The energy conversion module (ECM)

Modular heat exchanger stacks

Compact and flexible energy recycling module solutions, completely tailored to your needs and system requirements is what we offer you with our modular approach. With cellplates in different sizes we build stacks. With these stacks we build the modules that meet your requirements in both size and capacity. Right-sized and bespoke! Discover your benefits here or contact us to learn about the solutions we can offer you.

Flexible design base

BOSAL ECI has developed thin, stainless-steel plates in different sizes. These profiled plates are welded together to form a stack.

As a result, the stack performance -and thus its size- can be customized by: 

  • the size of the profiled plate
  • the number of plates welded together

    The size and number of stacks are determined by your system requirements.

Housing & interfaces

Based on your precise specifications, we not only develop and build your Energy Recycling Modules, but also the necessary housing with all the required interfaces to optimize routing and interaction forces:

  • Manifolds
  • Bellows
  • Clamps
  • Seals

We even provide complete exhaust systems with integrated after-treatment systems and high-temperature heat exchangers.

Full integration

With their compact, efficient construction, our Energy Recycling Modules can be fully integrated into your system.
