Why CATCO Heated Enclosure Packages

Catco enclosure packages are the most efficient form of freeze prevention on the market. By heating the valve or regulator itself instead of heating the gas, you get much better heat transfer than other methods:

  • Catco enclosures provide more heat and easier access to the valve than with heat tracing.
  • Catco enclosures provide a much lower installation and operation cost than methanol injection
