A plate heat exchanger must match temperature approach (down to 1 °C), pressure drop, fluid chemistry, and gasket boundaries; the wrong plate pack fouls, leaks, or misses duty.
YONGFAN BR Series features 10 principal plate sizes (0.02 to 1.3 m²/plate, 0.2 to 500 m² assembly area), wide-gap BRb models for fiber/solids, and specialized metallurgy (Titanium TA1, Hastelloy, RS-2).
If primary supply temperature drops or the required approach tightens, the same plate count cannot achieve secondary target output without added surface area.
Aggressive chevron angles raise heat-transfer coefficients but multiply hydraulic resistance, starving circulating pumps of design flow.
Thin 0.5–0.8 mm stainless plates perforate rapidly under seawater or process acids. Titanium TA1 or Hastelloy must be matched to fluid chemistry.
Fibrous or particulate-laden media bridges narrow channels. YONGFAN BRb wide-gap free-flow plates are required to prevent clogging.

*Wide-gap free-flow models (BRb0.5, BRb0.7, BRb0.9) available for media containing fibers or suspended solids. Unequal 2:1 channel area ratio option available for asymmetrical HVAC flow duties.
Primary inlet/outlet (°C) and secondary inlet/outlet (°C).
Total heat load (kW / MW) or mass flow rates on both circuits.
Design pressure (1.0/1.6/2.5 MPa) and allowable pressure loss (kPa).
Fluid type, chloride content, viscosity, solids, and pH.
YONGFAN engineers will calculate plate count, channel velocity, pressure loss, and provide complete GA drawings.
Plates are pressed with precision tooling to ensure uniform corrugation depth, consistent wall thickness, and precise contact points.
Five-point positioning maintains perfect plate pack alignment under heavy clamping loads without gasket displacement.
Every assembled unit receives hydrostatic pressure testing at 1.25× design pressure along with single-side leak tests.
Replacement plates and pre-molded clip/glue gaskets are stocked for quick dispatch and easy field expansion.
BR1.3, with 1.3 m² per plate, 130–500 m² assembly area, maximum flow of 900 m³/h, and DN250 connections.
Yes. YONGFAN’s gasketed clamped-frame design allows plates to be added or removed within the available frame clamping capacity.
Titanium TA1 is documented for high-chloride solutions such as seawater. Confirm chloride levels and operating temperature.
EPDM is the standard route for water systems (-50 to 150 °C). Check water treatment chemicals before final selection.
Review the BRb0.5, BRb0.7, and BRb0.9 wide-gap free-flow models, specifically designed for media with particulates.
Down to approximately 1 °C in full counter-flow configuration, depending on duty, allowable pressure drop, and plate area.
A bare BR frame does not include pumps or make-up. For full pre-piped skids, select Packaged Units (ZS/ZW).
Hard domestic water scaling in narrow channels is better served by Floating-Coil Storage Exchangers.
Do not use standard narrow chevron plates for fibrous media without upgrading to the BRb wide-gap series.
While design limit is 170 °C, long-term continuous operation is recommended at ≤150 °C to preserve gasket life.
Send your four design temperatures, thermal load, allowable pressure drop, and fluid chemistry. YONGFAN application engineers will verify plate area, model size, and provide dimensioned submittal drawings.
