Surplus heat exchanger spare parts are worth real money, and we buy them. Plate packs for plate-and-frame exchangers, spare tube bundles, replacement gaskets (especially for discontinued models), channel covers, floating heads, baffles, and any other heat exchanger components sitting in your warehouse have active demand in the secondary market. Surplus Heat Exchangers purchases parts inventory of any size — from a single spare tube bundle to an entire warehouse of plate exchanger components.
Surplus Heat Exchangers buys used and surplus heat exchangers nationwide — 100% upfront, with free rigging and freight, in any condition. Send a photo of the nameplate to 951-403-5738 for a same-day cash offer.
Why Spare Parts Have Surprising Value
Many facilities accumulate heat exchanger spare parts over decades of operation. Spare tube bundles purchased for planned retubing that never happened. Plate packs ordered for expansion projects that were cancelled. Gasket sets bought in bulk that outlasted the exchanger they were meant for. Channel covers and floating heads kept as emergency spares that were never needed.
This inventory represents frozen capital — money spent years ago that is generating zero return while occupying valuable warehouse space. The good news is that these parts have active demand in the secondary market. Other facilities running the same equipment need these exact components, and buying used or surplus parts saves them 40–70% compared to ordering new from the OEM (if the OEM even still makes them).
At Surplus Heat Exchangers, we buy this inventory and match it to buyers who need it. You convert dead warehouse stock into cash, free up storage space, and eliminate the carrying cost of inventory you will never use. The buyer gets the part they need at a fraction of new cost with immediate availability instead of 8–16 week OEM lead times.
Types of Spare Parts We Purchase
Plate Heat Exchanger Plates and Gaskets
Plate-and-frame heat exchangers (Alfa Laval, APV/SPX, GEA, Tranter, SWEP, Sondex) use removable plates and gaskets that are replaced periodically. Surplus plates and gaskets for these exchangers are among the most actively traded spare parts in the heat exchanger market.
We buy individual plates, complete plate packs, and gasket sets for all major brands and models. Plates made from stainless steel (304, 316), titanium, Hastelloy, or nickel alloys are particularly valuable. Even plates with minor gasket groove wear or light scaling are sellable — they can be reconditioned (cleaned, regasketed) and returned to service.
Gaskets for discontinued plate exchanger models are especially valuable because the OEM no longer manufactures them. If you have gaskets for older Alfa Laval, APV, or Tranter models that have been superseded, those gaskets may be worth significantly more than you expect because the only alternative for the current operator is a complete exchanger replacement.
Spare Tube Bundles
A spare tube bundle is one of the most valuable individual components you can sell. New tube bundles cost $15,000–$200,000+ depending on size, material, and tube count. A surplus spare bundle — never installed, or pulled and stored in good condition — commands 40–70% of new price in the secondary market.
We buy tube bundles made from any material: carbon steel, stainless steel (304, 316, 321, 347), copper, cupro-nickel, admiralty brass, titanium, Hastelloy, Inconel, and Monel. The tube material is the primary value driver, followed by the bundle dimensions and condition.
Channel Covers, Floating Heads, and Bonnets
These precision-machined components are expensive to manufacture new — a large floating head assembly can cost $20,000–$80,000+ from the OEM. Surplus spares in good condition sell readily in the secondary market to facilities that need replacements during turnarounds.
Tubesheets
Spare tubesheets, particularly those made from clad materials (carbon steel with stainless, titanium, or nickel alloy cladding) or solid exotic alloys, have high value. A titanium-clad tubesheet for a large exchanger can be worth $30,000–$100,000+ as a spare component.
Expansion Joints and Bellows
Metallic expansion joints and bellows assemblies for heat exchangers are precision components with significant value. Stainless steel and Inconel bellows are particularly sought after.

Plate Heat Exchanger Parts: The Biggest Opportunity
Plate-and-frame heat exchangers have the most active spare parts market because they are designed for periodic plate and gasket replacement. Every facility running plate exchangers accumulates surplus plates over time — from capacity changes, model upgrades, or over-ordering. Here is why these parts are particularly valuable:
Model discontinuation: Plate exchanger manufacturers regularly discontinue older models and replace them with new designs. When this happens, the only source of replacement plates for the thousands of older units still in service is the secondary market. If you have plates for a discontinued Alfa Laval M10, APV SR2, or Tranter GX-26, those plates may be worth 2–3× their original purchase price because of scarcity.
Long lead times: New plates from OEMs typically have 6–12 week lead times. A facility with an unplanned plate failure needs replacement immediately — they cannot wait months. Secondary market availability at a premium price is still cheaper than the production losses from extended downtime.
Titanium plates: Titanium plate packs are among the most valuable heat exchanger components per pound. A complete titanium plate pack for a large frame (Alfa Laval M15, TL10, or equivalent) can be worth $30,000–$80,000+ depending on plate count and condition.
How to Inventory Your Spare Parts for Sale
To get the best offer on your spare parts inventory, provide us with:
- Manufacturer and model: For plate exchangers, the frame model (e.g., Alfa Laval M10-BFG, APV N35, Tranter GX-51). For tube bundles, the exchanger manufacturer and serial number.
- Quantity: Number of plates, gaskets, or components available.
- Material: Plate material (304 SS, 316 SS, titanium, Hastelloy) and gasket material (NBR, EPDM, Viton).
- Condition: New/unused, used but serviceable, or damaged. For plates, note any visible wear, scaling, or gasket groove erosion.
- Storage conditions: Indoor warehouse (ideal) vs. outdoor (acceptable for metal parts; gaskets should be indoor).
If you have a large inventory and do not want to catalog it yourself, we can arrange a site visit to inventory and value the parts on-site. For large lots, this is often the most efficient approach.
