Frequently Asked Questions

Installation of Maxwell™

Yes, Maxwell™ is engineered and formulated to provide increased heat transfer in closed-loop hydronic systems containing water, water / propylene glycol and water / ethylene glycol.

Maxwell™ is delivered to site in a concentrated solution (15% conc.) which is then diluted (to 2% conc. in the system fluid) during the installation process. ~25L of Maxwell™ (at 2% conc.) is needed per ton of cooling for HVAC applications.

Yes, the system does not have to be shut down. Maxwell™ can be added to an operating system while the same volume is drained from the system itself.

This will depend on system volume and site logistics but typically, 4 to 8 working hours are required for an installation.

Operation & Maintenance for Maxwell™

No, Maxwell™ has been tested to ASTM Standards for corrosion and erosion of materials commonly used for pipes, gaskets, seals, valves and fittings.

No, the aluminum oxide nanoparticles in Maxwell™ are <600 nm and easily pass through the typical system filters and strainers used in hydronic systems.

HTMS recommends that the system fluid have a pH ≥10 for optimum performance. HTMS also recommends replacing existing pump seals with an EPR / Silicon Carbide (Sic) seal.

It is necessary to periodically measure pH and Density – this can be done autonomously and automatically with the Maxwell™ Monitoring and Maintenance System. Also, HTMS offers an Owner’s Service and Maintenance contract that provides regular scheduled visits to monitor the system fluid.

Health, Safety & the Environment

Sub-micron aluminum oxide particles, dispersed in water or a water and glycol mixture. Maxwell™ is an odourless white dispersion, classified as non-hazardous according to EU Regulation EC1272/2008.

No, Maxwell™ is classified as a non-hazardous chemical. However, proper precautions must be taken when handling, which include wearing eye protection and rubber gloves.

Spill procedures are handled in the same way as for the system’s base fluid with added chemicals. Small spills may be soaked up with common absorbent materials, larger discharges should be disposed of.

Disposal of system fluid containing Maxwell™ into drains or septic systems is prohibited. Disposal must be in accordance with local regulations.
