PKS Air To Air Heat Exchangers

For the Harshest Environments

Pfannenberg’s PKS 3000 Series Air to Air Heat Exchangers use a revolutionary next generation cooling technology that out-performs conventional heat exchangers and/or heat pipe solutions. One of the best technologies to use when there is a temperature difference between the internal target temperature and the surrounding temperature (∆T≥10°C) is air to air technology.  An air to air heat exchanger removes heat from inside of the enclosure to the cooler environment using the least amount of energy while still providing a closed loop ingress protection.

With five models to choose from, our closed loop PKS Air To Air Heat Exchangers will protect all electronics that don’t require a remote cooling source, and take advantage of our next generation Kinetic Cooling System™ to exchange and remove heat from an electrical enclosures.

Industrial automation is used in almost every area of a commercial bakery, and most electronics utilize a high number of VFDs (variable frequency drives), an extremely expensive and critical piece of machinery.  Technology advancements in VFD drives, which are rated to a min. of 103°F; allow the required ∆T needed for a PKS Air To Air Heat Exchanger to be effective.

DTS Cooling Units

For Harsh Environments

In harsh environments involving high temperatures, wash-down requirements, heavy particles or the presence of chemicals capable of damaging components (NEMA 4 or 12 environments), DTS Cooling Units are the perfect solution to seal out the ambient air, cool and re-circulate clean, cool air throughout the enclosure.

Offered in NEMA Type 4/4X 304 stainless steel, the DTS Cooling Unit utilizes an internal heater which eliminates the need for a drain line, and is coated with special polish to repel contaminants in food applications.

High Temperature models can operate in ambient temperatures up to 140° F (60° C), ideal near baking lines.

Heaters, Thermostats, Hygrostats

For alarming, fan and heater control, primarily in humid areas

Hygrostats switch on electrical enclosure heaters or Filterfans® when a preset relative humidity is exceeded. The relative humidity is kept above the dew point and the condensation of water on electrical components and the corrosion of unprotected sheet metal is prevented, which is extremely important in commercial bakeries where metal particles have been known to make their way into food production.

Heaters are available for cabinets in cold storage areas as well as for condensate management.

Filterfans® & Sanitary Rainhoods

The market-leading solution for extreme environments such as washdown and shipping areas

Our patented Filterfans® incorporate modern louvers which enable maximal airflow, hold back dust/flour and water particles, protect the filter medium from damage and can be integrated into the design of the application.

Filterfans® are an ideal cooling solution in areas of commercial bakeries, such as shipping, where the ambient air is always lower than the temperature required in the electrical enclosure, as they assist the natural convection of the air and help to avoid hot spots within the enclosure.

Though our Filterfan® has been designed for significant weather-related hazards, some environments are simply too extreme for filter fan designs on their own, such as bakery applications, where high pressure washdowns are necessary. In these cases, the addition of a Sanitary Rainhood provides the protection necessary to ensure uninterrupted filter fan and electrical component operation.

The Rainhood’s metal shell provides solid protection against breaking, and provides another barrier against the entrance of water in washdown procedures.
