A conditioned enclosure absorb or dissipate heat through its walls according to its material, dimensions and the difference between internal enclosures and ambient temperature (t). This value is determinate by a simple calculation
2(m x t x5)W, (as assuming the enclosure made in steel, transfer coefficient = 5), see the selection chart below for a quick reference:
First question to ask in order to select the appropriate cooling equipment is: “Can the internal enclosure temperature be higher than the external ambient temperature ?
, we will choose between an air conditioner and a water to air heat exchanger. In this case, the heat absorbed by the enclosure, at specified limit conditions, has to be added to the heat dissipated by the internal components. Using an air conditioner can be maintained constant the internal enclosure temperature, independently from the variation of outside ambient temperature. If an air conditioner is used, it is suggested to keep the internal temperature to a minimum of 30°C to avoid condensate water production when an operator will open the enclosure door. Temperatures lower than 30°C may cause the installed components to be covered of condensate water when warmer external air enter in the enclosure.
, we will choose an air to air heat exchanger or a forced ventilation system, that uses filtered primary air. In this case the heat absorbed by the enclosure, at specified limit conditions, has to be removed from the heat dissipated by the installed components. Air to air heat exchanger cooling capacity is measured in W/K, this value indicates how many Watt the heat exchanger can remove for every degree of temperature difference between internal enclosure temperature and external ambient temperature. For example, a 30 W/K cooling capacity heat exchanger can remove 450W of heat, if ambient temperature is 35°C and internal enclosure temperature is 50°C (i.e. 50-35 = 15 difference of temperature x 30 = 450W).Only as an indication, heat dissipation by components can be calculated using the below table:
transformers drivers, PLC, numerical controls , inverters suppliers moving-coils relay, contactors incandescent lamps heaters

he KSL “slim line” air-conditioners are designed to be installed vertically inside and outside the control board. This new product line represents the latest technical innovation from Kelvin's research and development department. All parts are accessible by simply removing the front panel, so Teliminating the need to remove the unit from the control board. This model can be used with or without an air filter. The condensate is collected and
then dissipated into the external ambient. This unit can be installed outdoors without worrying about associated air pollutants.

KSAhe KSAs 18-19 are air-air heat exchangers, which are particularly suitable for side or door installations on small control boards and other small enclosures which require minimal cooling within limited room conditions. These two models use four axial fans, which provide improved air Tcirculation and temperature distribution. The external circuit fans can be controlled by a DIN bar thermostat, saving energy and reducing noise.
The control board circuit fans have to run permanently to avoid heat-pockets from forming. Four M6 threaded inserts are provided for fixing onto the cabinet.

There are two types available: the wall mounted version and the mini-tower for roof mount installations on control boards. They have a particularly high air flow rate. Ventilation Twith filtration represents an efficient solution in those cases in which the working ambient air is clean and the temperature inside the cabinet can
be higher than the external one. KELVIN offers with the KEA product line a solution panoramic suitable to satisfy any applicative, aesthetic and technical need. The new and exclusive KEA200 has a wide filtering area. This highly efficient design practically eliminates the need to clean the filters and represents a perfect example of KELVIN's continual commitment to developing new and innovative designs for the future.

nti-condensate heaters are indispensable to avoid condensate from forming inside the cabinet during a unit's standstill and in instances of very low ambient temperatures or very high humidity. Since hot air tends to rise they have to be positioned in the lower part and possibly beneath Athose components that require protection. Maximum efficiency is reached installing the heater in a vertical position and orientating the supply
cable downwards. In case of large cabinets it is advisable to use multiple low rate heaters to obtain an unvarying temperature distribution. All KELVIN heaters are provided with a snapping fitment for the DIN EN 5002 conform 35 mm bar.
