Pyxis OxiPanel IK-765 / IK-766 Series Oxidizer Analyzer Panels

The Pyxis OxiPanel family turns the ST-765SS and ST-766SS oxidizer sensors into ready-to-run monitoring panels by pre-mounting and testing them in the factory with a flow reservoir, a display and a data logger. The family has four tiers, the basic IK-765, the auto-brushing IK-765-B, the higher-specification IK-765SS-BP PLUS and the top-level IK-766SS-BPT PLATINUM, plus separate single-parameter panels for ozone and sulfite (IK-765SS-O3, IK-765SS-SO3) and a CPVC dechlorination panel for RO and desalination (IK-765P-DCL). Mikron Proses (Üsküdar, Istanbul) provides application consulting on choosing the tier and the oxidizer format for your water.

IK-765: the basic panel for clean water

The IK-765 pairs an ST-765SS-FCL (free chlorine) or ST-765SS-CLO (chlorine dioxide) sensor with an FR-50 flow reservoir that includes a rotameter and PRV, and a UC-50 micro display and data logger terminal. The oxidizer range is 0.00-5.00 ppm and the precision is ±0.01 mg/L or 1%; sensor response is T95 ≤60 seconds for the oxidizer and T95 ≤5 seconds for pH. The panel measures 590 × 250 × 330 mm and weighs about 5 kg; operating temperature is 4-40 °C on the sensor side and 0-50 °C on the panel side.

IK-765-B: the auto-brushing industrial panel

For demanding waters such as cooling water, food and industrial process water, raw water and treated wastewater, the IK-765-B keeps the electrode clean automatically. It uses the FR-300-PLUS magnetic-coupling motorized brush reservoir instead of the FR-50 (200-800 mL/min, adjustable 100-400 RPM, controlled from the UC-50 over RS-485, with a detergent injection port). The main datasheet covers the FCL-B, CLO-B and Br-B models (same 0.00-5.00 ppm range); DCL-B (free chlorine + sulfite) and NCL-B (monochloramine) models are also offered, with a sulfite range of 0.00-100.00 ppm (auto-range) on the DCL-B and a monochloramine range of 0.0-5.0 ppm on the NCL-B. All B-series panels measure 250 × 590 × 128 mm and weigh about 8 kg.

IK-765SS-BP PLUS: advanced panel with ultrasonic flow control

The BP PLUS series adds closed-loop flow control, through an FS-100 ultrasonic flowmeter and a motorized regulating valve, to the FR-300-PLUS brush reservoir; the display is upgraded to a UC-80 color touch terminal (4.3 or 4.5-inch, depending on the model). Formats are available for free chlorine (FCL), chlorine dioxide (CLO), bromine (Br), total chlorine (TCL), hydrogen peroxide (H2O2), DBNPA, free + total chlorine (TFCL), free chlorine + sulfite (DCL) and peracetic acid (PAA). For most models the oxidizer range and precision are 0.00-5.00 ppm and ±0.01 mg/L or 1%; hydrogen peroxide is different at 0-200 ppm (±0.4 mg/L or 2%) and so is peracetic acid at 0-100 ppm (±0.2 mg/L or 2%). A flow interlock powers the sensor down in AUTO mode when sample flow drops below 50 mL/min. The panel measures 450 × 750 × 180 mm, weighs about 10 kg and runs on 96-260 VAC at 60 W.

IK-766SS-BPT PLATINUM: top-level panel with automatic flushing

The PLATINUM series uses the ST-766SS sensor platform (including pH, ORP and conductivity) and adds to the BP PLUS a fresh-water flush line (programmable auto-flush through a 3-way motorized valve), 110 VAC detergent feed relays and an FR-306-PLUS brush system with a clear chamber. Eight oxidizer formats are available: FCL, CLO, Br, TCL, NCL, PAA, TFCL and DCL. The display is the UC-80-PLUS 7-inch color touch terminal with 6 × 4-20 mA outputs. The panel measures 500 × 800 × 230 mm, weighs about 20 kg and runs on 96-260 VAC at 60 W.

IK-765SS-O3 and IK-765SS-SO3: single-parameter panels

Unlike the BP/BPT families, these two stand-alone panels with a UC-80 display each focus on a single oxidizer or reducing parameter:

• IK-765SS-O3 monitors ozone before bottled water filling and on spring water offload lines. It combines the ST-765SS-O3 sensor with a 316L stainless steel ST-007 flow cell, PRV, rotameter and a digital Hall effect flowmeter. The ozone range is 0.01-2.00 ppm and the recommended flow is 200-400 mL/min.
• IK-765SS-SO3 monitors sulfite (an oxygen scavenger) in RO feedwater and in boiler feedwater and blowdown. It measures 0.00-100.00 ppm with a precision of ±1.0 mg/L or 1%, and is factory-calibrated with sulfite standards prepared in an argon-purged environment. For boiler feedwater and blowdown, the manufacturer requires the panel to be installed downstream of a sample cooler.

Both panels share the same housing size (440 × 350 × 153 mm, about 15 kg) and UC-80 display features.

IK-765P-DCL: CPVC dechlorination panel for RO and desalination

The IK-765P-DCL is a CPVC panel designed to verify chlorine removal before the membrane, so it can be used in both fresh water and sea water (desalination) applications. The ST-765P-DCL sensor measures free or total chlorine (0.001-5.000 mg/L, user selectable) and sulfite (0.001-100.00 mg/L) at the same time, and an FS-100 ultrasonic flowmeter with a motorized valve controls sample flow at 200-800 mL/min. The panel comes with a second, pre-fitted ST-001 (CPVC) tee for an optional ST-500RO PTSA sensor. The manufacturer notes that the total chlorine value is ‘virtual’ total chlorine: it does not include the potassium iodide (KI) injection needed for EPA-compliant ‘true’ total chlorine measurement. The panel measures 600 × 300 × 334 mm and weighs about 10 kg; an NB-IoT card is preinstalled and can be activated on enrollment.

Which tier or which single-parameter panel suits your process depends on the water quality, the fouling load and the number of oxidizers you need to measure. Send us your requirement and we will select the right panel together.
