AMMONIA DETECTORS IN FREEZER CHAMBERS.

Author(s) : LINDBORG A.

Summary

THE AUTHOR'S ATTENTION TO THE PRESENT DAY USE OF AMMONIA DETECTORS WAS MOTIVATED BY THREE REASONS: LARGE WAREHOUSES FOR QUICK FROZEN FOODS ARE BEGINNING TO AGE WHICH MEANS THAT WEAR AND TEAR WILL GRADUALLY INCREASE THE RISKS OF EQUIPMENT OR COMPONENT FAILURE ; WITH THE ADVENT OF AUTOMATION AND INCREASED MANPOWER COSTS, REFRIGERATION INSTALLATIONS ARE TENDING TOWARDS PARTIALLY UNMANNED OPERATION, HENCE LESS HUMAN SURVEILLANCE ; SAFETY IN THE USE OF AMMONIA IS NOW BEING INVESTIGATED BY INTERNATIONAL ENVIRONMENTAL PROTECTION AGENCIES. ONLY FEW TYPES OF AMMONIA DETECTORS ARE SATISFACTORY OR RELIABLE FOR USE IN COLD ROOMS OPERATING AT 248 TO 243 K (-25 TO -30 DEG C). THE DETECTORS ARE COSTLY AND THEY HAVE TO BE CAREFULLY LOCATED IN ORDER TO OPERATE EFFICIENTLY. FREQUENT CHECKINGAND REGULAR CALIBRATION IS NECESSARY. 100% DETECTION IS NOT GUARANTEED AND SINCE SOME DETECTORS ARE NOT FULLY DEPENDABLE, FALSE ALARMS OCCUR. A. H. S.
