At AHT Cooling Systems, we managed to successfully put this principle into practice by developing a semi-automatic defrost which works independently, on basis of the latest technologies and which nearly requires no manual effort. The hygiene of the freezer and also of the products stored within fully complies with the highest standards. As the defrosting of our static freezers is based on a sophistically timed sequence of heating periods in the innertank.
Frost build-up due to ambient humidity is successfully melted away at regular intervals - and this avoids any excessive frost build-up. Furthermore, during the thawing process, the temperature of the goods will always remain below –15 °C, hence fully complying with legal requirements. The use of a special divider system will prevent any adverse effects on the temperature of your goods and melted ice water collects in a duct that surrounds the inner case and is evaporated away outside of the storage area.
