With the global phasedown of HFCs, $\text{CO}_2$ (R744) has become the leading natural refrigerant for sustainable cooling. However, its high operating pressures demand exceptional thermal and mechanical integrity. Sail design and manufactures heavy-duty $\text{CO}_2$ gas coolers and evaporators engineered to withstand transcritical and subcritical cycle demands, ensuring optimal heat transfer and zero-leakage safety.H2: Transcritical Gas Coolers & Subcritical Evaporators

Q: Why do you use K65 copper tubes for $\text{CO}_2$ heat exchangers?
A: K65 is a high-strength copper-iron alloy that allows for thinner tube walls while safely handling the high working pressures (up to 120 Bar) of transcritical R744 systems, ensuring high thermal efficiency without adding extra weight.
Q: Do you provide software-calculated performance data before manufacturing?
A: Yes, we use advanced thermodynamic selection software to simulate and provide complete data sheets, including air pressure drop, fluid velocity, capacity (kW), and circuit layout for your specific R744 system design.
Our Advantages
- We have customized products for many customers, following are some projects we did before.
- We can provide designing data and production drawings.
- We promise we use the design software sold by a well-known European HAVC software company. Through 8 years of cooperation with them, we have designed, processed and exported dry coolers to various countries all around the world.
- All of customers feedback is that the actual cooling performance is almost the same as the theoretical design value.
Packaging & Shipping
The normal package is wooden box. If export to european countries, the wooden box will be fumigated. If container is too tighter, we will use pe film for packing or pack it according to customers special request.
