🌡️ Coil Types
CTAPRO supports 6 coil types for heating, cooling, and energy recovery applications.
| Coil | Function | Media |
|---|---|---|
| Heating Coil | Air heating | Hot water / steam |
| Cooling Coil | Cooling & dehumidification | Chilled water |
| Electrical Coil | Electric heating | Electrical resistance |
| Condenser Coil | Heat rejection | Refrigerant / steam |
| Expansion Coil (DX) | DX cooling | Refrigerant |
| Recovery Coil | Energy recovery | Air-to-air dual circuit |

Connection Types
Flat Copper, Flat Fe, Fe Threaded, Brass Threaded
Finishing Options
Standard: No extra finishing (default)
Premium: BlyGold Polual XT — recommended for coastal installations and corrosive environments.
Calculation Modes
Certified Performance, Standard, Reduced Tolerance
💡 Tip
BlyGold coating is essential for coastal cities (Tel Aviv, Haifa, Eilat) where salt air corrodes standard copper fins within 2-3 years.
💧 Fluid & Refrigerant Specs
Water/Steam
Entering/Leaving temperature: 0–100°C. Max pressure drop: 0–100 kPa. Specialty fluid: ESSOTHERM 500.
Refrigerants (Condenser Coil — 13 types)
| Refrigerant | Type | Refrigerant | Type |
|---|---|---|---|
| R22 | HCFC (legacy) | R448A | HFO blend |
| R407C | HFC blend | R449A | HFO blend |
| R410A | HFC blend (standard) | R452A | HFO blend |
| R507A | HFC blend | R513A | HFO blend |
| R404A | HFC blend | R32 | HFC (low GWP) |
| R407F | HFC blend | Steam | Direct steam |
| R134A | HFC |
💡 Tip
R410A is the current industry standard in Israel. R32 and HFO blends (R448A, R449A) are the future — lower GWP.
