Specifications
The COIL – PT105 is designed for use in dry interiors with lower heat demands and features a low construction height of only 105 mm. It is available in lengths ranging from 900 mm to 3000 mm and has a total width of 303 mm.

Temperature Equation
The heat transfer rate (Q) is calculated using the formula: Q = µ QN (mtw - tA) / 50, where m is the temperature exponent (1.4006), tW is the mean heating water temperature, tA is the mean air temperature in the interior, QN is the nominal heat transfer rate for a temperature difference of 50 ºC, and µ is a factor selected according to the diagram for non-nominal flow values.

Characteristics

• Suitable for heating dry interiors
• Lower heat output
• Compact construction height of 105 mm

Dimensions

• Total width: 303 mm
• Construction height: 105 mm
• Length: 900 to 3000 mm

Usage
The COIL – PT105 is intended for environments with lower heating intensity requirements and where a low construction height is advantageous.

Heat Transfer Rate Data
The document provides detailed tables showing the heat transfer rates (Q) for various lengths (900 mm to 3000 mm) and combinations of mean air temperatures (15, 20, 22 ºC) and mean water temperatures (50, 70, 80, 90 ºC). For example, at a length of 1000 mm and a mean water temperature of 90 ºC, the heat transfer rates are 424 W, 385 W, and 370 W for mean air temperatures of 15 ºC, 20 ºC, and 22 ºC, respectively.
