HEATING - semiconductor heaters

When the temperature gets too low inside control cabinets, enclosures and technical installation spaces, this can lead to the formation of harmful condensation. Here's how you can achieve the perfect control cabinet climatisation at subnormal temperatures and critical humidity levels: use our PTC heaters and resistance heaters to heat your control cabinet. Enclosure heaters with a fan also strengthen the convection effect and distribute the warmed interior air more quickly.

Enclosure heating semiconductor for alternating or direct current applications:

  • with or without ventilation or temperature control;
  • mounting on the DIN rail or directly on the counter panel;
  • in the protective case;
  • with powers between 10W and 1200W.

COOLING - fans, filter fans

Optimal control cabinet cooling is an investment in long-term success. Prevent excessive temperatures, which can occur in tightly fitted control cabinets and may lead to malfunctioning of electrical and electronic components. Our filter fans and fans for control cabinets reliably prevent overheating and damage to components.

Fans for alternating or direct current applications:

  • various sizes;
  • circulated air volume from 23 mc/h to 1031 mc/h;
  • mounting on the front of the panel or on top of the ceiling;
  • with / without flaps;
  • with degree of protection up to IP56.

REGULATING - thermostats, higrostats, thermo-hygrostats

Ensure perfect climatic conditions in control cabinets and enclosures using our temperature and humidity control systems: our temperature controllers and hygrostats control and regulate connected heaters or filter fans with both AC- and DC-powered applications, thereby enabling the perfect feel-good climate for your electronics.

MEASURING - sensors for condition monitoring

Condition monitoring is an essential part of planning the maintenance of plants and machinery. This does not only apply to control cabinets and enclosures in industrial systems, but also to a wide variety of applications in which controlled processes take place.

Condition monitoring is a method of mitigating an emerging problem as early as possible, before it actually turns into a serious fault or even an outage. It is based on constant or regular recording of physical data. Devices such as smart sensors record parameters such as temperature and humidity and convert this data into analogue or digital signals. Our range does, of course, also include solutions for IO-Link systems.
