Defon provides highly efficient and reliable hydrogen coolers for thermal and nuclear steam turbines, as well as gas turbine generators. Featuring proprietary enhanced heat transfer, zero-leakage design, and high seismic and fatigue resistance, they are perfectly suited for the demanding operations of 1,000 MW power units.
Performance: Features proprietary curved vortex generators and anti-blocking turbulent fins, boosting heat exchange efficiency by 10.9%. This ensures precise temperature control, energy savings, and anti-clogging performance.
Structure: Utilizes an expanded and welded joint to isolate media, with a curved turbulent flow design tailored to specific operating conditions.
Reliability: Supports customized helium leak testing, natural frequency inspection, hydrostatic pressure testing, and non-destructive testing (NDT).
Maintainability: Designed with a modular pull-out structure for easy maintenance without disassembling the main unit, effectively minimizing downtime losses.
