Nextreme™ Eco-Friendly Chiller

The Nextreme™ Eco-Friendly Chiller offers all users a cost-effective and reliable thermal management solution that is compliant with foreseeable future regulations with regards to refrigerant use. Part of the Nextreme family of chiller products, the EFC line offers the same ease of use, low maintenance features that makes it ideal for cooling sensitive electronics in industrial and analytical equipment. By using natural R290 refrigerant, the EFC Chillers achieve similar performance with a near-zero Global Warming Potential (GWP) when compared to traditional hydrofluorocarbon (HFC) refrigerants. The product also uses a variable speed compressor to maintain a high coefficient of performance (COP) and reduce system noise during partial load operation. For OEMs, the Eco-Friendly Chiller can be configured to meet unique application requirements. Units run on universal input of 200-240V, 50/60Hz, which means that they can operate anywhere in the world.

Standard Features

Color Touch Screen Display
Simple user interface and detailed communication of system status without the need for alarm codes or symbols.
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.

Accessory Kits

Feature
Kit Part Number
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.
