Applications
Select an application to see how EcoRec condensers address your specific water and heat recovery requirements.
Paper machine dryer sections exhaust enormous volumes of hot, moisture-laden air. This exhaust represents the single largest thermal energy loss in paper manufacturing. EcoRec direct contact condensers capture water vapour from dryer exhaust hoods, recovering both clean water and latent heat energy. The recovered resources reduce freshwater intake and offset heating costs across the mill.

Paper & Pulp
Key advantages of EcoRec condensers for paper mill water and heat recovery.
Water Reclamation
Recover water vapour from dryer exhaust stacks — reclaiming clean water for reuse in stock preparation, showers, and felt conditioning. Significantly reduces freshwater intake and effluent costs.
Heat Recovery
Capture latent heat from dryer exhaust streams. Pre-heat process water, combustion air, or building heating — cutting gas and steam consumption across the mill.
Fibre-Resistant Design
Self-draining condensate management with advanced weir design prevents fibre buildup common in paper mill environments. Optional CIP system automates cleaning cycles.
Smart Control System
Real-time monitoring with VSD-driven extraction fans automatically adjusts recovery rates based on paper machine speed — maximising efficiency across all production conditions.
Compact Footprint
Vertical design minimises floor space in congested machine halls. Modular construction enables phased installation without extended paper machine downtime.
Long Service Life
High-grade stainless steel tubes with optional corrosion-resistant coatings withstand the humid, acidic conditions in paper mill environments for decades of reliable service.
Your Condenser
Pays You Back
Built-in heat recovery captures waste energy from dryer exhaust condensation and redirects it back into the paper mill — cutting steam costs and reducing freshwater intake.
Dryer Exhaust Becomes
Mill Energy.
Paper machine dryer sections exhaust enormous volumes of hot, moisture-laden air. Instead of venting that thermal energy to atmosphere, our EcoRec condensers capture it and redirect it back into the mill — pre-heating process water, warming combustion air, or supplementing steam systems.
Recovered heat raises incoming water temperatures for stock preparation — reducing steam consumption in chest heating and dilution water systems.
Warm incoming combustion air for bark, recovery, or gas boilers — improving thermal efficiency and reducing supplementary fuel consumption.
Generate heated water from waste heat for paper machine shower systems — displacing steam-heated shower water and reducing steam demand.
Low-grade recovered heat feeds into mill building heating — reducing winter heating costs across machine halls, warehouses, and offices.

FAQs
Common questions about EcoRec condensers for paper and pulp industry water and heat recovery.
The EcoRec self-draining weir design and direct contact condensation process are specifically engineered to handle fibre-carrying exhaust. Fibres are captured in the condensate stream and removed via the drainage system. Optional CIP cleaning cycles prevent any long-term buildup, and the modular design allows easy access for maintenance.
Recovery volumes depend on dryer section size and production speed, but typical paper mill installations recover 70–80% of water vapour from dryer exhaust. For a medium-speed paper machine, this can equate to tens of thousands of litres per day of clean water reclaimed for mill reuse.
Yes. The smart control system with VSD-driven extraction fans continuously monitors exhaust conditions and automatically adjusts condensation rates to match paper machine speed. This ensures optimal recovery at all production levels without manual intervention or process disruption.
EcoRec condensers are designed for retrofit installation with minimal production impact. The modular design allows pre-assembly off-site, with typical on-site installation and commissioning completed during a planned maintenance shutdown of 3–5 days.
All EcoRec models use high-grade stainless steel tubes with carbon steel shells and optional corrosion-resistant coatings. The materials are specifically selected to withstand the acidic, high-humidity environment common in paper mill dryer sections, ensuring long service life and minimal maintenance.
Most paper mill installations achieve full payback within 12–18 months through combined water savings, reduced energy consumption, and lower effluent treatment costs. Mills with high freshwater costs or strict discharge limits see the fastest returns.
