Julabo Forcing test heating/cooling thermostat DYNEO DD-1001F-BF
The Julabo DYNEO DD-1001F-BF forcing test heating/cooling thermostat is the preferred choice in breweries and research laboratories for determining the turbidity-free shelf life of beer. Unlike conventional forcing test systems, this model allows artificial ageing to be simulated repeatedly using pre-programmed temperature profiles, allowing brewers and quality analysts to select the ideal test cycle. Similarly equipped laboratory instruments such as the [Julabo CF41] offer comparable precision options, but are nowhere near as consistently geared towards forcing test requirements as this model.
Versatile laboratory solution for precise temperature cycles
This heating and cooling system has been specially developed to cover the entire spectrum of beer quality controls through reproducible temperature cycles. The integration of an external Pt100 sensor and the infinitely variable pressure pump ensure permanently precise temperature values that are equally reliable for large-scale tests or small-volume batches. Similar to the [Julabo CF41], this device also offers high performance for different applications. However, its large volume and convenient handling make it ideal for more extensive beer tests.
Technical highlights
- Working range from -38 to +100 °C for a wide variety of test methods
- Very fine temperature stability of ±0.01 °C
- Bath volume from 48 to 56 liters, ideal for up to 20 bottles of 0.5 liters each
- High-performance pressure pump with a flow rate of 8 to 27 l/min
- Built-in programmer for time sequences with up to 8×60 freely adjustable steps
- USB and optional RS232 interface for data transfer
- Robust stainless steel bath with integrated Plexiglas cover
In addition, the temperature program can be adjusted at any time to vary as required. There is also flexibility in the power supply (230 V/50 Hz as standard), as other voltage variants are available on request
With the integrated PID3 cascade temperature control, oscillations in the temperature curve are avoided as far as possible. The large-format TFT display supports the multilingual user interface and enables intuitive navigation, making this model ideal for laboratories with changing personnel.
Special options and certifications
The forced test thermostat meets the current requirements of DIN 12876-1 and falls into class III (FL). Thanks to this classification, it is suitable for liquids with a maximum viscosity of 50 cSt, meaning that ethanol, water or special heat-conducting oils can be used without any problems. The design with stainless steel bath tank and removable cover also ensures quick cleaning and maximum safety in everyday use.
Concrete fields of application
- Shelf life determination in breweries: To determine beer stability with repeated temperature changes under controlled conditions.
- Research and development: Test cycles for new types of beer or recipes that are to be tested for long-term stability. Often in combination with standard photometer systems for turbidity measurements.
- Food control: In addition to beer, investigations are also possible in which the temperature stresses of food stability or packaging integrity must be tested.
- Quality testing in craft breweries: Smaller production facilities benefit from the ease of use and precise temperature cycles to test their beers for flavor stability and flocculation behavior in a short time.
FAQs
How time-consuming is it to clean the bath?
The stainless steel design is easy to clean. Residues from tempering liquids can be rinsed off easily, and the removable Plexiglas cover allows easy access.
Can I use other bottle sizes?
Yes, the insert supplied is for 0.5 liter bottles. However, inserts for different bottle sizes are available on request so that you can carry out tests with alternative containers.
Is the device compatible with common data acquisition programs?
The USB port and the optional RS232 interface can be used to establish a connection to numerous laboratory information systems or monitoring programs. This allows temperature curves or test results to be seamlessly documented.
Which liquids are particularly suitable for the forced test process?
Ethanol-water mixtures in particular, as well as certain heat transfer oils or glycol solutions, are used at different temperatures. The maximum permissible viscosity is 50 cSt, which covers many standard temperature control fluids.
Are the temperature profiles already stored in the device?
Yes, the device offers an integrated programmer with up to 8×60 steps. You can store both standard profiles and user-defined programs and change them as required.
Can the temperature control also be monitored externally?
A Pt100 connection is available for this purpose, which enables external measurements. This allows you to additionally safeguard and calibrate the process.
Do I need to consider anything about the refrigerant?
The refrigerant contained (R449A) has a global warming potential of 1397. It should be handled in accordance with the applicable environmental regulations in order to reduce emissions.
Summary
This thermostat is an ideal choice for laboratories and breweries that require a reliable and adaptable forcing test system. The stable construction, generous bath volume and powerful pressure pump speed up routine tasks and ensure accurate results. At the same time, the PID3 control ensures high accuracy across the entire temperature range. Thanks to sophisticated extras such as the integrated programmer, convenient interface connection and a user-friendly user interface, routine tests such as determining the shelf life of beer can be carried out effectively. This high-end test system therefore offers a future-proof solution to consistently guarantee quality and stability in the beer industry and other food sectors.
