Shown on this page are experimental and calculated values of the acoustic pressure (noise) of MINIB convectors. The results were obtained by measuring selected representative samples of convectors at a distance of 1m from the measured object at an angle of 45° from the floor. The convectors were embedded in concrete in an acoustically hard room. When the convector is installed, e.g. in a living room furnished with furniture and carpet, the resulting noise level can be considered lower by 1 to 2 dB than the level published here due to the influence of higher noise absorption of the furnished room. In additon we note that for the purpose of comparison the noise of a personal computer in the same room was measured and found to be 40.8 dB.
From the charts shown it can be seen that at both speed 2 and speed 1 the fans meet the requirements of less than 40dB for daytime use and less than 30dB for night use in all cases. for this reason we recommend that Minib convectors are used at medium speed, speed 2. In cases where there is a requirement for very low noise levels or many convectors are used together then we recommend the use of speed 1, where the acoustic pressure is almost indistinguishable from the background noise.

Approximate air flow of MINIB convectors MINIB, m³/h

Note:
Air flow 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

Example of necessary adjustment of fittings:

Set:

Flow Q=180kg/h

Requirement:

Settinf 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 a setting of 2.5 turns.
