HeatCell's advanced proprietary heating system known as Encapcellon Technology™ offers high-performance, long-burning heat with specialized fibers that encapsulate and concentrate the fuel combustion at the top of the can. This unique spill-resistant combustion process enables the flame to remain at a consistent distance to the bottom of the heating equipment.  Should the can fall face down, it safely extinguishes, eliminating the risk of fuel leaks and burns.  The odorless, clean burn eliminates carbon buildup and offers the lowest CO emissions available.  Easy to relight for significant cost savings and reduced waste.  HeatCell's non-flammable classification has no special storage requirements or shipping restrictions.
