Product Description
The Aidear Copper Brazed Plate Heat Exchanger series delivers exceptional thermal efficiency in a ultra-compact, gasket-free package. Manufactured with corrugated 316L stainless steel plates vacuum-brazed using high-purity copper filler, these units create strong, leak-proof channels that maximize turbulence and heat transfer while resisting corrosion from water, glycols, refrigerants, and mild chemicals. The palletized stacks in the warehouse photo highlight ready-for-shipment quality—featuring precision-machined stainless ports, consistent plate alignment, and robust construction for bulk OEM or project use.
This design outperforms traditional shell-and-tube exchangers in size (up to 80% smaller), weight, and refrigerant hold-up volume, making it ideal for modern, space-constrained systems.
Product Type: Copper Brazed Plate Heat Exchanger (BPHE) / Vacuum Brazed Stainless Plate Exchanger
Plate Material: AISI 316L Stainless Steel (standard for excellent corrosion resistance; 304 or SMO 254 options for specialized needs)
Brazing Filler: Pure Copper (99.9% for optimal conductivity and strength; nickel alternative for ammonia or highly aggressive fluids)
Port Connections: Stainless Steel threaded (NPT/BSP), soldered copper, or flanged; sizes from 3/4" to 4" customizable
Operating Fluids: Water, glycol solutions, refrigerants (R134a, R410A, R404A, R32), thermal oils, steam (low amine content), hydraulic fluids
Pressure Rating: Up to 45 bar (standard); high-pressure models available for demanding applications
Temperature Range: -196°C to +225°C (copper brazed limit; customizable per media)
Flow Configuration: Counterflow or parallel; single/multi-pass; plate quantity adjustable for exact capacity
Options: Mounting feet, insulation covers, special port orientations, double-wall safety designs, PED/ASME certification
Copper brazing ensures superior metallurgical bonding at every plate contact point, delivering high heat transfer coefficients, low approach temperatures, and excellent fouling resistance in clean services. The corrugated plate pattern promotes turbulent flow for self-cleaning action and peak efficiency. With no gaskets or bolted frames, these exchangers are virtually maintenance-free, vibration-resistant, and suited for high-pressure/temperature cycles—reducing installation costs and system footprint dramatically.
