The updated 34X1C / DTS 36X1C Series Cooling Units offer superior capacity, a more efficient design, and a robust build compared to previous models to ensure a longer service life. The DTS 34X1C units provide 1.5 tons of cooling capacity and the DTS 36X1C units provide up to 2 tons  at normal operation. Both series are designed with the same dimension and mounting cutout, so they can be easily interchanged depending on cooling demand. They are also backwards compatible with Pfannenberg’s older designs (DTS 34X1 and DTS 36X1), making them a versatile option for enclosures cooling. The electrical system of these cooling units has been updated to include a smaller and simpler power connecter to reduce the protrusion of the connecter into the cabinet and free up valuable real estate.

Other features include easy panel access and a front status LED display to help simplified maintenance or service intervals. These cooling units were built on an open design, so critical components can be accessed easily for maintenance purposes. The refrigeration system is totally redesigned with longer and more robust service life in mind helping end users focus on uptime and prevent disruption in operation. Both of these units are ideal for high heat loads, especially high horsepower drive enclosures. They are available in different NEMA or UL Type ratings  (12/3R/4/4X) and different voltages. They also include many other critical-to-application features, such as active condensate management, coated corrosion-resistance condenser coils, and high flow evaporator fans. Options for low ambient, integrated heater, and Modbus connectivity will be available soon.
