Direct (Indirect) Electric Heater
Direct (indirect) electric heater is an electric heating system to heat the oil, natural gas and other combustible gas, widely used in oil and gas field, petrochemical application situation and offshore platform.
Application
There are two heating ways: direct heating and indirect heating.
In a typical processing train the sequence is: Feed → Separation → Outlet.
Scope of supply
- Direct electric heater uses U tube to heat the medium directly, while the indirect electric heater uses the heating core first to heat the heat conducting oil (heat transfer medium) and then heat the process medium.
- Direct electric heater consists of heating core, bearing shell and control system.
- Heat transfer oil heater is mainly composed of electric heating system, heat-conducting oil system and automatic control system.
- Having the characteristics of safety,reliability, stable control, long service life, easy operation and maintenance.
- Characteristics 3D System Characteristics It is suitable for various dangerous conditions, for example, explosive gas atmosphere Safe and stable heating process, easy control Using patent and original imported U electric heating tube The heating system can be automatically controlled, including the electric heating system control by DCS system with various safety protection functions High pressure shell（to the direct type）and atmospheric shell（to the indirect type）
Capacity, design conditions and scope of supply are confirmed per project.
