Reducing costs and water consumption makes good business sense and is the responsible thing to do.
Many manufacturers and equipment users turn to recirculating water chillers as a cost-effective and earth-friendly way to simultaneously dissipate heat and conserve water.
Unlike single pass systems which use water (often city water) to pass through a heat exchanger or directly cool and then dump the water after a single use, recirculating systems use a chiller to chill the same fluid in a continuous loop. These closed-loop systems offer a number of benefits.
In addition to saving money by reducing water and sewer usage costs, recirculating water chillers also increase process uptime and reliability and improve the overall cost of ownership. The savings can even provide a quick return on the chiller and process investment.
Reduced Consumption and Contamination
A properly designed closed-loop cooling system using a water chiller can cut water usage to virtually zero. Once the closed-loop system is filled, only a minuscule amount of make-up water is required to replenish what is lost during tooling changeovers – typically only a few gallons a year. This results in significant water savings compared to using on-demand city water for cooling.
The completely closed loop system eliminates environmental contaminants from entering the operation preventing impurities and pollutants from damaging equipment or reducing the effectiveness of a given process. Coolants kept at an optimal temperature offer a longer service life as a result of slower break down speeds and a significant reduction in bacteria growth.
Reduced Disposal Processes and Cost
Reusing water and cooling fluids enables companies to comply with wastewater restrictions and significantly reduce water and sewer costs.
Beyond the mere cost to dispose of used water and effluent, the exact makeup of fluid discharged can affect sewer costs. Depending on municipal regulations, waste water may need to be treated in-house prior to entering the sewer system, causing additional processing and handling costs which could be reduced or avoided by recirculating water and fluid coolants.
Permits and testing to evaluate discharged industrial water can cost a company directly or indirectly in the form of in-house processes and reporting or increased taxes and fees from local municipalities monitoring the environmental impact of wastewater.
The purchase of a closed-loop cooling system can pay for itself over time by reducing the amount of wastewater generated and subsequent disposal.
Increased Uptime and Precise Temperature Control
Closed-loop cooling systems are often used with spindles, EDM equipment, lasers, and plastic and rubber molding machines. A properly designed system provides these machines and many more with the ability to maintain constant coolant temperature as well as precise temperature control for the equipment it supports resulting in closer production tolerance and fewer maintenance costs.
Using a closed-loop cooling system designed for a given process application and temperature demands will improve the efficiency of the entire process. The ability to maintain precise temperature control will protect the operations of the equipment and allow for steady use and reliable results.
Improved Total Cost of Ownership
The purchase of a closed-loop cooling system can pay for itself over time by reducing operating costs and increasing uptime and efficiency. With proper planning, the integration of a recirculating chiller can significantly reduce or eliminate costly downtime.
Savings in the form of less water consumption and sewer costs compound also decrease the total cost of ownership when a closed-loop chiller is utilized.
A closed-loop chiller from Glen Dimplex Thermal Solutions (GDTS) eliminates water waste by re-circulating your process water through the system. In addition to the benefits provided by all GDTS equipment, these chillers provide water-saving solutions for a variety of industrial applications.
