Description

The 10″x20″ Brazed Plate Heat Exchanger (BPHE) offers compact, high-efficiency liquid-to-liquid heat transfer.
Engineers stack multiple corrugated 316L stainless steel plates and join them permanently through vacuum brazing.
The chevron pattern on each plate creates strong turbulence.
This design boosts heat transfer rates and keeps pressure drops low.
As a result, these units outperform traditional shell-and-tube exchangers in many applications.

The gasket-free brazed construction eliminates leak risks.
It also resists vibration and thermal shock effectively.
These exchangers handle pressures up to 450 psi and temperatures from –256°F to +437°F.
Their small size (about 9.8″ wide by 20.3″ long) fits tight spaces easily.
Low internal volume allows fast thermal response and reduces fluid needs.

Installation Procedures

Step Installation Procedure
Location & Mounting Install in a clean, accessible area with adequate space for piping and maintenance. Use the four built-in mounting studs on the front cover or optional brackets/frames. Ensure the unit is level and properly supported.
Orientation Can be mounted vertically or horizontally. For optimal performance and air venting, vertical mounting with counter-flow configuration is recommended.
Piping Connections Connect inlet/outlet ports using appropriate fittings (1-1/2″ or 2″ MPT). Use wide port spacing advantage. Install shut-off valves, pressure gauges, and thermometers on both sides. Ensure counter-flow arrangement for maximum efficiency.
Filtration & Protection Install strainers or filters on both fluid sides to prevent debris from entering the narrow channels. Add expansion tanks and pressure relief valves as needed for closed systems.
Initial Flushing & Filling Flush both sides thoroughly with clean water before operation. Fill the system slowly to remove air. Check for leaks at all connections.
Startup & Testing Start pumps at low flow, gradually increase to design rates. Monitor pressure drop, temperatures, and for any unusual noise or vibration. Verify performance against design specifications.

Maintenance Procedures

Activity Maintenance Procedure
Daily / Weekly Checks Monitor inlet/outlet temperatures, pressures, and flow rates. Check for unusual noise, vibration, or external leaks. Record pressure drop across the unit.
Monthly Inspection Inspect all piping connections and mounting points. Verify strainers/filters are clean. Check system fluid quality (pH, hardness, and treatment levels).
Quarterly Maintenance Clean or replace suction strainers. Perform a visual inspection of the heat exchanger exterior. Measure and record pressure drop to detect early fouling.
Annual / As Needed Chemically clean (CIP) the unit using approved descaling solutions if pressure drop increases or performance drops. Flush thoroughly afterward. Inspect for corrosion.
General Recommendations Always maintain proper fluid treatment and filtration. Do not exceed design pressure or temperature. Never disassemble the brazed unit. Keep spare strainers and cleaning chemicals on site for quick response.
Winterization (Cold Climates) Drain or use glycol mixtures in systems exposed to freezing temperatures. Follow manufacturer guidelines for long-term storage.

Q&A

Question Detailed Answer
What is a 10″x20″ Brazed Plate Heat Exchanger? It is a compact, high-efficiency heat exchanger made of multiple 316L stainless steel plates vacuum-brazed with copper. The “10×20″ refers to the nominal plate size (~9.8″ x 20.3”). It transfers heat between two fluids without mixing them, using a chevron pattern for turbulent flow and superior performance.
What pressure and temperature can it handle? Design pressure up to 435–450 psi (30 bar) and temperature range from -256°F to +437°F (-160°C to +225°C). It is ideal for high-pressure hydronic and industrial systems.
How many plates are available? From 10 plates (small residential) up to 200+ plates for large commercial/industrial duty. More plates increase heat transfer area and capacity.
What are typical connections? 1-1/2″ MPT for smaller units and 2″ MPT for larger plate counts. Wide port spacing (~6.75″ center-to-center) simplifies piping installation.
Can it handle solids or dirty fluids? It performs best with clean fluids. Use proper filtration and strainers. Fouling reduces efficiency; chemical cleaning (CIP) is recommended as the unit cannot be disassembled.
Is copper brazing suitable for all applications? Copper is excellent for most water and hydronic applications. For aggressive fluids (high chloride, ammonia, or seawater), choose nickel-brazed versions for better corrosion resistance.
How does it compare to shell & tube exchangers? Much more compact (often 1/5–1/6 the size), higher efficiency, lower hold-up volume, and easier installation. It is also lighter and requires less space and insulation.
What maintenance is required? Very low maintenance. Keep fluids clean, check for pressure drops periodically, and perform chemical cleaning when needed. No gaskets to replace.
Common applications? Outdoor wood boiler isolation, radiant floor heating, domestic hot water, pool/spa heating, snow melt, refrigeration evaporators/condensers, geothermal, and industrial process cooling.
What approvals does it typically carry? UL Listed (standard), with optional ASME, CRN, and CE/PED certifications for code-compliant installations.
