Product Overview:
The COIL - PMW205 is a heating coil designed for use in dry interiors, offering high heat output without the need for a fan. It is suitable for environments where construction height is not a limiting factor.

Specifications:

• Total Width: 420 mm
• Construction Height: 205 mm
• Length: 900 to 3000 mm

Usage Recommendations:
This coil is recommended for individual use in dry interiors that require higher heat output.

Temperature Equation:
The heat transfer rate (Q) is calculated using the formula:
Q = µ QN (tw - tA) / 50^m
Where:

• m = temperature exponent (1.4236)
• tW = mean heating water temperature
• tA = mean air temperature in the interior [ºC]
• QN = nominal heat transfer rate for a temperature difference of 50 ºC [W]
• µ = flow value coefficient (µ=1 for nominal flow values)

Heat Transfer Rate Data:
The document provides detailed tables showing the heat transfer rate (Q) for various lengths (900 mm to 3000 mm) and mean water temperatures (tW) at different mean air temperatures (tA) of 15, 20, and 22 ºC. The heat transfer rate increases with both the length of the coil and the mean water temperature.

Key Observations:

• Higher mean water temperatures and longer coil lengths result in higher heat transfer rates.
• The coil is effective in environments where high heat output is necessary without the use of a fan.
