Heat exchangers, evaporators, crystallizers, pressure vessels, tanks, and specialty-fabricated equipment for industrial water treatment, desalination, brine concentration, and zero liquid discharge applications.
Industrial water treatment concentrates whatever the process could not use. The stream gets more saline, more scaling and more aggressive as it moves through recovery, and the equipment at the end of that chain sees conditions the front of the plant never does.
Harris Thermal fabricates the heat exchangers, evaporators, crystallizers, vessels and tanks that handle those duties — designed to the process conditions and materials your system requires, and built in our own shop in Newberg, Oregon.
Evaporators and crystallizers that take a waste stream to solids, eliminating liquid discharge where regulation, water scarcity or site constraints require it.
Thermal concentration equipment for seawater, brackish water and reject brine, in the alloys chloride service demands.
Heat exchangers, vessels and evaporation equipment for process water recovery, effluent minimisation and reuse loops.
ASME-code vessels, exchangers and tanks for contamination-sensitive process water, built to project material and documentation requirements.
A ZLD train is a sequence, not a single machine: pre-concentration, thermal evaporation, then crystallization to solids. Each stage hands a harder stream to the next, and the metallurgy usually has to change with it.
Harris Thermal fabricates the evaporators, crystallizers, condensers, exchangers and vessels those stages need, in materials matched to where in the train the equipment sits.
Our technical article works through why three distinct technologies run in sequence, what each stage actually removes, and what drives the energy cost of true ZLD.
Chloride level, temperature, concentration and oxidising conditions decide the alloy, and the answer often changes between the front and the back of the same train. Clad and explosion-bonded construction is available where a corrosion-resistant wetted surface over a structural carbon-steel backing suits the design.

Seawater is the hardest water most equipment will ever see. Harris Thermal's project history includes marine recuperators and equipment fabricated for wave-energy programs — work carried out in the alloys and construction that continuous seawater exposure demands. That experience carries directly into desalination and coastal treatment duty.
Exchangers and bundles built to existing geometry so they drop into the piping and supports already there, re-tubed where the shell is sound, or re-rated for a duty the original was not sized for.
Shell-and-tube heat exchangers, condensers, process heaters and coolers, falling-film and forced-circulation evaporators, crystallizers, brine concentration equipment, ASME Section VIII pressure vessels, separators, process and storage tanks, scrubbers, columns and cyclones. Harris Thermal fabricates the equipment that goes into a treatment or recovery system; the system itself is designed and integrated by the engineering firm or system provider responsible for it.
Yes. Zero liquid discharge and brine concentration are evaporator and crystallizer duties, and both are core Harris Thermal equipment. Falling-film and forced-circulation evaporators concentrate the stream, crystallizers take it to solids, and the associated condensers, heat exchangers and vessels are fabricated alongside them. Equipment is built to the process conditions, materials and code requirements the system designer sets.
Carbon steel, 304L and 316L stainless, duplex stainless, AL-6XN, Hastelloy, Inconel, Monel, titanium and other qualified specialty materials. Clad and explosion-bonded construction is available where a corrosion-resistant wetted surface over a structural carbon-steel backing suits the design. Selection follows the chloride level, temperature, concentration and oxidising conditions of the specific stream.
Yes. Harris Thermal fabricates ASME-code vessels, heat exchangers and tanks for high-purity and contamination-sensitive process water service, built to the material, surface-condition and documentation requirements the project specification defines.
