When electrical components are exposed to contaminants such as dirt, dust, humidity, or corrosive vapors, they can become damaged and eventually fail. Selecting a cooling solution that protects the components inside an enclosure from outside contaminants can save you money on expensive equipment repairs, employee downtime, and equipment replacement.
Although industrial electronic components are generally robust and well designed, they are sensitive to contamination, moisture, and excessive temperature. They need to be kept cool, dry, and free of dust, debris, and corrosive chemicals. These requirements are to a certain extent in conflict because good ventilation is generally required for cooling, but protection from dirt and contamination requires a sealed enclosure.

An enclosure cooling system is necessary to remove the heat dissipated by the electrical equipment and to keep the temperature of the enclosure regulated. While filtered fans can remove some of the heat through forced convection, in most other cases, a closed loop cooling system is essential for optimal regulation of temperature without exposing the electrical equipment to ambient air. Typically, air-to-air heat exchangers and closed loop air conditioners take advantage of this principle to cool the enclosure. Continue reading →
Electrical components, such as variable frequency drives, PLCs, contactors, and switches, as well as the equipment and machinery they control, represent a large upfront investment in almost any industry. Failure of these components due to excessive temperatures may even cause a chain reaction, leading to inefficient operation, damage or failure of the machinery in the factory or mill.
Wastewater treatment facilities present unique hazards to electrical enclosures. Extremely harsh conditions commonly present during wastewater treatment include highly corrosive liquids, gases and vapors such as chlorine, hydrogen peroxide, and ammonia. Some enclosures may also encounter salt spray and possibly even flammable gases generated by the decomposition of waste.
Selecting a new enclosure cooling solution or upgrading to another product can be challenging. This is especially true when looking for both a new enclosure cooling system and a reliable manufacturer of high quality products who provides excellent customer service and technical support.
Enclosure heat exchangers are excellent cooling system solutions for many industrial applications. Because they use ambient air and require very little electricity, they are one of the most energy efficient systems available. Using a closed loop heat exchanger system also has the advantage of keeping outside dirt and other contaminants away from sensitive electronics.
When electrical systems produce excess heat in an enclosure, a cooling solution is required to ensure that there is no damage to sensitive components. In some cases, a filtered fan that blows air through the system is sufficient. But what happens when the outside air has contaminants like dust and dirt or oil? The filtered fan may provide the cooling you need, but it will deposit these contaminants on electrical components at the same time.
When excess heat is generated in electrical enclosures, it must be transferred outside the enclosure to help protect the sensitive components inside. Temperatures inside an electrical enclosure that exceed the maximum operating temperatures of the components inside can result in equipment damage or even failure.
