Used Plate Heat Exchangers for Sale — What We Carry

SIGMA Process Equipment stocks a range of used plate heat exchangers covering the configurations most frequently requested by chemical processors, dairy and food manufacturers, pharmaceutical producers, and utilities. Inventory changes regularly; submit an RFQ with your duty conditions to get current availability.

Gasketed Plate-and-Frame Heat Exchangers

The used plate and frame heat exchanger is the standard choice for liquid-liquid heat recovery where compactness and easy cleaning matter. Corrugated plate packs deliver turbulent flow at low velocities, resulting in high heat-transfer coefficients relative to surface area. Used plate and frame heat exchangers for sale in our stock cover a range of plate counts and frame sizes. Common brands include Alfa Laval, GEA, APV, and Tranter — ask in your RFQ if you need a specific make for spare-part compatibility.

Typical plate materials: used heat exchangers stainless steel (SS 316L) for most chemical and food-grade duty; titanium for sea water heat exchanger applications or chloride-bearing streams.

Wide Gap Plate Heat Exchangers

A wide gap plate heat exchanger uses wider plate spacing and a modified flow channel to handle viscous liquids, fibrous media, and feeds carrying suspended solids that would block standard plate spacing. Applications include pulp and paper, starch processing, sugar refinery, and waste heat recovery from particle-laden streams. Available in SS 316L and titanium.

Spiral Heat Exchangers

Used spiral heat exchangers for sale handle difficult fouling duties — both channels have a single continuous flow path, so there are no dead zones and fouling deposits tend to self-clean under turbulence. Well-suited to viscous liquids, slurries, and condenser duty in solvent recovery systems. Contact us with your operating conditions for current availability.

General Used Heat Exchanger Stock

Beyond these specific types, we carry a broad pool of used heat exchangers for sale — including surplus heat exchangers from plant decommissioning and second hand heat exchangers for sale from process upgrades. These units often represent excellent value relative to new equipment. All carry documented inspection records. For applications where industrial heat exchanger cost is a key constraint, used surplus equipment typically delivers 40–70% savings over new.

Falling Film and Scraped-Surface Types

We also stock used scraped surface heat exchangers for high-viscosity or crystallising duties, and falling film heat exchangers commonly used in evaporation pre-heating and solvent recovery. Specify the duty and we will advise on available units.

Key Buying Considerations

• Duty data — hot-side and cold-side flow rates (m³/h), inlet/outlet temperatures, and operating pressures are needed to size the unit correctly.
• Plate material — SS 316L for standard chemical and food duty; titanium for seawater or chloride service; Hastelloy for highly corrosive streams.
• Gasket material — NBR, EPDM, or Viton depending on fluid compatibility and temperature range.
• Frame size — check that the plate count can be increased if heat load grows (gasketed PHEs are easily extended by adding plates).
• Industrial heat exchanger types — if space or fouling constraints rule out a plate unit, see our used shell and tube heat exchangers for the alternative.
