Air To Air Heat Exchangers

Efficient Cooling with Ambient Air

Cooling with ambient air is the most economical and energy efficient type of cooling. When ambient air is contaminated by dust, liquid or gases, the components which are integrated in the enclosure can be damaged if contact occurs. The use of a Filterfan® is therefore no longer recommended.

Due to the integrated heat exchangers a complete separation of the internal and external air flow is possible. The interior of the enclosure is thus hermetically separated from the atmosphere. Harmful dust and fluids can’t cause any damage to the integrated components any more. The εCOOL air/air heat exchangers are thus an alternative to filterfans.

Pfannenberg Air/Air Heat Exchangers are an ideal solution for these application areas with contaminated air:

  • A dual air circuit design keeps complete separation of the internal and external air
  • The interior of the enclosure is thus hermetically separated from the atmosphere
  • Harmful dust, gas or fluids can no longer cause damage to the integrated components
  • The robust steel construction of the air/ air heat exchangers makes their operation in harsh industrial processes possible

Pfannenberg’s εCOOL products feature a maintenance friendly design. Installation and maintenance of these units requires much less time compared to other closed loop products. The εCOOL Air/Air Heat Exchanger feature an energy efficient, minimal maintenance design that is a proven solution in harsh environments.

Why Choose Pfannenberg  Air/Air Heat Exchangers?

Filterless Design

Maintenance time can be minimized due to the wider fin spacing of the heat exchanger. If required a filter can be added to the unit at any time for more protection in harsh environments.

Energy Efficient

Cooling with ambient air is the most economical and energy efficient type of cooling.

Adapted to Extreme Conditions

A dual air circuit design keeps complete separation of the internal and external air. The interior of the enclosure is thus hermetically separated from the atmosphere. Harmful dust, gas or fluids can no longer cause damage to the integrated components.

Tool-Free Filter Change

Tool-free retrofit of filter adapter. Tool-free filter change in less than one minute.

Air to Air Heat Exchangers Models

PAI SERIES


20 – 100 W/°C
Ideal solution when the ambient air is too contaminated to use a Filterfan®

Efficient Cooling with Ambient Air

The εCOOL Air/Air Heat Exchanger feature an energy efficient, minimal maintenance design that is a proven solution in harsh environments.

Rugged Design

One piece steel cover design for manufacturing environments which protects internal components.

Energy Efficient

Ambient air is used for the thermal management of the enclosure.

Maintenance Free

Complete separation of the internal and external air flow and robust steel construction adapted to most environments (dust, solid particulate, vapors … ).

Filterless Design

Maintenance time can be minimized due to the wider fin spacing of the heat exchanger. If required a filter can be added to the unit at any time for more protection in harsh environments.

Reduced Fan Maintenance

Life expectancy of fans exceed industry standards. When replacement is required both fans can be removed from exterior to avoid lock out for maintenance and reduced MTTR.

Easy Mechanical Installation

Tool free mounting. Can be mounted by one person with our spring plate design. This unit also features a mounting-friendly seal, no elaborate reworking of the mounting cut-out.

Optimized Airflow Design

Long air path design efficiently delivers cool air below the critical components while removing damaging hot air from the top of the enclosure. The high volume of air flow will eliminate hot spots.

Integrated Thermostats

Primary mechanical thermostat can be used to adjust temperature, saving energy. The secondary thermostat can be used as an independent alarm set point.

Space Saving Integrated Design

Units have minimal depth off enclosure making door mounting feasible.

Easy Electrical Installation

Pluggable connection allows for wiring to be done before the unit is installed.
