Two ways projects reach us
Cleansol is a specialized field-services contractor for hygienic process and utility systems in the Life Sciences, Data Center, Semiconductor and Food & Beverage industries. We work with owners, engineers and mechanical contractors to plan and execute cleaning, passivation, derouging and oxygen cleaning scopes, then provide the records needed for turnover.
New construction or expansion
The system is going in now. Startup is on the schedule.
- Pre-construction planning and circuit design
- Pre-operational cleaning and flushing
- Passivation where specified
- Verification and documented turnover
Existing system or shutdown
The system is in service and something has changed.
- Condition assessment and scope definition
- Chemical cleaning or derouging as required
- Re-passivation where specified
- Verification against acceptance criteria
Services
Six services, one execution standard
Passivation
Free iron and weld contamination put new stainless systems at risk
On-site preparation, treatment, rinse, verification and documentation for stainless steel piping, tanks and equipment.
Passivation DerougingRouge in high-purity water and process systems raises quality questions
Assessment, compatible chemistry selection, removal, rinse, re-passivation and verification, planned around your shutdown.
Derouging Chemical CleaningDeposits and fabrication residue interfere with process performance
Chemistry and procedure selected for the contaminant, the metallurgy, the system configuration and your requirements.
Chemical Cleaning Oxygen & High-Purity GasOxygen service leaves no margin for residual contaminants
Cleaning, inspection and preservation for systems and equipment intended for oxygen or specified high-purity gas service.
Oxygen & High-Purity Gas Cleaning Hydronic Cleaning & FlushingConstruction debris settles wherever flushing velocity falls short
Circuit planning by pipe size, flushing and filtration, with velocity verified live by portable non-invasive meters.
Hydronic System Cleaning & Flushing Equipment Exterior CleaningCorrosive exposure and scaling degrade equipment condition over time
Planned exterior cleaning and surface restoration for process equipment, with containment and material compatibility considered.
Equipment Exterior CleaningPre-Construction
The plan exists before the trucks do
Successful field execution begins with an executable plan. Cleansol reviews drawings and specifications, defines circuits and temporary connections, calculates volumes and flow requirements, plans equipment and filtration, and aligns responsibilities, labor and schedule before mobilization.
Scope intake
P&IDs, plans, specifications, system list, pipe sizes, metallurgy, schedule and acceptance requirements.
Design review
Circuit boundaries, temporary connections, high and low points, valves, isolation and access.
Execution planning
Volumes, flow targets, chemistry, pumping, filtration, instrumentation, labor and sequence.
Turnover alignment
Required readings, samples, logs, calibrations, approvals and the customer closeout format.
Marked-up drawing
Circuits, temporary connections, valve positions and monitoring points.
Basis of estimate
Volumes, flow targets, equipment, labor and schedule assumptions.
Responsibility matrix
Scope alignment among owner, engineer, CM, mechanical contractor and Cleansol.
Data Centers
Liquid cooling brought stainless into the data hall
Technology cooling systems, CDU circuits and direct-to-chip loops increasingly run stainless piping with high-purity, low-conductivity coolant. In those systems corrosion products are unacceptable, and passivation stops being a pharma word and becomes a commissioning requirement.
Cleansol brings the same metallurgy work it has performed in regulated facilities since 2016: in-system passivation after cleaning and before fill, prefabricated skid and module cleaning at the shop or on delivery, and turnover records built to survive commissioning review.
Two Systems, Two Disciplines
Data center cooling splits into a hydronic side and a hygienic side. Hydronic flushing scopes, including glycol and specified heat-transfer-fluid filling, are delivered through Cleanhydronics. Stainless passivation and specialty cleaning scopes are delivered by Cleansol. Same crews, same documentation standard, one project.
The Guardrail
Passivation is not required on every cooling system. On a conventional carbon steel chilled water loop it is generally not applicable, and we will tell you so.

Equipment and Controlled Execution
Configured around your system, not ours
Cleansol configures modular pumping, heating, filtration and instrumentation around the requirements of each system. Key process variables can be displayed, monitored and recorded throughout execution, creating a traceable project record.
- Modular pumps, tanks, heaters, filters and hoses sized to the circuit
- Hygienic pumps, valves and instrumentation in the temporary process equipment
- Instruments repositioned as the sequence advances
- Execution coordinated with construction, shutdown and commissioning schedules
Documentation
Turnover is a package, not a promise
CLEANDOC is Cleansol's turnover documentation package. Contents follow the project scope and your closeout format, defined before execution so the record is complete when the work is.
A redacted sample index is available for review during scope development.
CLEANDOC / Sample index. Redacted
- Approved procedures and project scope
- Chemical records and safety data
- Instrument calibration records
- Operating logs and monitored variables
- Measured readings log, where in scope
- Test results and verification records
