Pfannenberg, a specialist in thermal management and signalling technologies, has introduced its new ActiveCool DTS 5000 Series of enclosure cooling units, designed for reliable performance, simplified installation, and safer, more efficient service in a range of industrial applications
Expanding on a proven design, the DTS 5000 Series adds key enhancements in refrigerant technology, airflow, and user interface to better protect critical electronics in densely packed control cabinets.
The DTS 5000 Series uses a long internal air path that draws hot air from above heat-generating components and delivers cooled air below, maintaining uniform enclosure temperatures. A large evaporator coil supports higher airflow for high-density electrical enclosures, while a compact, side-mount design fits most 12-inch-wide cabinets. Each unit comes standard with R513A refrigerant, helping customers meet environmental regulations, including those affecting California and IT applications, and is rated A1 nonflammable for added safety.
The series provides models in optimised cooling capacities of 4,700 and 8,500 BTU/hr to cover a range of heat loads, with Type 12, 3R, and 4X protection for dusty plant floors, washdown, and outdoor infrastructure.
Critical components can be accessed from outside the enclosure, enabling maintenance without opening an energised cabinet and avoiding lockout/tagout procedures while reducing downtime. A preinstalled enclosure gasket also reduces installation time.
The user interface is streamlined through external status and display options. Customers can choose an LED status indicator version for quick visual confirmation that the unit is running, or a digital display controller version that lets them view and adjust temperature settings from outside the panel. The series is listed to UL 60335, reflecting improved safety standards for modern industrial equipment.
James Wong, director of Product Management, said, “By combining an environmentally friendlier R513A refrigerant with full external service access and advanced airflow design, we are giving panel builders and end users a smarter way to manage heat in today’s demanding industrial environments.”
