CT Scanner Cooling System Faults

By MedBazaar Technical Team · Troubleshooting Guide

مسئلہ / Problem

CT scanner cooling warnings, tube overtemp, ya chiller faults.

Cooling Components

**X-ray tube oil cooling** — tube ke andar oil circulates

**Gantry cooling fans** — electronics cool karte hain

**External chiller** — large scanners mein water-based cooling

**Room AC** — ambient temperature control

تشخیص / Diagnosis Steps

Which cooling component ka error hai identify karein

Room temperature check karein

Abnormal sounds: grinding fan, water leak sounds

Chiller unit (agar hai) status check karein

حل / Fix (User Level)

Room AC check karein — minimum 18°C room temperature maintain karein

Fan filter grills clean karein (external accessible grills only)

Scan load reduce karein — heat buildup kam hogi

Engineer Actions Required

Chiller coolant level check aur refill

Coolant leak repair

Fan replacement

Oil cooler inspection

Thermal paste replacement

Pakistan Climate Note

Pakistan ke garm mausum (April-September) mein CT cooling issues increase ho jate hain. Room AC backup/redundancy highly recommended hai. AC failure = CT downtime = revenue loss.

Difficulty: Advanced — Engineer Required
