Utilize closed loop cooling in tough industrial or outdoor applications with Pfannenberg’s ‘service-friendly’ cooling units. Whether in washdown locations or control rooms, the DTS Series’ key internal electronics are positioned away from potentially moist and/or caustic air in tough industrial applications. The wide condenser fin spacing allows for filterless and maintenance-free operation. The stainless steel units have an epoxy coating on all exposed copper tubing to compliment the electrostatically-coated condensers. The fans are conformal coated, backward curve impellers that have a standard life of 55,000+ hours, providing the longest life and best air flow in their class.
