Benefits

There are many benefits in having Condair commission a humidity control system.

Confidence in performance

Experts verify that every component is installed correctly and operating to specification, ensuring optimal system performance.

Safety and compliance

Essential checks are made to meet health and safety standards, including water hygiene and gas safety, giving total peace of mind.

Optimised efficiency and ROI

Proper commissioning reduces energy use, improves reliability, and extends the life of equipment, saving time and money.

Expert commissioning by the manufacturer

A commissioning by Condair offers expert manufacturer validation, ensuring that the humidifier or dehumidifier functions safely, efficiently and according to design specifications. A commissioning visit includes:

Validation of the installation
Checking all connections (water, power, air, control signals, etc)
Validating the performance of the system against design specifications
Site optimisations for water quality and estimated run-time
Ensuring correct operation with the building management system
Demonstration of the system and maintenance requirements
Supply of documentation and certificates

Efficient operation from day one

Modern humidifiers and dehumidifiers are sophisticated systems that frequently require auxiliary equipment and multiple service connections. A commissioning by Condair can help identify any installation errors and ensure that the system meets its environmental control objectives from day one.

Unidentified installation issues may require multiple suppliers to return to determine the cause of a HVAC system issue. In addition to these direct costs, there may also be indirect costs associated with ineffective environmental control while the problem persists.

Condair’s expert engineers can identify and resolve installation and set-up issues that would otherwise cause on-going operational problems. They also ensure compliance with health and safety regulations, including Legionella risk assessments.

Frequently asked questions

Will the engineer connect my humidifier/dehumidifier to the services and BMS?

All services should be connected to the humidifier or dehumidifier prior to the commissioning engineer arriving on site. The commissioning engineer will be validating the installation and setting-up the unit, but will not connect it to services like water, drain and power. This should happen during the installation.

Any connections to a building management system (BMS) will need to be carried out by other specialist controls engineers.

Will the engineer fix any install issues during the commissioning visit?

If the engineer identifies minor installation problems that can be resolved quickly and safely (such as adjusting hose routing, tightening connections, or correcting wiring), these are often fixed during the commissioning visit as part of the service.

If there are significant installation faults (e.g., missing water supply, incorrect equipment positioning, or non-compliance with safety standards), the engineer will document these issues and advise the responsible party (installer or contractor) to correct them. The commissioning visit may be paused or rescheduled until the site is ready.

Do I need to do anything prior to the commissioning visit?

What do I need to do on the day of the commissioning?

Ensure all necessary security clearances, passes, and inductions are completed before the engineer arrives. If the humidifier is installed at height (over 2.5m), suitable access equipment must be available. The area around the humidifier must be clear and safe for the engineer to work. A responsible person should be present to sign-off works and parts used.

It is strongly recommended to have the controls engineer or BMS specialist on site during commissioning. This ensures that the humidifier can be fully integrated and tested with the BMS or other control systems. Many issues arise when controls are not connected or active, leading to delays and potential return visits. For complex projects, it may be beneficial to have the main contractor, AHU manufacturer or other key suppliers present to resolve any integration issues on the spot.
