Exchanger Type
Shell-and-tube, plate-and-frame, brazed plate, air-cooled, spiral, and specialty designs.
Heat Exchanger Buying Guide
Select a heat exchanger around thermal duty and fluid behavior.
Compare heat load, approach temperature, fluid properties, pressure, fouling, corrosion, materials, cleanability, footprint, pressure drop, and maintenance.
Buying Overview
Start with the actual operating requirement.
Heat exchanger selection requires accurate thermal and process data. Buyers should define inlet and outlet temperatures, flow rates, heat load, pressure limits, allowable pressure drop, fluid properties, fouling tendency, corrosion risk, cleaning method, space constraints, and code requirements before choosing a design.
Supplier Comparison
Capabilities and specifications to review.
Use the same technical and commercial criteria across suppliers so quotes and recommendations can be compared on an equivalent basis.
Thermal Duty
Heat load, approach temperature, overall coefficient, effectiveness, and operating range.
Fluid Behavior
Viscosity, fouling, solids, phase change, velocity, shear sensitivity, and contamination.
Pressure Drop
Available pumping pressure, channel velocity, fouling tradeoffs, and system impact.
Materials
Stainless steel, carbon steel, copper alloys, titanium, nickel alloys, plastics, and gaskets.
Cleaning
CIP, mechanical access, removable bundles, plate disassembly, chemical cleaning, and inspection.
Mechanical Design
Pressure, temperature, thermal expansion, vibration, nozzle loads, supports, and codes.
Supplier Support
Thermal calculations, drawings, testing, documentation, replacement parts, and field service.
RFQ Preparation
Provide enough information for an accurate recommendation and quote.
Thermal Data
Provide inlet and outlet temperatures, flow rates, heat duty, and expected operating range.
Fluid Properties
Specify composition, viscosity, density, solids, fouling, corrosion, and phase-change behavior.
Pressure Requirements
Define design pressure, operating pressure, allowable pressure drop, and relief conditions.
Material and Cleanliness
Identify corrosion resistance, contamination limits, sanitary needs, and gasket compatibility.
Cleaning and Access
Clarify CIP, mechanical cleaning, inspection, disassembly, downtime, and maintenance intervals.
Mechanical and Code Needs
Include footprint, orientation, connections, supports, vibration, code stamping, and documentation.
Selection Workflow
A practical path from application data to purchase.
Define the thermal duty
Establish heat load, temperatures, flow rates, operating range, and required approach temperature.
Characterize both fluid streams
Document pressure, viscosity, solids, fouling, corrosion, contamination, and phase behavior.
Choose the exchanger type
Match shell-and-tube, plate, air-cooled, or specialty designs to service and maintenance.
Verify pressure drop and cleaning
Balance compactness and heat transfer against pumping cost, fouling, and service access.
Review mechanical design and support
Confirm materials, code, testing, documentation, replacement parts, and lifecycle service.
