New Standards in Sustainable Refrigerated Circulators in All Performance Classes

What does JULABO classify for the GreenLab Award?
As a future-oriented manufacturer, JULABO prioritizes eco-friendly production and climate-friendly operation in all new developments. The new refrigerated circulators ensure sustainability, precision, and efficiency with natural refrigerants and energy-saving technologies, reducing costs and conserving resources in worldwide labs and research facilities.

Powerful refrigerated circulators under the product brands CORIO, DYNEO, and MAGIO have been indispensable in laboratories and for industrial applications worldwide for years. The latest models come with groundbreaking innovations:

All devices operate with natural refrigerants, making a significant contribution to climate protection.
The larger cooling units, starting at 800 watts of cooling capacity, offer impressive energy savings of up to 70%: Electronic expansion valves, speed-controlled compressors and fans allow usage-dependent power consumption. This results in significant operational cost savings in many application scenarios, leading to a faster amortization of acquisition costs.

New products
The MAGIO MX-1800F and MAGIO MX-2500F are the new flagships of the refrigerated circulators. They boast a strong cooling capacity of 1.87 and 2.57 kW at 20 °C with a working temperature range of -50 ... +200 °C.
With the 1200FW, JULABO now also offers a water-cooled version of this powerful cooling machine for our CORIO, DYNEO, and MAGIO product brands. 

The new models of the proven refrigerated circulators DYNEO DD-200F, CORIO CP-200F and CORIO CD-200F are now also available with natural refrigerants. The entry-level class of refrigerated circulators offers a cooling capacity of 0.2 kW at 20 °C in a very compact design. 
For a selected campaign period, we are making sustainability visible for the laboratory: on request and at no extra charge, you can order selected models of our new energy-efficient refrigerated circulators as a special green edition until 30 June 2025.

What does energy efficiency mean when using temperature control systems?
Energy efficiency is defined as achieving specific goals with minimal energy use. In temperature control systems, energy consumption consists of a base load—required for basic system operation—and usage-dependent consumption, which is influenced by factors like cooling capacity, ambient conditions, and connected devices. Reducing usage-dependent consumption is key to increasing energy efficiency.

Energy-efficient temperature control systems can significantly lower energy use, especially during periods when only partial load operation is required. For many laboratory and industrial applications, the system works hard to reach a setpoint temperature quickly, but once achieved, only partial load operation is needed to maintain it. Under these conditions, energy savings of up to 70% are possible with advanced systems.

Conventional refrigerated circulators with cooling capacities below 500 watts generally use capillary tube systems, which consume less energy due to their low cooling capacity. Incorporating advanced energy-saving technologies, like electronic expansion valves and speed-controlled components, in these low-capacity systems would be cost-prohibitive and yield minimal energy savings. However, for higher-capacity systems (600 watts or more), these advanced features provide significant energy savings.

JULABO, a manufacturer of temperature control equipment, has incorporated electronic expansion valves into its refrigerated circulators with 600 watts or more capacity for improved energy efficiency. Their latest generation, including models like the MAGIO MS-1200F, features additional energy-saving technologies such as speed-controlled compressors and fans. These advancements make the MAGIO MS-1200F the first in its power range to offer these energy-saving capabilities.

Comparing the MAGIO MS-1200F to the MAGIO MS-1000F reveals substantial energy savings. In scenarios where the system operates at a lower partial load, the MAGIO MS-1200F consumes approximately 600 watts less energy. Even when operating at full capacity while cooling from +20°C to -20°C, it requires 150 watts less energy. The energy savings increase as cooling capacity demand decreases. In practical applications where systems rarely operate at full capacity continuously, typical energy savings range from 40% to 60%.

The article also discusses amortization, highlighting that for refrigerated circulators with capacities of 800 watts or more, energy savings quickly offset the higher initial costs. Based on a typical scenario where the partial load is around 50%, the MAGIO MS-1200F saves approximately 400 watts per hour compared to the MAGIO MS-1000F. With global variations in electricity prices, example calculations demonstrate that these energy-efficient systems often pay for themselves within two years. This rapid payback period is especially achievable in applications with higher usage and electricity costs.

In conclusion, energy-efficient refrigerated circulators, particularly those with cooling capacities above 800 watts, offer significant long-term cost savings and environmental benefits. Despite their higher purchase price, the energy cost reductions typically result in amortization within two years while also contributing to climate protection through reduced energy consumption.
