Pfannenberg PKS 3000 Series

PKS Air/Air Heat Exchangers Traditionally if the ambient air was cool enough but too contaminated to use for Filterfan® cooling the next option selected was an industrial air conditioner. This solution led to oversizing and energy inefficiency. Pfannenberg introduces a revolutionary new technology that fills the gap between Filterfans® cooling units, using the cooler ambient air that is already available. • Reduce monthly operating expenses • Reduce maintenance costs • Reduce energy costs • Reduce heat released to the surrounding area When Should You Use a PKS Air to Air Heat Exchanger? » If the ambient temperature is lower than the temperature required in the electrical enclosure. » If a separate closed loop internal and external air circulation system must be created for cooling due to the ambient air being too dirty to be brought into the cabinet for cooling. PKS Air/Air Heat Exchangers Understanding Other Types of Cooling When Should You Use a DTS Cooling Unit (A/C)? » If the ambient temperature is equal to or higher than the temperature required in the electrical enclosure. » If a separate closed loop internal and external air circulation system must be created for cooling due to the ambient air being too hot or dirty to be brought into the cabinet for cooling. When Should You Use a Filterfan® ? » If the ambient temperature is lower than the temperature required in the electrical enclosure. » If open loop cooling is acceptable because the external air is clean enough to be filtered into the cabinet air for cooling. Filterfan 4.0TM DTS Series Enclosure Cooling Units and enclosure When Should You Use an PWS Air to Water Heat Exchanger? » If the ambient temperature is equal to or higher than the temperature required in the electrical enclosure. » If the external ambient air is too contaminated to be used as a separate external circulation system to discharge the heat. Water from a chiller or other chilled liquid source is used in place of the external air for the secondary circulation system.
