Our Products


SEICO designs high performance heaters which have several parallel ring gaps arranged such that the heating medium flows in predefined channels. The surface temperature is kept within narrow limits to ensure that the maximum operating temperature is not exceeded during normal operation. The MSR technology used ensures an efficient heating system with precise temperature control.

  • Compact design, high heat transfer efficiency and low maintenance
  • Annular gap technology used in the heaters allows control of heat-related processes in such a way that heat transfer oils can even reach the limits of thermal stability. As a result, we reliably prevent overloading (cracking) of the thermal oil
  • The multi-annular gap technology differs from the annular gap technology by the simultaneous flow through many annular gaps in a jacket tube
  • Minimal infrastructure and little space required with high performance, reliability and maximum availability
  • Ability to engineer and manufacture systems according to client’s specifications with our modular design
  • Maximum operational safety and environmental compatibility (due to the possibility of mechanical cleaning instead of chemical cleaning)
