COIL – PT300

Product catalog summary

Product Overview:
The COIL-PT300 is designed for heating dry interiors with a high heat output without the need for a fan. It is suitable for environments where the construction height is not a limiting factor.

Specifications:

Total Width: 303 mm
Construction Height: 300 mm
Length: 900 to 3000 mm

Usage Recommendations:
Recommended for individual use in dry interiors with medium heat demand.

Temperature Equation:
The heat transfer rate (Q) is calculated using the formula: Q = µ QN (mtw - tA) / 50, where:

m = temperature exponent (1.3909)
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 adjustment factor (µ=1 for nominal flow)

Heat Transfer Rates:
The document provides detailed tables of heat transfer rates for various lengths (900 mm to 3000 mm) and mean water temperatures (50ºC to 90ºC) at different mean air temperatures (15ºC, 20ºC, 22ºC).

Key Data from Tables:

For a length of 900 mm and a mean water temperature of 90ºC, the heat transfer rate ranges from 549 W to 630 W depending on the mean air temperature.
For a length of 3000 mm and a mean water temperature of 90ºC, the heat transfer rate ranges from 2,472 W to 2,833 W depending on the mean air temperature.
