Features

Widened Ambient Temperature Range for Use

You can operate the unit under harsh conditions, even in summer temperatures up to 50°C (with an optional accessory)1. It performs reliably in factories where hot air tends to accumulate. You can also install it outdoors in cold regions, as it handles winter temperatures down to -20°C2 with peace of mind.

*1 Excludes RKE11000B1-V(W)
*2 Applies to air-cooled units only. Anti-freeze mode setting is required.

Expanded Operating Temperature Range (Liquid Temperature)

The unit supports a wider liquid temperature range, from 3°C to 35°C.

Inverter-Driven Pump

The pump now also uses an inverter, in addition to the refrigerator and fan. It delivers only the required flow rate, so you don’t need to adjust the bypass valve and avoid unnecessary flow.
You can select the pump control method—set by operating frequency, flow rate, or water supply pressure—based on the guideline flow rate standard. This allows you to run it at the optimal flow or pressure according to your load.

Intelligent Touch Panel

You can easily operate and check various settings and conditions by touching the screen.
You can also switch the display language to English or Chinese.

Features include:

• Graph display

• Operation ratio (power indicator)

• Measured pressure

• Menu

• Timer setting

• Easy maintenance and alarm display

• Language display switching

Low-Noise, Quiet Design

The inverter controls the fan to the ideal rotation speed using refrigeration cycle optimization. This significantly reduces operating noise. (Noise is measured 1m in front and 1m high.)

PC and Sequencer Operation

The control program lets you use the communication function based on your needs.

Communication Methods:

• USB: 1 unit

• RS-422A: 32 units

• RS-485: 32 units

What You Can Operate via PC:

• Turn the chiller on/off individually

• Turn the chiller water pump on/off individually

• Set the chiller liquid temperature individually
