## 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.

Description

Flow Control Valve and Flow Sensing Kit

387004277

This externally installed valve is for reducing the overall flow to the application. Full flow continues through the chiller to maintain high heat transfer rates and temperature stability. The flow meter is for measuring coolant flow rate and is installed externally to the chiller with both a local display (GPM) and connectivity to the chiller LCD display. The flow rate local display is only on NRC products. This kit is for all refrigerant chillers: EFC2400, NRC1200, NRC2400, NRC5000, VRC1200, VRC2400, and VRC4500.

Water Filter Kit

387004279

Hot swappable, 5-micron water filter for filtering particulates from the coolant circuit.

![](/thermal-wizard/images/accessories/flow-bypass-kit-thumb.png)

Flow Bypass Kit

387010608

This externally installed valve is for reducing the overall flow to the application. Full flow continues through the chiller to maintain high heat transfer rates and temperature stability. This kit does not contain a flow meter.

![](/thermal-wizard/images/accessories/pressure-bypass-kit-thumb.png)

Pressure Bypass Kit

387010420

This pressure bypass kit prevents high pressure operation and can either operate partially open or open when there is a change in operation (e.g., flow to application stopped). It can be used for flow control but operates with less precision. This pressure bypass maintains full flow through the chiller heat exchanger.

### Cord Options

These power cords have been tested and validated on Nextreme devices.

Power cord is not supplied with the unit and must be ordered separately.
