Plate Heat Exchanger Manufacturer in Yemen South Africa

comparison between Gasketed Plate Heat Exchangers (GPHE) and Brazed Plate Heat Exchangers (BPHE)

1. Construction

Feature	Gasketed PHE (GPHE)	Brazed PHE (BPHE)
Design	Plates sealed with rubber gaskets and held in a frame	Plates are vacuum brazed (usually with copper or nickel) into a solid block
Serviceability	Fully disassemble; plates and gaskets can be removed and cleaned	Non-serviceable; sealed unit, cleaning is limited to chemical flushing

Flexibility

Plates can be added or removed to adjust capacity

Fixed design; capacity can’t be adjusted once built

Operating Conditions

Feature	GPHE	BPHE
Pressure	Moderate (< 25 bar typical)	High (up to 30–45 bar or more)
Temperature	Up to ~180°C (limited by gasket material)	Higher, up to 200–250°C depending on brazing metal
Fluids	Suitable for dirty, viscous, or particulate fluids	Best for clean, low-viscosity fluids (e.g., refrigerants, oils)
Fouling Resistance	Easier to clean and maintain	More prone to fouling due to narrow channels and no access for manual cleaning

Maintenance & Lifespan

Feature	GPHE	BPHE
Maintenance	Easy to clean and service regularly	Difficult to clean, must be replaced if clogged or damaged
Gasket Replacement	Required periodically (based on fluid and temperature)	No gaskets; fewer parts to replace
Durability	Long-lasting with proper maintenance	Durable, but can be irreparably damaged by corrosion or fouling

 Cost

Feature	GPHE	BPHE
Initial Cost	Generally higher	Generally lower
Operating Cost	Lower in long-term if regular cleaning is needed	Lower upfront, but may need full replacement if fouled or damaged
