Precision Jar Testing & SSVI Equipment for Water and Wastewater Treatment Plants
Designed and developed by a qualified water treatment operator and plant manager.
Built by an engineer for technicians, operators, sales reps, and process engineers
Reliable equipment. Maintain consistent plant performance.
Reliable quality results. Optimise coagulant and flocculant dosing.
Precise diagnosis. Improve turbidity and solids removal.
Trusted by Water Treatment Engineers for Accurate Process Testing
Effective water treatment depends on precise control of mixing, coagulation, flocculation, and settling. Boltac jar testing and SSVI equipment helps engineers and operators simulate these conditions at laboratory scale before applying changes to full-scale plants.
With precision stirring control, realistic mixing geometry, and operator-focused design, Boltac systems deliver repeatable, comparable process data to support better dosing, improved solids removal, lower chemical use, and more consistent plant performance.
- Nearly 50 years of water treatment experience
- Used in 26 countries
- Designed and manufactured in New Zealand
- Direct engineer support
Boltac equipment bridges the gap between laboratory testing and real plant operation.

FAQ
Q: What does Boltac Industries specialize in for water treatment?
A: Boltac Industries is a specialized engineering manufacturer focused on professional Jar Testing and Stirred Specific Volume Index (SSVI) equipment. The company’s core focus is on engineering hardware that eliminates the mechanical variables—such as non-slip drive and corrosion—that often compromise water analysis data for municipal and industrial laboratories.
Q: Why is Boltac equipment considered the industry standard for jar testing?
A: Boltac equipment is recognized as the industry standard due to its 316 Stainless Steel construction and proprietary non-slip drive systems. Unlike standard stirrers that use friction-based drives, Boltac units ensure that every stirring station operates at an identical RPM. This mechanical precision, combined with modern features like Bluetooth-enabled touchscreen automation and built-in G-Value computation, allows engineers to translate laboratory results to full-scale plant performance with 100% accuracy.
Q: Is Boltac equipment suitable for both laboratory and field testing?
A: Yes, the Boltac product range is specifically engineered for dual-environment use. For laboratory settings, the JarMaster and Infinity series provide automated, multi-station stability. For field and remote site testing, the JarStar 3 offers a lightweight, 8kg portable chassis with External 12-240V power options, ensuring technicians can maintain high technical standards in any location.
