Key Features
① Vacuum-Brazed Construction All plates are permanently bonded through a high-temperature vacuum copper brazing process — eliminating gaskets, preventing leakage, and withstanding operating pressures up to 3.0 MPa.
② Superior Heat Transfer Efficiency The asymmetric corrugated plate geometry creates turbulent flow at low Reynolds numbers, achieving thermal effectiveness up to 99% with a minimum approach temperature of just 1°C.
③ Ultra-Compact Design Delivers the same thermal capacity as a shell-and-tube heat exchanger at just 1/5 the size and weight — reducing installation space, piping costs, and structural load.
④ 316L Stainless Steel Plates Corrosion-resistant cold-rolled stainless steel construction ensures compatibility with water, glycol solutions, refrigerants (R410A, R32, R134a), and food-grade fluids.
⑤ True Counterflow Configuration Diagonal flow port design achieves genuine counterflow heat exchange, maximizing the log mean temperature difference (LMTD) and driving down energy consumption.
⑥ Maintenance-Free Operation No gaskets, no moving parts. The fully brazed structure requires zero routine maintenance and delivers a service life exceeding 20 years under normal operating conditions.
