2 Why Water Saver? he new Water Saver from Nortec is your most efficient combatant against the rising energy costs. his closedloop cooling system is self contained and is designed to remove heat from water cooled machinery. t can very efficiently cool the fluid to temperatures slightly above the ambient. Operating rinciple dvantages Quick and easy installation and commissioning esigned and manufactured to suit your application losedloop system eliminates the possibility of corrosion and contamination Requires little or no maintenance onsistent temperatures enhances process efficiency Saves $$ no more city water/sewer recurring costs ypical process cooling fluid (water with varying proportions of glycol) is circulated through the closed loop system by using pumps. mbient air is sucked from the bottom of the Water Saver. his results in a steady flow of air around the tubes carrying the cooling fluid. With the use of thermally activated valve (optional) and an additional trimcooler, temperatures very close to ambient and below can be achieved. ool Water Out ot Water n qua ool ypass (Optional) irooled Water Saver ity Water nlet Optional rim ooler and ontrols ity Water Outlet xpansion ank ump djustable igh ressure ypass Valve ypical Water Saver with Optional umping station and rim cooler Standard eatures: Vertical/orizontal ir ischarge onfiguration alvanized Steel rame and asing urable luminum asing luminum ins Mechanically xpanded into opper ubes 6 pole, 30/4V, Single/hree hase, O an Motors ully affled an Sections NM 3R Suitable for Outdoor nstallation an Motor Starter an Motor using lose oupled entrifugal ump (Optional) repiped, actory ssembled and ested ll Nortec Water Saver are designed for vertical airflow.

Optional voltages are also available upon request. utodual controller he universal pump controller incorporates the latest in electronic technology in a compact and userfriendly enclosure. he controller is independent of the pump size. he failsize design ensures that the pumping station will operate at the maximum level of efficiency. With its monitoring capability, it enables equal running time of the pumps. his makes it convenient to schedule maintenance activities.

(low rates up to 500 M and head pressure up to 1 feet). he double pump setup is mounted on a heavy skid with a separate regulating valve for each pump. he pump setup come with an isolation valve and maintenance activities can be carried out without shutting down the system. Nortec umping stations are equipped with your choice of NM enclosures. Optional control and monitoring indicators can be added along with state of the art controllers. ontroller igh fficiency rim ooler 3 way hermostatic Valve Optional state of the art controllers are used for optimizing the performance of the pumping stations. he s (rogrammable ogic ontrollers) are designed with easeofuse in mind. heir modular and versatile features make it suitable for your applications including local and remote display. Optional connections are also available. he trim coolers are mounted inline with counter flow and are typically shell and tube or plate type. t monitors the outlet temperature and with its optional autoregulating feature and ensures consistent inlet temperature to the heat source. dditionally it has bleed and drain valves for maintenance purposes. hese modulating thermal valves are designed to bypass around coolers during startup and then provide accurate temperature control for cooling systems during normal operation. hey do not require any outside control to operate.
