STEGO has decades of experience in the field of climatisation of enclosures and control panels, traffic control and monitoring systems in the transport industry and rail signalling techniques. With its range of products it offers user-friendly solutions and provides a high degree of safety for the operation of your facilities without interferences.
Innovation and design are central to STEGO’s product development philosophy. The company’s own product development department and design office develop and construct its products. STEGO products are renowned for their reliability, long life, simplicity of use and high quality.
With locations in 11 countries and long-time business partners, STEGO is represented worldwide. STEGO products are exported internationally and used in a variety of different areas and climate conditions.
STEGO’s products include conventional and PTC semiconductor control panel heaters and fan-assisted heaters (from 5W to 1,200W) as well as Ex variations. Temperature and humidity controls range from 0°C to 60°C (32°F to 140°F) and 35% to 100% RH. The filter fan series in EMC and standard versions have excellent performance and shielding characteristics and it also offers panel lighting and accessories.
Convection heaters for railways
Fluctuating temperatures means condensation can form in enclosures, which can lead to serious malfunctions or, in the worst case scenario, a component failure. Convection heaters protect against low temperatures, thus preventing the formation of condensation. Furthermore fan heaters provide forced air circulation and ensure constant temperatures in enclosures.
STEGO’s CS heating product range is ideal for railway enclosures where space is crucial as it offers a small compact design, a low surface temperature, a quick mounting due to clip fixing and a wide voltage range. The heaters are quiet in operation and are vibration resistant. Models with plug-in thermostats that do not require additional wiring are also available. The casing is plastic according to UL94 V-0.
Filter fans for overheating control
High component densities in enclosures generate increased temperatures which can cause component failure. Filter fans protect against overheating in the enclosure, preventing malfunctions of electrical and electronic components by diverting the warm air away from heat sensitive components.
STEGO’s filter fan series offers a range of advantages for the railway industry, for example, the self-adhesive seal of the mounting frame to prevent dust and water from entering the cabinet and the design effectively prevents direct intrusion of falling water and dust. Its fans are quiet in operation and enable time-saving assembly, they are weatherproof and UV resistant. STEGO’s unique outdoor filter-fan is also lockable.
Temperature and moisture control for heaters, filter fans and heat exchangers
A prerequisite for a clean operation of signalling equipment is the right climate in the enclosure. This can be attained by a temperature and moisture control system which is put in place. Thermostats and hygrostats are used for the control of heaters, filter fans, heat exchangers and air conditioning equipment. They activate when set temperature or humidity values are exceeded or have fall below a specific temperature.
A thumbwheel setting dial, small hysteresis, high switching capacity and a sensitive bimetal are the main highlights of our thermostat STO/STS. The optimised housing provides a better air flow. The setting wheel has an anti-frost assurance. Thermostats are also available as dual devices.
