In a cold room working at -25ºC one of the evaporators drains clogged. The evaporator tray overflow and plenty of water felt on the floor forming a mountain of about 20 cm high and 80 cm in diameter . It do not allow circulation of the forklift or elevators to repair the drainage Electric resistance.(heater)


The client does not want to use salt (NaCl) to thaw the ice for corrosion problems on metal shelves.
What other ways could be used to melt or thaw the ice block ?
It has to be food grade and suitable for workers perform it in a closed and cold environment.

The costumer do not want use a chisel and hammer do to the fact the worker could damage the floor.
Thanks

Thats will do the job.

Very carefuly, just break the ice, do not dig, it will not damage the floor.
