The Mark V is designed to accurately and consistently duplicate any pulp bleaching plant conditions for any bleaching stage. Its patented bowl and rotor combined with complete control over rotor speed can simulate any type of mixer found in the plant without adversely effecting the physical characteristics of the pulp. With the Mark V Mixer you have complete control over mixing, residence times, and temperatures. The control of pressure enables the simulation of any bleaching tower.

This specially designed fluffing rotor and bowl produces high intensity mixing and fluffing of high consistency pulps.

Prevents pulp from plugging the exhaust ports. It is placed between the top of the bowl and lid, isolating the exhaust port from pulp while allowing exhaust gasses to pass through the center of the plate to the exhaust valves.

These bowl extensions slide directly onto existing 2 and 4 liter bowls to increase capacity by 3 liters. When used with your existing rotor, the conditions formed are ideal for low consistency, high volume experiments. The optional extension rotors enable the extensions to be used for medium consistency experiments.

Allows you to quickly and easily obtain samples of volatile reaction products for environmental testing.

Allows you to extract pulp from the bowl and wash it in one easy step.

You can inject up to 100 mL of chemicals while the reactor vessel is under pressure.

Teflon coating helps provide chemical resistance during experiments.

The Ozone Caddy if a fully automated system that produces, analyzes, and stores up to 10 grams of ozone in less than an hour. It then uses a liquid compression system to precisely deliver any amount of ozone up to the full 10 grams at any pressure up to a 125 psig. Unused or unreacted ozone is destroyed in a built-in scrubber system.

Produces, analyzes, stores, and pressurizes up to 10 grams of ozone in less than one hour. This ozone can be injected at any rate (including multiple injections) and at any pressure between 15 and 125 psig. The Ozone Caddy can also feed a continuous stream of ozone.

10 grams of ozone produced in less than an hour will usually last through 4 experiments or ½ to a full day of work.

In automatic mode, the Ozone Caddy provides excellent control and versatility for pulp bleaching experiments with minimal operator interaction. In the manual mode, the Ozone Caddy can be used as a stand alone ozone system to deliver large, controlled and pressurized amounts of ozone for other purposes. It can also be used for pressurization and precise delivery of other gases.

After initial setup, the operator needs only to press a button and let the Ozone Caddy do its work.

The Ozone Caddy is on wheels but is too large to be regularly moved. It can be floor mounted.

Ozone is generated and pressurized as it fills a holding tank. When the tank is filled a small amount is discharged into a chamber and analyzed before it is injected for bleaching. Thus the concentration of the actual gas to be used in the experiment is precisely know. The remaining ozone not injected can be analyzed to check for deterioration.

Coded stainless steel vessels. All contact metallurgy is stainless steel. Injection pressure is rated up to 125psig.

Free volume is the portion of the mixing bowl which can be occupied by gasses but not by pulp. In a normal mixing bowl this volume is very small and it limits the charge of ozone which can be applied to the pulp since ozone can be concentrated much lees than other bleaching chemicals. The FV extensions fits on the existing 2 or 4 liter bowl and greatly increases the free volume. This is due to a special design which keeps the pulp on the bottom portion of the bowl while leaving the top portion of the bowl free to be filled with ozone. As the ozone is injected it is forces downward and is thoroughly mixed with the pulp. This enables a much larger charge of ozone to be applied to a given amount of pulp compared to a normal bowl. The FV extensions are especially important when it is desired to get all of the ozone in the bowl in one injections rather than in multiple injections.

The Ozone Residual Traps captures unreacted ozone exiting the mixer bowl. This allows for a precise calculation of the exact charge applied to the pulp.

The Ozone Seal Kit includes all the necessary seals and o-rings needed for ozone bleaching.

The Ozone Cart is offered in a single or dual cylinder capacity. The Single Cylinder Ozone Cart is a compact mobile unit that generates and analyzes ozone. It uses a dry compression system to inject up to 0.6 grams of ozone every five minutes. The Dual Cylinder Ozone Cart performs the same , but it can inject up to 1.2 grams of ozone every five minutes. The Ozone Cart uses a dry catalyst system to destroy unused ozone.

Produces, and compresses up to 0.6 grams of ozone every five minutes (the dual cylinder produces up to 1.2 grams). The amount injected can be either 20%. 40%, 60%, 80% or 100% of the maximum compression cylinder volume. Ozone is injected up to 125 psig. Multiple injections are possible. However, control over injection pressure is limited.

The Ozone Cart provides excellent control and versatility for routine pulp bleaching experiments with minimal operator interaction. Since the Ozone Cart uses the controls of the Mark V Mixer/Reactor, it can not be a stand alone system like the Ozone Caddy.

Although operator interaction is minimal, the operator must monitor the operator of the Ozone Cart because of its lack of automation.

The Ozone Caddy is on wheels and is quite mobile.

The Ozone Cart is less accurate than the Ozone Caddy because the flow rate and thus the concentration of the ozone varies as the cylinder fills. The concentration is analyzed from a sample taken at one point in time during the filling of the cylinder and may differ slightly from the actual concentration of the ozone in the cylinder after it is filled. However, the reproducibly of the charge level from injection to injection is very good and can be relied upon to remain the same throughout the experiment.

All contact metallurgy is stainless steel. Injection pressure is rated up to 125psig.
