EnviroVault Bolt-in (Retrofit Heat)

"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. Available with coating to the “wetted” area, the Bolt-in comes ready to use for any application. "

EnviroVault Catalytic Heaters

Infrared gas catalytic heaters are the industry standard for heating in hazardous locations. Specifically designs to be robust & long lasting, these heaters are the market choice for oil and gas applications. These explosion proof heaters do require electricity for initial start up but operate continously on Natural Gas or Propane after that. EnviroVault has been using Catalytic heaters to provide freeze protection and temperature maintainance on 1000's on tanks throughout North America. Through R&D testing and field calibration, we have developed models to size the heaters for any application.

Heated EnviroVault

Heated EnviroVaults use flameless explosion proof heaters mounted within a chamber installed 'inside' an above ground storage tank. Used for either freeze protection or for maintaining process temperature , Heated EnviroVaults have many advantages. Ranging in size from 10,000BTU/hr up to 240, 000BTU/hr this heating system provides exceptional heat transfer while using low volumes of gas making the Heated EnviroVault one of the most efficient tank heaters on the market.
