The paint line heat recovery system reuses the furnace's residual heat

For Scanfil's new Gema automatic paint booth, we implemented a two-stage heat recovery system together with a ventilation unit featuring cooling capability. The residual heat released from the oven, which previously went to waste, is now directed into the central heating system of the production facilities and also covers the energy requirements of the added system. According to the forecast, the investment will pay for itself in approximately five years.

Project challenge

The oven emitted a significant amount of surplus heat, which was previously released directly into the outdoor environment and wasted. At the same time, the client wanted to improve working conditions for employees and ensure a continuous supply of fresh air to the paint shop and a cooler indoor climate during the summer.

How we built it

We reached a joint decision with the client to make use of the residual heat emitted by the oven by directing it through the central heating system of the production facilities. We implemented a two-stage heat recovery system together with a ventilation unit, to which a cooling capability was also added to improve the indoor climate in summer.

FAQ

Frequently asked questions

How is the oven's waste heat reused?
The waste heat from the oven is directed into the central heating system of the production facilities via a two-stage heat recovery system. Previously this heat was released directly to the outside environment and wasted.
How quickly does the investment pay off?
According to budget calculations, the investment pays for itself in approximately five years.
Does the system also improve the indoor climate in summer?
Yes, a cooling function was added to the ventilation unit to improve the summer indoor climate. All supply air is directed to the workers' area, ensuring a cool working environment even on the warmest production days.
What equipment does the solution include?
The solution includes a Gema automatic paint booth, a two-stage heat recovery system, and a ventilation unit with a cooling function. The oven's waste heat is directed into the central heating system.
Where does the added system's required energy come from?
The added system's energy needs are covered by the oven's waste heat, which was previously wasted.

Compressor waste heat recovery for heating – forecast over 120 MWh per year

Elister installed an automation-controlled heat recovery system in the compressor oil cooling circuit for AQ Lasertool OÜ, directing the residual heat of the 55 kW compressor into the building's heating system and domestic hot water. The system recovers an average of 10 MWh per month, with an annual forecast of over 120 MWh, resulting in significant heating cost savings and reduced CO₂ emissions.

Hot-dip galvanizing exhaust air heat recovery and vacuum compensation

At Galv-Est AS's hot-dip galvanizing plant, the 45,000 m³/h of air extracted above the zinc bath created a strong vacuum and significant loss of thermal energy. We installed a ventilation unit with a plate heat exchanger featuring corrosion-resistant elements, which recovers heat from the galvanizing process and compensates for the vacuum. The solution enables efficient use of heat even at temperatures down to -25°C without additional heating.

Powder Coating Line Heat Recovery System

Elister installed a heat recovery system alongside Sami AS's new powder coating line, which reuses the heat from the hot air exiting the powder oven for heating. The heat is directed to maintaining the temperature of the metal washing bath, to the central heating system, and to the ventilation of the paint and assembly workshop, requiring no additional energy source. The system's projected payback period is approximately **5 years**, likely even shorter due to rising energy costs.
