Antifreezing Hydrant / fire hydrant

Antifreezing Hydrant
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 cause 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.
