XI'AN, China - Tennsun -- When warranty becomes action, customers win. LIB Industry recently turned its 3-year warranty into tangible uptime for two Southeast Asia customers in August 2025 — and the fixes tell a useful story for anyone using environmental test chambers.

Penang — Hitting 32 °C / 90% RH Without Visible Water

A toy-car maker needed continuous runs at 32 °C / 90% RH inside a temperature and humidity chamber (TH-800A) while specimens stayed packed in cardboard. The catch: no pooling or visible water in the workspace.

What LIB did on site:

Humidification housekeeping: repositioned the water cup feeding the humidity probe and set tank levels to eliminate overflow risk.

Refrigeration balance: retuned PID heat–cool balance to reduce evaporator frosting and stop condensate dripping through front-baffle perforations.

Quick result: stable T/RH at the target point and a dry workspace.

Takeaway: small fluid-path and control tweaks can prevent big production headaches — and are best addressed during co-engineering or at build time.

Singapore — Compressor Swap for a Walk-In Chamber

A TH-0016B walk-in chamber at a Singapore site couldn't reach −40 °C and had persistent compressor noise. Because it was covered by LIB's 3-year warranty, engineers performed a full on-site compressor replacement.

Outcome: low-temperature performance restored and acoustic nuisance removed — with minimal downtime.

Preventive Care — NUS Composite Salt Spray Tune-Up

The same visit included preventive inspection at NUS: water & electrical lines, spray tower and atomizing circuits, plus temp/humidity subsystems — keeping the composite salt spray chamber calibrated for continuous research.
