Have you ever encountered a situation where the cooling equipment suddenly failed while you were doing an experiment? If you can’t restart it, those temperature-sensitive experiments will face failure. Maybe you should consider a more stable redundant cooling system.

What is a redundant cooling system？

---

In addition to the main cooling system, the redundant cooling system also has a backup system. The main system and the backup system are connected in parallel, so they will not interfere with each other. Redundant chillers are often integrated with PLC or BMS automatic control systems to monitor operating status.
 
When the main system is abnormal, it will immediately switch to the backup system to take on the cooling work. Common redundant cooling systems include dual chillers, modular chillers, and backup refrigeration compressors.

Why use redundant cooling systems？

Continuous operation

---

Some chemical reaction experiments and material testing experiments have strict temperature requirements. After the temperature control system stops, the experiment cannot be carried out under suitable temperature conditions. Some samples are difficult to obtain, such as cells or reaction intermediates, which may be scrapped at room temperature.
 
All the time and cost invested during the experiment are wasted. Some material testing experiments with longer experimental cycles can only be started from scratch after interruption. This is a blow to researchers. If a redundant system is used, the backup cooling circuit can take over the cooling task in time to ensure that the experimental process is not interrupted.

Protecting equipment

---

The vacuum pumps, electron microscopes, reactors, etc. in the laboratory are relatively expensive. If the cooling system fails, these equipment are easily damaged at high temperatures. Whether it is repair or repurchase, it costs money. The redundant cooling system can use backup cooling to protect expensive experimental equipment when the main system fails.

Safety hazards

---

Many experiments are accompanied by exothermic reactions. The accumulation of heat in closed equipment will increase the pressure and bring safety hazards. If the chiller stops during the experiment and the reaction temperature cannot be controlled, it may cause the reaction to get out of control, leading to explosions, hazardous material leaks, or fires. The redundant system can immediately start the backup unit and respond at the fastest speed to eliminate potential risks.

Laboratory standards

---

The construction and use of laboratories need to meet safety and quality standards. For example, ISO/IEC 17025 requires that laboratories must have backup systems to prevent equipment failures from affecting experiments. GLP (Good Laboratory Practice) emphasizes the need for emergency measures to deal with equipment failures and shutdowns.
