Engineering FAQ
1. Strategic Scope & Regional Decarbonization Mandate
With Southeast Asia’s industrial manufacturing corridors facing stringent Scope 1 decarbonization mandates and Net-Zero commitments towards 2050, industrial thermal electrification has rapidly transitioned from an optional sustainability initiative into an indispensable operational imperative. Industrial facilities across Vietnam, Thailand, and Indonesia generate millions of gigajoules of low-grade waste heat daily through cooling towers, pasteurization loops, washing effluents, and vapor exhausts, while simultaneously combusting expensive fossil fuels to produce low-pressure process steam.
Conventional fossil fuel boilers—relying on coal, heavy fuel oil (FO/DO), or liquefied natural gas (LNG/LPG)—expose plant operations to extreme global fuel price volatility, supply chain disruptions, and emerging carbon taxation penalties. Through this landmark bilateral alliance, Lecoqimex has entered into an exclusive master distribution and process engineering integration partnership with Skyven Technologies (USA) across Vietnam, Thailand, and Indonesia.
Our combined engineering mandate delivers turnkey thermal integration: from comprehensive on-dock thermodynamic audits and high-fidelity pinch analysis simulations, to custom skid modularization, turnkey commissioning, and performance-guaranteed energy contracting through our specialized Turnkey EPC & Modernization Solutions.

2. ArcaHeat™ Thermodynamic Architecture & Low-GWP Refrigerant Engineering
The Skyven ArcaHeat™ system utilizes advanced multi-stage thermodynamic vapor recompression cycles (MVR/VRC) capable of capturing low-grade industrial heat (40°C – 85°C) and temperature-amplifying it into dry, saturated process steam at temperatures reaching up to 140°C (up to 3.61 bar(g) holding pressure).
Every system engineered under this partnership is custom-simulated using high-fidelity CFD (Computational Fluid Dynamics) and rigorous HTRI Xchanger Suite calculations. Lecoqimex application engineers optimize plate surface corrugation angles and channel geometries, maintaining single-phase fluid pressure drop below 0.35 bar while achieving overall heat transfer coefficients (U-values) exceeding 3,800 – 4,500 W/m²·K.
In full compliance with the Kigali Amendment and European F-Gas regulations, the ArcaHeat™ platform incorporates ultra-low Global Warming Potential (GWP < 1) hydrofluoroolefins (HFOs) and natural hydrocarbon refrigerant blends. These working fluids feature zero Ozone Depletion Potential (ODP = 0) and high critical temperature points, eliminating high-pressure stability hazards during severe thermal shock or sudden utility trips.

4. Concrete Industrial Use Cases & Thermal Simulation
Case 1: Dairy & Beverage Pasteurization & CIP Loop (Binh Duong, Vietnam)
A large multinational dairy packaging facility operated three steam-jacketed pasteurizers and a continuous Clean-In-Place (CIP) sanitation line requiring continuous 125°C steam at 2.2 tons/hour. The facility dumped 48 m³/hour of pasteurizer cooling discharge and hot CIP rinse effluent at 62°C directly to the wastewater treatment holding basin.
- Integration Scheme: Lecoqimex engineered a dual-skid Skyven ArcaHeat™ system using laser-welded plate evaporators that extracted 1.85 MW_th from the 62°C wastewater, returning chilled water at 38°C back to the process pre-cooling stage.
- Performance Results: Generated 2.4 tons/hour of 132°C steam at an audited operational COP of 3.84.
- Economic & ESG Impact: Displaced 1,650 tons/year of heavy fuel oil, saving $392,000 USD/year in net energy bills and cutting 4,850 metric tons of annual CO₂ emissions. Simple payback was achieved in 21.4 months.
Case 2: Textile Dyeing & Stenter Frame Heat Recovery (Rayong, Thailand)
A high-throughput polyester and cotton fabric dyeing mill consumed significant LNG to supply 3.5 bar(g) steam to dyeing autoclaves and cylinder dryers. The wash-water rinse streams released 65 m³/hour at 71°C.
- Integration Scheme: Installation of a high-temperature ArcaHeat™ unit utilizing specialized titanium plate heat exchanger cassettes to resist corrosive dyestuff chlorides.
- Performance Results: Lifted thermal energy from 71°C to produce 138°C saturated steam with a seasonal COP of 4.18.
- Economic & ESG Impact: Reduced plant-wide natural gas expenditure by 43%, delivering $480,000 USD in audited annual OPEX savings while ensuring full compliance with the European Union’s product carbon footprint thresholds for export textiles.
5. Carbon Economics, CBAM Export Readiness & OPEX Analysis in ASEAN
Export-oriented manufacturing enterprises in Vietnam, Thailand, and Indonesia face critical market access barriers under the European Union Carbon Border Adjustment Mechanism (CBAM) and international supply-chain ESG audits (such as Apple Clean Energy Program, Nike Supplier Climate Goals, and RE100). Scope 1 emissions from industrial steam boilers are the primary culprit behind high embodied carbon intensity in metals, chemicals, fertilizers, packaging, and textiles.
Electrifying industrial steam via Skyven ArcaHeat™ heat pumps eliminates direct combustion emissions at the factory gate. When paired with on-site rooftop solar photovoltaic (PV) arrays or green power purchase agreements (DPPA), the generated process steam reaches near-zero lifecycle carbon intensity (< 5 g CO₂e/kg steam).
The Financial Formula of COP 3.8 Industrial Heat Pumps:
At an electricity tariff of $0.078/kWh and an operating COP of 3.80, the effective cost to generate 1 MWh_thermal of steam is approximately $20.50 USD. In comparison, generating 1 MWh_thermal via Heavy Fuel Oil (FO at $0.58/kg) costs over $58.00 USD, and via LNG (14.5 USD/MMBtu) costs over $54.00 USD. This delivers an immediate 60% – 65% reduction in steam OPEX.

7. Frequently Asked Questions (Technical & Financial FAQ)
Direct answers to top engineering, integration, and financial payback questions for industrial plant directors and utility engineers.
Q1: What is the minimum waste heat temperature required to produce 140°C steam?
The Skyven ArcaHeat™ system operates efficiently with liquid heat sources starting at 40°C. However, the optimal economic performance (COP between 3.5 and 4.5) is achieved when waste heat is available between 55°C and 85°C, which is common in pasteurizer effluents, condenser loops, and dryer exhaust streams.
Q2: Can ArcaHeat™ operate alongside our existing fossil fuel boilers without shutdown?
Yes. ArcaHeat™ is modular and engineered specifically for hybrid baseload integration. It connects directly into your existing steam header through an automated check/modulating valve station, acting as the primary baseload generator (70–90% demand). Existing fossil boilers remain on modulated standby for peak surges, requiring zero plant shutdown during tie-in.
Q3: How does Lecoqimex conduct on-site thermal audits before project commitment?
Our engineering team installs ultrasonic flowmeters and calibrated temperature dataloggers on your thermal lines for 7–14 days. We then build an exact HTRI/CFD thermodynamic model and deliver an investment-grade audit detailing guaranteed COP, steam output rates, and certified payback projections prior to contract signing.
Q4: What maintenance is required for high-temperature steam heat pumps?
Because ArcaHeat™ uses hermetic/semi-hermetic recompression stages and automated CIP backflushing on heat exchangers, routine maintenance is minimal. It is restricted to annual lube oil sampling, filter replacement, and instrument calibration, all covered under Lecoqimex’s 24/7 SLA maintenance contracts.
