The available trays range from conventional to high performance, and the latest developments of ultra-system limit trays. Within the family of conventional trays, we offer:

Sulzer proprietary SVG™ (fixed) and BDH™ (floating) valves
Round and caged floating valves
Slit Trays™
Sieve, bubble cap, cartridge, dual flow, and other trays

Structured packings
Structured packing is one of our core abilities. Over 50 years of experience in development, design, and production of this type of packing makes us your best partner to find the optimum solution for your application.
Random packings
Random packing has been used for fractionation, absorption and stripping operations in gas, refinery and chemical plants for many years and the benefits are well established. Furthermore, ease of replacement and storage make random packing the ideal choice for systems with heavy fouling or corrosion where packing is frequently replaced.


We offer a wide range of different types of mist eliminators for the separation of entrained liquid. When choosing the appropriate equipment, droplet capture mechanism is the key for successful mist elimination.
