PULSAIR Terminology

PULSAIR Terminology

Accumulator Plates: They are typically made from 3/16" carbon steel. Accumulator plates are sized according to the tank diameter and shape. Welded to each plate are three clips, attachment devices made of 3/16" carbon steel. Once the plates are properly positioned about the tank, the clips are welded to the tank, effectively anchoring the plates to the tank. Each plate has a 4" NPT pipe nipple that is welded over the center hole. The nipple is used to plumb the plate to the injection line. Plates are made from any readily available material that is compatible when carbon steel is not.

Bubble Power: A quarterly newsletter published by PULSAIR for its customers and sales reps.

Controller: Honeywell TDC-3000 or other PLC based system for managing PULSAIR Technology.

Dwell: The time between injected pulses

Double Accumulator Plate: An arrangement of two accumulator plates whereby the pulse comes out between the two plates instead of a single plate and the tank bottom. Double accumulators are used in tanks with delicate surfaces where attachment could weaken the tanks integrity or direct pulsing against the tank could damage the surface.

Electro-Pneumatic Interface (EPI): Converts electrical signals from a PLC or other control device into pneumatic pilot signals that open and close the injection valves.

E-PROM: Erasable Programmable Read-Only Memory. This is a semi-conductor chip that is programmed to execute a series of instructions. PULSAIR programs E-PROMs and then installs them into PLC control devices such as the PPC. The E-PROM is customized to each customer's needs. When a customers needs change, for example, a need to add more tanks, PULSAIR will program a new E-PROM and exchange if for the customers existing E-PROM.

Hardware Kit, PULSAIR System: Hardware kit refers to all of the PULSAIR components that are installed at the tank including Electrical-Pneumatic Interface (EPI), injection valves, filter, regulator, accumulator plates and installation manual. PULSAIR refers to hardware kits when selling Distributive Control System (DCS) licenses or tanks that are to be added to the PPC at a later date.

Injection Line: All plumbing pipes that carry compressed air from the injection valve to the point of injection beneath the accumulator plate(s).

Injection Time: The length of time the injection valve(s) is open. Typically 0.5 seconds

Injection Valve: Pneumatically actuated valve located in the injection line that releases the pulse into the tank, beneath the accumulator plate. See Injection Valves

Intermittent Mixing: When a PULSAIR system is operated in a pre-determined on /off mode to take advantage of the kinetic energy or flywheel effect created by PULSAIR mixing.

Injection Pressure: The pressure at which compressed air is sent to the accumulator plates in a tank.

On Delay: The pre-programmed time to start the PULSAIR mixing system.

Pneumatic Controller: All non electric versions of the PULSAIR controller for Flat Tank (FT), Horizontal Tank (HT) or V-Bottomed Tank (VTS). The control device on the 5-55 Drum-Stick, 10-55 Tote-Stick, PTM-2000 Series or TM-2000 Series portable mixers is often referred to as the pneumatic controller or power head. Pneumatic controllers require no electricity to operate. However, pneumatic controllers can be turned on and off electrically using a solenoid (See RC option and A General Discussion of Pneumatic Controllers).

Process Mixing Time: The mixing time required to complete a batch in a specific tank

PULSAIR Technology: The Patented process of sequentially injecting high pressure air into a liquid such that it forms a single bubble, generating powerful mixing currents inside the tank. (See How PULSAIR Works.)

Pulse Confirmation Signal: The feedback signal that is sent to the controller after the injection valve has been successfully opened and closed.

Tote A steel container with a 42" by 48" base that is used extensively in the US. Tote height is given by the volume, usually 350 and 550 US gallons. Many totes have standard 22-1/2" drum opening in the center of the top that can be removed. This cover has a 2" bung in the center. See PULSAIR 10-55 Tote-Stick.
