Industries
Specialized mechanical engineering and hydronic flushing solutions across mission critical sectors.
Data
Data centres run continuously, and a fouled chilled water circuit shows up as rising approach temperatures long before it shows up as a failure. We deliver BG29 pre commission cleaning and ongoing chemistry programmes for hyperscale and colocation facilities, working around live load and handing over with documented particulate counts and chemistry sign off.
Industrial
New build and refurbished plant rooms, central utility plants and process cooling across manufacturing and commercial estates. We flush, clean and commission closed systems to BSRIA standards, then establish the treatment regime that keeps heat transfer efficiency where the design intended it.
Oil & Gas
Hydrocarbon and utility systems where contamination, corrosion and unplanned downtime carry the highest cost. We provide pipeline flushing, dewatering, nitrogen inerting and pressure testing, alongside PSV recertification and flange management during shutdowns and turnarounds.
Medical
Hospitals, clinics and research laboratories where hydronic system reliability is both a patient safety matter and a compliance one. We clean and commission heating and cooling systems to specification, maintain water chemistry, and work within the access and infection control constraints of a live healthcare estate.

Frequently Asked Questions
BG29 pre commission cleaning is a standard hydronic flushing methodology specified by BSRIA to prepare closed loop water systems (like LTHW and chilled water) for operation. It removes millscale, jointing debris, and biological contaminants to prevent corrosion, system blockages, and component failures.
Yes, all of our pipeline flushing, chemical conditioning, and commissioning procedures strictly adhere to European BSRIA guidelines and ASHRAE specifications. We provide audit ready compliance certificates for every project upon completion.
Geothermal purging is the process of removing all trapped air pockets from ground source heat pump loop arrays. We then introduce and balance specialized glycol based antifreeze solutions to ensure optimal heat transfer performance and freeze protection.
We specialize in mission critical infrastructure sectors including hyperscale data centres, sterile pharmaceutical processing plants, Grade A commercial office buildings, and oil & gas pipeline systems.
We respond to all online enquiries and tender requests within one working day. For urgent operational remediation or rapid on site troubleshooting, please call our UK or Ireland hubs directly to coordinate mobilization.
