05.06.1961 Leo Möskes established a rm in sole proprietorship for the manufacture of wastewater treatment systems in Röthenbach near Nuremberg / Germany. In control cabinets that were operated around dew point terperatures, at that time, light bulbs were installed to avoid falling below dew point temperature by means of the light bulb's waste heat. 01.10.2002 The Achter Elektronik AG aquires the partner's interest share of Lm-therm Gmbh. 12.08.1993 Foundation of the rm in sole proprietorship: Franz Achter Elektrohandel & Systemtechnik Achter Elektronik AG and Lm-therm GmbH utilize the...

To what should attention be paid in control cabinet climatization? Required heating capacity (values based on experience) A. Heaters with integrated thermostat For industrial applications C. Ventilator / blower heaters Customer-specific heater solutions/mounting, Product ranges: - the safe heater solution for any application -

Why is heating respectively cooling necessary inside control cabinets? Meanwhile - as it is known, also the subject "control cabinet cooling" has become fairly important in addition to control cabinet heating. • Control cabinet climatization: heating and / or cooling! • Temperature/humidity or also temperature and humidity! Multifarious fields of application show that this issue is not only prevailing in the control cabinet: automation, traffic and automotive engineering, telecommunication, switchboard and control pa- nel systems, distributor control cabinet systems, read-out displays in...

Required heating capacity (values based on experience) To successfully prevent formation of condensation water, the temperature inside an enclosure must not drop below dew point temperature.

General details on control cabinet climatization A uniform heat distribution is obtained by installing the heater in the lower third of the control cabinet ^ - cooling units however should be installed in the upper area. $ It should be attempted not to influence the natural convection of heating by an extreme packing den- sity of built-in components installed. By installation of air circulation fans respectively ventilator hea- ters, effectiveness and heat distribution can be optimized! Cooling units are equipped with ventilators 3) Surface temperatures at PTC heaters Because of high...

The appropriate solution for your A. Heaters with integrated thermostat (catalogue pages 13-21 Our heaters consist of ceramic heating elements integrated into an aluminum casing designed to thermal specifications with built-in 2-position bi- metal temperature controller. The resistors and power curves of this heating system show linear 1) The built-in temperature controller provides for operational safety. 2) Because of the built-in temperature controller, high surface temperatures that might influence the built-in components in their functional relia- bility or damage them do no occur. 3)...
