Model D2 Mega-Pure Deionizer System (3923J40)
- For removing ionized materials from feedwater by means of ion exchange cartridge; an adsorption type cartridge can also be used to remove organic materials (bacteria and pyrogens are not removed)
- Cartridge replacement is simple and fast
- Flow rate (19 liters per hour maximum) can be adjusted by stainless steel needle valve
- Additional valve is provided for turning water source on and off
- Automatic temperature-compensated purity monitor is set to 50,000 ohm-cm
- Pilot light on front panel indicates whether water purity drops below 50,000 ohm-cm
- Additional front panel controls include knob for selecting “normal” or “purge” operating mode and knob for adjusting flow rate
- Double cartridge unit allows use of organic and inorganic cartridges simultaneously, or use of two ion exchange cartridges in series
- Housing is epoxy-coated metal with keyholes on back to permit wall mounting
- Includes 1.5 m length of 1/4-inch-o.d., high-pressure, polypropylene hose for connection to water supply and 1.2 m length of 5/16-inch-bore vinyl tubing for attachment to outlet
- Available adapter allows connection to a compact still
With 3-wire cord and plug for 120 V, 50 or 60 Hz; current draw less than 0.1 ampere; without deionizer cartridges. Overall dimensions: 22 1/2 x 7 1/2 x 22 1/2 inches; operating weight 18.6 kg.
Accessories (3923J88 and J92)
- 3923J88 Solenoid Valve Accessory is for the Model D2 Deionizer (Thomas number 3923J40) when it is used as a stand-alone system
- 3923J92 Still Adapter Kit connects Models MP-3A (3915L41) and MP-6A (3915M50) Water Stills to the MEGA-PURE deionizer for automatic operation; required for use with pretreated feedwater
High Purity Replacement Cartridges (3923K25)
- Capacity 1,370 grains (89 grams) of calcium carbonate or 1,600 grains (104 grams) of sodium chloride; equivalent to mineral content of 290 liters of water with hardness of 180 ppm
- Typical product resistivity 2,000,000 ohm-cm, pH 6.8-7.2
- Borosilicate glass, 406 mm long x 102 mm diameter, with vinyl plastic end caps
High Capacity Replacement Cartridges (3923K32)
Similar to the high-purity type, but has increased capacity of 2,400 grains (156 grams) of calcium carbonate, or 2,810 grains (182 grams) of sodium chloride. Typical product resistivity 350,000 ohm-cm.
Organic Removal Replacement Cartridge (3923K56)
- Adsorber type removes free chlorine and various organic impurities (no bacteria or pyrogens)
- Service life with tap water is several times that of ion removal cartridges
Borosilicate glass, 16” L x 4” diameter, with vinyl plastic end caps.
