Recent work done at a City of Los Angeles Water Treatment Plant required the improvement of a large odor control system. For the odor control system to work properly, 200HP fans are needed and to meet the cooling needs of the system, the City of Los Angeles considered a variety of Thermal Management options.
Pfannenberg’s DTS 3681 (NEMA Type 4/4x) Side Mounting Cooling Units were selected for the job. The stainless-steel cooling units have a large capacity, at almost two tons. They are specially designed for long term use in high temperature, high ambient environments, such as the odor control system.
The DTS 3681 cooling units are self-protecting from harsh environments due to a number of features, including the location of the control electronics within a dry, cool interior circuit. All the constituent components comply with the highest standards which makes these cooling units, the best option for protecting critical electronics.
Pfannenberg DTS Cooling Units closed loop design isolates the external ambient air from the internally conditioned air eliminating the risk of contaminants entering the cabinet. The hermetically sealed compressor guarantees 100% cooling capacity efficiency. The absence of any refrigerant fill valves eliminates leak paths.
Pfannenberg’s DTS 3681 Cooling Units are sure to last long in serving the odor control system. Reasons for this include the high airflow backward curve impeller fan, which provides high airflow in a long lasting, single bearing design. This is in contrast to the typical two-bearing blowers, with the DTS 3681 Cooling units boasting nearly twice the lifespan!
