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/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.
Utilizes lower temperature ambient air to cool warmer internal air without a compressor
The simple design of the PKS means that only the fan will ever have to be replaced
The compact, lightweight design means that the unit can be installed by just one person
To better understand the advantages of the PKS 3000 Air/Air Heat Exchangers let’s take a look at how it compares to a traditional cooling unit. AC/Cooling Units are typically the go-to solution for cooling an enclosure. What many people fail to consider is that a cooler ambient environment could be used to help cool your warmer electrical enclosure. This new air to air technology takes advantage of a cooler ambient environment especially in harsh (dusty, oily, dirty) conditions when closed-loop cooling is required. Here we demonstrate the considerable saving you could see with this new technology compared to an AC unit.
The PKS 3000 Series Air/Air Heat Exchangers are available in 5 different models. The cooling capacity ranges from 22 Watts/°C to 180 Watts/°C. If you need assistance choosing the right model don’t hesitate to ask us or use ourPfannenberg Sizing Software. This is a perfect solution when concerned with the open loop Filterfan® designs that don’t prevent corrosive gas or humidity from entering the enclosure. We’ve designed these units to be versatile for indoor cooling, outdoor or remote applications that require a closed loop system to protect electronics. Available in 5 models; PKS 313X, PKS 320X, PKS 330X, PKS 336X
The PKS Mini series Air/Air Heat Exchangers are ideal for the replacement of a Filterfan® solution when the ambient air is too contaminated to enter the cabinet. Available in 2 models; PKS 3042, PKS 3092
Cooling Capacity Per Density
Heat removal capability compared to the physical size (volume) of the cooling unit. A higher ratio indicates higher cooling power per volumetric size.
CCPD™ = Cooling Capacity (BTU/HR) / Volumetric Size (IN3)
Produces superior Cooling Capacity Per Density vs. conventional heat exchanger and/or heat pipe solutions. One of the most compact units for the available cooling capacity.
Utilizes lower temperature ambient air to cool warmer internal air without an active component such as a compressor which consumes high amounts of energy.
The width of the unit is maintained at 12 inches to fit onto the side of a smaller NEMA enclosure.
With only two mechanical components (fans), potential failure point is reduced to ensure continuous uptime of your processes.
The Unit can be installed vertically or horizontally, allowing the cool air to be focused where it is needed the most.
Designed to isolate external ambient air from internal air eliminating the risk of contaminants entering the cabinet. Compared to Filterfans® with Rainhoods; the PKS seals against gaseous substances, humidity and airborne particulates such as dust, keeping it away from sensitive components within the electrical enclosure.
Compact lightweight design means that the unit can be installed by just one person
Uniquely designed to operate in NEMA 3R, 4, and 4X environments. An example of this is the location of our control electronics within our dry, cool interior circuit.
