After Sales Service
36 months warranty and lifelong follow-up services. Both our after-sales team and local service centers are available to serve you quickly and efficiently. Our 24-hour assistance request system allows us to understand your questions in a very timely manner.

How to Service

If users face operation problems, our after-sales team will guide the operation in time through online assistance and provide videos and files.
If the test chamber fails, we have two solutions. First, we will arrange the local service center to solve the problem on site. Second, our after-sales team will check the problem and troubleshoot it. If there are damaged parts, we will arrange express delivery immediately, and then instruct the customer to install the new parts. This is very efficient.
If the customer needs on-site service, we will send engineers to the customer’s site to solve the fault and provide training.
If there is a major failure of the test chamber and the customer cannot use the equipment after receiving it, we will produce a new test chamber (same as the old one) for our customer free of charge.

Equipment Maintenance

Effective equipment maintenance can greatly improve the service life of the equipment, reduce the failure rate, and reduce energy consumption.
Maintenance procedures vary depending on equipment type. Please obtain the system maintenance manual from LIB Industry according to your equipment model.
 
 
 
 
 
 
 
 
 
Lib Installation Service Process
LIB provides standardized installation services for all environmental test chambers—from small temperature & humidity chambers to large walk-in chambers. The following steps show what customers can expect during on-site installation.
Service-1

On-site Check & Environment Assessment

After the equipment arrives, our engineers start with a basic but very important inspection.
0+

For All Equipment

 Verify the power supply, voltage and grounding.
Check the water connection (for humidification or spray functions).
Confirm the installation area is dry, clean and safe.
Confirm door direction and operator space with customer.

Additional Checks for Detachable Walk-In Chambers

To ensure safe and smooth installation, we will:
Check the access path, such as doorways, corridors, turning space, elevator size, etc.
Check floor load-bearing capacity and levelness.
Plan the lifting or module-moving route.
Check the installation area’s power, water, drainage and ventilation conditions.
Ensure enough space for installation, operation, and later maintenance.
