4610--WATER PURIFICATION SYSTEM HAMPTON VAMC/DIALYSIS 36C24626Q0335
Summary
AI-generated · Feb 10, 2026Hampton VAMC requires a water purification system capable of producing at least 200 liters per hour, model MEDICA-R 200, with deionization capability and installation, commissioning, and training included. The unit must support a makeup rate of 200 L/hr at 15°C, provide a maximum delivery flow of 21 L/min at 45 psi (115V, 60 Hz), and meet stringent water quality targets (inorganics resistivity >10 MΩ·cm, TOC typically <30 ppb with notes up to 500 ppb, bacteria <10 CFU/mL, silica <0.05 mg/L, and 0.2 µm particulates). An ion-exchange cylinder (Nuclear or Hypex grade resin) must be installed, and the system should accommodate the specified pretreatment and feedwater requirements, including wall-mountable housing and the必要 filters as needed.
Feedwater must come from tap water with conductivity <1000 S/cm, with pretreatment requirements including calcium as CaCO3 <250 ppm (or softening/low RO recovery if higher), free chlorine and chloramine kept below 0.1 ppm (with appropriate carbon treatments), silica and fouling index controls, iron/manganese <0.05 ppm (with possible back-washable Fe filtration if necessary), and TOC <2 ppm C (with staged carbon filtration for higher TOC). The system should operate from water at 4–40°C, achieve 20 L/min at 15°C, allow a 45 L/min drain, and tolerate feedwater pressure up to 60 psi (min 30 psi). Use ELGA components LA683 (Filter Housing) and LC172 (Carbon Filter), ensure wall-mount filtration compatibility, and provide a floor footprint of roughly 4 ft by 6 ft with a 3" floor drain meeting code. Electrical requirements are 115V, 60 Hz input with a 24V DC control voltage, up to 2000 VA, and noise under 70 dBA; overall dimensions are about 32" W x 35" D x 72" H.
