Precision Air for Electronics Cleanrooms – HOLTOP Delivers ±1°C Control in a Tropical Climate

2026-05-08

Challenge
A Singapore electronics cleanroom faced three tough conditions:

Tropical heat & humidity (26–32°C, 70–90% RH)
Strict cleanroom requirements (±1°C, ±10% RH stability)
Very limited space for HVAC equipment

Standard systems struggled with humidity load, control lag, and space constraints.

Solution – Custom HOLTOP Direct Expansion (DX) AHU

U-shaped triple-surface heat exchanger + smart controls → achieves ±1°C and stable RH
Compact, non-standard design – fits tight spaces, no cooling tower or water pump needed
Reliable 24/7 operation with low maintenance, suitable for continuous production lines

Full-process support including site survey, factory inspection, fast commissioning, and free replacement of transit-damaged parts.

Result
Stable cleanroom environment, high product yield, and reduced project & operating costs. A proven reference case for HOLTOP’s constant temperature & humidity DX equipment in high-end overseas projects.
