CRUCIFORMS® types
Type 3
Typical application
CRUCIFORMS® Type 3 is 30mm thick with a flat, high heat exchange surface.
ER 1621 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: 867 - 570 kg/m3
| Shape | Weight |
|---|---|
| X shape: ER 1621 X3 | 20.5 kg |
| T shape: ER 1621 T3 | 16.0 kg |
| L shape: ER 1621 L3 | 11.5 kg |
Type 4
Typical application
The unique corrugated shape of CRUCIFORMS® Type 4 optimize the convective heat exchange for higher thermal efficiency.
ER 1621 RX Type 4 is typically used from the middle to the top part of the regenerator packings.
