Advansor has recently released a wide range of dedicated controller platforms to control CO2 systems and to suit the clients’ requests. In cooperation with the companies Danfoss, Carel, Wurm and RDM, Advansor has now integrated a range of these new controllers into their product offerings.
One of the reasons for offering multiple controllers to the market is request from the service companies to continue handling controllers, which they are already familiar with. This allows the commissioning teams to work safer and more efficiently.
Another reason for offering multiple controllers is to ensure compliance for the end user’s choice of cabinet control and to provide trouble free integration to the store front end systems. The simpler and more reliable approach to avoid errors is to ensure uniformity on the controller brands.
Key features of new controller platforms
There is also a growing request for a visual presentation of the user interface by using for example touch screen enabling plant maps, trends and logs to be displayed directly. This allows the service of the system without the use of a PC. Improved functionality for heat recovery applications has also been a key factor in the development of this new generation of controllers.
All new controllers can be offered over the full range of Advansors’ product range for supermarket systems. The individual controllers and their summarised technical features are listed below:
The product builds on the popular AKPC-740/780 functionality with improved features based on important experience from the field.
Carel pRACK CO2
The development of the control system with WURM has been targeted to the German and Swiss markets where the need for heat is in excess of the recovered store heat. In such case a borehole or the ambient are included to the add compressor load.
The Danish supplier manufactures and sells CO2 thermal systems for heating, cooling and refrigeration in combined heating and power plants, food factories and the process industry. It is one of Europe’s leading producers of transcritical CO2 refrigeration systems and also offering analysis and consultancy to ensure optimal energy and cost savings. End of 2011 Advansor was acquired by Hill PHOENIX Inc. generating a combined figure of 600 CO2 systems in supermarkets in the US, Canada and Europe.
