Dual chillers is a dual-channel cooling devices with two independent refrigeration circuits inside. They have independent compressors and evaporators, and parameters that affect the refrigeration capacity, such as temperature range, cooling capacity, flow rate, etc., can be designed separately according to the cooling requirements. However, components such as the cooling water system, condenser and expansion tank, and user interface can be shared typically . This means that you can control the operating parameters of each channel separately on a touch screen.

Advantages of dual chillers

Support multiple operating conditions

Dual chillers can provide cooling with different temperatures, flows and pressures for two devices or two processes at the same time. Taking LNEYA’s FLTZ series as an example, one model can control the temperature range of one channel from -45℃ to +40℃, and the temperature of the other channel from +10℃ to +80℃. If your process requires both cooling and heating, such a temperature zone design can avoid the trouble of frequent switching of equipment.

Independent control of each flow channel

The two circuits of the dual chiller are connected in parallel and will not interfere with each other. If one channel fails, the other will not be affected, with a certain degree of redundancy. When maintenance is required, the other channel can still operate normally without shutting down the entire cooling system.

Smaller footprint

Compared with two independent single-channel chillers, dual chillers integrate two refrigeration circuits into one housing. Because some parts are shared, there is less wiring and the internal structure is more compact. The footprint of most dual chillers is not much different from that of single-channel chillers, but the height is higher. Take our FLTZ dual chiller as an example. The volume can be 50*90*160cm, which means that the footprint is only 0.45㎡. This compact device is very popular for some laboratories and workshops with tight space.

Lower cost

With the same cooling capacity, the price of buying a dual circuits chiller is lower than that of two single-channel chillers. The price difference depends on factors such as model, configuration and brand. However, it is generally 10%~20% cheaper. If you have a limited budget, dual chiller is a good choice.

Application of dual chiller

MRI/CT

MRI magnets, control cabinets and radio frequency systems require different optimal temperatures. The dual chiller can provide them with cooling at different temperatures and flows. In addition, the imaging room needs to be quiet. If multiple single-channel chillers are used, more noise will be generated. Now only one device is needed to complete all operations in a quiet environment.

Pharmaceuticals

Pharmaceutical companies use multi-stage reaction processes, and each stage requires a different cooling temperature. Using a dual-channel chiller can support two process stages at the same time. In addition, you can customize more channels according to your needs.

Battery testing

In order to ensure the performance and safety of new energy vehicle batteries, samples must be tested before mass production. Among them, extreme temperature testing requires cold and hot sources. The dual chiller has different temperature zones, can customize cooling and heating functions, and can provide independent temperature control for testing.

The above is just a small part of the wide range of applications of this temperature control system. All processes that require different temperatures can use it, such as wafer manufacturing, chip testing, laboratory equipment cooling, laser cutting machine cooling, etc. If you don’t know if it is suitable for your application, we are happy to answer you.
