Asphalt tank

Tank volume:8500L,this tank is with the advantages of
reasonable design, safe and reliable,fast heat-up.

Wave board in the tank could buffer the impact caused by
inertia in the transportation.

Thickness of 100mm insulation cotton covers the tank with
the good effect,cooling rate:≤12℃/8h

Stainless steel frosted board out of the insulation layer is
elegant and easy to clean.

The tank has asphalt level indicator and safety limit switch
to avoid dangers caused too much or too less asphalt.

With the absorption and discharge function,improve the
working efficiency.
