UP55 / Semiconductor Drum
A 55-gallon Tri-Layer HDPE drum for semiconductor and high-purity process chemicals. One seamless, blow-molded body combines a virgin HDPE wetted layer, a structural core, and a UV-stabilized exterior.
One Body. Three Co-Extruded Layers.
Virgin HDPE at the wetted surface.
Seamless, blow-molded construction from fill to dispense.
UP55 / Assembled Drum
Containment Engineered in Three Layers
Clean contact inside, structural support through the core, and a protective exterior.
Ultra-Pure Virgin HDPE
Structural HDPE Core
UV-Stabilized HDPE
Controlled Top Access
The extended top chime shields installed closures during handling and stacking. The KoLink™ Dispense Head seats only on a matching chemical-service code.
UP55: Ultra-Pure 55-Gal Drum with KoLink™ Fluid Interface & Accessories
Ultra-pure inner layer for chemical contact, structural middle layer, and protective outer skin. Extended chime to guard drum ports & closures.
UP275 IBCs & UP55 Drums Offer the Lowest in-Class Particle Counts; Under 100 ppt extractable trace metals, per element, verified per lot.
Diptube and sump geometry leaves under 200mL in a 55-gallon Kurko drum at empty and under 0.1% of fill volume in Kurko 275 gallon IBCs.
One KoLink™ dispense head and insert, compatible across all 5 containers, take Kurko coding elements to configure the same hardware to any chemical service.
Achieved by one standardized containment system: reconfigurable fill-and-dispense hardware across drums & IBCs, pooled inventory, denser freight.
The UP55 carries the aqueous side of semiconductor wet processing — the acids, bases, oxidizers, etchants, and slurries that move in drum quantities from a producer's fill line to a fab's dispense room. Flammable solvents sit outside its service set and run on the SS330 all-stainless platform, so each chemistry rides the body built for it.
Drum-quantity delivery of the aqueous chemistries behind wafer cleaning, etch, and planarization steps — the lots that move below IBC volume.
The Tri-Layer HDPE wetted path is built for aqueous ultra-high-purity duty; wetted seals are PFA, with no elastomers in the wetted path.
Ships ready for fill-line qualification at the producer, coded to the assigned chemical service for dispense at the fab.
Sealed, continuous-vent, and manual-relief closures are assigned per chemical service — venting only where the service requires it.
Service is confirmed per chemistry, concentration, and closure configuration at qualification.
Platform specifications for the UP55 as it ships. Items still in engineering release are marked to be confirmed rather than estimated.
Tri-Layer Construction
The only surface the chemistry ever touches. Formed from virgin HDPE, it keeps the contact surface clean and consistent from fill through dispense.
The core carries the load. The thickest of the three layers, it gives the drum its stiffness, stacking strength, and impact resistance through filling, handling, and transport.
The exterior takes the environment. UV-stabilized HDPE shields the drum from sunlight and handling wear through staging, transport, and storage — so the layers beneath keep doing their jobs.
Top Head
The working port. A 2-inch S62×5 modified buttress port carries the KoLink™ Keyed Diptube Insert; the coded Dispense Head seats here at the fab.
The service port. A second 2-inch port on 13.50-inch centers takes the fill at the producer and carries the vent closure the chemical service calls for.
The guard. The chime stands proud of the head, so installed closures and the Keyed Diptube Insert sit below the contact surface in handling and two-high stacking.
The serviceable hardware. Sealed, continuous-vent, and manual-relief shipping caps thread onto the ports and are assigned per chemical service; the Keyed Diptube Insert threads out for service and coding.
