Rittal Climate Control Solutions

Buying Guide



Heat is the enemy of extending the life of your electronics. Heat attacks your equipment from all sides: on the outside with extreme variations in ambient temperatures and inside with high thermal loads caused by the high density of components within the enclosure. The challenge is to manage temperatures consistently on both ends of the thermal spectrum in any environment.

Rittal industrial climate solutions lengthen the life of your components, optimize performance and reduce equipment failure. Time is money, and uptime ensures your operations are profitable.

Air Cooling Solutions

TopTherm Fans & Filter Units

Everything about TopTherm is designed to be simple. TopTherm filter fans’ quick-fit technology enables them to easily snap into prepared mounting cutouts. Additionally, reversing the fan motors to change the airflow direction is just as easy. The easily accessible louvered grill latches ensures effortless and efficient replacement of the filter mats, with no supplementary tools required. Rittal also ensures that TopTherm is globally compatible with any existing cabinet and enclosure product range. This makes the switch as simple as possible and preserves all existing throughput ratings and installation dimensions.


Features and Benefits:

  • NEMA 12 out of the box, and NEMA 3R/4/4X with the rain hood
  • Tool-free assembly
  • Air cooling throughput from 20 to 700 m³/h
  • A full range of available voltages bring cooling to any configuration
  • New diagonal air flow technology for higher volume and more consistent cooling within the enclosure
  • Minimum installation depth
  • Intelligent symbiosis of radial and axial fan technology
  • Nano-coated Condenser
  • Air flow spreads diagonally from the fan, promoting a more even air distribution in the enclosure

Wall-Mounted, UL Listed, Type 3R/4 Air Conditioning Units

Rittal’s Blue e, Wall-Mounted, UL Listed, Type 3R/4 air conditioning units are an excellent choice for indoor or outdoor enclosures where water is an issue, such as waste water facilities, transportation and toll booths, outdoor kiosks and food and beverage facilities. These air conditioners provide protection from the harmful effects on equipment due to the presence of water and external formation of ice. Rittal’s use of nanotechnology helps resist filiform corrosion on condenser coils which offers greater energy efficiency. The coated condenser coils do not affect the cooling capacity of the unit and in most cases a filter is not required. This also enables longer intervals between service maintenance.

Rittal’s closed loop system maintains a Type 3R/4 rating and creates an environment in the enclosure that is cooler inside than the surrounding temperature. With an internal temperature set point of 35 °C, Rittal air conditioners are designed to operate at temperatures up to 50 °C.

Features and Benefits:

  • Type NEMA 3R/4 for either indoor or outdoor use and provides protection from water, rain, sleet and snow
  • Saves up to 45% in energy consumption
  • Vandalism resistant controller located inside enclosure
  • Rittal’s Comfort Controller for superior information display
  • Functionality and capacity tested before shipment to ensure trouble free operation
  • cUL US Listed
  • Total cooling output of 0.50-2.50 kW
