Modular Width Configuration Formula
Width (mm) = (n° of elements − 1) × 40 + 35
Configuration Examples:
- 4 tubes: (4−1) × 40 + 35 = 155 mm width · 92 W at 400 mm
- 6 tubes: (6−1) × 40 + 35 = 235 mm width · 138 W at 400 mm
- 9 tubes: (9−1) × 40 + 35 = 355 mm width · 207 W at 400 mm
- 12 tubes: (12−1) × 40 + 35 = 475 mm width · 276 W at 400 mm
- 15 tubes: (15−1) × 40 + 35 = 595 mm width · 345 W at 400 mm
- 20 tubes: (20−1) × 40 + 35 = 795 mm width · 460 W at 400 mm
Each element = 1 vertical tube with 40 mm spacing. First tube = 35 mm offset from left edge. Fully customizable to any width requirement. Exceptional thermal output with premium Ø25 mm diameter.
LINEA Series Comparison — Single Tube Models
| Model | Tube Ø (mm) | Output at 400 mm | Width Formula |
|---|
| LINEA 14 S | 14 | 12 W/tube | (n−1)×40 + 25 |
| LINEA 22 | 22 | 20 W/tube | Custom width |
| LINEA 25 S | 25 | 23 W/tube | (n−1)×40 + 35 |
Technical Notes
- Exceptional Tube Diameter: Premium Ø25 mm tubes deliver exceptional thermal output compared to all other models in the LINEA series. Each tube is an independent element for maximum flexibility.
- Thermal Output Per Tube: Values shown are for a single Ø25 mm vertical tube at ΔT=50°C (water at 75°C, ambient at 20°C). Total output = number of tubes × single tube output.
- Fully Modular Design: Order any number of tubes to achieve desired width using the formula. Minimum 3 tubes recommended for structural stability. Professional round collectors Ø35 mm.
- Premium Spacing: 40 mm spacing between tube centers with 35 mm offset provides refined aesthetic and exceptional performance balance.
- Pressure/Temperature: Max operating pressure: 8 bar · Test pressure: 12 bar · Max temperature: 95 °C
- Finishes: Epoxy powder coating. Standard colors: White RAL 9010 and all RAL/NCS options. Custom finishes available upon request.
- Availability: Heights from 400 mm to 2400 mm. Widths customizable from 3 tubes (115 mm) to any maximum width required. Premium Ø25 mm single tube configuration.
