CUMULUS® Fluid Temperature Control – A fast solution for process cooling

The fastest answer to your fluid temperature control needs In many production processes, the low temperature cooling of process fluids is often both necessary and beneficial. This is to achieve a high degree of process control and stability as well as to increase product quality, yield and selectivity.

The CUMULUS® Fluid Temperature Control (FTC) system is the optimal solution for rapidly bringing your process down to temperatures between –30 and –120 °C, with unchallenged accuracy. The system uses liquid nitrogen as cooling medium to automatically cool process fluids in a highly controlled manner.

CUMULUS® FTC system solutions are utilized across Europe and throughout the Americas, efficiently solving cooling demands for a wide variety of customers. Common fluids cooled by the system for customers within the pharmaceutical and chemical-process industries are: methanol, toluene, SYLTHERM® XLT, brine, and many others.

The cryogenic cooling systems combine all Fast and flexible The CUMULUS® FTC system is insensitive to load variations or changes in inlet temperature and flow of the process fluid, owing to its outstanding process dynamics. The system is able to maintain its fast response and impressive cooling capabilities with an accuracy of ±1 °C, at any cooling duty within the system’s operating range. By this you secure that your production cooling temperature is always kept constant.

Compact design The CUMULUS® FTC system can be fitted into your process line without modifications or production disturbances. There is no need for a specially designed building or room to house the system. You can even easily move the system around in your facilities to serve different cooling needs. With its patented efficient heat exchanger package, it offers lower weight and height as well as a smaller footprint when compared with other cooling solutions.

Unique on-site test service We at Linde provide a unique test service that offers you the advantage of conducting full-scale operational trials with a CUMULUS® FTC system in your process on site. This completely ensures you that the system is the optimal solution. The system will be delivered directly from our equipment pool.

Environment-friendly design This system constitute an unbeatable environment-friendly alternative. Since it emits no CFC, you do not need to worry about new regulations on ozonedepleting substances. Furthermore, the nitrogen that is used as cooling medium is a natural and pollutant-free refrigerant, which is either released back to atmosphere or reused in your process for any number of purposes.

the attractive benefits you are looking for Easy to install To minimize your production down-time, the CUMULUS® FTC system can be quickly integrated into your production or existing cooling system. It can be installed either indoors or out without the need of rebuilding your facilities. The installation work is minimal: the system needs no special foundation and can be installed in a few days. Linde’s skilled and experienced service personnel will assist you during the initial startup period by carrying out site acceptance testing and safety checks. You can thus have your system up and running within a few months from the order date.

Easy to operate The fully automatic system is very easy to operate and needs no special operating personnel or supervision. After a minimum of preparation, the normal startup and shutdown procedures are simple and brief. Once the liquid nitrogen has been fed to the unit, the CUMULUS® FTC system becomes operative within a few minutes after simply pressing the start button. To further increase simplicity and speed up your startup procedures, Linde assists you by initiating tuning procedures as well as by providing basic training.

CUMULUS® FTC modular systems CUMULUS® FTC units of different sizes have been developed to build up a flexible modular product family, with different cooling duties and cooling temperature ranges to cover a variety of cooling needs. The modules can be used for either batch or continuous cooling. Their wide operating ranges allow for greater flexibility in quickly and reliably adapting to changing plant conditions. All modules are standardized and delivered as complete systems that require very little extra work. This enables you to get your CUMULUS® FTC system up and running quickly and smoothly. After thorough testing, each unit is delivered to your site along with complete documentation.

Smart, patented technology The CUMULUS® FTC systems are based on a patented technology from Linde. This solution minimizes any problems or risk of freezing as regards the process fluid. Direct heat exchange between the cold liquid nitrogen and the cooling fluid is avoided. Instead, cold vaporized nitrogen gas is utilized as the intermediate heat-exchange medium, resulting in fast and efficient cooling.

Reliable The units have a rugged design without moving or rotating parts, which ensures long operating life and increased reliability. This benefits you through its low maintenance and service needs, thereby reducing operating costs and production stops. Furthermore, your total operating costs are lowered to an absolute minimum if the nitrogen gas is reused for other purposes, for example inerting, in your production facilities.

Automatic operation The control system provides you with the option of easily operating the unit automatically, either locally or remotely. The CUMULUS® FTC system can be delivered with or without a control system, whatever suits your situation best.

CUMULUS® PX20

For small-scale pilot-plant operation or laboratory purposes, this unit represents a small and easily handled system with a cooling capacity up to 5 kW. This unit can also be used as a central cooling unit in other equipment. It is, for example, used as a cooling module in freezedryers. Cooling temperatures of –100 °C can be reached.

This unit can be used for cooling needs in pilot-scale to small-scale production. The CUMULUS® PX20 cools down to –100 °C, with a cooling capacity up to 20 kW.

From lab scale...

Flexibility to meet your different needs Different sizes The availability of five different modules allows you to choose the optimal system for your particular cooling needs. The main parameters in choosing a model are the required cooling capacity, flow and temperature.

Easily expandable Any CUMULUS® FTC module can be readily expanded merely by connecting a new module parallel to the existing one. Each module can be further tailored to your requirements by utilizing a wide range of optional accessories such as heating units and valves and sensors for a number of functions.
