CHRS Fluid™ HEAT – Eco‑Safe Thermal Transfer for Closed‑Loop Systems
(CHRS, GSHP, District Heating, Industrial Loops)
Eco‑Safe: 100% biodegradable, non‑toxic, plant-based 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 CHRS Fluid™ HEAT vs Glycol
Lower viscosity → less pumping energy, higher real‑world COP.
Maintains stable output.
CHRS Fluid™ HEAT Standard operating range: −2 °C to 80 °C (continuous), to 90 °C (short excursions).
Glycol typically operates -20°C to 60°C before oxidation and viscosity issues
| Metric | CHRS Fluid™ HEAT | Standard Glycol |
| Coefficient of Performance | +5 – 12% | Baseline |
| Freeze Point Protection | -5℃ | -20℃ |
| Boil Point Protection | >100℃ | Similar |
| Corrosion Resistant | Excellent | Good |
| Hazard Classification | Non-Hazardous | Hazardous |
| Biodegradability | Fully Biodegradable | Not Biodegradable |
| Operational Life | 8-12 | 3-7 |
| Net Zero/ESG Compliant | Yes – 100% | No |
Thermal Conductivity
Glycol- Water mix will hit ~0.38 to 0.45 W/m.k
CHRS Fluid™ HEAT will realistically sit at ~0.45 to 0.55 W/m.k
The only advantage Glycol has – in a controlled test environment
Specific Heat: CHRS Fluid™ HEAT 3.8 – 4.1 J/g.K vs Glycol ~3.2 – 3.6 J/g.K
Maintenance
8–12 year service life in a sealed loop (vs 3–7 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™ HEAT Wins in Real World
Lower Viscosity – lower pump energy = higher system COP
Better Heat Retention – less temperature drop over distance
Longevity – CHRS Fluid™ HEAT lasts 8 – 12 years vs Glycol’s 3 – 7 before pH crash/oxidation
Maintenance Cost – CHRS Fluid™ HEAT has no hazardous disposal, no corrosion inhibitor
Environmental Compliance – CHRS Fluid™ HEAT is biodegradable, Glycol is hazardous
Public Procurement – CHRS Fluid™ HEAT 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™ HEAT beats it everywhere except the bench test, and the bench test doesn’t pay the bills.
