Nakatani RKE series Compact Water Tank Equipped Inverter Chiller

Manufacturer: Nakatani Co., Ltd.
Model: RKE series
Features
The inverter compressor directly tracks load fluctuations and maintains high precision control while minimizing energy use.
Orion’s unique capacity control also ensures high precision performance, even at low loads where accuracy is usually hard to maintain.
You can switch between energy saving mode and high precision mode at low loads depending on your needs.
This unit reduces energy consumption by 30% at full load compared to energy-saving ON/OFF control chillers.
It also delivers up to 65% energy savings when compared to hot gas bypass or proportional valve PID control chillers that prioritize temperature stability.
You can achieve high precision control of ±0.1°C* and use the unit for various applications that require strict temperature accuracy.
For example, it works well with lasers for precision machining, semiconductor manufacturing equipment, and analytical instruments.
*Applies when the load and ambient temperature remain stable.
You can control liquid temperature in a wide range from 5°C to 35°C, which supports many different applications.
Running at higher temperatures also helps prevent condensation on piping.
You can now use the unit in tougher environments, thanks to its expanded ambient temperature range from -5°C to +43°C (for water-cooled type: +2°C and above).
If the ambient temperature drops below 5°C,
you need to apply anti-freezing measures to the external piping.
You can operate the unit more easily with the angled control panel, which improves both operability and visibility.
The water tank is placed at the top, so you can fill it easily and check or clean the water inside without hassle.
The condenser’s dust filter (air-cooled type) uses a one-touch system that lets you attach and remove it effortlessly.
