Cleanroom HVAC systems for contamination control.
The envelope defines the room. The air system is what actually makes it a cleanroom, and holds it there through every shift, every season and every audit.
We understand the art and science of handling air.
Temperature, humidity and particle count are not three separate problems. They are one system behaving as a whole. A dehumidifier sized without reference to the fresh-air load, or a pressure cascade designed without reference to door openings, will pass on the day of qualification and drift within a month.
We size, install and commission the complete low-side and high-side scope, so the ACPH, the cascade and the setpoints in the design basis are the ones actually achieved on site.
- Heat-load and fresh-air calculations tied to your real occupancy and process
- Filtration staged pre → fine → HEPA H13 / H14 at ≥99.97% @ 0.3 µm
- Pressure cascade engineered in 10–15 Pa steps between classified zones
- VFD and control strategy that holds setpoints at partial load
The AHU range we manufacture
Double-skin and single-skin units built in our own plant and configured to the plant room you actually have, not the one the catalogue assumes.
Double-skin AHUs
Thermally broken double-skin construction for critical and classified applications.
Single-skin AHUs
Cost-effective units for comfort and non-classified process air.
Floor-mounted AHUs
Standard plant-room configuration with full service access.
Ceiling-suspended AHUs
Where plant-room floor area is unavailable or better used.
Re-circulation AHUs
High-ACPH recirculation for classified suites with controlled fresh-air make-up.
Ventilation AHUs
Fresh-air and make-up units balanced against process exhaust.
Heat recovery (HRV)
Energy recovery on exhaust streams to cut the running cost of high fresh-air loads.
Dehumidifiers (DHU)
Desiccant-rotor units integrated with the AHU to hold low-RH setpoints.
Ducting: precision air distribution
Ductwork engineered to deliver the required air pattern at the lowest operating cost, fabricated with leading-edge sheet-metal profiling technology and leakage-tested before insulation.
| Duct Material | Application | Standards |
|---|---|---|
| GI (galvanized steel) | Standard comfort and process air-conditioning ductwork | ASTM A653 (G90 coating), IS: 277 GSS |
| Aluminium | Cleanroom applications, moisture-laden air, special exhaust | ASTM B209, alloy 1100 / 3003 / 5052 |
| Stainless steel | Kitchen exhaust, fume exhaust, high-moisture systems | ASTM A167, Class 302 / 304, No.4 / 2B finish |
Why our ducting
- Machine-formed profiles and sections for dimensional consistency
- Leakage-tested joints before insulation is applied
- Thermal and acoustic insulation to specification
- Faster fabrication means faster handover
Complete low-side and high-side execution
From desiccant dehumidification for hygroscopic products through to chilled-water plants, pump houses and cooling towers.
Dehumidification (DHU)
Desiccant-rotor dehumidifiers integrated with AHUs to hold precise low-RH setpoints, critical wherever moisture affects product stability, powder flow or hygroscopic materials.
Chilled water plant
Water and air-cooled chillers, insulated CHW headers, balancing valves and energy-efficient pumping systems, sized and commissioned as a system rather than a parts list.
Utility infrastructure
Pump houses, cooling towers, condenser piping and utility distribution, executed and commissioned end-to-end alongside the air systems they serve.
