800 light commercial reverse osmosis system  

TSM series of commercial Reverse Osmosis water purifiers built to suit the needs and requirements of commercial pure water users.
This includes restaurants, coffee stores, convenience stores, microbreweries, supermarket produce and food preparation operations, misting and humidification systems, car wash facilities, and many other businesses that must have consistent high quality water for their daily operations. The key factors of reliability, serviceability, and consistent performance with minimum user intervention are achieved in the solid design of the TSM systems. Stainless steel is used throughout; in frame, pressure vessels and fastening hardware to provide the structural strength and corrosion resistance appropriate for a commercial appliance.

The TSM system design is optimized for either shelf mount or wall mount installation. The four models; 400 GPD, 800 GPD, 1200 GPD and 1500 GPD all occupy the same very compact footprint. This allows flexibility in accommodating the limited space available in most commercial utility equipment locations. Quick connect tube fittings on all system ports further simplifies installation and service. Most important, all TSM models incorporate the most reliable combination of proven reverse osmosis hydraulic design and state of the art Thin Film membrane elements to provide the long term performance expected by commercial users.

*New Blending Option - The basic configuration of the TSM series products is ideal for many typical water purification applications. However, there are certain users such as craft/microbreweries, labs, manufacturing, home use, and premium coffee houses that often desire the ability to monitor and control the TDS level of the output purified water. This option is available on TSM-400 to 1500 systems. The Blend option includes a digital TDS monitor and a metering needle valve. This option allows a precise amount of filtered feed water to be added (blended) to the product water flow and the blended TDS level is displayed on the monitor readout *Required: Please mention that you would like to add the FREE "Blending Option" at the time of ordering.
All Systems Wet Tested Before Shipping
