To comply with ATEX regulations, Gericke has undertaken, on all its feeders, a security assessment and got the necessary certificates by notified bodies. Feeders and loss-in-weight feeders can now be delivered for zones 1/21 and 2/22 outside, thus designed as equipment category 2 or 3, and category 1 for internal zone 2/20. In other words, the powder or dust should contain a minimal ignition temperature > 200°C, a layer ignition temperature of > 210°C and a minimal ignition energy of > 1 mJ.
