Hydro Instruments has been manufacturing highest quality equipment for the water treatment industry since 1978. We manufacture a complete line of vacuum solution feed and related equipment for Chlorine, Sulfur Dioxide, Carbon Dioxide, and Ammonia. We have also been producing vacuum feed equipment for a variety of liquid chemical solutions since 2000. From the beginning, Hydro Instruments has focused on producing the most durable equipment on the market. Our equipment is constructed by machining (rather than injection molding) the finest materials available for each application.

Hydro Instruments' gas chlorination equipment is absolutely the best on the market. What sets us apart from ALL of our competitors is that: We take great care in assembly and testing to make certain all products are in perfect working order.

• We stock all products and parts for immediate shipment.
• We machine all of our parts from solid stock of the finest materials available. Our body parts are machined from PVC stock. Our body parts will not crack or warp. This prevents leaks and greatly reduces repair costs. Our competitors have cut cost and compromised durability by using injection molding.
• Our material selection and construction is designed for maximum durability and corrosion resistance. Inlet capsules are solid Hastelloy-C276 or PVDF, inlet valves & rate valves are solid Silver.
• Hydro offers the finest inlet filter available for up to 100 PPD (2 kg/hr) feed rates. This plug type, porous PTFE (Teflon) filter offers maximum protection from venting caused by impurities and particles.
• Our vacuum regulators have the fewest parts. Count them. 58 to 64 depending on the model.
