Increased energy efficiencies

Effective system design means power input can be reduced by achieving:

• Optimum heat transfer

• Uniform dissipation of energy

• Low energy demand

Energy saving of up to 35 per cent have been achieved.

Power applications and

advantages

Homogenisation

A high performance agitator Turbofoil (3.2kW) needs 35% less energy

compared to an Impeller (5.1kW). On the basis of BE 6300, 1000

kg/m3, 20 mPas.

Gas Dispersion

Replacing a Standard Impeller with a CBT agitator can triple gas

absorption rates. On the basis of 1kW/m3, 630 m3 instead of 220 m3/h.

Suspension

For solid particles distribution needs, the Pitched Blade Turbine (PBT) AT

4.2 kW can lead to energy savings of 3.7 kW over the Standard Impeller,

representing a considerable cost saving during the year.

Crystallisation

Replacing the anchor (ANC) with the double stage Turbofoil can increase

output by 30%.

Safety and environmental

protectionThe system is corrosive resistant and considerably reduces the risk of

leakage caused by replacing gaskets. Cryo-Lock II enables gasket size

for BE 6300 vessels to be reduced by 2,500 mm compared to the CE

6300 versions, resulting in a 60% reduced leakage rate at vacuum

conditions.

Performance effectivenessFurther cost efficiencies result from Cryo-Lock’s unique one piece design

which means the single shaft stays in place so only the blade is changed.®GMM Pfaudler’s Glassteel reactor technology means vessel and agitator

life is maximised for mixing corrosive substances.

All these factors contribute to minimal downtimes and maintenance

costs.

Total FlexibilityGMM Pfaudler mixing technology offers total flexibility. You can respond

immediately to changing market conditions by:

• Reconfiguring your Glasteel reactor

• Modifying or completely changing the mixing operation.

Liquid nitrogen cooling enables the blade to be easily accessed and removed quickly. Cryo-Lock impellers in a BE vessel can be changed in less than two hours compared to two days or more for standard impeller in a CE vessel design.

There is also no need to replace a Cryo-Lock agitator shaft when only the impeller has suffered damage. This can be changed inside the cleaned reactor without removing the shaft, drive, motor or access cover.

Replacement agitators can also be stored economically.

With some products, switching to a turbofoil blade from a standard fixed agitator can

lead to mixing times being reduced by half while pumping capacity is almost doubled.

options

Impeller and baffle

configurations can be adapted

to serve all basis process

operations. In addition, other

factors, such as drive speed

and baffle arrangement, can be

altered to enable most impellers

to be used in more than one of

the five basic unit operations.

MFI Multi-Flight Impeller• where single impeller is inadequate• for high viscosity fluids• lightweight solids in narrow vessels

RCI Retreat Curve Impeller• versatile, general purpose design• high radial flow• wider baffling required• insensitive to viscosity variations• suitable for low liquid levels, small batches

TBF Turbofoil• low shear forces• high axial flow at relatively low baffling• low torque• low power-consumption

CBT Curved Blade Turbine• high shear• radial flow• wider baffling required with low viscous

fluids

GMM PFAUDLER LTD. the Indian Pioneer in the manufacture of glass

lined reactors - produces mixing systems to meet any application,

process condition, mixing operation and viscosity range.

GMM Pfaudler can recommend the optimum mixing system for specific

requirements and show how it can be modified or changed. If required, a

custom impeller or agitator can also be designed and built.

Significant cost savings can be achieved by “mixing and matching”

impellers to:

• Optimise product quality and yield

• Reduce mixing/process times

• Optimise the agitation process

• Maximise energy efficiencies

• Ensure performance effectiveness

• Respond to changing market conditions

GMM Pfaudler Mixing Systems

• Improve product quality and yield while minimising costs.

Optimal agitation process

The Cryo-Lock option is a complete all in one mixing system based on a

single reactor with a wide variety of interchangeable agitator blades. This

flexibility means blade configurations can be altered to best suit the

requirements of each product.

For all mixing systems, GMM Pfaudler can also produce computer

simulations to maximise the efficiencies in each of the five basic

processes:

• Mixing/Blending

• Suspension

• Gas Absorption/Dispersion

• Emulsification

• Heat Transfer
