The various blade designs in our agitator product range have undergone significant research and testing, taking a scientific approach to agitation and heat exchange techniques that will optimize your process.
Selecting and fitting the correct agitator for your glass-lined vessel batch process is extremely important for the optimization of your reactor performance. The duty of the agitator must first be assessed, followed by the evaluation of flow pattern and regime as well as any special requirements that need to be taken into consideration, such as blending time, product concentration, and viscosity. Based on the relevant factors that comprise your unique process, an agitator design that matches the requirements of the application can be determined.
DDPS has an array of multi-functional blade designs to facilitate mixing in your vessel. The chart below illustrates the different types of agitator blades available and the characteristics of each, noting the different applications they are most suitable for.

GlasLock glass-lined steel agitators maximize process flexibility by allowing blades to be installed, removed, and changed to various pitches, depending on what works best for the application at hand. From a maintenance perspective, GlasLock blades are desirable because individual blades can be replaced if they become damaged, not the entire agitator; hence, the mechanical seal isn’t disturbed and repair costs are minimized. GlasLock blades are especially ideal for installation through the manway of a closed-welded GL reactor; their properties are beneficial in CTJ and SA reactor series as well.
OptiFoil, the newest design of GlasLock blades, combines the advantages of HydroFoil blades and Trapezoidal blades for optimized mixing. OptiFoil takes the features of these two designs and brings to the market a solution that ensures a high axial flow for suspension processes and also facilitates the operation of minimum volumes. The pitch angle of these blades gives a smoother contact with the product than the vertical trapezoidal blades, and is specifically recommended to avoid the alteration of fragile crystals.
Additional advantages of this unique blade system include:
One-piece construction agitators have a restricted field of application because they need a large opening to be installed, and encounter additional issues including sealing problems, difficulty cleaning, and mandatory dismantling of the drive for any maintenance. Still, there are certain applications in which this design is sufficient.
