Hanna BL101 Pool and Spa ORP Controller and Dosing Pump

Description

Hanna BL101 ORP Controller Comprehensive Product Overview

The Hanna BL101 Pool and Spa ORP Controller and Dosing Pump is an advanced yet cost-effective solution specifically engineered for maintaining optimum oxidation-reduction potential (ORP) levels in swimming pools, hot tubs, and spas. ORP is a critical water quality parameter, reflecting the sanitizing power of the disinfectants in the water, most notably chlorine. When ORP exceeds 650 mV, bacteria are typically neutralized in seconds, ensuring user safety and hygiene. The BL101 simplifies the process of keeping water safe by combining precise ORP measurement with automated dosing functionality. Installation involves positioning the HI20083 ORP/Temperature probe and an injection valve in-line with the recirculation system, after which the integrated peristaltic pump doses chemicals proportionally to measured requirements. The system is designed to deliver reliable operation across both domestic and commercial water recreation facilities, making it suitable for pool service professionals, hospitality venues, wellness spas, and high-end private installations. Its robust build and integrated safety systems make it especially appealing for continuous water quality maintenance in critical environments.

Integrated Peristaltic Pump With Stepper Motor

Central to the BL101’s dosing capabilities is the built-in peristaltic pumping mechanism, driven by a stepper motor free of gears or brushes, dramatically reducing mechanical wear and extending service life. This pump technology allows precise chemical dosing without pulsation irregularities and minimizes maintenance interventions. The dosing pump operates with selectable modes: simple ON/OFF control or a refined proportional control mode which dynamically adjusts dosing intensity based on deviation from the ORP set point. The proportional control capability ensures that chemical addition slows as the measured ORP approaches the target, preventing overshooting and stabilizing the system more quickly. Flow rate adjustability between 0.5 and 3.5 liters per hour means that dosing can be scaled for different pool volumes, from smaller private spas to large commercial pools. This intelligent dosing integration improves resource efficiency, reduces chemical waste, and maintains better long-term water balance, critical for operational cost savings and user safety.

Precision ORP And Temperature Measurement System

The BL101 delivers precise measurement capabilities through its HI20083 ORP/Temperature probe, which incorporates both ORP and temperature sensing functions into a single compact PVDF-bodied unit. The platinum-tip electrode ensures superior oxidation-reduction response while resisting corrosion, and the integrated temperature sensor enables automatic temperature compensation across -5.0°C to 105.0°C, enhancing reading accuracy regardless of thermal fluctuations. The ORP range of -2000 to 2000 mV with ±5 mV accuracy at 25°C enables application versatility in different water conditions. Temperature readings are accurate within ±0.5°C, displayed with 0.1°C resolution, and continuously monitored to enhance dosing control stability. A Quick Connect DIN terminal ensures a watertight, low-noise connection to the controller, an essential feature in humid pool environments. Calibration is made user-friendly via single-point process calibration adjustable within ±50 mV of the measured reference value, enabling field adjustments without complex laboratory setups. This level of instrumentation accuracy makes the BL101 suitable for compliance with stringent municipal or institutional water safety regulations.

Advanced Safety Features And Alarm Systems

Safety is integral to the BL101’s design, with multiple alarm configurations that protect against underdosing, overdosing, and operational anomalies. High and low ORP alarms can be enabled or disabled as required, with triggering occurring after sustained consecutive readings outside set thresholds. An overtime protection feature halts dosing if the targeted ORP value is not attained within the user-programmed timeframe (1 to 180 minutes). The alarm relay output (SPDT 2.5A / 230 VAC) allows external devices to be triggered in alarm events, such as auxiliary warning lights or system shutdown signals. The BL101’s multicolored LCD provides immediate visual status cues—green for normal operation, light green when control is disabled, and flashing red during alarms—allowing even non-technical users to instantly understand system status. An optional external input for acid tank level or flow switch ensures dosing ceases if chemical supply runs out or recirculation stops, preventing equipment damage, chemical waste, and unsafe water conditions. Galvanic isolation on these inputs further secures electronics against interference.

Versatile Installation And Mounting Options Available

The BL101 is adaptable to various installation scenarios, with multiple kit configurations to suit different plumbing arrangements. The base BL101-00 pack includes the controller, HI20083 ORP/Temperature probe, test solutions, and power cable—ideal for replacements or retrofits into existing water treatment systems. The BL101-10 in-line mounting kit adds saddles for Ø 50 mm PVC pipe, aspiration and dispensing tubing with injection valves, suited for direct integration into recirculation lines. For more sophisticated setups, the BL101-20 flow-cell mounting kit includes a panel-mounted flow cell assembly and extended tubing lengths for installations requiring precise dosing into controlled flow environments. Each kit comes with certified quality documentation for both the instrument and the probe, ensuring compliance with industry standards. Compact dimensions (90 x 142 x 80 mm) and light weight (910 g) make wall-mounting straightforward, and the IP65-rated casing safeguards electronics against splashes and dust ingress. Whether installed in private spa rooms or municipal aquatic centers, the BL101’s flexible configuration options meet operational needs efficiently.

Targeted Applications For Pool And Spa Management

The Hanna BL101 serves a wide range of applications beyond standard pool disinfection. In commercial spas and wellness facilities, it maintains crystal-clear water and ensures consistent sanitizer potency, enhancing customer satisfaction and safety. In hotel pools, the system reduces downtime by avoiding manual chemical corrections and optimizes chlorine use—all while maintaining compliance with municipal health regulations. Sports complexes and aquatic training centers benefit from its alarm and remote integration capabilities to maintain safe water for high throughput use. The system’s compatibility with proportional control dosing makes it exceptionally efficient for seasonal outdoor pools where chemical demand varies widely. Even in smaller domestic pools, the BL101 simplifies maintenance by automating testing and chemical dosing, allowing owners to focus on enjoyment rather than rigorous upkeep. Featuring precise measurement, easy setup, and minimal maintenance requirements, it proves equally effective in fresh or saltwater chlorination systems.
