This is a Raywall brand fan forced electric unit heater like those used in garages, industrial, workshops, etc. They are 15 kw rated, 240 volt 3 phase. I have 4 of these units. These sell for $1,800 each and up on the internet. These are used working models. Price is $100.00 each or if you want all 4 would be $375.00. Cash only.
