With the introduction of the new 1201F cooling machine, Julabo is offering environmentally friendly and energy-efficient refrigerated circulators from the Corio and Dyneo series with a large bath volume and a working temperature range of -40 until +100 °C with a powerful cooling capacity of 1.25 kW at 20 °C.

Powerful refrigerated circulators from the Corio and Dyneo product brands have played an indispensable role in laboratories and industrial applications worldwide for years. The new models Corio CD-1201F, Corio CP-1201F, Dyneo DD-1201F and Dyneo DD-1201F-BF work sustainably and future-proof with natural refrigerants. If the 1201F is not cooling under full load, the compressor and ventilator switch to the partial load range, which significantly reduces the sound level. For internal temperature control applications, the optimized design of the refrigerated circulators offers an above-average bath opening and more space in the bath tank. This means that not only larger samples, but also more samples can be tempered at the same time.

The new refrigeration units offer impressive energy-saving potential up to 70 percent: Electronic expansion valves, speed-controlled compressors and ventilators allow for usage-dependent power consumption. This leads to significant operating cost savings in many application scenarios and therefore to a faster amortization of the acquisition costs.

Energy efficiency
Energy efficiency is a measure of energy expenditure or energy consumption. A temperature control system is energy-efficient if it achieves a specified target with the lowest possible energy consumption.

To estimate the potential savings, the specific planned purpose of the systems must be considered. For many typical applications in the laboratory or industry, a fixed setpoint value is specified at the beginning of the temperature control process, and the temperature control instrument then attempts to reach this value in the shortest possible time. To do so, every component involved is operated under high load. Once the set point is reached, the desired temperature is usually just maintained. During this phase, it is sufficient for the components involved, e.g., fans or compressors, to operate at partial load. In these use cases, energy savings of up to 75% are possible when using energy-efficient temperature control systems.

In the past, Julabo has often used electronic expansion valves for refrigerated circulators with a cooling capacity of 600 W or more in order to realize energy savings, among other things. The latest generation of refrigerated circulators is also equipped with speed-controlled compressors and fans to provide greater savings potential.

Conventional refrigerated circulators with a cooling capacity of less than 500 W are generally designed as capillary tube systems. These systems require comparatively little energy due to their low absolute cooling capacity. Using more expensive components, like electronic expansion valves and speed-controlled fans or compressors, to realize energy-saving potential would significantly raise the price of these systems. At the same time, the overall effect in terms of energy savings would be very manageable due to their low cooling capacity.

With refrigerated circulators of 800 W or more, the energy savings result in rapid amortization of the initial additional costs. If the application involves different temperature ramps and load requirements and the partial load range is leveled out at approx. 50%, the resulting energy savings amounts to 400 watts per hour.

With low electricity costs, these systems have an amortization time of less than 2 years in many use cases. At the same time, their lower energy consumption helps to protect the environment.
