Why Cabinet Coolers Are Better Than Heat Pipes and Air Conditioners
An industrial cabinet cooler is a way to provide air conditioning to electrical enclosures and purge or cool electronic control panels. They eliminate electronic control downtime caused by dirt, heat and moisture. This is the opposite of other cooling options, such as heat pipes and air conditioners. When weighed against cabinet coolers, air conditioners and heat pipes are considered unreliable. Below are reasons why cabinet coolers are more reliable than heat pipes and air conditioners.
The Problem with Heat Pipes
Heat pipes have many limitations. For example, on hot days the temperature of a room can become almost equal to the temperature of an electrical enclosure, which can prevent heat exchange from occurring. This happens because when rooms and enclosures are nearly the same temperature there isn't enough difference for heat exchange to occur. So, the cooling capacity is limited by ambient conditions. Heat pipes may also fail if dirt and dust clog the filter.
The Problem with Air Conditioners
Air conditioners have many limitations in industrial surroundings. They are notorious for failing due to dirt and dust clogging the filter. Vibrations from machinery can cause component failures and refrigerant leaks. They require a floor drain because of condensation. Their compressor life is only 2.5 years of continuous operation, and thermostat control can reduce this life even more. Plus, replacing a bad compressor can cost as much as $750. Besides that, they take nearly a day to install, meaning a machine will be halted for that day.
Industrial Cabinet Coolers vs. Heat Pipes vs. Air conditioners
Industrial cabinet coolers stack up well again air conditioners and heat pipes. They use a vortex tube to produce cold air from compressed air, so they have no moving parts. The parts of air conditioners and heat pipes often fail due to clogged filters and mechanical wear. Because cabinet coolers have no moving parts that wear out, they are maintenance free, thus more cost effective than the other cooling options.
Cabinet coolers can be installed within minutes while air conditioners and heat pipes can take hours or even an entire day to install. Coolers also keep panels constantly dry and cool at an average temperature of -6° C while air conditioners have condensation that keep panels moist, and heat pipes are prone to temperature fluctuations and overheating. Overheating of electronics can lead to heat damage to circuit boards and shut downs due to tripped breakers and overloads. However, because industrial coolers maintain a constant temperature machine shut downs, trip-outs and erroneous readings never occur. Visit Pelmar Engineering if you would like to learn more.
