ControHeat

ControHeat® Bolt-On Jackets for Valves, Pumps and Process Equipment

ControHeat is CSI’s engineered bolt-on jacket system developed to deliver uniform conductive heat transfer to valves, pumps, meters, fittings, flanges and other process equipment. Contoured cast aluminium jackets combined with a pressure-rated insert provide accurate thermal control without altering the component pressure boundary.

  • Design: Custom-cast aluminium jackets envelope the component with heat; high conductivity aluminum ensures a uniform jacket temperature and heat transfer compound ensure excellent thermal contact.
  • Heating medium: Compatible with steam, hot oil, glycol, and other thermal fluids; electric versions are also available.
  • Applications: All processes including liquids, gases, slurries, and solids.
  • Performance: Bolt-on installation with no welding required; jackets are removable for inspection and reuse.
  • Installation: Bolt-on installation with no welding required; jackets are removable for inspection and reuse.

ControHeat Vs. Tube Tracing

ControHeats envelop the component while tube tracing supplies line-contact heat. The engineered jacket approach improves temperature uniformity and reduces operational risk.

  • Uniform heating: Full-surface conduction minimizes temperature gradients and cold spots, resulting in a more consistent wall temperature than localized heating methods.
  • Predictable thermal performance: Conductive heat transfer provides steady, repeatable heating behavior, simplifying temperature control and reducing sensitivity to trace routing or contact quality.
  • Reduced localized overheating: Distributed heat input lowers the risk of hot spots commonly associated with electric heat tracing, helping protect product quality and component integrity.
  • Responsive heat-up and recovery: Direct conduction into the component mass enables efficient heat transfer for start-up and temperature recovery after process upsets.
  • Design flexibility: Custom-fit jackets accommodate a wide range of valve sizes, geometries, and assemblies, including complex or irregular components.

Why ControHeat Has Fully Replaced Jacketed Valves

ControHeat is widely accepted as a replacement for fabricated jacketed valves because it reduces weld-related failure modes, shortens delivery time and lowers lifecycle cost while maintaining consistent thermal performance on complex geometries.

Technical Advantages

  • No valve modification: preserves valve warranty and avoids heat-affected zone damage from welding.
  • Superior heat transfer: custom-fit oven-like enclosures ensure even heating on bonnets, stems and flanges.
  • Easy installation & maintenance: bolt-on, reusable jackets reduce downtime and lifecycle costs.
  • Shorter lead times: take advantage of the shorter lead time for standard valves.

Commercial Advantages

  • Lower total cost: Typical savings of 20–30% vs fabricated jackets due to no welding, reduced labor and reusable design.
  • Reliability: fewer failures, less downtime and proven long-term performance in demanding services.
  • Industry acceptance: trusted by process plants worldwide and widely adopted as a replacement for welded jackets.

Frequently Asked Questions

How is ControHeat different from tube tracing?
ControHeat provides engineered full-surface conduction via contoured aluminium jackets and heat transfer compound for maximum contact area. Tube tracing provides line-contact heat that can create uneven temperature profiles and cold spots on irregular shapes.
Does ControHeat require valve modification or welding?
No. ControHeat is bolt-on and non-intrusive. No welding or valve body penetration is required, preserving component metallurgy and manufacturer warranty.
What materials and pressure specification are standard?
Standard jackets are cast copper-free aluminium (ASTM B179 / A356) and pressure inserts are typically ASME SA-178 Grade A boiler tube. Stainless steel inserts are available for aggressive services. Design pressure follows applicable ASME and project specifications.
