Cooling transfer fluid that makes any chilled water or HVAC system measurably more efficient. UK-tested, non-corrosive, and installed with zero downtime.


Up to a 22% reduction in cooling costs — measured across UK field sites.
Chiller reaches target temperature quicker, so plant works less and lasts longer.
Chiller runs more efficiently, improving COP with no plant change.
Equipment short-cycles less and operates within a healthier duty band.
Every unused kWh saves ~0.18 kg CO₂ — no capital project required.
Compatible with scroll, screw, centrifugal and absorption chillers.
Chilled water systems rely on water as the cooling medium because it's cheap and abundant — but water isn't actually a great conductor of thermal energy. It needs more electricity to move the same amount of heat away from your space.
Inject-a-Cool transfers thermal energy significantly faster and more effectively, reducing overall system runtime without affecting cooling performance. Less electricity delivers the same cooling — straight to your bottom line.

18%
Average electricity reduction across a 14-site UK field trial (max 22%)
0%
Increase in corrosion on steel, copper or aluminium in lab testing
6+
Years projected active lifespan in a sealed system
Laboratory thermal-stability testing confirms Inject-a-Cool is active from −20°C to 120°C and shows no increase in corrosion on common system metals.
Hospital campus
Multiple chillers serving wards and data rooms — energy cut by 16–20% year on year.
1970s office block
Fan-coil chilled water HVAC — measured 18% electricity saving.
Data centre
Chilled water loop COP improved 10%, reducing electricity use by 15%.
Food-processing glycol loop
25 m³ chilled circuit — chiller load down 12%, line throughput up.
University district cooling
3.5 GWh annual demand — 22% electricity reduction (≈ 650 t CO₂ avoided).
Treating both heating and cooling circuits across your estate maximises savings — one supplier, one approach, year-round efficiency.

"Inject-a-Cool cut our electricity bill by almost a fifth without touching the plant room."
Nigel Mackie
Director of Cooling Contractors
"Installing Inject-a-Cool across our clients' estate generated measured savings of 19%."
Martin Watson
Chief Engineer, Facilities Management
"The properties Inject-a-Cool consists of are excellent — non-hazardous yet generating great performance."

No — it works alongside any BuildCert-approved inhibitor or glycol. Independent testing confirms full compatibility with leading inhibitors.
None. Dosed via a valve, dosing pot or pump adaptor while the system is running.
Yes — suitable for any wet system with water-to-air heat exchange. Compatible with fan coil units, AHUs, chilled beams and process loops, and with scroll, screw, centrifugal and absorption chillers.
Both. Inject-a-Cool works by increasing the thermal contact surface within the system, so it performs well regardless of system condition.
Yes. While Inject-a-Cool offers some corrosion-inhibiting properties, it's not a replacement for certified inhibitors — and it is fully compatible with leading BuildCert-approved products.
At least six years in a sealed system. Top-up only if the system is drained down.
Yes. Non-hazardous under CLP — standard PPE is sufficient.
An annual maintenance test ensures the additive continues to perform. A 10% charge covers the test, any required top-up, and a full replacement at no extra cost should the fluid ever need replacing.
Most installations pay back within a few months to under two years depending on system size, usage and operational efficiency. We provide a free system survey and payback calculation.
