⚡️Pfannenberg PWS Series⚡️
High‑Efficiency Cooling for Harsh Industrial Environments
In demanding industrial environments, reliable thermal management is essential for protecting sensitive electrical components. Pfannenberg’s PWS Series Air/Water Heat Exchangers offer a highly efficient, low‑maintenance cooling solution designed specifically for applications where traditional air conditioning units struggle — or simply aren’t suitable.
What the PWS Series Does
The PWS Series uses facility-supplied chilled water to remove heat from electrical enclosures. Instead of relying on refrigerant-based cooling, the PWS system transfers heat through a closed-loop air/water circuit, keeping contaminants out and ensuring stable temperatures inside the cabinet.
This makes the PWS Series ideal for environments with:
High ambient temperatures
Heavy washdown requirements
Dust, debris, oil, or airborne contaminants
Outdoor exposure
Food & beverage or chemical processing
Wastewater treatment operations
Anywhere traditional AC units face performance issues, the PWS Series provides a dependable alternative.
PWS 3000 SERIES
Wide range of cooling capacity. Ideal for harsh ambient conditions.
PWS 7000 Series
Pfannenberg’s legacy models. Installation is service friendly requiring no elaborate reworking of the mounting cutout.
Key Features & Benefits
Closed-Loop Cooling The sealed design prevents outside air, moisture, and contaminants from entering the enclosure — protecting electronics and reducing downtime.
High Cooling Capacity PWS units deliver strong thermal performance, with models offering cooling capacities up to 24,000 BTU/h, depending on the configuration.
Energy-Efficient Operation Because the system uses existing chilled water, it eliminates compressor-related energy consumption and reduces overall operating costs.
Minimal Maintenance No filters to clog, no refrigerant to manage, and no compressor to service — significantly lowering maintenance requirements compared to traditional AC units.
Durable, Industrial-Grade Construction Designed for harsh environments, PWS units maintain reliable performance even under extreme conditions.
Flexible Mounting Options Available in multiple sizes and configurations for door or side mounting, making integration simple for both new and retrofit applications.
Where PWS Systems Are Commonly Used
Pfannenberg’s PWS Series is trusted across industries that demand rugged, dependable cooling:
Food & beverage processing
Chemical and pharmaceutical manufacturing
Steel and metal fabrication
Wastewater treatment facilities
Outdoor electrical enclosures
Industrial automation and control cabinets
If your facility already uses chilled water, the PWS Series can provide one of the most efficient and reliable cooling solutions available.
