Compressed Air, Vacuum & Engineered Equipment

Compressed air dryers remove water vapour to prevent corrosion, contamination, and process failures. Refrigerated dryers cool air to precipitate moisture; desiccant dryers adsorb moisture onto a desiccant bed for lower dew points.

Refrigerated Dryer — PDP

+3°C pressure dew point (standard)

Desiccant Dryer — PDP

−20°C to −70°C pressure dew point

Desiccant Types

Heatless (purge), heated (internal/external), blower-purge (zero-loss)

Capacity Range

10 Nm³/hr to 10,000 Nm³/hr

Inlet Pressure

7 bar to 16 bar

ISO 8573-1 Class

Class 1–3 (moisture) achievable depending on dryer type

Filtration protects downstream equipment and ensures air quality compliance. We size filter trains based on the ISO 8573-1 air quality class required for the application, not a generic catalogue recommendation.

Pre-filter (General Purpose)

Removes particles ≥1 µm, oil aerosol ≤0.5 mg/m³

Coalescing Filter (High Efficiency)

Removes particles ≥0.01 µm, oil aerosol ≤0.01 mg/m³

Activated Carbon Filter

Oil vapour removal ≤0.003 mg/m³; odour removal

Particulate Filter

Sterile-grade: 0.01 µm absolute for pharma/food

Pressure Drop

<0.2 bar (clean element); replacement interval as per manufacturer

Brands

Summits Hygronics, Trident, Parker Hannifin (on request)

We supply rotary screw compressors from multiple manufacturers and provide service support for Atlas Copco equipment. Selection is based on duty cycle, air quality requirements, energy efficiency targets, and site conditions.

Power Range

5 kW to 250 kW (larger on enquiry)

Output Pressure

7 bar / 10 bar / 13 bar standard; up to 40 bar on request

Drive Type

Fixed speed (DOL/star-delta) and variable speed drive (VSD)

Oil-Injected

Standard lubricated screw; ISO 8573-1 Class 1 with downstream filtration

Oil-Free

Class 0 oil-free (certified oil-free per ISO 8573-1) for pharma/food

Brands

Atlas Copco (service & supply), Summits Hygronics, Elgi, Trident

Correct piping design is as critical as correct equipment selection. Undersized or poorly designed distribution causes pressure drop, water carryover, and energy waste. We calculate pressure drop to specification and install using appropriate materials.

Aluminium Loop Piping

DN 15 to DN 200; push-fit modular system; low pressure drop

Stainless Steel Piping

SS 316L for pharma, food, and high-purity applications

GI / MS Piping

General industrial; hot-dip galvanised for corrosion resistance

Design Basis

Pressure drop <0.1 bar across distribution; velocity <6 m/s

Scope of Work

Pipe sizing, isometric drawing, supply, erection, pressure test, commissioning

Pressure Test

Pneumatic test at 1.1× working pressure per installation standard
