PULP & PAPER
Your Path to Decarbonization powered by HEATEN’s High-Temperature Heat Pumps
Decarbonize your processes with our highly efficient and flexible technology!
INDUSTRIAL HEAT PUMPS BUILT ON PROVEN PISTON TECHNOLOGY
Reliable technology to replace fossil fuels
Pulp & paper is one of the most energy-intensive industrial sectors. HEATEN high-temperature heat pumps recover mill heat and deliver useful process heat up to 200°C - while also providing industrial cooling where needed. This dual capability reduces energy use, Scope 1 emissions, and dependency on water-intensive cooling towers.
Thermal energy can be up to ~60% of production costs, while conventional boiler systems often run ~70 - 85% efficiency and dump valuable heat through exhaust and condensate. High-temperature heat pumps can reach COPs (coefficients of performance) ~2 - 7 in relevant lifts - turning waste heat into stable, electrified process heat and reducing primary energy use significantly.
Integrate HEATEN HeatBoosters into Your Process
• Heat sink: 90–200°C (water or steam)
• Heat source: 10–150°C (water or steam)
• Part-load performance: down to ~20% load
• Modular scale: 1–50+ MWth via parallel/cascaded installations
• Impact highlights: up to 85% energy savings, up to 12,000 t CO₂ reduction/year, up to 40,000 m³ potential water savings/year

The benefits at glance
Heating and Cooling – One Integrated System
In pulp & paper, stable temperatures are essential - not only for drying, but also for biological processes in white water and wastewater systems. If temperatures rise too high, bacterial activity and process stability can suffer.
HEATEN's high-temperature heat pumps integrate heating and cooling in one system. Waste heat is recovered and upgraded to useful process heat, while the heat source is actively cooled-down.
Stepwise Integration with Minimal Production Disruption
HeatBooster can be installed alongside existing steam systems, allowing production to continue during integration. After validation, steam load is shifted gradually - reducing operational risk. Its modular design enables projects to start with a MW-scale pilot and expand step by step toward larger capacities, avoiding a high-risk “big bang” transition.
Reduce Scope 1 emissions from steam — without rebuilding your mill.
For many paper mills, the boiler is still a major source of direct emissions. HEATEN high-temperature heat pumps recover waste heat from sources such as dryer hoods, exhaust air, and warm water loops, and upgrade it into useful process heat up to 200°C. The result: lower fossil fuel demand, lower Scope 1 emissions, and a practical path to decarbonization with less disruption to mill operations.
REDEFINING WASTE HEAT
Where HeatBooster
fits in a pulp & paper mill
Dryer section:
tissue, paper, board
White water & process water heating
Upgrade low-temperature heat to cover stable hot-water demand.
Hot water for showers, cleaning and utilities
Supply reliable high-temperature water without extra boiler load.
Preheating for air and feedwater systems
Lift recovered heat to reduce steam demand in heaters and preheaters.
Low to medium temp. steam
Support steam networks by reducing the boiler’s base load - especially where up to 200°C heat makes electrification feasible.
WHAT TO KNOW ABOUT THE TECHNOLOGY BEHIND OUR INDUSTRIAL HEAT PUMP?
How it works
-
Reduce the temperature lift - boosts efficiency
Higher source temperatures and lower required process temperatures improve heat-pump performance — think dryer hood vapour dewpoint ≥ 60°C as a strong source candidate.
-
Recover heat from drying hood exhaust
Take the hot, humid air leaving the dryer and capture its heat (both the heat in the air and the heat in the water vapor). That recovered heat is transferred into a warm-water loop that the heat pump can then “boost” to useful process temperatures.
-
Bottom cycle: create usable heat
HeatBooster lifts recovered warm water to high-temperature process heat—feeding hot-water loops directly or supplying steam via a steam generator, depending on the mill. The solution is modular, so it scales from single units to larger engineered systems.
-
Top cycle: keep steam stable - even at part load
HeatBooster is designed for excellent part-load performance, allowing it to respond efficiently to non-steady process conditions and frequent load changes. This enables more dynamic operation with higher cycling tolerance, stable pressure and temperature control, and efficient steam supply even when production ramps up or down, while reducing boiler load.
