Alphacool ES Chiller 700 Active Water Cooling Unit 700W G1/4 inch Black 13087

The Alphacool ES Chiller 700 stands apart from conventional water cooling by integrating active refrigeration directly into the loop. Instead of relying on ambient air to dissipate heat, it uses a rotary compressor and R134a refrigerant to hold coolant temperatures at a precise setpoint, even under sustained 700 W thermal loads. This makes it a true chiller, not just another radiator.

Highlights

• 700 W cooling capacity at 25 °C ambient and 25 °C water temperature
• Integrated microcomputer PID control with digital LED display
• Adjustable temperature range from 5 °C to 35 °C
• Built-in 3.5 liter reservoir and 10 L/min pump with 10 m head
• G1/4" connections for standard water cooling fittings
• Multiple safety protections: flow alarm, high/low temp alarm, compressor delay, overcurrent

In daily use

The ES Chiller 700 is built for continuous operation in test benches, server environments, or high-performance workstations where stable coolant temperatures are critical. Its rotary compressor and R134a charge of 200 g deliver reliable cooling, while the microcomputer PID controller maintains the selected temperature with minimal fluctuation. The front digital LED display provides real-time status and easy adjustment. The integrated pump pushes up to 10 liters per minute through the 3.5 liter reservoir, ensuring consistent flow across the entire loop. With a noise level below 50 dB(A), it remains unobtrusive in most settings.
