Pfannenberg Combines Free and Active Cooling in DHS Hybrid Series
Maximize Cooling While Minimizing Energy Use and Reducing Carbon Emissions
Lancaster, NY - Pfannenberg, Inc., a leading global manufacturer of thermal management and signaling technologies, proudly announces the DHS Hybrid Series (DHS 34X1). By combining free cooling with active cooling, this closed-loop system safeguards critical electronics within an enclosure while lowering energy consumption, cutting costs, and reducing carbon emissions.
The DHS-Series achieves its optimal efficiency by combining free cooling with active cooling. Free cooling is a technology that minimizes energy use by using the cooler air outside the enclosure to remove heat from inside the enclosure. Active cooling utilizes a compressor and refrigerant cycle to cool the air in the enclosure when it exceeds the desired temperature of the enclosure. This combination optimizes the efficiency of the cooling unit thereby reducing energy usage. This dual system also provides redundancy in a single unit to avoid downtime, fits all full-sized enclosures, and also features an easy to read status display.
The DHS-Series is offered in indoors (Type 12), outdoors (Type 3R/4), and in washdown (Type 4X) configuration. The product proves ideal for locations with lower ambient temperatures, climate controlled facilities, and operations that periodically run at partial capacity. This can include everything from automotive manufacturing and warehouse automation to outdoor facilities and food and beverage manufacturing.
The DHS-Series meets high standards for electrical safety, being certified to the UL 60335 standard. Additionally, the hybrid cooler is pre-gasketed to make installation even easier. The product has also been designed to meet upcoming environmental regulations governing the use of the R-513A refrigerant.

T.J. Davies' Retention Knobs
Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
