Experimental values for acoustic pressure levels associated with Minib convectors are shown on this page. Results are based on a sound pressure measurement taken at 1m from the outlet of the convector at an angle of 45° from the floor. The convectors were embedded in concrete in an acoustically hard room. If installed in a furnished and carpeted area it would be expected that the sound pressure levels would be 1 to 2 dB lower than those shown due to increased room absorption. For the purposes of comparison, a personal computer in the room used for the measurements gave a sound pressure level of 40.8 dB.
The results are shown individually for the different types of convector and fan diameters available. For all lengths and types of convector speed 1 & 2 give very low sound pressure levels and are suitable for both daytime and night time operation. We recommend that convectors are selected based on medium speed but for applications where noise levels must be minimised or there are a large number of units then minimum speed may be used.

Approximate air flow of MINIB convectors MINIB, m³/h

Info:
Airflow values listed in the table are valid for convector length of 1000 mm. For other lengths, multiply these unit flows by the relevant length of the convector in metres (e.g. COIL-KT at a length of 2 500mm has a flow 220 x 2.5 = 550 m³/ hour for medium speed).

Characteristics of the thermostatic head

1. Setting of the minimum temperature, opening of the thermostatic head
2. Setting of the maximum temperature, opening of the thermostatic head
3. Setting of the mean temperature, opening of the thermostatic head
4. Setting of the mean temperature, closing of the thermostatic head
5. Setting of the mean temperature. Pressure difference is 60kPa when the thermostatic head is closed

Flow diagram of control valve (Kv values)

Example of necessary adjustment of fittings:

Set:

Flow Q=180kg/h

Requirement:

Setting for differential pressure p=10 000 Pa

Solution:

Required setting is the intersection of values drawn on axes of the flow and pressure loss.
The result is the setting by 2.5 turns.
