Our history

In 1963 the Lindau company Sulzer-Escher Wyss started to produce the first grain cooling devices for grain and oilseeds. Sulzer Escher Wyss was a factory for refrigeration equipment, thus perfectly equipped with the knowledge needed for the production of grain cooling equipment. Sales of these devices began under the name GRANIFRIGOR™, the start of a success story.

Cooled grain does not develop moulds and insects and respiration is minimised, to name the most important advantages. The benefits of conservation cooling quickly gained attention, not just in German-speaking countries, but internationally as well. The company developed into the market leader in the grain cooling sector. In 2005, the company FrigorTec took over the product area of refrigeration, including grain cooling equipment.

Our know-how

Specialised grain know-how was obtained through close contact with institutes and universities. The scientific basis was developed in cooperation with the Institut für Landtechnik (Institute for Agriculture Technology) in Bonn, the Düsseldorf University and the Bundesanstalt für Getreide (Federal Grain Research Institute) in Detmold. In addition specialised knowledge regarding conservation cooling was further developed in numerous scientific studies and measurements in grain storage facilities. For example, FrigorTec supported an evaluation for the analysis of the counterpressure of bulk grain of the University of Stuttgart-Hohenheim, completed in February 2013, which delivered very interesting results.

Continuous dialogue with storage operators, for example BayWa, feed operations, large and small mills, malt houses, seed companies and the Raiffeisen cooperatives, is an important contribution to the broad, comprehensive GRANIFRIGOR™ product series from FrigorTec.

The series is characterised today by a modular basis with a wide range of possible additions. The "modular system" includes options for remote data transmission, sound insulation, forklift slots, remote sensors, and complete rodent protection. For use in tropical climate zones, a special "Tropic" series was developed, as well as a "Desert" type for extremely hot, dry regions. Depending on the requirements, the grain cooling devices are also equipped for different types of electricity.

The wide range of solutions available today was developed, manufactured, tested and marketed by generations of specialists. It is this extensive experience that makes all the difference for the core competency of the world market leader: To this day, competitors have not been able to catch up with the specialised knowledge that FrigorTec has continuously expanded and updated.

Another thing: All GRANIFRIGOR™ grain cooling devices are "Made in Germany". They are built in the main FrigorTec factory in Amtzell (Germany).

The benefit to you

GRANIFRIGOR™ grain cooling devices have a wide range of impressive features:

  • Reliable use in all environmental conditions
    Whether rain, heat or cold: The compressors deliver a high level of cooling power with an optimal capacity rating. The automatic features of HYGROMAT™ regulate the humidity safely and reliably. Robust industrial models, completely enclosed, protect against external influences. Speed-controlled condensed water fans for trouble-free start-up in low outside temperatures. Thanks to the safety refrigerant, the products are also suitable for high outside temperatures.
  • Quality control with factory trial run
    Each device is tested and inspected in the technical department after production under customer conditions. In order to ensure short delivery times, common types are available on stock at all times.
  • A wide range of operating modes
    The Siemens DDC controller S7 and the microprocessor controller make possible the operating modes "whisper operation", "fast cooling", "ventilation mode" and "normal mode". All operating modes can be set manually or pre-timed fully automatically.
  • Easy to clean
    Large, efficient filters make cleaning easy. The filter monitor is integrated.
  • Low noise
    Thanks to sound-optimised fans and compressors, all types are very quiet. The "whisper" operating mode reduces the sound level even further.
  • Important standard features
    In addition to BMEP models for fans (ideal for tower silos), HYGROTHERM™ heat registers are also included in the standard scope of delivery.
  • Highly environmentally friendly & energy efficient
  • Only environmentally friendly safety refrigerants without CFCs or HCFCs are used. Energy-efficient fast cooling in booster mode as well as energy-efficient design with frequency-control are possible.

Additional features

  • Rotating-field and counterpressure display
  • Cool stop
  • Winter and summer thermostat to save energy
  • Electrical heater for use in cooler ambient conditions
  • View window in air cooler
  • Inspection opening in air duct
  • Anti-corrosion protection with coated heat exchanger
  • Stainless steel drip tray
  • Available with chassis with pneumatic tyres or castors
