MECS® Custom Engineered Heat Exchangers

Maximum Energy Efficiency

As a world leader in the design and construction of sulfuric acid plants, Elessent Clean Technologies offers a range of solutions to meet customer needs for acid cooling.  We approach each project to optimize performance and reliability, and to address the unique concerns of every individual plant.  Each acid cooler is custom designed to meet your specific process conditions.

Gas-gas plate heat exchangers are key components in a variety of today’s modern chemical plants.  MECS® exchangers are custom engineered and designed with leading plate technology, offering the most efficient means on the market for recovering heat from energy consuming processes.

We Offer Three Types of Gas-Gas Plate Heat Exchangers to Meet Your Specific Needs


MECS-ThermoZ™ is a fully welded plate exchanger designed for use in traditional air preheat applications to recover heat from energy consuming processes.  The MECS-ThermoZ™ is a highly efficient heat exchanger suitable for many industrial processes where gas temperatures may be up to 1,500 F (815°C). 

MECS® Monplex II

MECS® Monplex II™ is a fully welded plate heat exchanger, designed to withstand the harsh conditions present within a sulfuric acid plant. The MECS® MonPlex II™ plate heat exchanger offers reliable operation, excellent process efficiency and cost effectiveness for sulfuric acid plants.


MECS® OCAP™ is a non-welded, floating plate pack designed for rapidly fluctuating process conditions.The MECS® OCAP™ non-welded plate heat exchanger is a customized, modular air preheater which delivers impressive energy efficiency and process savings.
