Cleanroom Air Control for a Tier-3 Hospital

IndustryHospital Cleanroom
LocationChengdu, China
ScaleTier-3 / 8 OT rooms
Year2025

Project Background

A new surgical suite required stable temperature and positive pressure to meet infection-control standards.

Our Solution

DANRENS PID controllers managed supply-air temperature and frequency drives on AHUs, with continuous differential-pressure monitoring at the anteroom.

Results

The suite passed validation on the first attempt, holding 22±0.5°C and the required pressure cascade around the clock.
