Trays

Our objective is to blind and secure the confined space (tower/column), be in and out efficiently, support startup, and for your equipment to function at designed flowrate producing high quality product.

To achieve that end . . . internals are critical components of process equipment and must be installed correctly for a process unit to operate at peak performance. Ohmstede Industrial Services provides skilled craft experienced in assembling, maintaining, repair and retrofitting tower trays, packing, parts and associated hardware. Limited access and work space is normal and requires special equipment and safety procedures for work to be performed efficiently. We have established relationships with part and hardware manufacturers for obtaining parts due to changes in work scope or discovery items.
