Heat Recovery
Oven exhaust recovery, steam optimisation, and process water preheating.
Food-grade heat exchangers engineered for bakeries, dairies, breweries, and food processing — recovering waste heat from ovens, boilers, and process streams. SS 304L construction with 250–3,500 kW capacity and 12–18 month typical payback.
Three Models,
One Solution
Boiler economiser for food and beverage plants — recovers heat from steam boiler flue gases to preheat feedwater, improving boiler efficiency by 4-8% and cutting fuel costs.
Large-capacity plate heat exchanger for pasteurisation, CIP hot water generation, and process-to-process heat recovery in food manufacturing. Hygienic SS 304L construction.
Recovers waste heat from oven exhaust, dryer discharge, and cooking ventilation systems. Preheats make-up air or process air, reducing gas consumption in bakeries and processing lines.

Applications
Select an application to explore heat recovery for your food production facility.
Industrial baking ovens, fryers, and cooking lines discharge exhaust gases at 150–300°C, carrying substantial recoverable thermal energy. Our EnerAir EAA air-to-air heat exchangers recover this heat for preheating combustion air, drying applications, or space heating — reducing gas consumption by 15–25%. SS 304L construction ensures food-safe operation and resistance to the moisture-laden, occasionally acidic exhaust common in food production environments.

Built for
Food & Beverage
Key advantages for food production heat recovery.
Feedwater Preheating
Recovers flue gas heat to preheat boiler feedwater — cutting steam generation costs in dairy and bakery plants by 4-8%.
Condensing Recovery
Extracts latent heat from moisture-rich flue gases common in food production boilers, maximising thermal capture.
CIP-Safe Exterior
Smooth SS 304L shell resists washdown chemicals used in food facility boiler rooms and plant areas.
Compact Retrofit
Fits into existing boiler flue runs without rerouting steam pipework — minimal disruption to production schedules.
Dairy-Grade Seals
EPDM gaskets and food-safe sealants withstand the humid, warm environments typical of dairy and beverage boiler houses.
Rapid Steam ROI
12-month typical payback on steam-intensive bakery and dairy lines where boiler fuel is the largest energy cost.
Integrates With
Food-Grade Systems
Hygienic stainless steel construction meets food safety standards — retrofit into existing process heating and cooling infrastructure.
Food-Safe Heat Recovery
Pays for Itself.
Food and beverage production consumes enormous amounts of thermal energy — pasteurisation, CIP cleaning, cooking, and cooling all require reliable heat transfer. Our shell and tube heat exchangers recover waste heat from these processes for reuse, while full stainless steel construction ensures food-grade hygiene compliance.
Recover waste heat from pasteurisation and cooking for process water preheating — cutting energy bills significantly.
Full SS 304L/316 construction meets hygiene standards — cleanable tube bundles for CIP integration.
Removable end covers enable tube-side cleaning without disconnecting process pipework — minimising downtime.

FAQs
Common questions about heat recovery for food and beverage production.
Yes. SS 304L (sometimes designated 1.4307) is widely used in food and beverage processing equipment. It provides excellent corrosion resistance, is compatible with CIP cleaning chemicals, and meets food contact surface requirements. The low carbon content (L grade) improves weldability and reduces the risk of intergranular corrosion.
Savings depend on your boiler capacity and fuel costs, but typical boiler efficiency improvements of 4–8% from feedwater preheating translate to significant fuel savings. For a food factory spending £200,000/year on gas for steam, expect £8,000–£16,000 annual savings from a ThermStack TSE economiser alone. Additional savings from process water preheating and oven exhaust recovery can double or triple the total benefit.
Our EnerAir EAA air-to-air exchangers are designed for the moisture-laden exhaust common in food production. For greasy exhaust (bakeries, fryers), we recommend upstream grease filtration to protect heat transfer surfaces. We can specify appropriate pre-filtration systems as part of the heat recovery solution.
Our shell and tube heat exchangers can be integrated into CIP circuits. The smooth internal surfaces of SS 304L tubes facilitate effective cleaning. Removable end covers provide access for inspection and manual cleaning when required. We design heat exchanger installations to support CIP flow rates and chemical concentrations used in food industry cleaning protocols.
Yes. We have experience with dairy processing (pasteurisation heat recovery, whey processing), brewery applications (wort cooling, mash water preheating), and soft drink production (CIP water preheating, process temperature control). Contact us with your specific process parameters for a tailored heat recovery proposal.
Maintenance frequency depends on the application and fouling tendency. For clean steam applications, 12-monthly inspection is typical. For process streams with higher fouling potential (dairy, starch-based products), 3–6 monthly inspection and cleaning may be required. Our design facilitates rapid disassembly for cleaning — minimising production downtime.
