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.
