Still Bottoms Safety Discharge Package Our solvent reclamation systems are designed for precise control and safe use, processing virtually any flammable or combustible solvent waste, including reactive chemistries such as waste containing nitrocellulose or cross-linking resins. Our safety discharge package allows operators to easily discharge distillation bottoms. Our Still Bottoms Discharge Safety Kit includes: Drum positioning ring for proper alignment Drum cart to easily position the drum Drum-in-place sensor prevents discharge without drum Drum full sensor assists operator, prevents overfill Safety interlocks to the dump mechanism Rear vent opening to exhaust fumes away from operator Long-Term, Consistent Output Scraper Blade Assembly The SCR solvent recycling system is designed for maximum efficiency. Our patented rotating scraper blade assembly: cleans the heat transfer surface of sludge buildup for high efficiency all the heat transfer area below the liquid operation level is cleaned solids are rolled off the side walls and down into the conical bottom, speeding up the solvent distillation process gently agitates and mixes the contents of the solvent distillation vessel Available Models: MODELS CAPACITY RATE WEIGHT SCR-200 280 L (74G) 76/Lh (20 G/h) 1361 kg (3,000 lbs) SCR-250 450 L (119 G) 106/Lh (28 G/h) 1451 kg (3,200 lbs) SCR-350 768 L (203 G) 161/Lh (43 G/h) 2268 kg (5,000 lbs) SCR-400 1192 L (315 G) 225/Lh (60 G/h) 2585 kg (5,700 lbs) SCR-450 1627 L (430 G) 284/Lh (75 G/h) 2722 kg (6,000 lbs) SCR-550 3051 L (806 G) 435/Lh (115 G/h) 3629 kg (8,000 lbs) Options & Accessories for Your SCR: AutoFill Continuous and automatic operation . Includes Electronic Level Probe, Electric Subpanel, Pneumatic Feed Valve, and 1/2” Stainless Steel Pneumatic Feed Pump Auto Water Control Includes Automatic Pneumatic Water Control Valve and necessary controls (automatically turns water on/off during operation). Reduces water consumption by automatically controlling cooling water flow to the condenser UL or CUL Certification Unit designed to meet UL or CUL specifications. ATEX Certification Unit designed to meet ATEX specifications. Glycol Loop Recirculates the coolant for the distillation unit’s condenser and saves dollars on water and sewer usage. Including Remote Air Cooled Unit with Free Standing Air Coil, Fan with TEFC Motor, Expansion Tank, Circulating Pump, and all necessary Starters and Control Logic. LiquiVac™ Lowers the boiling point of solvent for safety of high boiling solvents. The cooling loop provides for efficient and consistent vacuum. Includes Vacuum Pump, Cooling Tank, Cooling Loop Heat Exchanger, Base, Vacuum Gauge, and Electric Controls. Process Tanks (CST/DST) Clean and Dirty Solvent Tanks (CST/DST) can be incorporated with your recovery unit for a complete closed loop system, allowing for processing of larger volumes of solvent with less operator input. Learn more about process tanks here. Purge Panel Allows for placement of control panel in locations where hazardous materials are processed or used. Available for Class 1 Division 2 as well as NFPA code compliance. Nitrocellulose Safety Package Allows the safe recovery of cleaning solution from nitrocellulose-based inks, required for these applications. Includes AutoFill, Vacuum Sensor, Water Quench, Feed Failure, Low Level Sensor, Audible Alarm. Vacuum Failure Sensor Includes a Digital Vacuum Display and alarms upon loss of vacuum for quick troubleshooting. Mist Eliminator Helps prevent the carryover of solid particulate from the dirty solvent to the distillate to ensure highest possible quality. Foam Suppression Mechanical assembly which breaks up foam that may be created in the distillation process and prevents it from carrying over solids into the clean solvent stream, for solvents with high carryover. Still Bottoms Safety Discharge Package Consists of fixturing to center a drum under the discharge valve, “Drum-in-Place” sensor and drum level sensor. Assures that the drum is in place, centered under the discharge valve, and is not overfilled. The operator cannot discharge the still unless all the sensors are satisfied. The drum level sensor will override the operator’s actions if the drum is full. Auto Sludge Discharge Allows sludge to be automatically discharged to a remote storage tank. Ethernet Communication Network connection to enable remote technical support. Closed-Loop Solvent Recycling Spent solvent collection, distillation, and clean solvent holding. Directly integrated into your process. Our solvent recovery systems are often incorporated into a complete closed-loop solvent management system, utilizing PRI’s specialized and custom-designed Clean and Dirty Solvent Tanks with feeds. In a closed-loop process, waste solvent is collected in a Dirty Solvent Tank, then piped to a Distillation System to separate the contaminants. Then, contaminants are discarded and reusable solvent is automatically sent to a Clean Solvent Tank, which feeds your production process. PRI can engineer solvent management systems to support parts washing, paint lines or other manufacturing processes where solvents are used.
