Chemical delivery is how sanitizer and pH chemicals physically reach the water once the controller calls for them. The delivery method shapes daily operations: how chemicals are stored, how often they are delivered, how much staff handle, and how well the system keeps up at peak demand.
Commercial pools in New York mostly use liquid sodium hypochlorite through metering pumps, calcium hypochlorite through erosion feeders, or, less often now, gas chlorine or on-site salt generation. Trichlor tablets add cyanuric acid, which the State prohibits in public pools. FreyTech's role is to size delivery to measured demand and to install it with the interlocks, storage, and training the method requires. Alongside Pulsar calcium hypochlorite feeders, FreyTech represents WAPOTECH's WAPO Chlor on-site sodium hypochlorite electrolysis systems.

Selection considerations
Daily chlorine use, peak bather load, temperature, and exposure determine capacity. Brochure gallonage is a starting point at best.
Dry oxidizers need segregated, ventilated storage and a loading routine; liquids need containment and delivery access.
Calcium hypochlorite adds calcium hardness; sodium hypochlorite raises pH and TDS. Plan pH control and water replacement accordingly.
Every feeder should be switched by a controller with flow interlock and failsafe limits.
Feed-equipment changes may need engineer-prepared plans and health-department approval (6-1.8).
Featured and available products
Products FreyTech can help you evaluate, and where documented, install and service. Featured items appear first; availability language is shown on each card.
FeaturedPatented high-capacity erosion feeder for calcium hypochlorite briquettes; manufacturer-rated for 500,000 to 1,000,000+ gallon pools; up to 189 lb/day available chlorine.
Available through FreyTech
Best fit: Competition venues, Municipal aquatic centers, Waterparks
BECS Technology CO2 feed system in 5–50 and 20–200 SCFH sizes with diffuser or Venturi eductor; NSF/ANSI 50 listed per BECS.
Available through FreyTech
Best fit: Institutional pools with BECSys controllers, Therapy pools where acid storage is a concern
CHLOR SM is ChlorKing's in-line salt chlorinator for commercial pools: a mild saline pool is passed through an electrolytic cell that makes chlorine on site, so there is no chlorine delivery or storage.
Request availability
Best fit: Saline conversion of indoor and outdoor commercial pools, Hotel, club and community pools, Therapy pools where bather comfort matters
NEXGEN makes a pH-balanced sodium hypochlorite solution on site from a brine tank and pool water, so the pool itself is not converted to saline and no chlorine is delivered or stored.
Request availability
Best fit: Multi-pool aquatic centers, Water parks with high chlorine demand, Facilities eliminating bulk sodium hypochlorite storage
Pulsar Infinity is an erosion-style feeder that dissolves Pulsar's slow-dissolving calcium hypochlorite tablets into a chlorine solution for pools from roughly 5,000 to 150,000 gallons.
Available through FreyTech
Best fit: Small and mid-size indoor pools, Hotel and community pools converting from liquid bleach, Spas and therapy pools within the sizing range
Flow-based erosion feeder with a 30 lb hopper; 2–36 lb/day available chlorine; manufacturer-recommended pool size 10,000–300,000 gallons.
Available through FreyTech
Best fit: Mid-size lap pools, Hotel and resort pools, Camp and seasonal pools
Stenner's Classic Series is a peristaltic metering pump: the chemical moves through a replaceable tube squeezed by rollers, so it never touches the pump mechanism and the pump can run dry or handle off-gassing bleach without losing prime.
Request availability
Best fit: Sodium hypochlorite feed, Muriatic acid feed, Controller-switched or pressure-switch-activated dosing
The EasyCarb 750 (Pool) is a permanently installed, low-pressure bulk CO2 cylinder that replaces banks of high-pressure gas cylinders for pool pH control.
Request availability
Best fit: CO2 supply for pH control at large indoor pools, Facilities replacing muriatic acid with CO2, Multi-pool centers with steady CO2 demand
WAPO Chlor systems generate a 0.6 percent sodium hypochlorite solution on demand from diluted brine and electricity, replacing delivered liquid chlorine or calcium hypochlorite. Factory pre-assembled Compact and PRO series units cover roughly 30 to 8,500 g/h of chlorine equivalent.
Available through FreyTech
Best fit: Municipal indoor and outdoor pools, Hotel and resort pools and spas, Cooling towers and cleaning-in-place disinfection

An automated controller is the decision-maker in the equipment room.
Controllers and feeders are only as good as their consumables: probes, flow-cell parts, pump tubes, feeder nozzles, and the chemical itself.
New York requires manual testing of pH and free and total chlorine at the beginning, during, and end of each swimming period with a DPD kit and fresh reagents (10 NYCRR 6-1.11).
Technical resources
No. Many pools are well served by properly controlled liquid feed. We compare approaches with the facility's own chemical use, labor, delivery, and storage facts.
Trichlor tablets add cyanuric acid, which 10 NYCRR 6-1.11 prohibits in public pools.
Next step
Send pool volumes, current disinfection method, and daily chlorine use if you have it. We will tell you which delivery approach fits and what storage it needs.
