Acid-Rite 450 pH Adjustment System w/ 1hp Hayward Pump,CSA

The Acid-Rite 450 pH Adjustment System w/ 1.0 HP Hayward Booster Pump (CSA Certified) is an engineered, solid-acid erosion feeder developed by Westlake Water Solutions (Axiall/PPG) for automated pH depression in commercial aquatic facilities.

Designed as a direct alternative to liquid muriatic acid (hydrochloric acid) storage tanks and metering pumps, the Acid-Rite 450 utilizes dry, solid sodium bisulfate ($NaHSO_4$) tablets. It eliminates airborne acid fuming, chemical pump vapor lock, off-gassing degradation of mechanical room equipment, and liquid acid splash hazards while interfacing directly with Pool Link 500/1000 Series pH controllers.

Operating Principle & Controlled Erosion Dynamics

• Controlled Bottom-Layer Dissolution: The dry acid tablets sit inside an upper containment hopper suspended over a calibrated erosion grid plate. Pressurized side-stream water contacts only the bottom layer of tablets. The bulk dry tablets above stay completely dry, preventing tablet slumping, bridging, or erratic concentration spikes.

• Integrated Solution Tank & Float Regulator: Acidic solution ($NaHSO_4$ in water) drains into a lower heavy-duty polyethylene holding reservoir. A mechanical float assembly continuously regulates fresh make-up water volume to maintain the correct solution bath level.

• 1.0 HP Centrifugal Booster Injection: A close-coupled 1.0 HP Hayward commercial centrifugal booster pump draws the dissolved acidic solution from the lower reservoir and injects it downstream into the primary pool filtration return line against prevailing backpressures up to 30 to 40 PSI.

• Safety Float Interlocks: Integrated high-level and low-level magnetic reed float switches protect against equipment room flooding (high-level water cutoff) and prevent dry-run pump mechanical seal burnout (low-level motor interlock).

Technical Specifications

• Tablet Hopper Capacity: 45 lbs (20.4 kg) dry sodium bisulfate tablets.

• Acid Delivery Capacity: Delivers the acid-neutralizing equivalent of up to 4.5 to 5.0 gallons of 31.45% muriatic acid per hour (approx. 9.5 to 10.5 lbs/hr of equivalent dry acid delivery).

• Facility Sizing Guidelines:

  • Commercial Competition Pools / Natatoriums: Up to 400,000 to 500,000 US Gallons (approx. 1,514,000 to 1,892,000 L).

  • Outdoor Waterparks & High-Load Bather Pools: Sized for pools up to 150,000 to 250,000 US Gallons (approx. 568,000 to 946,000 L) depending on turnover rate and chlorine source alkalinity.

• Booster Pump Specification: 1.0 HP Hayward Centrifugal Pump (commercial closed-impeller wet end, continuous-duty motor).

• Hydraulic Connections:

  • Inlet (Water Supply): 1" Schedule 80 PVC Slip / Socket (regulated incoming supply: 15 to 20 PSI).

  • Outlet (Discharge/Injection): 1" Schedule 80 PVC Slip / Socket with included union check valve and manual throttling valve.

• Electrical Specifications & Approvals:

  • Primary Power Supply: 120V AC, 60 Hz, 1-Phase, 15 to 20 Amp dedicated circuit.

  • External Controller Interface: 120V AC switched trigger from Pool Link 500/1000 Series pH feed relays.

  • Certifications: CSA Certified, NSF/ANSI Standard 50 commercial listed.

• Overall Dimensions: Approximately 27.5" W × 20.0" D × 38.0" H (approx. 70 cm W × 51 cm D × 96.5 cm H).

Consumable Tablet Specification

• Specified Chemical: Acid-Rite Sodium Bisulfate Tablets (engineered solid $NaHSO_4$ tablet formulation).

• Chemical Handling Safety: Eliminates hydrochloric acid gas ($HCl$) that corrodes nearby electrical switchgear, pump motors, and metal structures in mechanical rooms.

• Critical Chemical Safety Mandate: Never cross-contaminate or mix with chlorine. Acid-Rite hoppers must exclusively receive sodium bisulfate tablets. Accidental loading of calcium hypochlorite (Accu-Tab) or trichlor tablets will trigger violent exothermic decomposition, lethal chlorine gas release, and explosion hazards.

Weight and Logistics Profile

• Net Unit Dry Weight: Approximately 95 to 110 lbs (approx. 43.1 to 49.9 kg), including hopper, tank, piping assembly, and the 1.0 HP Hayward pump.

• Palletized Shipping Weight: Approximately 155 to 175 lbs (approx. 70.3 to 79.4 kg), including custom pallet, protective corrugated crating, and boxed installation valves.

• Shipping Dimensions (Palletized): Approximately 36" L × 32" W × 45" H.

• Freight Classification: Ships via LTL Motor Freight (Class 150 to 200).
