CRUCIFORMS® types
Type 2
Typical application
CRUCIFORMS® Type 2 is 40mm thick to reinforce resistance to corrosion.
ER 5312 RX Type 2 is used at the upper part of the regenerator packings operating with high carryover level or high exhaust gas velocities.
Flue size: 130x130mm up to 170x170mm
| Shape | Weight |
|---|---|
| X shape: ER 5312 X2 | 18.5kg |
| T shape: ER 5312 T2 | 15kg |
| L shape: ER 5312 L2 | 10kg |
Type 4
Typical application
The unique corrugated shape of CRUCIFORMS® Type 4 optimize the convection heat exchange for the higher efficiency.
ER 5312 Type 4 is used at the upper part of the regenerator packings.
Flue size: 140x140mm up to 180x180mm
| Shape | Weight |
|---|---|
| X shape: ER 5312 X4 | 20kg |
| T shape: ER 5312 T3 | 15kg |
| L shape: ER 5312 L3 | 11kg |
Type 8
Typical application
Half channel CRUCIFORMS® Type 8 for high fuel efficiency regenerator.
Increased heat exchange surface combined with the corrugated shape further boost the thermal efficiency of the entire regenerator.
ER 5312 Type 8 is dedicated to the top 5 to 3 courses of the checker packing. It is compatible with the use of others CRUCIFORM® types in the remaining packing area.
Flue size: 140x55mm up to 180x75mm
| Shape | Weight |
|---|---|
| X shape: ER 5312 X8 | 15.7kg |
| T shape: ER 5312 T8 P | 11kg |
