25℃ Antifreezing Hydrant / Fire hydrant

25℃ Antifreezing Hydrant
25℃ Antifreezing Hydrant

A fire hydrant is an active fire protection measure, but the water in outdoor fire hydrant is always frozen in winter or in somewhere cold. It may causes the delay of fire fighting work and also some fire hydrants have the riskiness of burst.

Through adding a heating plate in the key part of the fire hydrant, this product keeps the temperature of fire hydrant at 25℃ ensuring that there is liquid water in fire hydrant all the time and makes use of solar energy reasonably.
