Titanium Evaporator (Titanium Coil/Titanium Barrel)

Pure Titanium Heat Exchange for the Toughest Fluids

Delin titanium evaporators — also known as titanium coils or titanium barrels — are built from pure titanium TA1/TA2 (Grade 1/2). Titanium is completely immune to corrosion in seawater, brine, and aggressive chemical media, which is why it is the material of choice for seafood machines, heat pump water heaters, swimming pool heat exchangers, and chemical processing equipment.

Built Tube by Tube

Each coil is TIG welded from titanium tube in our own workshop — a process we have refined through years of manufacturing. Every weld is argon-shielded and every finished unit is pressure-tested before it leaves the factory, so you receive a coil that holds tight under years of thermal cycling.

Why Seawater and Chemicals Demand Titanium

Copper, brass, and ordinary stainless steel corrode or pit when exposed to seawater, brine, and many industrial chemicals. Pure titanium — TA1/TA2 — forms a stable oxide film that resists pitting, crevice corrosion, and stress corrosion cracking in these environments, which is why it is specified for seafood constant temperature machines, heat pump water heaters, swimming pool heat exchangers, and marine HVAC systems. Because titanium never leaches metal ions into the fluid, it is also safe for potable and aquaculture water.

Sizing a Titanium Coil for Your System

Delin supplies titanium coils and barrels matching systems from 2 HP to 30 HP, with tube diameters from Φ9.52 mm to Φ19.05 mm. Coil diameter, length, tube count, and connection type — thread, flange, or copper flare — are set to your tank dimensions and cooling load, and design pressure can be raised from the standard 1.0 MPa to 1.6 MPa for higher-duty systems. Send us your heat load, tank geometry, and inlet water conditions, and our engineers will calculate the required surface area and recommend a coil configuration rather than a guess.

Specifications You Can Customize

• Tube diameter Φ9.52 mm – Φ19.05 mm
• Design pressure ≤ 1.0 MPa, customizable to 1.6 MPa
• Design temperature -20°C to +120°C
• Connection: thread, flange, or copper flare
• Standard sizes match 2 HP – 30 HP systems; OEM sizes and configurations available

Proven in Marine and Chemical Duty

Titanium evaporators from Delin cool and heat in applications where alternative materials fail quickly: seafood constant temperature machines keep marine product at temperature in salt water, heat pump and swimming pool systems transfer heat in chlorinated and treated water, and chemical processing equipment moves aggressive media without corrosion. For each duty we confirm the right titanium grade, wall thickness, and weld schedule before production, and pressure-test every finished coil.

What You Get When You Buy Direct

Because Delin fabricates in-house, you are buying from the workshop floor rather than through a trading company. That means documented material certificates for your titanium grade, weld records you can audit, a coil built to your tank geometry instead of adapted from stock, and factory-direct pricing. We can also produce an OEM prototype first, so you validate the fit and performance of the coil before committing to a production run.

Quality You Can Verify

Our titanium evaporators are manufactured under ISO 9001 and are available for SGS third-party inspection. Because we fabricate in-house, we can match your existing coil geometry, tank dimensions, or new system design — and deliver a documented, tested component rather than a generic import.
