Industrial laundry heat recovery systems
Industrial laundry heat recovery systems can capture thermal energy from dryer exhaust that would otherwise leave the facility.
Tumble dryer heat recovery and lint laden exhaust
Laundries often have recurring heating demands for wash water, makeup air, process air, or boiler feedwater. When source and demand schedules align, recovered heat may reduce purchased fuel and strengthen facility economics.
Lint, moisture, temperature variation, and production schedules can make tumble dryer heat recovery challenging for equipment with dense fins or plates. Accumulation can restrict airflow and reduce performance. Lepido® uses open Particle Repellent Geometry designed to encourage lint and particles to pass through while maintaining pressure drop level.
Productive uses for recovered energy
A ThermStar configuration can move source energy through a closed loop to approved air or fluid demands. The exhaust remains isolated from the receiving medium.
The most valuable use depends on temperatures, flow, operating overlap, utility rates, existing equipment, and the amount of energy the facility can consistently accept.
Waste heat recovery solutions across industries
Wherever hot exhaust and a useful thermal demand exist, there may be an opportunity to recover and reuse that energy. ThermStar™ applies the same assessment process across industries to identify the strongest opportunities. From a single exhaust source to a multi-facility network, the system can be configured around the application.
Industrial Laundry
Recover heat from lint laden dryer exhaust and cut natural gas costs. Built for the conditions that make conventional laundry heat recovery fail.
Food Manufacturing
Recover energy from oven, cooking and process exhaust in food manufacturing, including humid and particulate laden streams that foul conventional units.
Pet Food Manufacturing
Extrusion, drying and rendering exhaust carries recoverable energy along with moisture and particulate. See how ThermStar handles these conditions.
Foundries
Recover useful thermal energy from furnace and process exhaust in foundry operations, in conditions where conventional recovery is hard to maintain.
Manufacturing
Turn exhausted thermal energy into lower operating costs and reduced emissions across manufacturing operations and multiple facility networks.
Restaurants & Commercial Kitchens
Grease laden kitchen exhaust carries energy worth recovering. The technology behind ThermStar was developed for exactly these conditions.
Operational value
Industrial laundry energy efficiency matters to plant operations, finance, maintenance, and sustainability. A well matched project can lower the energy required for recurring thermal loads. A strategy to reduce natural gas costs should still account for installed scope, maintenance, controls, available incentives, and measured operation rather than relying on a simple equipment rating.
Hotels and linen operations
Hotel laundry energy savings may be available where dryer exhaust and hot water demand occur at useful times. Larger linen, uniform, health care, hospitality, and institutional facilities may have additional loads or several exhaust sources. ThermStar can screen one location or help an operator compare opportunities across a portfolio.
Start with facility data
Provide a brief description of the dryers, exhaust, hours, fuel, and possible heat demand. ThermStar can identify the information needed for a technical review and determine whether the application warrants a preliminary assessment.
What makes an industrial laundry heat recovery project viable
The strongest candidates have a consistent thermal source, a productive receiving load, useful temperature alignment, overlapping operating hours, workable integration, and enough displaced energy value to support the project. A high exhaust temperature by itself is not sufficient.
What can recovered dryer exhaust heat be used for
Possible uses include approved process air, makeup air, process water, domestic hot water, boiler feedwater, and other thermal demands. The selected use must be compatible with the available temperature, capacity, schedule, location, controls, and facility requirements.
Can several laundry facilities be evaluated together
Yes. An organization can begin with a portfolio screen using consistent information from multiple sites. ThermStar can help identify which locations deserve deeper review. Findings from one project may inform later work, but each facility still requires confirmation.
How are natural gas savings confirmed in a laundry
Savings are based on useful recovered energy and the energy it displaces. A project specific method may use temperature, fluid flow, operating time, equipment status, baseline efficiency, and approved conversion factors. Actual reporting depends on the installed monitoring and any utility or internal requirements.
