Pfannenberg USA has released the ActiveCool DTS 5000 Series of enclosure cooling units. These units, which are rated to UL 60335 standards, provide cooling for narrow 12-inch-wide cabinets.
Why it matters
The DTS 5000 series is designed to protect sensitive electronics in dense control cabinets while helping facilities comply with environmental regulations. This launch addresses the increasing heat density in modern industrial hardware deployments.
The DTS 5000 Series supports cabinets as narrow as 12 inches and utilizes A1 nonflammable R513A refrigerant to meet safety standards. The units deliver cooling capacities of 4,700 and 8,500 BTU/hr with Type 12, 3R, and 4X protection ratings.
The players
Pfannenberg USA
A division of the global thermal management manufacturer providing cooling solutions for industrial and data center environments.
The details
The cooling system functions by drawing hot air from the top of the enclosure and delivering cooled air into the bottom of the cabinet. Maintenance is streamlined through external access, which allows technicians to service the unit without opening energized electrical cabinets. This design minimizes the risk of exposure to live components while maintaining required environmental protection ratings.
Timeline
September 28, 2026: Pfannenberg USA launched the DTS 5000 Series.
The Tech Race
The DTS 5000 Series aligns with the broader industry effort to reconcile increasing power density in small-form-factor enclosures with strict environmental compliance. This release follows a pattern set by California's environmental regulations for industrial hardware regarding heat management standards.
Facility managers can now integrate cooling into 12-inch-wide configurations that previously faced thermal constraints. These units prioritize technician safety by allowing maintenance tasks to be completed without opening the primary enclosure doors.
The takeaway
The move toward compact, high-density cabinet design requires more efficient cooling that meets rigorous UL 60335 safety benchmarks. Engineers should monitor the upcoming hardware certification updates to verify these units against site-specific heat load requirements.
