ABOUT US
"Ceramic Filter & Ceramic Catalyst Filter"
Selah Co., Ltd. produces ceramic filters and ceramic catalyst filters using its own molding technology and supplies them to small ship diesel engine exhaust gas simultaneous reduction devices and large building emergency generator smoke reduction devices.
As atmospheric environmental problems caused by greenhouse gases and fine dust increasingly threaten our lives, the entire world is making efforts to fundamentally address serious environmental issues.
Accordingly, we promise to take the lead in environmental improvement through technological development of core materials and simultaneous reduction devices using them,
responding to strengthened domestic and international environmental regulations,
and leading the way in technology.
Please watch over us with much interest and love, and also give us much advice and encouragement.

CERAMIC MEMBRANE FILTER
Ceramic membrane filters primarily create nano-sized pores on the surface through SiC membrane coating to form a membrane film, and can capture more than 99.9% of dust particles due to the cake phenomenon.

CERAMIC CATALYST FILTER
CERAMIC CATALYST FILTER FILTRATION PRINCIPLE
-
The ceramic catalyst filter has a wear-resistant membrane coating with excellent dust capture and removal performance on the filter surface, maintaining the same pressure loss and capture efficiency throughout the use cycle, and
reacts when Nox passes through the SCR catalyst contained in the filter wall to emit clean air. -
When using urea water as a reducing agent, it provides a stable simultaneous reduction process without secondary problems due to slip.

CERAMIC FILTERS
▶PRODUCT INTRODUCTION
For simultaneous treatment of high temperature exhaust gas fine dust and harmful gases at 250℃ ~ 500℃
As a core material of ceramic catalyst filters for simultaneous reduction of Dust + NOx generated from various industrial combustion processes, it is widely designed and applied with hybrid functions to reduce exhaust gases from diesel engines and large-scale industrial process facilities through filter enlargement and selective catalyst support.
▶PRODUCT FEATURES
-
Stable use at high temperatures of 500℃
-
Safety from filter damage/fire hazard due to flame
-
High capture efficiency of 99.9% for the same period of use
-
Optional NOx/VOC's reduction catalyst support available
-
Advantages such as excellent durability/wear resistance/chemical resistance, etc.
-
Low pressure loss of the filter: less than 20mmH₂O
