Inquiry (采购产品): heating sulphuric acid tank We have a sulphuric acid bulk tank (approx 6,000) gallon (vertical) that is causing problems with the extended cold weather. The suction line on the tank is frozen and we are looking for a long term solution short of building a heated structure around the tank. **** Hidden Message ***** george asplund 73701 Company: luckinbill, inc.
