Industrial ultra-pure water purification unit Puridest PD 12 R

laboratory

Product overview
LAUDA Puridest stills require no specialist for commissioning or maintenance and accept a wide range of feed waters. Ultra-pure water is produced at the push of a button. Designed for laboratory and industrial bench or wall mounting, the unit combines automatic operation with accessible maintenance features.

Features

• Water still for single distillation, fully automatic, with storage tank; bench or wall mounting
• Condenser (cooling coil) located inside the storage tank and easily exchangeable
• Automatic water cut-off to avoid unnecessary water consumption
• Electronic contamination monitoring with automatic distillation stop and visual cleaning instruction
• Heating element, evaporator, storage tank and condenser made of stainless steel
• Storage tank capacity equals twice the hourly production
• Solenoid valve for controlled water supply
• Evaporator easily accessible for cleaning
• Automatic refill of the storage tank after distillate removal via electronic level detection
• Housing made of galvanised sheet steel with powder coating; double-walled design
• Distillate withdrawal via drain cock with continuous and touch positions
• Energy-efficient: distillation uses preheated cooling water
• CO2 degassing via condenser outlet
• Thermostatic low-water cut-off for dry-run protection
