The Across International SR300 Stainless Steel Reactor is a large-scale industrial reactor system designed for pharmaceutical production, chemical synthesis, food processing, solvent recovery, and pilot-scale manufacturing.

Constructed with pharmaceutical-grade 316L stainless steel wetted components and an electropolished internal chamber, the SR300 provides exceptional durability, sanitary operation, and superior vacuum performance.

The system features a dual-jacket temperature control system, shell-and-tube condenser with 110 tubes, dual collection tanks, and a heavy-duty stainless steel frame, making it ideal for large-volume industrial processing environments.

Peer-reviewed models equipped with a pneumatic motor are approved for hazardous environments (C1D1).

Key Features

Pharmaceutical-Grade 316L Stainless Steel Construction

All wetted parts of the reactor vessel and lid are manufactured from 316L stainless steel, the industry standard for pharmaceutical and food processing.

Benefits include:

• Excellent corrosion resistance
• High chemical compatibility
• Long equipment lifespan
• Easy cleaning and sterilization

Structural components are manufactured from 304 stainless steel.

---

Electropolished Reactor Chamber

The reactor interior features an electropolished surface finish that improves sanitary performance and vacuum efficiency.

Electropolishing:

• Reduces surface roughness
• Smooths microscopic peaks and valleys
• Improves vacuum pressure performance
• Reduces out-gassing rates
• Improves pumping speed
• Reduces friction and wear
• Creates a semiconductor-grade sanitary surface

This finish is commonly required for pharmaceutical and food-grade processing applications.

Dual Jacket Temperature Control System

The SR300 reactor features a dual-jacket design with sealed insulation jacket.

Benefits include:

• Superior thermal efficiency
• Precise temperature control
• Reduced energy loss
• Consistent reaction performance

Center Fluid Jacket

• Capacity: 50 liters
• Pressure rating: 20 PSI

High-Efficiency Shell & Tube Condenser

The SR300 includes a shell-and-tube condenser with 110 tubes, designed for maximum condensation efficiency.

Specifications

• Condensing area: 1 m²
• Horizontally mounted condenser for lower center of gravity
• Top-mounted vacuum port for improved vapor flow

Flexible bellow connections reduce the risk of shipping damage.

---

Dual Collection Tank System

The system includes two 20L collection tanks with large sight glasses, allowing operators to drain condensate without breaking vacuum.

Collection Tank Options

• Option 1: 20L × 2 stainless tanks with manifold
