Customer : A well-known petrochemical testing laboratory in South America
Product : Lubricating Grease Salt Spray Test Chamber
Challenge : Multiple technical requirements did not align with our standard product specifications
I. Customer Requirements & Challenge
In early 2025, we received an inquiry from a South American customer seeking a salt spray test chamber compliant with SH/T 0081 for evaluating the corrosion resistance of their grease products.
However, the customer raised three special requirements in their technical questionnaire:
Power supply : Must be 110V / 60Hz (our standard is 220V / 50Hz)
Spray mode : Requires one key switching between intermittent and continuous spray, plus a remote control interface
Temperature control : Temperature stability must be ≤ ±0.3℃ (our standard is ±0.5℃)
None of our standard models could fully meet these three points.
II. Our Response Strategy
We did not simply reply “we cannot provide.” Instead, we took the following actions:
1. Technical Evaluation & Custom Solution
Our R&D team analyzed each requirement point by point
Confirmed that without changing the overall structure, we could achieve 110V / 60Hz by replacing the power module and upgrading the control system
Developed a temperature control optimization plan using higher precision sensors and an improved PID algorithm, achieving stability of ±0.28℃ – exceeding the customer’s expectation
2. Spray System Upgrade
Added a control program module to the original tower spray system, enabling menu based switching between continuous and intermittent spray
Integrated an RS485 remote communication interface to support connection with the customer’s existing LIMS system
3. Transparent Communication & Prototype Testing
We proactively proposed to modify and test a prototype first, then sent the test video and data report to the customer
Test results showed stable salt spray deposition at 1.5 ml/80cm²·h with no abnormality after 72 hours of continuous operation
III. Results & Customer Feedback
Contract signed : The customer signed the official contract within two weeks after receiving the test report
Delivery & acceptance : The equipment was produced and shipped 45 days after the contract was signed. It passed the customer’s on site acceptance test on the first attempt
Customer comment (translated from original Spanish) :
“Dalian Analytical Instrument Factory not only solved our technical problems but also demonstrated true professionalism and cooperation. They were willing to customize equipment for a customer in South America – which is very rare in our procurement experience.”
