Taipei MRT Zhongshan Station — Fan Bearing (Velcro-Type)

01 The Problem

Taipei MRT's Zhongshan station has hundreds of tunnel fans running 24/7 to keep the platform air moving and to evacuate smoke in case of fire. The fans are nondescript and rarely inspected. When a fan bearing overheats and the fan stops, on a hot summer afternoon the platform can become unsafe within an hour.

The Risk

MRT tunnel fans run 24/7; bearing overheating triggers shutdowns and degrades air quality.

Detection Gap

Fans often need temporary thermal monitoring, where permanent installation is unnecessary.

02 The OctosX Solution

A Thermalpas velcro-strap thermometer wraps around each fan motor housing — no drilling, no internal wiring. OctosX monitors the fan stack temperatures and pages the maintenance team if any fan trends abnormal, before any rider feels the difference.

Sensor & Edge

Thermalpas Velcro-mount type (reusable) + portable IR cross-check.

Cloud Logic & Alerting

OctosX offers a "Equipment Loan" subscription model with monthly billing.

03 The Outcome

TRTC's predictive maintenance schedule now drives off OctosX data. Fans get inspected when they need it, not on an arbitrary calendar. Platform air quality has stayed within spec, and unscheduled fan failures have dropped considerably.

Field Detection

TRTC used "temporary thermal service" to assess each station; 4 stations with bearing degradation found within 3 months.

Quantified Impact

Scheduled repairs followed; OctosX gained entry to TRTC's rail maintenance ecosystem.
