Acid-Rite 2500 pH Adjustment System w/ 1hp Hayward Pump,CSA

The Acid-Rite 2500 pH Adjustment System w/ 1.0 HP Hayward Booster Pump (CSA Certified) is an industrial-capacity, solid-acid erosion feed system engineered by Westlake Water Solutions (Axiall/PPG) for automated pH depression in high-demand commercial aquatic centers, municipal waterparks, competition natatoriums, and resort surf lagoons.

Equipped with an expanded 250 lb dry-acid hopper (more than five times the capacity of the Acid-Rite 450), an integrated solution reservoir, and a dedicated 1.0 HP Hayward commercial centrifugal booster pump, the 2500 is engineered to maintain target water pH and total alkalinity under heavy bather loads. By using engineered dry sodium bisulfate ($NaHSO_4$) tablets, it completely eliminates liquid muriatic acid carboy handling, off-gassing room corrosion, peristaltic tube fatigue, and chemical pump vapor lock.

Operating Principle & Controlled Erosion Dynamics

• Controlled Bottom-Layer Dissolution: The 250 lb tablet load is supported above an engineered multi-port erosion grid. Make-up water delivered by the internal float assembly contacts only the bottom layer of tablets. The large dry column above stays completely dry and isolated, preventing tablet wicking, softening, clumping, bridging, or chemical concentration surges.

• Continuous Solution Mixing Basin: Acidic liquid ($NaHSO_4$ dissolved in pool water) drains continuously by gravity through the erosion grid into an integrated, heavy-duty polyethylene holding reservoir equipped with internal baffling to stabilize dissolved concentration.

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

• Safety Float Interlocks: Pre-wired with dual high-level and low-level magnetic reed float switches connected to an internal motor contactor. The system isolates incoming water on high level (preventing mechanical room flooding) and cuts power to the booster pump on low level (preventing dry-run pump mechanical seal burnout).

Technical Specifications

• Tablet Hopper Capacity: 250 lbs (113.4 kg) dry sodium bisulfate tablets.

• Acid Delivery Capacity: Delivers the acid-neutralizing equivalent of up to 18.0 to 20.0 gallons of 31.45% muriatic acid per hour (approx. 40 to 45 lbs/hr of equivalent dry acid delivery).

• Facility Sizing Guidelines:

  • Commercial Aquatic Centers / Natatoriums: Up to 1,500,000 to 2,000,000+ US Gallons (approx. 5,680,000 to 7,570,000 L).

  • Outdoor Waterparks & Wave Pools: Up to 600,000 to 800,000 US Gallons (approx. 2,270,000 to 3,028,000 L) under peak bather loads and aeration conditions.

• 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, manual flow throttling valve, and inline flow indicator.

• 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 34.0" W × 26.0" D × 55.0" H (approx. 86.4 cm W × 66.0 cm D × 139.7 cm H).

Consumable Tablet Specification

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

• Mechanical Room Protection: Eliminates ambient hydrochloric acid vapor ($HCl$), safeguarding sensitive mechanical room electronics, chillers, dehumidification ductwork, and structural metals from corrosive degradation.

• Critical Chemical Safety Mandate: Never cross-contaminate or mix with chlorine. The Acid-Rite 2500 hopper must exclusively receive sodium bisulfate tablets. Accidental loading of calcium hypochlorite (Accu-Tab), trichlor, or dichlor tablets will trigger violent exothermic decomposition, lethal toxic gas generation, and catastrophic explosion risk.

Weight and Logistics Profile

• • Net Unit Dry Weight: Approximately 150 to 170 lbs (approx. 68.0 to 77.1 kg), including the 250 lb hopper structure, mixing tank, PVC manifold, and the 1.0 HP Hayward pump.

  • Palletized Shipping Weight: Approximately 215 to 240 lbs (approx. 97.5 to 108.9 kg), including heavy-duty pallet, reinforced corrugated crate, banding, and boxed installation accessories.

  • Shipping Dimensions (Palletized): Approximately 42" L × 36" W × 62" H (approx. 107 cm × 91 cm × 157 cm).

  • Freight Classification: Ships via LTL Motor Freight (Class 150 to 200). Liftgate or loading dock required for unloading.
