Introduction

The "COMPACT" range heat exchangers are at the heart of the ACTE company and of our success.


They were specially designed to improve gas turbines efficiency while remaining compatible with the specific requirements of this field :

​

  • Resist to major thermal shocks during startup;

  • Achieve high efficiency;

  • Ensure optimal integration;

  • Available from prototyping to high volume production and low unit cost;

  • Guarantee low maintenance costs.

MGT from 25 kWe to 1.5 MWe

Leveraging over 20 years of experience on the Micro Gas Turbine (MGT) market, the ATE recuperators technology is used on several hundreds of micro-gas turbines worldwide.

​

During those 20 years, ACTE worked actively on several dozens of MGT engines and studied hundreds of engines in total, which led the company to develop an extensive know-how and expertise regarding the specific challenges to be addressed during the development of a MGT.

​

Technical features of MGT projects for which ACTE are specially suitable :

​

  • 25kWe to 1.5 MWe micro turbines;

  • Recovered Brayton Cycle applications;

  • Critical volume for implementation;

  • Specific lifetime expectations.

 

It is in this context that the annular shaped ACTE recuperators were created and the unique profile of our heat exchangers was developed, giving our recuperators their exceptional features: reducing by half the turbine consumption, increased lifetime and resisting to thermal shocks.

For each new project, ACTE's team works together with their customer to find the best way to integrate the recuperator with your turbine: design of the recuperator and its interfaces, optimization of the fluid circulation and power system in order to reduce the pressure drops, ensure the expected efficiency and, finally, achievement of all of our customers' objectives.
