Industrial Water Testing and Legionella Management
Prochem provides water sampling, on-site testing and laboratory testing coordination for cooling towers, chillers, closed loops and boilers. We help commercial and industrial customers across New Zealand understand water quality, manage corrosion and scale, and plan appropriate treatment. Legionella sampling and risk management support are provided where relevant to the water system.
Sampling, Analysis and Practical Advice
We assess your water system, collect samples and carry out appropriate on-site checks. Where laboratory analysis is needed, we arrange testing through third-party laboratories with the relevant IANZ accreditation. Prochem reviews the findings alongside system conditions and provides practical treatment recommendations and service reports.
Routine water chemistry testing and Legionella testing address different questions. Your programme is matched to the equipment, operating conditions and risks at your site.
Testing for Your Water System
Testing helps identify changes in water chemistry and system condition. We select the checks and reporting needed for your chiller, closed loop or boiler programme.

Ongoing sampling helps us review the programme as conditions change. Explore our custom chemical formulation service.
Water Testing and Legionella FAQs
How does Prochem support Legionella risk management?
We provide risk assessments, sampling and control-plan reviews for cooling towers and relevant building water systems. We help interpret laboratory results and coordinate appropriate corrective actions and follow-up testing based on the findings and the site’s management programme.
How is the water sampling schedule decided?
The schedule depends on the system, operating conditions, site control plan and applicable requirements. Water chemistry checks and microbiological laboratory analysis may follow different schedules. We help agree a programme suited to your equipment and risks.
What can a cooling tower service visit include?
A visit can include water sampling, chemistry checks, review of biocide and inhibitor dosing, corrosion and scale monitoring, and cleaning recommendations. The agreed scope determines the checks completed and the follow-up advice provided.
What reports and records are provided?
Depending on the agreed service, you receive service reports, relevant laboratory results, treatment recommendations and monitoring records. These records support ongoing water management and can assist building warrant of fitness inspections and other compliance reviews where applicable.
