operation and control of flow, temperature and pressure. They are two-component systems utilizing a compact pump package and a remote, air-cooled heat exchanger. The system is filled with a low-cost water/glycol coolant mixture, which is continuously circulated under pressure through the process or machine. The operation is so simple, no assigned operator is needed. The pumps, heat exchanger and control package regulate temperature, flow rates and heat exchange using a fixed amount of coolant indefinitely. Because it is a self-contained system, you won't need to add or change water or glycol.
Clean System
As a closed-loop system, the HydroThrift CD unit operates cleanly. There's no entrained air, contaminants, air-borne dirt or chemicals from water treatment as in an open type or "once-through" water system. Service life of production equipment can be greatly increased by preventing scaling, liming and corrosion on coils, water jackets and heat exchangers. And because the water/glycol mixture is recirculated, there is no discharged water, which means you avoid water use regulations and sewer charges.
Low Maintenance
Continuous, high efficiency operation cuts maintenance costs and downtime. Eliminating scale and dirt build-up on heat exchanger and water jacket surfaces results in high-efficiency operation. Constant control of the flow, temperature and pressure minimizes the costly inconsistencies found in external "once-through" water cooling.
Easy Installation
HydroThrift CD cooling systems are compact and simple to install. The pump and control unit is delivered to you skid-mounted, prepiped and prewired with built-in temperature controls. On-site, simply mount the main heat exchanger where it will have an adequate supply of clean ambient air and locate the pumps anywhere between the heat load and the heat exchanger. Connect the piping and wiring and add the coolant. The surge tank provides easy access for filling the system. HydroThrift CD cooling systems provide continuous, high-efficiency heat transfer at less the initial cost and with better payback than other cooling systems.
