Hayward | HYR400L4 | HydroRite UV, Crypto, 333GPM
The Hayward HYR400L4 HydroRite UV Crypto system is a high capacity commercial sanitization solution engineered to provide advanced supplemental and secondary disinfection, including enhanced protection against chlorine resistant microorganisms such as Cryptosporidium. Designed for flow rates up to 333 gallons per minute, HydroRite UV combines dual wavelength ultraviolet technology with hydroxyl radical generation to deliver powerful oxidation and sterilization. By significantly reducing chloramines and lowering chemical demand, the HYR400L4 improves indoor air quality, boosts swimmer comfort, and enhances overall water clarity in demanding aquatic environments.
Key Features
⢠Provides supplemental and secondary disinfection per CDC Model Aquatic Health Code recommendations, including enhanced Crypto mitigation
⢠Reduces chloramines by 50 percent or more, improving indoor air quality and swimmer comfort
⢠Lowers chemical demand by 50 percent or more, reducing operational costs and extending salt cell and equipment life
⢠Dual wavelength low pressure UV bulbs generate hydroxyl radicals for powerful disinfection with minimal impact on chlorine residuals
⢠Lightweight Schedule 80 PVC and 316L stainless steel construction ensures durability, corrosion resistance, and simplified installation
⢠Plug and play design with intuitive controls and 120V input for easy setup and energy efficient operation
⢠Long life UV lamps rated for 13,000 hours, offering more than double the lifespan of many medium pressure systems
Product Overview
The Hayward HYR400L4 HydroRite UV Crypto system delivers advanced ultraviolet sanitization and oxidation performance specifically engineered for commercial pools needing enhanced protection against chlorine resistant pathogens. The dual wavelength UV technology generates hydroxyl radicals that destroy microorganisms with remarkable efficiency, making this system ideal for indoor pools, waterparks, competitive swim venues, and municipal facilities with high bather loads.
By dramatically reducing chloramine formation, the HYR400L4 improves air quality and greatly enhances swimmer comfort, while lowering chemical use and operational expenses. Its rugged PVC and stainless steel construction supports long term reliability, and the intuitive plug and play setup simplifies both installation and daily operation. Backed by NSF 50 certification and an exceptionally long lamp life, the HYR400L4 stands out as one of the most sophisticated, effective, and energy efficient sanitization systems available for large commercial aquatic facilities.
