Understanding Printed Circuit Heat Exchangers (PCHEs)
PCHEs routinely operate at temperatures up to 850 °C and pressures up to 1,000 bar – far beyond the limits of traditional designs. The result is a rugged, leak-proof exchanger ideal for aggressive fluids and vibration-prone environments. In short, a PCHE is a groundbreaking compact heat exchanger for high-pressure, high-temperature duties.

Gaskets for Plate Heat Exchangers: What are They Made of?
Gaskets serve as the seal between each pair of plates. As the fluids enter the plate pack through the inlet ports, gaskets ensure they stay in their proper channels and exit through the correct outlets. By creating a tight seal, gaskets keep the two fluids completely separate and prevent any mixing. This separation is crucial: any leak or cross-contamination would drastically reduce thermal efficiency and could ruin product quality.

Why Plate Heat Exchanger Is More Efficient?
Plate heat exchangers (PHEs) are often the most efficient choice for heat transfer in modern industrial applications. By stacking many thin, corrugated metal plates, PHEs achieve enormous heat transfer surface per unit volume – often 100–200 m²/m³, compared to only 20–50 m²/m³ for a typical shell-and-tube unit. The corrugations in each plate induce turbulence even at moderate flow rates, yielding heat-transfer coefficients on the order of 3,000–7,000 W/m²·K for liquid-to-liquid service.

How to Design a Plate Heat Exchanger
Plate heat exchangers (PHEs) are compact units consisting of thin, corrugated metal plates stacked together. These plates create alternating channels for hot and cold fluids to flow. The fluids stay separate (thanks to gaskets or welded seals) and typically flow in counter-current mode, maximizing the temperature difference along the length.

How to Check if Your Plate Heat Exchanger is Blocked?
Blocked PHEs can significantly reduce performance, increase energy consumption, and lead to costly downtime or even equipment failure. Early detection is crucial for maintaining system integrity and optimizing operational costs. But how can you definitively tell if your welded or gasketed plate heat exchanger is blocked?

Why Choose HT-BLOC Fully Welded Plate Heat Exchanger?
Traditional plate heat exchangers (PHEs) use gaskets to seal between plates. While these designs are effective in standard conditions, they inherently limit performance at elevated pressures or temperatures and can degrade in chemically harsh environments. By contrast, the HT-Bloc unit uses fully welded plate construction, employing laser or plasma welding to bond metal plates without any gaskets within the heat transfer pack.

Step-by-Step Cleaning Process for Plate Heat Exchangers
Plate heat exchangers (PHEs) are vital components in various industrial processes, facilitating efficient heat transfer between fluids. Over time, these systems can accumulate fouling—such as mineral scaling, biological growth, and particulate matter—that impairs performance. Regular cleaning is essential to maintain optimal functionality and extend the lifespan of the equipment.
