Heat Pump-Based Heat Recovery Systems

ENEVA heat pump-based heat recovery systems are advanced engineering solutions designed to capture low-temperature waste heat—often considered uneconomical—and upgrade it to usable temperature levels for reintegration into industrial processes. They are especially effective in facilities with high-flow, low-temperature waste heat streams where conventional recovery methods are insufficient.

Recovery of low-temperature waste heat
Temperature boost via heat pump technology
Process-specific integration and system engineering
Reduces energy costs and fuel consumption

WHAT IS HEAT PUMP-BASED RECOVERY?

In many industrial facilities, exhaust gases, wastewater, or process air are released to the atmosphere at high flow rates but low temperatures. These temperature levels are often insufficient for traditional heat exchangers or waste heat boilers.

Low temperatures are elevated using a heat pump
The recovered energy becomes reusable
Additional fuel consumption is minimized

This approach provides a high-level solution for energy efficiency.

WHICH WASTE HEAT SOURCES CAN BE UTILIZED?

Waste process gases and process air
Exhaust from drying and baking lines
Processes with simultaneous heating and cooling
Low-temperature flue gases
Cooling tower streams

Waste heat is collected via specially designed heat exchangers
The collected energy is transferred to the heat pump
Temperature is raised to a usable level
The generated heat is used for process air or another fluid
The system operates in a closed loop with automatic control

Chemical and process industries
Food and drying facilities
Energy-intensive production lines
Continuously operating industrial plants
Applications with low-temperature waste heat potential

REFERENCE APPROACH

ENEVA implements heat pump-based recovery solutions under the EPC model, delivering end-to-end—from concept development to commissioning. This ensures economically and sustainably reclaiming energy otherwise lost at low temperatures.
