As global industries push toward decarbonization, the
CO₂ transcritical high-temperature heat pump
has emerged as a cleaner, safer, and more efficient alternative to coal-fired and gas-fired boilers—especially in applications requiring
90°C to 135°C high-grade heat.
More and more manufacturers are replacing fossil-fuel boilers with CO₂ heat pump systems to reduce energy consumption and achieve sustainable development goals.
Zhenmingzhu, a specialist in industrial high-temperature heat pump and waste-heat recovery Solutions, is leading this technological shift.

Why the CO₂ Transcritical High-Temperature Heat Pump Is a Breakthrough Technology
CO₂ (R744) is a natural refrigerant with a Global Warming Potential (GWP) of just 1, making it one of the most eco-friendly alternatives available.
The transcritical CO₂ cycle enables the system to achieve high operating pressures and efficient heating performance.
- High outlet temperature range: 90°C–135°C
- Stable and reliable continuous heating
- Zero SO₂ / NOx emissions
- Long operational lifetime and minimal maintenance
- Excellent thermodynamic efficiency
Application Case: Food Canning Production Line
Background
A food canning plant depended on a 4-ton coal-fired boiler to supply hot water and steam (95°C–125°C) for sterilization and production.
However, the system suffered from the following issues:
- High coal consumption and unstable heat output
- High CO₂, SO₂, and particulate emissions
- Frequent maintenance and downtime
- Non-compliance with new environmental regulations
Zhenmingzhu CO₂ Heat Pump Solution

CO₂ Heat Pumps vs. Traditional Boilers
1. Energy Efficiency
- Coal boilers: ≤70% efficiency
- Gas boilers: 80–92% efficiency
- CO₂ heat pumps: COP 3.5–4.8
2. Environmental Impact
| Technology | Emissions | Compliance |
|---|---|---|
| Coal Boilers | Very High | Poor |
| Gas Boilers | Medium | Moderate |
| CO₂ Heat Pumps | Near-zero | Excellent |
3. Operating Cost
Since heat pumps extract renewable heat from the air or waste sources, operational costs remain significantly lower than fossil-fuel boilers.
