Our HVAC Services

Three integrated capabilities under one roof: engineering, manufacturing, and equipment supply — so your HVAC project has a single accountable partner.

1. HVAC System Design & Build (EPC)

We take HVAC projects from concept to commissioning. Our strong in-house engineering team allows us to undertake full EPC (Engineering, Procurement & Construction) projects — we design systems in 3D, matched to your building's load and budget, then fabricate and install them with our own teams.

  • Chiller plant specialist — including installation of 4 × 1,650 TR units at Indonesia's tallest building (Thamrin Nine)
  • VRV / VRF systems for offices, hotels, campuses and mixed-use buildings
  • Heat load calculation, 3D/BIM ducting design and equipment selection
  • Installation, testing, commissioning and balancing
  • Related building systems on EPC projects: plumbing and FM200 fire suppression
  • Experience across retail, healthcare, refineries, data centers, airports and power plants

2. Square & Spiral Duct Manufacturing

Our core strength. We fabricate ducting in-house at our 4,500 m² Jakarta workshop using automated production lines — giving you consistent quality, fast lead times and competitive pricing.

  • Square duct & spiral duct, fabricated to project specification
  • Galvanized steel (BJLS) — Fumira, Lokfom and Sarana sheet brands
  • Stainless steel square and spiral duct for hygienic and special applications
  • Connection systems: Sisipan, TDF and TDC — including TDF/TDC corners
  • Produced on auto-line forming, transverse flanging, Pittsburgh lock and spiral duct machines
