CRUCIFORMS® types
Type 3
Typical application
CRUCIFORMS® Type 3 is 30mm thick with a high heat exchange surface.
ER 1682 RX Type 3 provide its best thermal performance when installed in the bottom part of the checker packing.
Flue size: 140 - 180 x 140 - 180 mm
Thickness: 30 mm
Heat exchange area: 19.9 - 13.1 m2/m3
Setting density: 951 - 625 kg/m3
| Shape | Weight |
|---|---|
| X shape: ER 1682 X3 | 22.5 kg |
| T shape: ER 1682 T3 | 17.5 kg |
| L shape: ER 1682 L3 | 12.0 kg |
Type 4
Typical application
The unique corrugated shape of CRUCIFORMS® Type 4 optimize the convection heat exchange for higher efficiency.
ER 1682 RX Type 4 is typically used in the middle part of the regenerator packings.
Flue size: 140 - 180 x 140 - 180 mm
Thickness: 30 mm
Heat exchange area: 20.8 - 13.6 m2/m3
Setting density: 970 - 657 kg/m3
| Shape | Weight |
|---|---|
| X shape: ER 1682 X4 | 23.0 kg |
| T shape: ER 1682 T3 | 17.5 kg |
| L shape: ER 1682 L3 | 12.0 kg |
Type 6
Typical application
Type 6 CRUCIFORMS® very large channel sizes drastically reduce the clogging risk in the condensation zone.
ER 1682 RX Type 6 is used in the bottom part of the checker packing. It is compatible with the use of others CRUCIFORM® types in the remaining packing area.
Flue size: from 320 - 350 x 320 - 350 mm
Thickness: 30 mm
Heat exchange area: 10.6 - 9.0 m2/m3
Setting density: 546 - 464 kg/m3
| Shape | Weight |
|---|---|
| X shape: ER 1682 X6 | 22 kg |
| T shape: ER 1682 T6 | 17 kg |
| L shape: ER 1682 L6 | 12 kg |
