CHRS Fluid – Eco‑Safe Thermal Transfer for Closed‑Loop Systems
(CHRS, GSHP, District Heating, Industrial Loops)
Eco‑Safe: 100% biodegradable, non‑toxic, plant/cosmetic‑grade ingredients.
A leak is not an environmental incident, no hazardous reporting, no clean‑up costs.
Matches 80–90% thermal conductivity of glycol, outperforms in pumping efficiency, stability, and life‑cycle cost.
Key Advantages & Performance vs Glycol (Synthetic)
Lower viscosity → less pumping energy, higher real‑world COP.
Maintains stable output.
Standard operating range: −2 °C to 80 °C (continuous), −5 °C to 90 °C (short excursions).
Cold‑climate tweak increases low‑temperature tolerance to −10 °C.
High‑temp tweak maintains stability at 95 °C continuous for industrial loops.
Glycol typically operates -5°C to 60°C before oxidation and viscosity issues
Thermal Conductivity
Glycol- Water mix will hit ~0.52 to 0.55 W/m.k
CHRS Fluid will realistically sit at ~0.45 to 0.48 W/m.k
The only advantage Glycol has – in a controlled test environment
Maintenance
10–15 year service life in a sealed loop (vs 5–10 years for synthetic glycol).
Self‑protecting formula (antioxidants, corrosion inhibitors, biofilm suppressants).
No hazardous disposal or special handling.
End‑of‑Life
100% biodegradable and non‑hazardous, can be discharged to the sewer after dilution.
No glycol disposal fees, no COSHH incident classification.
Low environmental footprint, strong ESG compliance.
Where CHRS Fluid Wins in Real World
Lower Viscosity – lower pump energy = higher system COP
Better Heat Retention – less temperature drop over distance
Longevity – CHRS lasts 10 – 15 years vs Glycol’s 5 – 10 before pH crash/oxidation
Maintenance Cost – CHRS has no hazardous disposal, no corrosion inhibitor
Environmental Compliance – CHRS is biodegradeable, Glycol is hazardous
Public Procurement – CHRS fits ESG/Net Zero funding rules; Glycol is “Greenwashed” at best
Market Applications
District heating closed loops
Ground source heat pumps
Industrial heat loops
Solar farm thermal integration
Glycol wins in one lab metric, thermal conductivity – but in the real world it loses on everything that matters: pumping energy, retention, maintenance, cost, lifespan, and environmental compliance. CHRS Fluid beats it everywhere except the bench test, and the bench test doesn’t pay the bills.
