FIELD: engines and pumps.
SUBSTANCE: invention relates to a device for supply of a liquid reducing agent for treatment of spent gases. The device comprises at least one reservoir (1) with a bottom (5) and a device (8) of supply for a liquid (2). The supply device (8) is located in a chamber (9) on the bottom (5) of the reservoir, and a chamber (9) has at least one heater (29). The reservoir (1) has at least one local ventilation heater (40), stretching from a drain (10) for the liquid (2) on the bottom (5) of the reservoir at least one side (6) of the reservoir to the area near the closure (7) of the reservoir, and capable of creating at least one channel in the frozen channel near the bottom (5) and at least one side (6) of the reservoir, and thus prevent pulling of vacuum in the area of bleed during suction of the already melted liquid (2).
EFFECT: improved heating, as a result of which targeted and sufficient unfreezing of a frozen reducing agent is achieved in a short time after the start.
