Orca™ MicroBulk Delivery

All Orca™ MicroBulk Delivery models feature an exclusive "Smart" Flowcom® flow metering system that contains no moving parts for an accurate, trouble-free service life. The Orca system controls automatically sense the Perma-Cyl® MicroBulk Storage System float shut-off for a safe and reliable fill.

The Orca Advantage

  • Especially suited to urban areas and reaches locations that are inaccessible to traditional bulk supply tankers 
  • When connected to a Perma-Cyl® MicroBulk Storage System, Orca automatically terminates the delivery for a safe and reliable single-hose fill
  • For inert service, the Orca uses a variety of submerged pumps for a safe, convenient and fast fill, without product loss. Other models include innovative pump-less designs that utilize the cryogenic vaporization energy to deliver the liquid reliably and quietly
  • National Institute of Standards & Tehcnology (NIST) in the US and California Weights & Measures approved metering system
  • Stainless steel and bronze plumbing for long service life
  • Robust inner vessel support system affords protection even on the most rugged roads
Orca XT, ST & HL Models

Designed for smaller markets or as a starter system, the XT Series is a pumpless design that delivers product efficiently from an innovative Pulse Technology process. The ST and HL models incorporate an external pump for oxygen service or an innovative submerged pump for inert service, eliminating cool down losses and reduces delivery time.

Orca VHP Models

The Orca VHP Delivery System provides the capability to fill tanks operating at pressures up to 500 psig, eliminating the need for costly and time-consuming tank blowdowns. Coupled with our existing automated fill system, this new pump technology allows faster delivery times without interrupting ongoing facility operations.

Orca CO2 Models

We've adapted our Orca™ MicroBulk Delivery System specifically for filling the Carbo Series and Perma-Max™ CO2 tanks. The stainless steel inner vessel on this unit is protected by a high quality vacuum with super insulation for minimal heat transfer. This insulation system eliminates just-in-time filling and provides colder CO2 necessary for a single-hose, no loss fill to the storage vessel.

Flowcom® Flow Metering Systems

All Orca delivery systems are equipped with the Flowcom flow meter system available with data options. The Flowcom stainless steel meter section contains no moving parts for low maintenance, calibration stability, dry ice resistance, and has a lifetime warranty.
