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.

FAQ

Frequently asked questions

What is the payback period of this heat recovery system?
The predicted payback period is about 5 years. Due to rising energy costs, it is likely even shorter.
How does the system reuse the curing oven's heat?
The hot air leaving the oven is directed back into the process in several stages: first to maintain the temperature of the metal wash bath, then to the central heating system and to heat the workshop ventilation unit.
Does the workshop ventilation require additional energy?
No, the entire painting and assembly workshop ventilation system gets fresh air without an external energy source, using the curing oven's energy.
What additional uses does the system enable?
The system is ready to direct surplus heat energy to heat domestic water and to utilize the compressors' surplus energy in compressed air production.
What results did this solution bring to the client?
The solution significantly reduced energy usage and lowered energy bills, ensured fresh air without an external energy source, and helped realize the client's green thinking vision.

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.

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.
