18 Energy-efficient refrigerated circulators Decrease operating costs while protecting the environment


Refrigerated circulators ensure reliable, accurate temperature control for applications involving samples, test specimens, and processes in, e.g., basic research, material testing, or technical systems. In many of these applications, partial load operation is usually sufficient for efficient heat withdrawal. Energy-efficient refrigerated circulators can help users save on operating costs while also reducing their environmental impact.


What does energy efficiency mean?


Energy efficiency is a measure of energy expenditure or energy consumption. The objective of being energy-efficient is to use as little energy as possible. A temperature control system is energy-efficient if it achieves a specified target with the lowest possible energy consumption. For example, with precise temperature control of an application. The less energy needed to reach the specified target, the more energy-efficient the temperature control instrument is. Products on the market with a similar function and performance can be used as a reference.


Potential energy savings in temperature control systems


When investing in new temperature control equipment, it is important to carefully verify the expected operating conditions for the desired systems so that the corresponding potential energy savings can be taken into account.


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 70% 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 realise 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. With the 800F and 1200F cooling machines, the new refrigerated circulators are thus the first systems in their power range on the market that make use of this energy-saving 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 realise 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


Amortization time


With refrigerated circulators of 800 W or more, the energy savings result in rapid amortization of the initial additional costs. The costs are reduced as a result of the energy savings and electricity price. 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.

61565pr@reply-direct.com The new energy-efficient refrigerated circulators 800F and 1200F


Julabo refrigerated circulators from the CORIO, DYNEO, and MAGIO series are known for their premium quality, flexibility, and performance as well as their impressive efficiency. The newly developed 800F and 1200F cooling machines work with natural, environmentally-friendly refrigerant and were designed with a focus on energy efficiency. This means significant savings with respect to the operating costs for numerous applications, which also means faster amortization of the procurement cost. At the same time, their lower energy consumption helps to protect the environment.


The CORIO CD-800F, CP-800F, CD-1200F, and CP-1200F refrigerated circulator offer an outstanding price/performance ratio. They are ideal for all standard tasks and routine work in laboratories and industry.


The refrigerated circulators from the CORIO CP series are particularly well-suited for applications in the temperature range up to +200°C. Thanks to their stronger pump capacity, they are ideal for simple temperature control applications with external systems.


The DYNEO DD-800F and DD-1200F refrigerated circulators have a broad working temperature range as well as an impressive cooling capacity, despite their compact design. They are particularly suitable for temperature control applications with internal and external systems.


As with all circulators from the MAGIO series, the MS-800F und MS-1200F refrigerated circulators stand out thanks to their premium quality, high performance, and intuitive operation using the TFT touch display. These systems feature extra powerful pressure and suction pumps in order to satisfy the high requirements of external temperature control applications. More information online: ilmt.co/PL/o7XJ

TE400 Peltier cooler With their robust design and precise temperature control, Peltier coolers are ideal for simple temperature control tasks in laboratories and research facilities. They work without refrigerants and are therefore very environmentally friendly. At the same time, the reliable chillers help reduce operating costs and reduce the ecological footprint thanks to their energy-efficient operation.


The TE400 uses less moving components such as compressors for cooling. This means it requires comparatively little maintenance and is less susceptible to wear. It offers a cooling output of up to 400 watts and a pump output of up to 7 l/min and impresses with its high temperature stability for a variety of different applications.


Silent mode


The TE400 Peltier cooler is equipped with an additional operating mode for use with lower cooling performance requirements. The noise level is significantly reduced in silent mode and thus contributes to a more pleasant working atmosphere. More information online: ilmt.co/PL/M5nX
