The Necessity of Regular Water Replacement in Formaldehyde Test Chambers

Source:LINPIN Time:2025-03-19 Category:Industry News

The daily maintenance and care of a formaldehyde test chamber are crucial and should be given due attention. For example, the water in the chamber’s water tank needs to be changed regularly, which is absolutely necessary. These details should be noted during the routine care of the equipment.
Why is it necessary to change the water regularly in a formaldehyde test chamber? If the water in the tank is not replaced for a long time, it can lead to contamination, rusting, and corrosion of the water tank. In more severe cases, it may even cause the tank to leak and damage the machine. With the changing seasons, the water in the tank also requires different treatments and maintenance. For instance, during winter when the temperature is low, the water in the tank should be drained when the formaldehyde test chamber is not in use to prevent the water from freezing and expanding, which could damage the equipment. The water in the test chamber’s tank generally needs to be changed every two months. However, if the chamber is used in an environment with high levels of dust or formaldehyde VOC concentration, the water should be changed monthly. The water used in the equipment is usually filtered or softened pure water or distilled water.
