In northern winters, extreme cold poses severe challenges to crop storage in greenhouses and grain warehouses. When temperatures drop below 0°C, vegetable leaves are prone to freezing, and moisture in grains easily condenses, directly leading to reduced yields or even total crop failure...
Against this backdrop, the SIAL-Y150A fuel-fired heater has emerged as a benchmark solution in agricultural cold protection. Leveraging its core strengths of efficient heating, intelligent control, and reliable safety, it delivers stable temperature management for northern vegetable production bases, grain storage facilities, and similar applications.
Balancing High-Efficiency Heating with Fuel Economy
The Y150A features a 150kW high-power stainless steel combustion chamber paired with an imported Danfoss oil pump and a four-stage filtration system, achieving a 30% improvement in fuel combustion efficiency. Field data shows that in -15°C conditions, this unit can raise the temperature of a 2000m² greenhouse from -5°C to 5°C within 15 minutes. Equipped with a 100L high-capacity fuel tank, it delivers 7 hours of continuous operation on a single fill—25% more energy-efficient than conventional systems. Its intelligent thermostatic control automatically adjusts power output, pausing heating when ambient temperature reaches the set point to prevent energy waste.
Industrial-Grade Safety Protection System
Addressing the complexities of agricultural environments, the Y150A features dual overheat protection (electronic temperature sensing + mechanical power cutoff) and air pressure protection. It automatically shuts down when the air intake becomes blocked or combustion abnormalities occur. The unit's housing utilizes heat-resistant cold-rolled steel with a ventilated insulation design. Even after 8 hours of continuous operation, the exterior temperature remains below 45°C, eliminating the risk of burns upon contact. Additionally, the shutdown delayed cooling function ensures the fan stops only after the combustion chamber has fully extinguished, preventing residual heat buildup that could create safety hazards.
Environmental Adaptability Optimization
To address northern dust storms, the Y150A incorporates a dust filter interface at the air intake, enabling external filter installation to intercept particulate matter and extend equipment lifespan. Its IPX4 waterproof rating ensures stable operation in environments with up to 90% humidity, preventing circuit failures caused by condensation. Additionally, the unit supports dual-fuel operation with diesel or kerosene, allowing users to switch based on local fuel costs for further operational cost savings.
Case 1: Shouguang Vegetable Base, Shandong
During the winter of 2024, a cooperative in Shouguang deployed Y150A equipment across 10 connected greenhouses. Comparative experiments revealed that greenhouses using Y150A maintained stable nighttime temperatures between 5.2–6.8°C. Tomato frost damage rates dropped from 12% to 1.5%, with average yield per mu increasing by 18%. The cooperative manager stated: “This equipment not only heats up quickly but also consumes 40% less fuel than our previous electric heaters, saving over 50,000 yuan in heating costs per season.”
Case 2: Wuchang Grain Storage Facility, Heilongjiang
During January 2025's extreme cold snap with temperatures plunging to -32°C, a grain storage facility in Wuchang operated the Y150A continuously for 72 hours without failure. The interior temperature remained above 5°C, effectively preventing corn condensation and mold growth. Technical inspections revealed that grain moisture content fluctuation decreased from ±3% to ±0.8% after Y150A implementation, significantly enhancing storage quality.
