Contamination within closed-circuit water systems can significantly compromise the commissioning process. Dirt, debris and other contaminants can affect test readings, prevent consistent results and cause delays through repeated testing and adjustments.

Chemical cleaning and flushing is a critical pre-commissioning procedure for closed-circuit water systems, preparing pipework and associated components for effective commissioning. HVAC Commissioning undertakes this process in accordance with the applicable BSRIA guidance, ensuring established industry practices are followed.

Regardless of the installation method or materials used, newly installed pipework systems are susceptible to contamination. Welding slag, surface debris and other installation residues can remain within the system, including in copper pipework and heat exchanger coils. A properly executed chemical cleaning and flushing process removes these contaminants, helping to ensure the system is ready for commissioning.

HVAC Commissioning can review proposed installations, recommend the appropriate cleaning procedures, components and facilities, and manage the entire pre-commissioning flushing process from initial assessment through to completion. This comprehensive approach helps minimise commissioning delays and supports the reliable operation of the completed system.

Effective pre-commissioning flushing contributes to improved system performance, reduced maintenance requirements, extended equipment service life and enhanced occupant comfort. By ensuring water systems are properly cleaned before commissioning begins, HVAC Commissioning helps deliver efficient, reliable and cost-effective buildings.
