Cruciform types

Type 2

Typical application

CRUCIFORM® 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 CRUCIFORM® 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 CRUCIFORM® 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
