Every stage, from scope to turnover
Each service answers four questions: what we do, when we become involved, what we bring to the site, and what the contractor receives. Work is planned and executed to the approved project specifications, system requirements, equipment limitations and the water-treatment specialist's approved treatment plan.
Pre-Construction Planning
Drawing and specification review; take-off review when available; system volume assumptions; flow and equipment planning; chemistry and waste estimates; budget scope; preliminary schedule. Estimators get a defensible flushing allowance; project managers get an execution plan before the first hose arrives on site.
Precommissioning Flushing
Flush-zone planning; temporary pumping sized by hydraulic calculation; filtration; branch and riser sequencing; strainer monitoring; debris removal; and measured flow verification at multiple points across different pipe sizes simultaneously. Pressure testing support where included in the scope.
Chemical Cleaning
A defined cleaning process with its own procedure: project-specific chemistry based on system materials and contaminants; chemical circulation and control; rinsing and neutralization; acceptance checks; and wastewater and disposal planning. Chemical cleaning removes construction residues, oils, flux, corrosion products, scale and other deposits from system surfaces.
Water Treatment Services
Water treatment conditions and protects the system water after cleaning or filling, so the required water-quality baseline can be established. It is delivered jointly with a qualified water-treatment specialist, and each party's scope stays clear:
Specialist scope
System-water review, chemical selection and supply, concentration targets, test methods and acceptance criteria — from the contractor's, owner's, engineer's, or commissioning team's selected water-treatment provider. Our field experience includes coordination with nationally recognized providers such as Chem-Aqua and Nalco Water, an Ecolab company, as well as regional and project-specific treatment specialists; Cleanhydronics executes their approved plan in the field and keeps chemistry decisions in their lane.
Cleanhydronics scope
Temporary equipment, on-site chemical receiving and handling, dosing, circulation, sampling support, field readings, and the execution and turnover records.
Chemical cleaning and water treatment are often recommended on the same project, but each keeps a separate scope, price and set of deliverables. Third-party company names are provided solely to describe project-coordination experience. No endorsement, sponsorship, or corporate affiliation is implied.
Glycol & Heat-Transfer Fluid Filling
Some hyperscale and AI data center specifications require the loop to be flushed, chemically cleaned, and then charged with a glycol solution or a manufacturer-specified heat-transfer fluid such as a DOWTHERM or THERMINOL product instead of treated water. We plan the fill during preconstruction, receive and stage the fluid with lot and batch traceability, transfer and charge to the manufacturer's procedure, circulate, verify concentration at multiple points, and hand over the record. Fluid selection stays with the engineer, the equipment manufacturer and the fluid manufacturer; Cleanhydronics executes the specified fill as one sequence with the flush.
Potable-Water Disinfection
Approved disinfection procedure; concentration and contact-time controls; sampling coordination; results and records — meeting the regulatory requirements that apply to the project.
Disinfection applies to potable and domestic water systems. Closed-loop hydronic systems are flushed, cleaned and treated, then filled with water, glycol or the specified heat-transfer fluid; they are not disinfected.
Closeout Documentation
The approved method, field logs, flow and condition records, water-test results, exceptions and completion report as included in scope — organized for the commissioning agent, engineer and owner. The flush isn't finished until the paperwork proves it.
