SONASIL
- Calcium Silicate Insulation (CSI)
SONASIL
CSI is a thermal energy conservation product, containing reinforcing
fibres (non-asbestos). It
is a versatile insulation offering the thermal efficiency of
flexible insulation like Mineral Wool and the strength of
conventional Insulation Bricks. It improves production and
other related issues, all within a very small pay-back period
upto a service temperature of 1000 șC.

Others
|
:
Significant fuel savings can be obtained in Ceramics,
Rolling Mills, Foundries and various industries, who
use thermal equipments at high temperature.
|
|
|
As a thumb rule, wherever refractory bricks are being used, Calcium Silicate Insulation should be used as a back-up layer.
|
|
CSI is
un-matched in places
where a backup insulation is needed or where there is likely
possibility of insulation being subject to accidental exposure
to water or impact loads or foot traffic.
|
|
|
|
CSI
decreases loss of heat & reduces surface temperature
significantly and
|
|
|
Decreases fuel cost & conserves
natural recourses
Leads to faster processing
Improves production efficiency
Increases life of equipment
Makes surrounding atmosphere more comfortable for
working, etc.
|
|
|
|
It is available in slabs, bevelled lags, radiused
& bevelled lags,
pipes and in powder form for insulating complex shapes.
