	Industrial buildings - this device was created as a result of LEO ST or AGRO water heater expansion by an additional element – mixing chamber. Designed for the heating and ventilation of industrial halls and warehouses, pavilions and sports facilities.
	Control system - the apparatus consists of one type of control system: The KTS system allows stageless regulation of the throttling valves opening degree and a more accurate setting of the amount of air delivered in a range of 0-100%.
	Selection - in order to learn more about mixing chamber operations, the possibility of cooperation with LEO water heaters, alignment of throttling valves, appropriate choice of controls, etc.,contact FLOWAIR.
