Plate and Frame Heat Exchangers

Plate heat exchanger vs Shell and tube heat exchanger Feature Plate Heat Exchanger (PHE) Shell and Tube Heat Exchanger (STHE) Compactness & Space Very compact. High surface area to volume ratio. Saves significant space. Bulky and large. Requires more floor space and headroom. Heat Transfer Efficiency Very high. Turbulent flow at low Reynolds numbers ensures high heat transfer […]

Key Advantages of Titanium Plates Choose titanium plates when:

Titanium plates in a heat exchanger primarily when you need outstanding resistance to corrosion, especially from chlorides, seawater, and other aggressive media, and the cost is justified by the extended equipment life and reliability. The decision is rarely based on strength or weight, but almost exclusively on chemical compatibility. The Primary Reason: Chloride Resistance The single most common reason […]

Scenario Recommended Type Reason Clean fluids (water, oils), moderate T&P, need for cleaning/inspection Gasketed Plate (PHE) Cost-effective, serviceable, and flexible. High pressure/temperature, corrosive media, no fouling Brazed Plate (BPHE) Compact, sealed, and cost-effective for its duty. Very high P/T, aggressive media, abrasive particles, high reliability Welded Plate (WPHE) Handles the most severe conditions while maintaining […]

You choose a Welded Plate Heat Exchanger when your application demands the efficiency and compactness of a plate design but operates under conditions that are too severe for gaskets. It is the robust, heavy-duty solution that bridges the gap between gasketed plate exchangers and shell-and-tube exchangers. The Core Decision: When to Choose a Welded Plate Exchanger Think of […]

Brazed (BPHE) vs. Gasketed (PHE): Feature Brazed Plate Heat Exchanger (BPHE) Gasketed Plate Heat Exchanger (PHE) Construction Permanently brazed plates. Plates held by bolts in a frame with gaskets. Serviceability Cannot be opened. Unrepairable. Fully serviceable. Plates can be cleaned, gaskets replaced. Pressure/ Temp Very High (e.g., 45 bar, 200°C+) Moderate (e.g., 25 bar, 150°C) – limited […]
