Product Description
|
Product parameters:
Introduction: The advantage of monolithic honeycombs is that they provide the highest possible heat recovery with the lowest possible pressure drop. A defined laminar gas flow prevents blocking, particle adsorption and corrosion attacks. RTO units equipped with honeycomb ceramic heat media are easy and cost-efficient to operate and maintain. They are most reliable and economical solution for thermal oxidizers.
