Product Types in Stock

Gulf Union Ozone stocks six compressed air treatment product families to ISO 8573 air quality standards, with PED and ASME VIII documentation for vessels — covering every stage from bulk water removal to ultra-dry instrument-air quality for Saudi Arabia industrial plants.

Type 01

Refrigerated Air Dryers (Cycling & Non-Cycling)

Refrigerated compressed air dryers for bulk moisture removal, achieving a pressure dew point (PDP) of +3°C to +10°C — corresponding to ISO 8573 Class 4 air quality. Non-cycling models (constant refrigeration) for steady baseload; energy-saving cycling models with thermal mass (glycol or phase-change mass) for variable duty common in Saudi manufacturing and workshop applications. Capacity range: 10 m³/h to 5000 m³/h (models stocked from 10 to 500 m³/h; larger by order). Aluminium heat-exchanger internals with stainless steel refrigerant system; automatic float-type condensate drain. Refrigerant R-410A or R-134a. Maximum inlet temperature: 45°C standard, 60°C high-temperature models. Operating pressure to 13 bar. Integrated pre-cooler and after-cooler.

Type 02

Heatless Desiccant Air Dryers

Twin-tower heatless desiccant dryers using silica gel or activated alumina desiccant beds to achieve pressure dew points of -40°C (ISO 8573 Class 2) — the standard for instrument air on pneumatic control valves, positioners, and actuators at Saudi Arabia oil & gas, petrochemical, and power generation facilities. Automatic timed or dew-point-controlled switching between towers (typically 5-minute cycle). Purge air consumption approximately 15–20% of rated inlet flow for bed regeneration. Silica gel standard; activated alumina for high-humidity tropical climates; molecular sieve 4A for -70°C PDP (Class 1) heatless option (higher purge loss). Capacity range 10 m³/h to 1000 m³/h. Carbon steel or aluminium pressure vessels; SS 316L piping. PED certified. Integral pre-filter and after-filter connections.

Type 03

Heated Desiccant Air Dryers (Blower-Purge & Zero-Purge)

Energy-efficient heated desiccant dryers achieving -40°C to -70°C PDP (ISO 8573 Class 1/2) with significantly lower purge air loss compared to heatless types — preferred for large instrument air systems above 200 m³/h where energy savings justify the additional capital cost. Blower-purge (externally heated) design draws ambient air via blower fan through an electric heater to regenerate the off-line desiccant tower — zero compressed air purge loss. Zero-purge (internally heated) type uses an immersion heater inside the desiccant bed with a partial closed-loop regeneration — virtually zero purge loss. Heat of compression (HOC) models use waste heat from the compressor discharge. Molecular sieve 4A desiccant standard. PED; ASME option. Capacity range 100 m³/h to 5000 m³/h.

Type 04

Coalescing Filters (Pre-Filter & High-Efficiency)

Multi-stage compressed air coalescing filter housings to ISO 8573 for removal of oil aerosols, water aerosols, and particulate contamination at each stage of the treatment train. Grade F pre-filter: 3 micron particulate, 0.8 mg/m³ oil residual — protects the dryer. Grade C coalescing filter: 1 micron, 0.1 mg/m³ oil residual — post-dryer protection. Grade D high-efficiency coalescing filter: 0.01 micron, 0.01 mg/m³ oil residual — meets ISO 8573 Class 1 oil content for instrument air. Filter element medium: borosilicate glass microfibre with outer polypropylene retaining sock; aluminium die-cast housing with stainless internals. Sizes DN15 to DN200 (1/2" to 8"). Differential pressure indicator standard; auto-drain models. Element change interval 6000–8000 hours.

Type 05

Activated Carbon Adsorbers & Odour Removal Filters

Grade V activated carbon adsorbers for removal of residual oil vapour and hydrocarbon odours from compressed air downstream of coalescing filtration — achieving ISO 8573 Class 1 oil vapour content (<0.003 mg/m³ as n-hexane equivalent). Essential for breathing air systems, paint spray applications, pharmaceutical fill lines, food and beverage contact air, and instrument air used in sensitive process analysers. Granular activated carbon (coconut-shell base) in aluminium or stainless steel housing; typical bed depth 200–400 mm; service life approximately 2000–4000 hours depending on upstream oil loading. Carbon cartridges supplied separately for on-site replacement. Integral differential pressure gauge. Sizes DN15 to DN100 (1/2" to 4"). Rated to 16 bar.

Type 06

Compressed Air Receivers (Storage Vessels)

ASME Section VIII Division 1 compressed air receivers (air storage tanks) for system volume buffering, pulsation dampening, and peak demand management in Saudi Arabia industrial compressed air systems. Vertical floor-standing models: 50 L, 100 L, 200 L, 500 L, and 1000 L at MAWP 10–16 bar. Horizontal skid-mounted models: 1500 L, 2000 L, and 3000 L. Carbon steel SA-516 Gr.70 shell and heads with internal epoxy coating; stainless steel SS 316 models for clean air and food/pharmaceutical. Supplied with ASME 'U' stamp, full ASME Data Report, NBIC National Board registration number, spring-loaded safety relief valve, isolation valve, drain valve, pressure gauge, and inspection ports. European PED models also available with CE mark.

FAQ

Frequently Asked Questions — Air Dryers & Compressed Air Treatment Saudi Arabia

What is the difference between refrigerated and desiccant air dryers for Saudi Arabia plants?

Refrigerated air dryers cool compressed air to approximately +3°C PDP — suitable for ISO 8573 Class 4 or 3 instrument air where a +3°C dew point is acceptable. They are energy-efficient and low-maintenance. Desiccant air dryers (heatless or heated) use silica gel or molecular sieve beds to achieve PDP of -40°C to -70°C — essential for ISA Class 1 instrument air, pneumatic control systems on critical control valves, and applications where condensation must be prevented. Gulf Union Ozone stocks both types in Jeddah for same-day dispatch across Saudi Arabia.

Which ISO 8573 air quality class do your compressed air dryers achieve in Saudi Arabia?

Our refrigerated dryers achieve ISO 8573 Class 4 (PDP +3°C) or Class 3. Heatless desiccant dryers achieve Class 2 (PDP -40°C). Heated desiccant dryers achieve Class 1 (PDP -70°C) for critical instrument air in Saudi Aramco, SABIC, and SWCC facilities. Combined treatment trains of pre-filter + refrigerated dryer + coalescing filter + activated carbon adsorber + after-filter achieve ISO 8573 Class 1:2:1 for the highest-purity applications. Full dew-point test certificates supplied with every system.

Do you supply ASME VIII compressed air receivers for Saudi Arabia industrial facilities?

Yes. Gulf Union Ozone supplies compressed air receivers to ASME Section VIII Division 1 in sizes from 50 litres to 3000 litres, MAWP 10–16 bar. Carbon steel SA-516 Gr.70 with internal epoxy coating standard; SS 316 for clean and food-grade air.
