Solutions for
Maximum Heat Recovery
At Ecoonex, we specialize in recovering heat from any flue gas or waste stream, including those previously considered too challenging or corrosive for conventional systems. With our proprietary EcooPure™ technology, we recover energy far below the acid and water dew points, maximizing efficiency and unlocking new potential for heat reuse.
Whether it’s a refinery, biomass plant, steel mill, or dryer, our solutions adapt to the toughest environments—from ultra-low to extremely high temperatures—delivering performance, durability, and proven energy savings.
The Ecoonex Plate-Type Air Preheater delivers high thermal efficiency in a compact and robust design. Heat is transferred between two fluids via flat or enhanced plates, with the entire plate surface acting as active heat-transfer area.
Key features:
- Compact footprint compared to tubular or regenerative systems
- Uniform flow distribution with low bypass risk
- Controlled metal temperatures to remain above the acid dew point
- Wide material selection for temperature and corrosion resistance
- Optional patterned or ribbed plates to increase turbulence and heat-transfer coefficients
- Temperatures up to 1000°C / 1832°F
Ecoonex gas-to-gas heat exchangers are engineered for high-temperature, dust-laden exhaust streams where reliability, low fouling, and long operating life are essential.
Unlike conventional designs, Ecoonex solutions are optimized to handle high particulate loading without performance degradation. Carefully engineered flow paths, smooth or controlled-profile heat-transfer surfaces, and uniform velocity distribution minimize dust deposition and prevent local hot spots.
Key advantages include:
- Low fouling tendency even at elevated dust concentration
- Stable performance at high temperatures, suitable for fired heaters, furnaces, and process exhausts
- Robust mechanical design for thermal cycling and pressure fluctuations
- Controlled metal temperatures to stay above acid dew point where required
- Easy online or offline cleaning, including soot blowing or water washing
The Ecoonex Tubular Air Preheater uses straight or finned tubes to transfer heat between gas and air or liquid streams. This design is well suited for high temperatures, high pressures, and applications requiring mechanical robustness.
Key features:
- Suitable for Air–Steam, Air–Water, Air-Glycol or Air –Oil service
- Flexible tube layouts and materials
- Proven and familiar design for many operators
- Can be combined with plate-type exchangers for hybrid solutions
- Codes: ASME VIII/Div1, PED, ASME I, TSSA / CRN
Ecoonex Economizers recover waste heat from flue gas to preheat boiler feedwater, process water, or other liquid streams—improving overall plant efficiency and reducing fuel consumption.
Key features:
- Designed for clean or corrosive flue gases
- Available in metallic or glass-coated execution
- Fully integrated with cold and hot air preheaters if required
- Suitable with DeNOx window
Ecoonex Flue Gas Coolers enable deep cooling of exhaust gases—often below the water and acid dew points—to recover both sensible and latent heat.
Key features:
- Maximum heat recovery, including condensation heat
- Designed for acidic condensate environments
- Can be integrated with neutralization and water-reuse systems
- Suitable for ultra-low stack temperatures
PolyMore™ is Ecoonex’s platform for polymer-based and Glass-Enameled heat-recovery technology, developed specifically for highly corrosive flue-gas environments.
PolyMore exchangers are typically applied in the cold end of heat-recovery systems where metallic solutions reach their corrosion limits.
Key features:
- Excellent resistance to sulfuric acid, chlorides, and halogens
- Suitable for operation below the acid and water dew points
- Low fouling tendency and smooth internal surfaces
- Long lifetime with minimal maintenance
Our flagship system for deep flue gas cooling, EcooPure™ enables heat recovery below dew point temperatures with mist-free operation. It's ideal for projects focused on maximum energy recovery and corrosion resistance, particularly when acidic components like H2SO4, SO₃, HF or HCl are present.
ModuLuvo™ – Modular Heat-Recovery Architecture
ModuLuvo™ is Ecoonex’s modular heat-exchanger architecture, designed to deliver maximum flexibility, scalability, and reliability in demanding heat-recovery applications.
Rather than a fixed exchanger geometry, ModuLuvo is a building-block concept: standardized, interchangeable heat-exchange modules are combined into a tailored system that matches the required duty, corrosion resistance, temperature level, and layout constraints.
This approach allows Ecoonex to integrate different PolyMore technologies—including PolyMore-EB, PolyMore-P, and PolyMore-PGF—into one coherent, optimized heat-recovery solution.
- Fully modular design – standardized exchanger modules assembled into a custom configuration
- Scalable capacity – add or remove modules as process conditions change
- Mixed-material integration – combine polymer, glass-enameled, or metallic sections in one system
- Easy transport and installation – smaller modules instead of large monolithic units
- Simplified maintenance – individual modules can be isolated or replaced
- Future-proof design – upgrades without complete system replacement
Optimized for Corrosive and Condensing Service
ModuLuvo is particularly suited for corrosive flue-gas applications, where different temperature zones require different materials.
By assigning the right material to the right temperature zone, ModuLuvo maximizes lifetime while minimizing CAPEX and OPEX.
Typical configuration examples:
- Hot end: PolyMore-EB (enamel-coated bundles) for high-temperature, acid-resistant service
- Intermediate zone: PolyMore-PGF or PolyMore-P for corrosion-resistant gas-to-gas or gas-to-liquid
- Cold end: Polymer or condensing modules operating safely below the acid dew point
Our solutions are used across a wide range of industrial sectors, including:
