Engineering Copper Fin Booster Coils for High-Efficiency HVAC Reheat & Cooling
Custom Evaporator & Condenser Coils: Optimized for Chiller and Freezer Performance
We manufacture Copper Fin Booster Coils and Refrigeration Cooling Coils for demanding HVAC environments. Unlike standard aluminum fins, our all-copper design provides superior corrosion resistance and antimicrobial properties, making them ideal for hospital AHUs, marine chillers, and industrial freezers.
Advantages of Evaporator Coil Heat Exchanger
- Copper Fins: Solid copper fins offer superior thermal conductivity and natural antimicrobial protection.
- Booster Function: Designed as reheat coils in AHU systems to control humidity and air temperature.
- Corrosion Proof: All-copper construction eliminates galvanic corrosion, extending life in coastal areas.
- Heavy Duty: Thicker fin gauge (0.15mm+) withstands high-pressure cleaning without bending.
- Exact Fit: Custom dimensions and casing options ensure seamless replacement of Trane/Carrier coils.
- High Efficiency: "Copper-on-Copper" bond minimizes thermal resistance for maximum heat transfer.
- Pressure Tested: 100% Nitrogen leak testing at 3.0 MPa guarantees safety in high-pressure loops.

Details of Materials
| Material |
Key Properties |
Typical Applications & Standards |
| Carbon Steel |
High mechanical strength, cost-effective |
Widely adopted for shells in industrial systems (e.g., ASME SA-516 Gr. 70), suitable for non-corrosive environments and moderate temperatures (<300°C). |
| Stainless Steel |
Excellent corrosion resistance (e.g., SS304/316), good thermal performance |
Ideal for chemical, food processing, and HVAC systems (ASTM A240), resistant to chloride-containing fluids (e.g., < 1000 ppm Cl⁻). |
| Nickel Alloys |
Superior resistance to extreme corrosion (e.g., Inconel 600/625, Hastelloy C-276) |
Selected for high-temperature (>800°C) or aggressive environments (e.g., sulfuric acid, seawater desalination), compliant with NACE MR0175/ISO 15156. |
| Copper Alloys |
High thermal conductivity (e.g., CuNi 70/30, Brass) |
Common in condensers and cooling systems with non-corrosive water (ASTM B111), limited to < 150°C and non-ammonia environments. |
| Titanium |
Exceptional corrosion resistance (e.g., Grade 2/Grade 7) |
Critical for seawater applications (e.g., marine, offshore platforms), resistant to chlorides, acids, and biofouling (ASTM B338 Gr.2). |
Component Details

- Standard tubes are 5/8", 1/2", 5/8", 20, 1" OD.
- 304, 316 stainless steel, copper, titanium, hot dip galvanized steel or aluminum.
- Tubes are arranged inline in the direction of airflow for maximum heat transfer with minimum air side pressure drop.
Main Part - Fin
- Standard fin material is aluminum, copper, stainless steel, titanium.
- Fins are die-formed into a corrugated (waffle) configuration to encourage turbulent airflow and improve heat transfer efficiency.
- Fins do have varied types of space.
Main Part - Plate & Frame
- Standard cabinet/casing material is corrosion resistant galvanized steel.
- We also supply aluminum, stainless steel cabinet and casing.
Engineering Design
We exclusively utilize HTRI and EDR design software from a renowned European software provider.
With 18 years of strategic partnership, we have successfully designed, manufactured, and exported heat exchangers to over 50 countries worldwide.
Customer feedback consistently confirms that actual cooling performance aligns precisely with theoretical design values.
We can provide detailed drawing after your order. We can also provide Custom services.
All heat exchangers undergo a rigorous pressure test: each unit is tested twice at 2.5 MPa and must hold the pressure for at least 15 minutes to verify pressure resistance and ensure no leakage.
