Blast furnace for liquid (GPL) or methane gas (specify when ordering), with forced air ventilation of 28000 Kcal/h. Heavy-duty metal frame. Tilting crucible chamber with lid, lined with refractory material with high aluminum content and composed of easy-to-replace prefabricated elements. CE approved burner with pilot flame, safety valve and thermocouple. The wide, enveloping flame with tangential entry heats the blast furnace chamber without directly hitting the crucible. Heating times are extremely short. Burner ventilation is ensured by a silent electric fan. Technical Specifications: - Maximum temperature = 1350° - Inside furnace dimensions = ø 175 x 195 mm - Crucibles capacity = 3 kg/Cu - Burner consumption (GPL - Methane) = kg 2,3/h - 3,2 m3/h - Electric fan voltage = 230V, 1~, 50 Hz / 260 watt or 400V, 3~, 50 Hz / 260 watt
