Process chillers, sometimes referred to as circulating chillers, or recirculating water chillers, are primarily aimed at heat-removal from a heat-generating process. Their location varies from indoor usage to outdoor usage so they must be able to deal with varying weather conditions such as ambient temperatures extremes, to rainfall and snowfall.
Cooling requirements can range from a few Kilowatts of heat removal to several hundred Kilowatts, depending upon the application. If the unit is placed in a remote location, then it will be necessary to have some way of communicating remotely with the process chiller for the purposes of remote start/stop, parameter changes or fault diagnosis, as it may not always be practical to gain access to the chiller location quickly.
The LAUDA range of chillers lend themselves very well to the variety of applications and environments, whilst providing a robust and power-efficient solution.
Suitable for heat removal across the following application types:

High energy saving and a short payback time
Depending on the operating conditions, the new circulation chillers are significantly more energy-efficient than conventional circulation chillers which are not Ecodesign-compliant.
A modern chiller that conforms with the EU Directive has clear advantages over older devices or products still in use and available outside the EU, which are not subject to the Directive. Some chillers exceed the required SEPR values for energy efficiency by some distance, such as the new generation of LAUDA Ultracool circulation chillers, which meet ecodesign requirements and incorporate a speed-controlled compressor, ventilator fan and electronic expansion valve.
Compliant with the Ecodesign Directive
The new LAUDA Ultracool circulation chillers comply with the Ecodesign Directive 2009/125/EC. This defines the limit values for energy efficiency that process circulation chillers must fulfill.
Short amortization times
The higher purchase price of an energy-efficient chiller, compared to a conventional device, typically amortizes between 1.5 and 2.5 years, thanks to savings made from reduced energy requirements.
The customer can determine the amortization time of a modern, energy-saving circulation chiller compared to conventional devices already in operation based on calculated energy savings, lower water/glycol costs, a tank content reduced by up to 80 percent and the lower maintenance costs of the new device.

Optimized for Industry 4.0
The new process circulation chillers are equipped with an LCD remote control as standard. An Ethernet interface for connection to a computer or local network (LAN) is also integrated as standard. In addition, the Ultracool devices can be controlled by means of a web server via a PC or even mobile devices - an internet connection is not necessary. All you need to do is to configure an IP address for the circulation chiller, which must be in the same network as the terminal device. The LAUDA Cloud enables monitoring and analysis of the device from any computer with an Internet connection – irrespective of location.
