The main tower for MDI separation requires mesh packing, with very low pressure drop requirements; which manufacturers can supply it? Thank you!

Yes, for MDI units, we used Sulzer’s BX packing in the past; it was just too expensive. For our new units, we used the domestic CY700 packing, but it failed to meet the separation requirements. Later, we switched to Kefukei’s BX packing, which is identical to Sulzer’s product but is cheaper and meets the separation requirements
Which manufacturer’s wire mesh corrugated packing has the original poster chosen now?
