2 Contents The problem 2-3 Ultra thin resistance heaters 4-7 Guide to our new solutions 8-9 Overview of the offer Unsettled global weather patterns in recent decades have been accompanied by sudden temperature variations, torrential rain, high levels of humidity, extreme temperatures, etc. These phenomena can be harmful to control panels running critical functions (road traffic, infrastructure, continuous processes, etc), which contain a considerable amount of electronic equipment and are often installed in severe environments. Condensation and humidity on Implications... Consequences... Appearance of one of the signs of condensation High humidity Low temperature Dew point frequently reached High costs of service interruptions or breakdowns. Risk of unreliable equipment.

Does your mounting plate make it impossible to install a conventional heater? Do you not want to take out the equipment?

4 Ultra thin resistance heaters: an and condensation Ultra thin resistance heaters have been designed to resolve condensation problems in the most complex installations. Is your enclosure short of space? Does your mounting plate make it impossible to install a conventional heater? Do you not want to take out the equipment? Discover the benefits of this new offer and its numerous mounting solutions. 6Zoom advantages The resistance heaters have been laboratory-tested and have been granted the following certifications: 4 Preventing condensation

5 innovative solution to humidity 1 Minimum thickness They are extremely slim: 1.6 mm. As a result the usable space in the cabinet has been optimised for installing equipment. This can increase the usable space by up to 30%! 2 Heat and safety The heat is distributed over the whole surface and does not exceed 70ºC. This temperature allows devices next to the heater to be handled safely. 3 Multiple options for fixing 4 Numerous positions for installation Innovative quick-fixing system using Velcro pads (no need for a tool!) or with basic fixing accessories (screw + spacer). These systems make it easy to move the heater if necessary. These heaters are so slim and flexible they can be installed in a variety of positions: On the back of floor-standing or wall-mounted enclosure door Vertically on side panels On the mounting plate 5 Low starting current: energy efficiency Ultra thin resistance heaters are ohmic: they therefore have a low starting current. 6 No interference emissions These heaters can be installed near electronic equipment to guarantee optimum heat without the risk of electromagnetic interference.

Traps to avoid Allow a safe distance of 100 mm minimum between the resistance heater and the electronic device. Expert s tip 1 As a general rule, position the hygrostat in the bottom of the enclosure, under the equipment so that the heat generated can benefit all the equipment. Expert s tip 2 Calculate the right choice for your thermal management requirements, according to the environment and the electrical/electronic devices installed in the enclosure. ProClima can be downloaded from our website. Expert s tip 3 The heating speed is chosen according to the control device operating time. For occasional use, choose fast heating. To resolve condensation problems, choose a heater with a slow or average heating speed. 8 Preventing condensation
