Jacketing Solution for Heating Valves, Instrumentation, Pumps, & Other Process Components


Since its introduction over 40 years ago, CSI’s ControHeat® jacket has been the preferred solution for heating valves, pumps, meters, fittings, flanges, and many other components. Mounting directly to off-the-shelf line-size equipment, ControHeat® jackets ensure uniform heat transfer to process components for the purposes of thermal maintenance, heat-up/melt-out, or cooling.

Each ControHeat® jacket is cast from ASTM B179 Grade A 356.2 copper-free aluminum to fit a unique piping system component. CSI maintains a pattern library for over 10,000 components, and new patterns can be made for almost any component. A carbon steel or stainless steel pressure chamber is embedded in the aluminum casting to contain the heating medium. The aluminum casting is not designed to hold pressure but only to promote uniform heat transfer around the piping component. A thin layer of heat transfer compound is applied to the inside of the ControHeat® to promote heat transfer between the aluminum jacket and the component.

Standard Features:

  • ControHeat® jacket body is cast from copper-free aluminum (ASTM B179 Grade A 356).
  • Pressure containing insert fabricated from carbon steel (ASME rated SA-178 Grade A Boiler Tube). S/S optional.
  • ControHeat® jackets are cast to “Fit Like a Glove” for specific process components.
  • Pressure and temperature ratings up to 600psig @ 750°F.
  • Thousands of ControHeat® patterns already in CSI inventory.
  • Digital component scanning available to simplify logistics of creating ControHeat® pattern, when required.
  • Optional Accessories Include ControCover Insulation Blankets and Flexible Pre-Insulated Jump-Over Hoses.


  • Reduces Long Lead Times: Eliminates long lead time for fabricated jackets and field guess work when using tube tracing.
  • Cost Effective: Most economical option when considering total installed lifetime costs and higher cost alternatives.
  • Complete Heating: Provides evenly distributed heating across entire component.
  • Easy to Install and Maintain: Eliminates the need for special flanges and potential component damage from welding. Quick and easy removal for access to process component compared to alternatives.
  • Reduced Operational Risk: Removes possibility of cross contamination (process heating media)
