The Bolt-in is the best way to introduce heat into an existing tank in the field. No need to steam your tank, the Bolt-in is simply installed through the manway of the tank and bolted into place. Heated using flameless, explosion proof heaters, the Bolt-in is designed with between 10,000BTU/hr to 40,000BTU/hr of input energy.
