The Güntner Benefit - fast cooling and freezing

  • High air circulation rate
    Güntner evaporators are equipped with high-performance brandname fans in forced-draught and aspiration versions. These fans ensure that the room is optimally penetrated with cold air. The GFN Blast Freezer has forced-draught fans that ensure even air distribution in the cold storage room. Goods on cold storage trolley cars and stacked goods are efficiently cooled with the fans’ horizontal airflow routing. With the GHN wall/ceiling-mounted evaporator the fans are inclined upwards by 3° (Güntner Incline Design). This increases the Coanda effect and optimises the airflow routing in the room.

  • High air speed
    Fast freezing is important in maintaining the chilled goods’ original properties, such as nutrient content, taste, smell and appearance. Fans with high air speeds must be used to achieve this. Güntner provides evaporators with high-performance fans and the corresponding external pressure for this. Please specify the required external pressure with enquiries.

  • High defrosting capacity
    The fin coil must be defrosted regularly to maintain the evaporators’ cooling power. The system’s cooling power must, however, continue to be guaranteed during the defrosting process. This can only be achieved with evaporators that are optimally equipped for fast and efficient defrosting. Güntner evaporators have electric heating for the coil, tray and fans as an option. A hot gas defrosting for the coil and the tray can also be selected for the GFN Blast Freezer.

  • Stepped fin spacing for reduced frost-forming on coils
    Güntner provides evaporators with the option of double fin spacing on the air inlet. This can be selected via the Güntner Product Calculator (GPC) configuration software. The double fin spacing prevents ice build-ups from blocking the fin gaps on the air inlet. Fewer defrosting cycles are then required, even in cold storage rooms with high air humidity and high floating temperature difference.
