Nextreme™ Performance Chiller
The Nextreme NRC2400 Recirculating Chiller features premium components and environmentally friendly refrigerants in a user-friendly design. It is designed to cool well below ambient and dissipate heat away from thermally sensitive equipment. Featuring variable speed motors for the compressor and condensing fan, the Nextreme NRC2400 offers a high coefficient of performance and low-noise operation. The Nextreme NRC2400 comes with several standard features and additional options allow for application-specific configurations. Power cord is not supplied with the unit and must be ordered separately.
Features
  • Precise Temperature Control
  • Compact Form Factor
  • Reliable Solid-State Operation
  • Intuitive GUI
  • Low Noise Operation

Standard Features
Variable Speed Motors
Variable speed compressor and condensing fans for quiet operation and improved energy efficiency.
Semi-Closed Fluid System
Sealed fluid system with breathable reservoir cap (similar to an automobile). This prevents evaporative loses, introduction of bacteria, and the need for components to prevent fluid from draining back into the system when installed below the application.
Optical Fluid Level Switch
Fluid level sensing with no moving parts.
RS-232 Communications
Complete control integration of chiller into higher level assembly control system.
Supply Pressure Sensing
Pressure sensing for applications sensitive to high operating conditions.

Description
Flow Control Valve and Flow Sensing Kit
387004277
Externally installed valve for reducing the overall flow to the application. Full flow continues through the chiller to maintain high heat transfer rates and temperature stability. Flow meter for measuring coolant flow rate. Installed external to the chiller with both a local display and connectivity to chiller LCD display.
Water Filter Kit
387004279
Hot swappable, 5-micron water filter for filtering particulates from the coolant circuit.
