As the after-sales service team of Zhengzhou Changcheng Technology Industry and Trade, we occasionally receive inquiries from customers about "the cooling speed of the temperature control equipment in the laboratory has slowed down"... After investigation, we found that many times it is not the equipment itself that is malfunctioning, but the accumulation of dust in the condenser that is gradually affecting the operation of the equipment.

Especially the precision temperature control equipment used in laboratories and factories has high requirements for temperature. As the core component of heat dissipation, if the condenser is blocked by dust, it will slow down the cooling rate and fail to reach the required temperature. In severe cases, it may also trigger overheating protection and even shorten the service life of the compressor. This has a significant impact on experiments or production that require continuous operation.

Why do finned condensers need to be cleaned?

The fin condenser has a very small spacing between fins to increase the heat dissipation area, but this also means that even a small amount of dust and fibers may clog the gaps. For example, common dust in laboratory environments and oil particles in factory workshops can easily adhere to fins, forming a "thermal insulation layer". According to our company's after-sales data, equipment that is regularly cleaned has a lower failure rate than equipment that is not cleaned for a long time60%As a device manufacturer, we have a better understanding of how to protect core components during cleaning. Following this step is both safe and worry free.

Zhengzhou Great Wall Technology Industry and Trade recommends a three-step cleaning method:

STEP1Shutdown and power off, confirm the "clean area" and turn off the equipment power first, wait 30 Allow the compressor to cool down in minutes. The condenser of circulating coolers and low-temperature coolant circulating pumps is often located on the side or front of the equipment (with protective mesh covers); (Please refer to the equipment manual or contact after-sales service for details).

STEP 2Using specialized tools, the key is to use a "light brush in the forward direction". When our after-sales engineers come to our site, they often use soft wool brushes, and everyone can also use similar tools.⚠Key point: It must be gently swept along the direction of the fin arrangement, and must not be rubbed horizontally or poked with hard objects. Excessive force may cause deformation and affect the heat dissipation effect. If encountering stubborn stains (such as a small amount of reagent residue), you can gently wipe them with a cotton swab dipped in pure water, then air dry before turning on the machine (do not use organic solvents such as alcohol to avoid corroding the fin coating).

STEP3Deep cleaning, can be combined with cold air blowing: after brushing off floating dust, use a hair dryer to blow cold air into the gaps of the fins (distance from the equipment)30cmAbove), it can take away deep dust. If it is a dusty environment such as a workshop, it is recommended to clean it every month1Secondly; The laboratory environment can be2-3Monthly cleaning1Next time.

After sales tips:

If the following situations occur, please feel free to contact us: If there are still problems such as poor cooling effect and frequent alarms after cleaning, you can contact our after-sales team at any time, and our after-sales engineers will provide you with corresponding services; As a deep practitioner in the field of scientific research 37 As a manufacturer of temperature control equipment, we not only focus on the performance of the equipment when it leaves the factory, but also attach great importance to its long-term stable operation in actual use. Regular cleaning may seem simple, but it is a practical way to protect equipment. You focus on laboratory and production, as well as equipment maintenance matters. It would be more reassuring for us to handle them.
