Steel Integra model boilers with new, patented retort burner made from high quality grey cast iron are intended for water central heating installations in open systems, as well as closed systems (after mounting a cooling coil with BVTS valve). Boilers constitute a steel structure welded from certified 6 mm thick boiler sheets that ensure a long-term use. Intended for burning eco-pea coal with 5-25 mm granulation. The handling of boiler is limited to kindling an automated hearth and removing ash. Automated hearth is cyclically supplied with small amounts of fuel fed directly to retort grate, while airflow fan supplies a precisely chosen amount of air into determined hearth zones. This allows to achieve high burning process efficiency and extremely low emission of harmful substances into atmosphere. The correct progress of burning process and maintaining a set boiler temperature is supervised by microprocessor regulator with novelty software. The controller handles CH and DHW pumps, as well as auxiliary pump. There is a possibility to connect room regulator and ST-65 GS M and ST-500 Ethernet (control via Internet) modules, as well as ST-61 (possibility to control two valves at once) module.
