Heating cabinets - Import export

Electrical and electronic equipment mounted inside a cabinet generate heat that raises the temperature internal air. Over time, the ever increasing heat can cause sensitive devices to malfunctions. Additionally, heat accumulation can cause circuit breakers to trip which can result in system shut down. Fan filter units are used for enclosure climate control to dissipate heat from within the enclosure to prevent the premature failure of the equipment inside it. It helps to increase an operational reliability and a service life for electrical and electronic systems. Filter fans will cool enclosures to a level slightly above the ambient temperature outside the cabinet. To cool enclosure contents, the fans draw filtered ambient air into the cabinet. At the same time, the heated air within the cabinet is blown out an exhaust. The exhaust is also filtered which creates airflow resistance and a slightly higher pressure inside the enclosure.

Electronic equipment installed inside a cabinet emits heat, which raises the internal temperature. Over time, rising temperature can cause electronic devices to a fail. Thermoelectric Coolers or Thermoelectric Assemblies are designed to divert an excess heat from electronic equipment installed inside an electrical enclosure. NSBox-ICE is a special series of electrical enclosures with installed thermoelectric assembly. The units are mounted in various series of electrical enclosures with protection category IP66 / NEMA4: powder-coated sheet metal, glass reinforced polyester, depending on the field of application and operating conditions. The basic kit includes the selected assembly with a thermostat, a mounting plate with DIN rails for customer equipment, terminal blocks, a circuit breaker, an electrical grounding bar, the set of selected cable glands. The cable glands are mounted in the bottom of the enclosure, e.g. on a removable metal plate for sheet metal cabinet.
