HIF 690 and HIF 1200 flameless indirect-fired heaters use a diesel engine to generate heat, so the flame is completely isolated from the surrounding environment.
The Complete Heat System is for use with Serious Thermal Products’ Serious Toaster ground-thawing machines.
Toaster uses a patented infrared technology to thaw frozen ground up to 1.6 inches deep per hour in a 2x10-foot area.
Billed as having up to 75 percent net heater efficiency, Ground Heaters says the Arctic Bear Cub 300 indirect fired heater offers a maximum heat input of 288,000 Btu/hour at an airflow rate of 3,690 cubic feet per minute.
Model CH5000 Cross Heater is a portable hydronic heater designed for thawing, frost prevention, curing and air-heating applications.
