UTILITIES
Total system cooling water power dissipation (50 or 60 Hz) — see available recirculating chillers 8604: 4250 W
8607: 13400 kW

Note: chiller power specifications listed are for 100% duty cycle. Many common magnet testing applications such as hysteresis loops will not require as much cooling power. Please consult Lake Shore for chiller recommendations for your specific applications.
