Cruciform types

Type 2

Typical application

CRUCIFORM® Type 2 is 40mm thick to reinforce resistance to corrosion.

ER 1682 RX Type 2 is used in the middle and bottom part of the checker packing with high corrosion level in the condensation area.

Flue size: 130x130mm up to 170x170mm

Shape Weight

T shape: ER 1682 T2 17kg
L shape: ER 1682 L2 12kg

Type 3

Typical application

CRUCIFORM® 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: 140x140mm up to 180x180mm

T shape: ER 1682 T3 17.5kg
L shape: ER 1682 L3 12kg

Type 4

Typical application

The unique corrugated shape of CRUCIFORM® 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: 140x140mm up to 180x180mm

Shape Weight
X shape: ER 1682 X4 23kg
T shape: ER 1682 T3 17.5kg
L shape: ER 1682 L3 12kg

Type 6

Typical application

Type 6 CRUCIFORM® 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.
