Vapor Compression Stills

Product catalog summary

Overview: The Mueller VaPure® Vapor Compression Stills are designed to produce high-purity distilled water by boiling softened feedwater and condensing the steam. This system is highly efficient, requiring no external steam source, coolant, or filtering membranes, and is cost-effective compared to reverse osmosis and conventional distillation processes.

Specifications: The system includes a plate heat exchanger, feedwater degasser, evaporator/condenser, compressor, and distillate degasser. It is available in capacities of 25 GPH, 200 GPH, and 1,000 GPH, suitable for various pretreated feedwater sources such as tap, deionized, and brackish water.

Features and Benefits: The VaPure stills are energy-efficient, using heat recovery to preheat feedwater, and are six to ten times more efficient than conventional thermal stills. They meet or exceed industry standards like EPA, FDA, and WQA, and feature a simple, automatic control system that reduces maintenance costs.

Optional Equipment: Accessories include filters (water, carbon, media), pumps, softeners, and parts kits.

Industrial Applications: Suitable for bottled water production, utilities, and clinical and analytical applications.

Performance and Standards: The system ensures chemically and biologically pure distillate with no detectable bacteria, pyrogens, or organics. It operates within a pH range of 5.0–9.0 and maintains a maximum of 1.0 ppm total dissolved solids.

Technical Data: The system's components are made from high-quality materials like 316 stainless steel and titanium. It operates at various voltages and frequencies, with power consumption ranging from 1.5 kW to 50 kW depending on the model.

Physical Dimensions: The dimensions and weight vary by model, with the largest model (VCS-1000) measuring 101 inches in height and weighing 6,900 lbs when operating.

MUELLER® VAPURE® VAPOR COMPRESSION STILLS The VaPure vapor compression still boils softened feedwater and condenses the steam to produce pure distilled water. It is the most cost-effective system available for producing high-purity water, yielding up to 1,000 GPH with no external steam source, or coolant, and no filtering membranes or resins. The VaPure still consistently outperforms reverse osmosis, deionization, and conventional distillation processes and costs less to maintain. It produces chemically and biologically pure distillate that meets or exceeds industry standards, including EPA,...
