals depend on the type of installation, its location and the environmental conditions. As a guideline, fixed installations are inspected every four years, while movable equipment is inspected more frequently depending on its area of use. HTM will advise you on the intervals applicable to your operation.
During maintenance, our technicians check the function of all lights, batteries, and control components – both in normal operation and in emergency mode. Defective lights or batteries are replaced immediately, and all results are documented.
Access control systems regulate who has access to specific areas of a building and when, using cards, PINs, or biometric recognition. They are particularly useful for companies with sensitive areas, server rooms, or high staff turnover. HTM installs and maintains these systems independently of the manufacturer.
Yes – in addition to inspections and maintenance, we also carry out general electrical installation work in buildings. From new installations to the repair of existing systems – all compliant with regulations and from a single source.
