Circulation & In-Line Heaters

Indeeco's circulation and in-line heaters are specifically designed for each unique process application, maximizing performance and reliability.

Benefits of using Indeeco circulation and in-line heaters

Indeeco has been manufacturing circulation heaters since 1929.  Aside from our long history there are two main advantages to using an Indeeco circulation heater.

• Customized for your application: Each application is unique in that process parameters differ.  By selecting a custom heater you guarantee that the heater will operate and perform at a level that delivers your desired process requirement.
• Consultative approach to design: When you chose to work with Indeeco, you'll be working directly with an electric heating expert.  We'll work to understand your unique application and understand your desired process outcome.
