Low temperature pretreatment saves £5000 net per year for International Harvester

Low temperature metal surface cleaning and phosphating processes developed by Pyrene Chemical Services Limited are saving £8370 per year in energy costs at the Bradford factory of International Harvester Company of Great Britain Limited. Pyrene Bonderite 299 low temperature phosphating and Pyroclean 499 low temperature cleaner were introduced into the pretreatment line a year ago after careful test runs to establish what the potential cost‐savings would be. These savings have been confirmed in practice.
