Country Overview: Power & Infrastructure
Vietnam, with a population of 100 million and one of the world’s fastest-growing manufacturing economies, is rapidly industrializing but struggles with an unreliable power grid. According to Vietnam Electricity (EVN), the country experienced rolling blackouts across northern industrial zones in 2023 and 2024, with the power shortage reaching 4,350 MW during peak demand periods. This has driven a massive expansion in captive diesel generation among industrial manufacturers.
The manufacturing sector — textiles, footwear, electronics, furniture — and the agricultural processing industry (rice, coffee, aquaculture) are Vietnam’s two largest consumers of industrial diesel generators. Industry estimates suggest that Vietnam’s industrial sector operates over 25,000 diesel generator sets above 100 kVA, with the Mekong Delta alone hosting thousands of units for irrigation pumping stations. Huaquan Power entered Vietnam in 2019 through a partnership with a Ho Chi Minh City-based industrial equipment distributor.
Case Study 1: Textile Export Factory — Binh Duong Industrial Zone
Customer Profile
A South Korean-owned textile export factory in Binh Duong Industrial Zone (HCMC Metro), producing 12 million meters of fabric annually for the US and European markets. The factory operates 24/7 with 8 Weichai WD618C3-15 generators (400 kVA each) plus 4 Cummins 6CTA8.3-G2 units (200 kVA each) for finishing lines. The Binh Duong industrial zone experiences 4–6 power cuts per month during dry season, each lasting 3–8 hours.
Challenge
The factory’s maintenance team was sourcing parts from multiple distributors in HCMC, resulting in inconsistent quality and parts incompatibility. The primary issue was variably sourced fuel injectors for Weichai WD618 engines — the factory had mixed three different aftermarket brands, causing uneven fuel delivery, smoke, and premature carbon buildup. The factory needed a single, reliable source for standardized Weichai and Cummins parts with traceability.
Solution
Huaquan Power standardized the factory’s parts inventory:
– Fuel Injectors: Weichai WD618 612630020057 (64 pcs) — standardized to Weichai OEM specification, individually flow-tested.
– Fuel Pumps: Weichai WD618 612630020056 (8 pcs).
– Cylinder Head Gaskets: Weichai WD618 612630020055 (16 pcs).
– Oil Filters: Weichai WD618 612630020058 (240 pcs).

– Parts procurement cost reduced 25% vs. multi-distributor sourcing.
– Factory signed a 2-year exclusive parts supply agreement with Huaquan.
Case Study 2: Electronics Manufacturing Plant — Bac Ninh Industrial Zone
Customer Profile
A Japanese-owned electronics assembly plant in Bac Ninh (near Hanoi), producing precision PCB assemblies for consumer electronics. The plant operates in a clean-room environment with 4 Perkins 2206A-E13TAG2 generators (400 kVA each) providing backup power for temperature/humidity-controlled clean rooms and precision SMT equipment. Power quality is critical — voltage dips below ±5% can damage PCB assembly processes costing USD 25,000 per incident.
Challenge
The plant’s existing maintenance contract with a Singapore-based supplier was costing USD 180,000/year for 4 generators, with lead times of 25–30 days from Singapore warehouse. When the supplier announced a 22% price increase in 2025, the plant’s procurement manager sought alternatives. Additionally, the plant needed Perkins-specific parts for 30,000-hour major service on two of the four engines.
Solution
Huaquan Power provided a Perkins 2206A-E13TAG2 overhaul package:
– Cylinder Head Gaskets: Perkins 3681A031 (8 pcs).
– Fuel Injectors: Perkins 2645A202 (16 pcs).
– Fuel Pumps: Perkins 2641365 (4 pcs).
– Piston & Ring Sets: Perkins 2481532 (8 sets).
– Cylinder Liners: Perkins 2481531 (8 pcs).
– Main Bearing Sets: Perkins 2481533 (4 sets).
– Connecting Rod Bearings: Perkins 2481534 (4 sets).
– Turbochargers: Perkins 178651 (4 pcs).
– Water Pumps: Perkins 4133A018 (4 pcs).
– Oil Coolers: Perkins 4133A019 (4 pcs).
– Oil Filters: Perkins 2485519 (120 pcs).
– Fuel Filters: Perkins 26560145 (120 pcs).
– Air Filters: Perkins 26510333 (60 pcs).
– AVR: Basler DECS-100 (4 pcs) — for precision voltage regulation.
– Voltage Sensors: 4 sets.
– Complete Gasket Kits: Perkins T408373 (4 kits).
Results
– Two engine overhauls completed within 10 days by local maintenance crew.
– Annual parts cost reduced to USD 108,000 (40% below Singapore supplier).
– Zero voltage stability incidents in the 12 months following overhaul.
– Plant signed 3-year annual maintenance package with Huaquan.
Case Study 3: Mekong Delta Irrigation Pump Station — Can Tho
Customer Profile
A state-operated irrigation pump station in Can Tho, Mekong Delta, serving 8,000 hectares of rice paddies across three districts. The station operates 6 Weichai WD12C420-15 generator sets (420 kVA each) powering 12 electric irrigation pumps during the dry season (November–April). The Mekong Delta’s saline intrusion problem has worsened in recent years, making reliable pump operation existential for rice farmers.
Challenge
The pump station had been operating with minimal spare parts inventory due to budget constraints. When three Weichai WD12 fuel pumps (Weichai 612630020056) and two turbochargers (Weichai 612630020061) failed simultaneously in December 2025 during peak irrigation season, the station faced the prospect of losing 3,000 hectares of winter-spring rice crop. The nearest Weichai dealer in HCMC quoted 6-week delivery and USD 42,000 for the emergency parts package.
Solution
Huaquan Power expedited an emergency parts shipment via air freight:
– Fuel Pumps: Weichai 612630020056 (6 pcs) — air freight, 5-day delivery.
– Turbochargers: Weichai 612630020061 (4 pcs) — air freight.
– Fuel Injectors: Weichai 612630020057 (24 pcs).
– Oil Filters: Weichai 612630020058 (60 pcs).
– Fuel Filters: Weichai 612630020059 (60 pcs).
– Air Filters: Weichai 612630020060 (30 pcs).
– Water Pumps: Weichai 612630020062 (4 pcs).
– Cylinder Head Gaskets: Weichai 612630020055 (12 pcs).
– AVR: SX460 (10 pcs) for pump station alternators.
Air freight cost was higher but still USD 18,600 total — 56% below the HCMC dealer quote.
Results
– Air-freighted parts arrived on Day 5; all 6 generators operational by Day 8.
– Zero crop loss attributed to pump station downtime.
– Total cost USD 18,600 vs. dealer quote USD 42,000 (56% savings).
– Pump station pre-ordered dry season parts inventory for 2026 at USD 35,000.
