Keep Contaminants Out – How Air to Air Heat Exchangers Protect Your Electrical Enclosure

 

air-to-air-heat-exchangers-keep-contaminates-outWhen 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.

Cooling Options for a Sealed Electrical Enclosure

 

cooling-options-for-a-sealed-electrical-enclosure

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.

How a Closed Loop Cooling System Can Cut Costs

 

How_a_Closed_Loop_Cooling_System_Can_Cut_Costs

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

6 Ways Active Enclosure Cooling Will Protect Your Investment

 

6_Ways_Active_Enclosure_Cooling_Will_Protect_Your_Investment.jpg

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.

Here are six ways a “closed-loop” active enclosure cooling system, will protect your equipment investment: Continue reading

Closed Loop Cooling Systems in Wastewater Treatment: 3 Big Mistakes

Closed_Loop_Cooling_Systems_in_Wastewater_Treatment-_3_Big_Mistakes.jpg
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.

Preventative Maintenance for Electrical Enclosure Heat Exchangers

 

Enclosure-air-to-air-heat-exchanger-maintenanceEnclosure 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.

Protecting Electrical Enclosures with Closed-Loop Cooling Systems

 

closed-loop-cooling-electrical-enclosuresWhen 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.

Understanding Heat Transfer in Electrical Enclosures

 

heat-transfer-for-electrical-enclosuresWhen 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.
