Akribis Precision Direct Drive Motors Singapore cleanroom

Post By Alex, HVAC Engineer Date: June 09, 2026

Akribis Systems manufactures precision direct-drive motors. When they upgraded their Singapore cleanroom, they hit two massive roadblocks: Singapore’s brutal year-round humidity, and a mechanical room too small for standard equipment.

You cannot just shrink an Air Handling Unit (AHU). If you cut the physical dimensions, you cut the cooling capacity and the static pressure.

Here is exactly how we solved it.

1. Custom Modular Footprint Standard commercial units would not fit. We engineered a customized Direct Expansion (DX) system using 6 Purification AHUs and 12 outdoor condensing units. We reorganized the internal functional sections to slash the equipment footprint. It fit the cramped retrofit space perfectly, with zero drop in cooling performance.

2. Frameless Cleanroom Casings Cleanrooms fail when AHU casings leak air or trap dirt in the seams. We threw out standard aluminum frames. We deployed our 50W-Series AHUs featuring a frameless, perfectly smooth interior. No dead corners for dust or bacteria. It strictly passes European EN1886 and German VDI 6022-1 hygiene standards.

3. PLC-Driven Dehumidification Precision electronics die in fluctuating humidity. To beat the equatorial latent heat, we used staged heat exchange paired with a centralized PLC control system. The algorithms dynamically scale compressor output to the actual room load. The result is flatlined temperature and humidity, running 24/7.

4. Boots on the Ground Shipping metal boxes is not engineering. We dispatched our own commissioning engineers directly to the Singapore site. We oversaw the physical installation, linked the systems, and tuned the PLC parameters until the cleanroom passed every single operational requirement.
