From shop floor to shipyard

1. Custom ducting fabrication & installation

Spiral and rectangular networks for marine, offshore and industrial HVAC — design, fabrication, thermal insulation, jacketing, testing and commissioning.

• Galvanized iron (GI) — rectangular and spiral with fittings
• Aluminium — light, corrosion-resistant offshore ventilation
• SS304 — heavy-duty hygiene and strength
• Marine SS316L — high corrosion resistance for harsh offshore duty
• FRP & PVC — chemical and wastewater fumes
• Fabric air ducts — even distribution, low dust
• Fiberglass lined / duct boards — acoustic and thermal control
• Heavy-gauge mild steel (3–10 mm) — blast-resistant / load-bearing marine ducts
• Marine large silencer ducts — fan and machinery noise attenuation

2. Ventilation accessories & components

• Volume control, non-return, pressure-relief and manual shutoff dampers (VCD, NRD, PRD, MSD)
• Manual fire dampers (MFD) and inspection hatch covers
• Duct silencers, galley hoods, steam hoods
• Air grilles, defrosting nozzles, punkah louvers, cabin units / pan diffuser boxes
• Louvers, gooseneck and mushroom ventilators, mist eliminators — marine and land plant designs

3–5. Equipment, fluids and refrigerant piping

Placement, piping and commissioning of AHUs, FCUs, air-cooled and water-cooled chillers, condensing units, split and provision refrigeration. Chilled-water pumps, expansion tanks and chemical tanks.

Refrigerant protocol: material selection, line sizing, nitrogen-purged brazing, pressure test, deep vacuum, insulation. Split, multi-split, VRF/VRV and commercial refrigeration.

6. Cold room PU panel supply & install

PU/PIR sandwich panels to layout drawings — drawing review, fabrication, on-site assembly, joint/lock systems and accessories.

7. Marine & industry services

Repair of marine air-conditioning, ventilation, refrigeration and cold rooms. 24-hour service to cut downtime. Custom AC for new-build vessels. Hubs: Port Klang, Malaysia and Tanjong Uncang, Batam.
