Product Overview
EOU® compact fully‑welded plate‑and‑shell heat exchanger combines the high heat‑transfer efficiency of plate‑type heat exchangers with the high‑temperature & high‑pressure resistance of shell‑and‑tube heat exchangers. Adopting advanced laser‑welded corrugated plate bundle as core heat‑transfer element, this gasket‑free unit creates two independent fluid flow channels inside the shell. It delivers intensive turbulent flow under counter‑current condition to maximize heat‑transfer performance. Compact footprint, reliable sealing and flexible customization make it a premium choice for complex industrial thermal transfer processes.

Application Fields
General Industrial Machinery
Suitable for heating, cooling, evaporation, condensation and waste‑heat recovery of liquid & gas media. The corrugated plate structure resists thermal shock and pressure fluctuation, widely deployed as supporting equipment for complete industrial production lines.
Refrigeration Industry
Work as evaporator, condenser, condensing‑evaporator, superheated steam desuperheater and oil cooler. Compact construction reduces refrigerant filling volume, perfectly compatible with ammonia, CO₂ and other natural refrigerants.
Power & Marine Energy
Gasket‑free fully‑welded design minimizes maintenance workload. Wide temperature‑pressure adaptability enables stable performance for waste‑heat recovery and marine‑on‑board thermal processes.
Petrochemical & Chemical Industry
Inherit merits of both plate‑type and shell‑and‑tube exchangers. Capable of high‑temp / high‑pressure process duties; fully‑welded structure adapts to diverse corrosive media. It helps save cost for expensive noble alloy material consumption.
Pharmaceutical & Food Processing
Supports liquid‑liquid, steam‑liquid, gas‑liquid, gas‑gas heat‑transfer duties. Special wide‑gap plate channels handle process fluids containing solid particles and fiber‑laden suspensions for heating and cooling.
