PPG Semco® Model 1188 HD Mixer — ATEX Class II Certified | CE Approved | Fully Pneumatic High-Viscosity Mixing

Heavy-duty. Explosion-safe. Fully pneumatic. Engineered for high-viscosity sealant mixing in the most demanding and volatile industrial environments.

The PPG Semco® Model 1188 HD Mixer is a heavy-duty, fully pneumatic mixing system equipped with a robust motor engineered to thoroughly mix high-viscosity materials in Semkit® packages. With ATEX Class II certification and CE approval, it is purpose-built for safe, reliable operation in volatile surface industrial environments where explosive atmospheres — gas, vapor, mist, or dust — may be present.
Always follow applicable ATEX safety protocols, site-specific hazardous area classifications, and manufacturer guidelines before operating this equipment. Refer to the manufacturer's Safety Data Sheet (SDS) before handling Semkit® materials.

Soft-Start Technology — Protecting High-Viscosity Mixing

⚙️
Why Soft-Start Matters for High-Viscosity Materials

The 1188 HD features a built-in timer and valve soft-start system that initiates the air motor at a slow speed, then automatically ramps up to full operating speed after 3 seconds. This critical design feature prevents the open spoke from breaking when engaging very viscous materials — protecting both the dasher rod assembly and the integrity of your Semkit® package from the first stroke.

Compatible Semkit® Package Configurations

Single switch adjustment enables mixing across all of the following configurations:
Cartridge Size Dasher Rod Length Configuration
2.5 oz 6 inch 2.5 oz / 6" Rod
2.5 oz 8 inch 2.5 oz / 8" Rod
6 oz 6 inch 6 oz / 6" Rod
6 oz 8 inch 6 oz / 8" Rod
8 oz 8 inch 8 oz / 8" Rod

Key Features & Benefits

🔥 ATEX Class II Certified

Purpose-built for volatile surface industrial environments — ATEX Class II certification (Directive 2014/34/EU) confirms safe operation where explosive gas, vapor, mist, or dust atmospheres may be present, meeting the most stringent European safety standards.

⚙️ Soft-Start Ramp Technology

The built-in timer and valve system starts the air motor slowly and ramps to full speed after 3 seconds — preventing open spoke breakage when engaging very high-viscosity materials and extending the service life of dasher rod assemblies.

💨 Fully Pneumatic — Non-Electrical

Operates entirely on 85–95 PSI dry compressed air at 3 CFM — no electrical power required. Ideal for hazardous environments where electrical equipment poses an ignition risk, and for locations where power access is unavailable or restricted.

🏋️ Robust High-Viscosity Motor

Equipped with a robust, high-torque air motor specifically engineered to thoroughly mix high-viscosity sealants, adhesives, and potting compounds that would stall or damage standard mixing equipment.

🔧 Single-Switch Multi-Config Operation

A single switch adjustment enables seamless mixing across five Semkit® package configurations — 2.5 oz and 6 oz with 6" or 8" dasher rods, and 8 oz with 8" dasher rod — maximizing operational flexibility with minimal setup time.

🛡️ MIL-STD-810F Salt Fog Tested

Tested to MIL-STD-810F Method 509.4 salt fog resistance standards — confirming proven corrosion resistance for deployment in harsh marine, coastal, and high-humidity industrial environments where equipment longevity is critical.

Understanding ATEX Class II & CE Approval

🔥 What ATEX Class II Means
Directive: 2014/34/EU — Equipment for use in potentially explosive atmospheres
Group II: Surface industrial environments (not underground mines) with explosive atmosphere risk
Covers: Gas, vapor, mist (Zone G) and combustible dust (Zone D) explosive atmospheres
Zones: Applicable across Zone 1/21 and Zone 2/22 hazardous area classifications
🇪🇺 What CE Approval Means
Marking: Conformité Européenne — mandatory for products placed on the EEA single market
Compliance: Confirms conformity with all applicable European health, safety, and environmental directives
ATEX link: For ATEX products, CE confirms proper conformity assessment procedures were followed under Directive 2014/34/EU
Market access: Legally permits free movement and sale throughout the European Economic Area
