7.2 Heater element casing The heating element casing consists of two half- shells in aluminium alloy. The shells are joined together by screws and sealed with silicone. The casing is insulated by two half-shells in basalt rock wool encased in a sheet of aluminium and secured by two straps. The air is heated by two heating elements. During delicate drying, one of the heating elements is switched off. The casing is fitted with thermostats that control the temperature of the air.
