Thermoelectric Coolers or Thermoelectric Assemblies are designed to remove heat around critical components within an enclosure with IP66 protection category. These is a thermoelectric air conditioner using the Peltier effect. The main advantages of Thermoelectric Coolers over conventional compressor are:
  ·  it can be controlled electronically;
  ·  it is easily reversible when the current is reversed;
  ·  it can work in harsh environments;
  Thermoelectric Assembly NSBon-42 is fundamentally different from standard air-to-air coolers. Based on the calculations, a special design of ambient heat sink was created, which made it possible to remove exterior (external) fans.
  External fans are the weakest link in any air-to-air cooler. They are constantly exposed to extreme ambient conditions and often fail for this reason, after that the cooling process of the internal heat sink stops.
  The NSBon-42 design is 100% protected against sand, dust and water. Even a sandstorm will not disable the NSBon-42 cooler itself and equipment that it cools.
