Why is a Thermal Management Plan for Enclosures Important?
Thermal Management Plan for Electrical Enclosures M
anufacturing facilities’ electrical enclosures can house hundreds of thousands of pounds in high-performance drives and electronics critical to production processes. These critical electrical of heat which, if not managed properly, leads to premature product aging and failure, shutting down systems and resulting in unnecessary downtime. application is critical. Considerations for thermal management include heat load, ambient temperature range, presence of particulates or debris, enclosure location, material and more. Unfortunately, most manufacturing facilities lack a proper Thermal Management Plan to protect and extend the life of their equipment. As a result, losses each year. In most cases, these losses are preventable with a well-designed Thermal Management Plan.
Pfannenberg Can Help Develop a Thermal Management Plan
A good thermal management plan starts with a plant survey to evaluate the needs service and support team offers several programs to determine if the correct cooling technology is in place and functioning properly to meet the needs of that particular facility. A thermal management program from Pfannenberg can help: • Verify sizing of cooling method meets the thermal loads of enclosures
• Reduce electrical costs caused by poorly maintained air conditioners
• Create a preventive maintenance plan • Recommend the correct thermal technology for challenging applications
• Identify critical equipment and put steps in place to reduce downtime
• Pfannenberg offers a variety of thermal management products tailored to meet the needs of different manufacturing environments.
Air to Air Heat Exchangers Pfannenberg’s PKS 3000 Series Air/Air Heat Exchangers use its kinetic cooling system to exchange and remove heat from electrical enclosures using ambient air. This is a solution for applications with humid ambient temperatures or dirty air where reductions in maintenance are critical. Available in indoor, outdoor and remote applications, as well as washdown applications that require a closed-loop system to protect electronics.
Air to Water Heat Exchangers Pfannenberg Air/Water Heat Exchangers are particularly suitable where ambient temperatures are high or for washdown areas of the plant with high amounts of particulate. Their maintenance-free design installation, whether internally or externally. a supplied water source to remove heat, which is the most effective method for process heat removal. With high cooling capacities ranging from 2,218 BTU to 34,121 BTU, they are engineered to ensure safe and making them an ideal choice for a variety of industrial applications.
Cooling Units
Pfannenberg Cooling Units offer a closed-loop cooling system to prevent overheating. The units effectively seal out ambient air, ensuring that clean, cool air is recirculated throughout the enclosure. These units can be used when the required internal temperature is equal to or lower than the ambient temperature or when the ambient air is heavily contaminated with oil or conductive dust and higher ingress protection is necessary.
Filterfans
For less demanding environments, Filterfans offer a cost-effective solution to manage enclosure temperatures. With tool-free that guarantees Nema Type 12 protection ideal solution for clean, non-hazardous environments as long as the ambient temperature outside the enclosure is lower than the enclosure temperature.
