1. Filterfans®
(back to index)▲
Otto Pfannenberg's invention of the Filterfan® in 1958 was a milestone in the area of industrial thermal management.
As a result of over 50 years of experience and continuous development, Pfannenberg's Filterfans® have evolved into the trusted name for forced convective cooling to circulate and cool the air in your cabinets.
If the ambient temperature is always lower than the temperature required in the electrical enclosure, then Filterfans® represent an economical solution for thermal management of electrical enclosures.
Filterfans® are the ideal solution for clean, non-hazardous environments with an acceptable ambient (outside the enclosure) temperature range. When the amount of heat being removed from your enclosure is minimal, the use of PFA Exhaust Filters can be effective.

Pfannenberg's
DTS side-mounting series cooling units are driven to meet the demands of our North American NEMA market. These units meet
the needs of indoor NEMA Type 12 applications, NEMA Type 3R/4 outdoor applications and NEMA Type 4/4x stainless steel for washdown
applications. Revolutionary designed
DTT top-mounting series cooling units offer unique protection through Pfannenberg's innovative, patented condensate management
system. These units can be safely installed above critical components with peace of mind. The
DTI recessed-mounting series cooling units allow for European style recessed mounting on enclosure doors and/or side panels on
modular systems. These "click & fit" units reduce installation times by more than 90%.

3. Heat exchangers
(back to index)▲
The PKS series air / air heat exchangers use Pfannenberg's Kinetic System™ next generation cooling to exchange and move the heat from an electrical enclosure to the outside environment. 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. Designed for indoor cooling, outdoor or remote applications that require a closed-loop system to protect electronics.
The PKS series features an energy efficient, minimal maintenance and reduced footprint design that is a proven solution in harsh environments. These units offer a closed loop design to isolate external air from inside of the enclosure without the need to change the filter.

Features:
- Best CCPD: produces superior cooling capacity per density vs. conventional heat exchanger and/or heat pipe solutions
- Energy efficient: utilizes lower temperature ambient air to cool warmer internal air without an active component such as a compressor which consumes high energy
- Narrow width: width of the units are maintained at 12 inches to fit onto the side of any smaller NEMA enclosures
- Reduced maintenance: with only two mechanical components, potential failure point is reduced to ensure continuous uptime of your process
- Flexible mounting options: a unit can be installed vertically or horizontally, allowing the cool air to be focused where it is needed most
- Closed loop design: designed to isolate external ambient air from internal air eliminating the risk of contaminates entering the cabinet
- Easy installation: compact lightweight design means that the unit can be installed by just one person
- Self-protected from harsh environments: uniquely designed to operate in NEMA 3R, 4 and 4X environments
- Eliminates hotspots: high CFM fan with superior air flow, ideal for eliminating hot spots

4. Thermostats and hygrostats
(back to index)▲
Thermostats are used as temperature controllers and, therefore, for the control of Filterfan® or electrical
enclosure heaters. They are available with N.C. (normally closed) / N.O. (normally open) and changeover contacts. Twin thermostats are
switching units in various temperature ranges, they use less space than 2 single devices which saves energy and reduce costs.
In combination with control cabinet heaters you can ensure, besides temperature control, that the control cabinet is 'artificially' dehumidified, particularly in outdoor applications. That means that the temperature is kept above the dew point so that no water condenses out of the air, which could lead to short circuits due to the formation of condensation.
