WIGGENS 13365 Series Pneumatic Stirrer

Overview

The WIGGENS 13365 Series Pneumatic Stirrer is an intrinsically safe mixing solution engineered for laboratories and industrial process environments where electrical spark hazards must be eliminated. Unlike electric stirrers, this system operates exclusively on compressed air—eliminating ignition risk in flammable atmospheres classified under ATEX Zone 1/2 or NEC Class I, Division 1/2. Its core principle relies on positive-displacement vane-type pneumatic motors, delivering precise torque-speed characteristics without electromagnetic interference or thermal runaway. The 13365-05 variant delivers high-speed, low-torque performance ideal for low-viscosity solvents, paints, thin coatings, and light hydrocarbons. In contrast, the 13365-10 and 13370-10 models provide enhanced torque at lower speeds, supporting medium-to-high viscosity fluids including resins, adhesives, slurries, and polymer dispersions. All units are fully assembled with integrated air filtration, pressure regulation, and lubrication—requiring only connection to a clean, dry compressed air supply (35–100 psi) for immediate operation.

Key Features

• Intrinsically safe operation: No electrical components; compliant with hazardous area requirements when used with certified air supply systems
• Dual operational variants: 13365-05 (200–10,000 rpm, optimized for speed), 13365-10 (50–1,200 rpm, optimized for torque), and 13370-10 (300–3,000 rpm, high-torque configuration with reinforced 12.7 mm shaft)
• Integrated air management: Built-in coalescing filter, pressure regulator, and oiler ensure consistent motor performance and extended service life
• Robust mechanical architecture: Precision-machined aluminum housing, AISI 316 stainless steel drive shaft (Ø9.5 mm or Ø12.7 mm), and 64 mm diameter impeller resistant to corrosion from organic solvents, mineral acids, and caustic media
• Variable speed control: Smooth, stepless adjustment via inline needle valve—no electronic controllers required
• Low maintenance design: Vane-type air motor requires no periodic brush replacement or winding inspection; typical service interval exceeds 10,000 operating hours under standard conditions
• Modular accessory compatibility: Supports optional PTFE-coated or fully PTFE impellers for aggressive chemical resistance; interchangeable shafts and clamping fixtures (e.g., compatible with Wittstock 9124 universal stand)

Sample Compatibility & Compliance

The 13365 Series accommodates a broad range of sample types—from volatile organic solvents (e.g., acetone, toluene, xylene) and low-surface-tension coatings to shear-thinning polymer solutions and abrasive particulate suspensions. Its non-sparking construction meets functional safety expectations for use in pharmaceutical solvent blending, paint formulation labs, petrochemical QC testing, and electronics-grade chemical handling. While not individually ATEX-certified, the system is designed to operate safely within certified hazardous zones when supplied with filtered, oil-free air meeting ISO 8573-1 Class 2:2:2 specifications. It supports GLP-compliant documentation workflows through traceable air pressure logs and manual speed calibration records. For regulated environments, users may integrate external pressure transducers and analog tachometers to satisfy 21 CFR Part 11 data integrity requirements.

Software & Data Management

This is a hardware-only, analog-controlled instrument with no embedded firmware or digital interface. Speed is monitored externally using contact or non-contact tachometers (e.g., optical or magnetic pickup sensors), enabling integration into third-party SCADA or LIMS platforms via 4–20 mA or 0–10 V analog outputs (when paired with optional signal conditioners). All operational parameters—including inlet pressure, flow rate (cfm), and estimated power draw—are documented in the technical datasheet for audit readiness. Calibration certificates for included air filters and regulators can be provided upon request to support ISO/IEC 17025 laboratory accreditation.

Applications

• Flammable solvent homogenization in explosion-proof fume hoods or gloveboxes
• Batch mixing of epoxy resins, urethanes, and silicone elastomers requiring controlled shear input
• QC testing of paint viscosity stability during dispersion and aging studies
• Preparation of catalyst slurries and battery electrode slurries in inert-atmosphere reactors
• Continuous agitation of cleaning baths containing chlorinated or fluorinated solvents
• Stirring of high-purity reagents in semiconductor fab tooling and photomask development labs

FAQ

Is the WIGGENS 13365 Series ATEX-certified?
No—the unit itself does not carry ATEX marking. However, it is widely deployed in ATEX Zone 1/2 environments when supplied with certified air treatment systems and installed per IEC 60079-14 guidelines.
What compressed air quality is required?
ISO 8573-1 Class 2:2:2 (solid particle ≤ 0.1 µm, dew point ≤ −40°C, oil content ≤ 0.1 mg/m³) is recommended for optimal vane motor longevity.
Can the stirrer be used underwater or in vacuum chambers?
No—it is rated for ambient atmospheric operation only; submersion or vacuum exposure will compromise air motor sealing and filtration integrity.
Does the system include speed feedback or digital logging capability?
Not natively. Real-time speed monitoring requires external tachometry; data logging must be implemented via user-supplied instrumentation.
Are spare parts and service kits available globally?
Yes—WIGGENS maintains authorized distributor networks across EMEA, North America, and APAC supplying genuine replacement vanes, O-rings, filters, and PTFE impellers with documented shelf-life tracking.
