火急求助：SPAL是什么

客户有要求SPAL，不知道是什么东西？请大侠赐教。原文如下（最后一句）：
They also would like some information on the blow molding facility that would make these. Please advise some specifics for:
Are gas tanks their main production?
Who do they manufacture for?
Size of factory?
# of employees?
Does the factory do the fluorinating in house or is it done somewhere else? Who does it?
Are the tanks treated to SPAL specifications?
