To meet your requirements we have standard boilers and ability to customize a boiler.  Our market is for laboratory, small to medium barrel production rather than large production facilities. Our boiler models are narrow and compact, able to glide through a small doorway.  Reimers electric boilers are the most simple to install. For sizing purposes approximately 10KW of energy will be needed per barrel produced.  There is no chimney or outside venting required.  We offer blowdown tanks to make caring for your boiler very easy.
