COIL – PMW90

Product catalog summary

Product Overview:
The COIL – PMW90 is a heating coil designed for use in dry interiors with medium heat demands. It is characterized by its high heat output without the need for a fan and a compact construction height of only 90 mm.

Specifications:

Total width: 420 mm
Construction height: 90 mm
Length: 900 to 3000 mm

Usage Recommendations:
The coil is recommended for individual use in environments where the construction height is not a limiting factor.

Temperature Equation:
The heat transfer rate (Q) is calculated using the formula: Q = µ QN (tw - tA) / 50^m, where m is the temperature exponent (1.3577), tW is the mean heating water temperature, tA is the mean air temperature in the interior, and QN is the nominal heat transfer rate for a temperature difference of 50 ºC.

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 (50 ºC to 90 ºC) at different mean air temperatures (15 ºC, 20 ºC, 22 ºC). For example, at a length of 1000 mm and a mean water temperature of 90 ºC, the heat transfer rates are 608 W, 554 W, and 532 W for air temperatures of 15 ºC, 20 ºC, and 22 ºC, respectively.
