◆ Food Drying ◆
Drying food, agricultural produce and seafood requires controlled moisture removal while preserving product quality. The ZERO BOILER food drying system uses a heat pump for continuous drying at relatively low temperatures, recovering heat from the circulating air for reuse. It can be configured for fruit, vegetables, chili peppers, sweet potatoes, potatoes, mushrooms and seafood. Drying temperature and time are adjusted to suit each product. Combined with trolley-loaded drying rooms, the system can be scaled from small farm applications to large food processing facilities. A closed-loop or recirculating configuration can help reduce heat, odor and dust released outdoors. Recover and reuse drying heat while supporting consistent product quality.
◆ Heating Mode ◆
		Heats the drying room at the start of operation. Raises the temperature to the setpoint. Allows product-specific temperature and time settings. Can be engineered for large drying rooms, including approximately 660–990 m², subject to product load and drying requirements.
◆ Drying Mode ◆
		Combines heating, dehumidification and heat recovery. Condenses moisture from the circulating air and drains it away. Reuses recovered heat to reheat the air. Controls temperature, humidity and drying time.

Precision Drying — Reuse the Heat, Remove the Moisture Conventional exhaust-air dryers discharge warm, moisture-laden air and heat incoming replacement air. Heat is lost throughout the drying process. ZERO BOILER recovers heat for reuse. Circulating air is cooled to condense and remove moisture, then reheated using recovered heat before returning to the drying room. Reusing this heat reduces the energy required for additional heating. Energy Savings, Effective Moisture Removal and Product-Specific Control Reuse heat to reduce energy consumption Heat recovered during moisture removal is used for reheating, reducing heat losses. Support drying through heating and dehumidification Continuously removing moisture from the circulating air helps maintain effective drying conditions. Control temperature, humidity and time Operating conditions are adjusted for each product and drying stage to help limit overheating and excessive drying while supporting consistent quality. Scale from small units to large drying rooms The system can be configured according to product characteristics, processing volume and required drying time. Recover the drying heat you have been releasing—and put it to work again.
◆ Industrial Drying ◆
Industrial drying requires substantial energy to remove moisture from products. Many conventional dryers discharge heated air outdoors, losing heat during operation. ZERO BOILER uses heat recovery heat pump drying to circulate air, remove moisture and reuse recovered heat within the drying process. Controlling drying room temperature and humidity while supplying the additional heat required can reduce energy consumption. The system can be configured for products requiring low- or medium-temperature drying. Recover drying heat and use it repeatedly.
◆ Integrated Industrial Energy Systems ◆
Industrial ZERO BOILER systems are configured to suit facility size and process requirements. Applications include : Drying agricultural produce and seafood in food processing facilities Recovering heat from hot process wastewater Producing hot water for washing processes Reusing heat removed during process cooling Maintaining curing and drying room temperatures Integrating facility cooling with process heat supply Supplying industrial hot water and space heating System planning begins with an assessment of waste heat temperature, flow and availability, together with the required heating load and supply temperature. Heat exchangers, heat pumps and thermal storage tanks are then combined to suit the site. Large facilities can use multiple standard heat pumps in parallel to respond to changing process loads. Design the system around the facility’s energy flows and process requirements.
◆ Waste Heat Recovery ◆
Industrial processes release heat through hot wastewater, cooling water, exhaust air, condensation and other process streams. ZERO BOILER recovers suitable waste heat through heat exchangers and heat pumps for reuse in hot water supply, space heating, drying and process heating. Where a higher supply temperature is required, the heat pump raises the recovered heat to the required level. For the same required supply temperature, a warmer heat source generally reduces the temperature lift required from the heat pump, supporting more efficient operation. Turn waste heat into a useful industrial energy source.
