COIL – NP2/4

Product catalog summary

Characteristics
The MINIB wall convector model NP2/4 is designed for heating dry environments. It features a width of 156 mm and operates without a fan, providing high heat output. The unit is equipped with a thermostatic head for temperature regulation.

Dimensions
The convector has a total width of 156 mm, a construction height of 340 mm, and is available in lengths ranging from 900 mm to 2000 mm.

Usage
The NP2/4 convector is a fast-reacting heating unit from MINIB's new design series. It features an aluminum cover available in silver, light bronze, dark bronze, or white-varnished coating. It is important to note that the decorative grille should not be loaded.

Temperature Equation and Heat Transfer Rate
The heat transfer rate (Q) is calculated based on the mean heating water temperature (tW) and mean air temperature (tA). The nominal heat transfer rate (QN) is specified for a temperature difference of 50 ºC. The document provides detailed tables showing the heat transfer rates for various lengths (900 mm to 2000 mm) and temperature conditions.

Key Data from Tables
- For a length of 900 mm and a mean air temperature of 15 ºC, the heat transfer rate at a mean water temperature of 90 ºC is 1,621 W.
- For a length of 2000 mm and a mean air temperature of 22 ºC, the heat transfer rate at a mean water temperature of 50 ºC is 1,020 W.
- The tables provide comprehensive data for different lengths and temperature settings, allowing for precise calculation of heat output based on specific conditions.
