Description

Product Description

The Shaft Insulation Electric Heating System represents our highest achievement in outdoor mining equipment. Designed to eliminate the need for expensive equipment houses, this unit features a specialized rain, snow, and dust-proof enclosure that can be installed directly on a simple concrete platform. We developed this "plug-and-play" solution to significantly shorten construction cycles-typically, installation can be completed in just 2 working days. This innovation helped customers like Shanxi Luan Group rapidly deploy heating infrastructure during tight renovation windows without the burden of building new structures.

 

From an engineering perspective, this unit utilizes our state-of-the-art fuzzy control logic to maintain the shaft temperature at a constant 2°C, regardless of external fluctuations. The system is equipped with the "Hongye Cloud" remote monitoring interface, allowing management to track energy consumption and equipment health via a mobile APP anytime, anywhere. For procurement professionals, this system offers the best ROI by combining low installation costs with industry-leading 98% electrical efficiency and a maintenance-free lifespan, all while fully complying with strict MA mining safety standards.

Applications

Ideal for mine shafts located in remote or rugged terrain where constructing a heater plant is logistically difficult or too costly. It provides critical anti-freeze protection for coal mine shaft heads and is equally effective for non-coal mines requiring fast, reliable thermal insulation.

 

Quality Assurance

Our systems are MA certified and explosion-proof, following dual GB 3836 and MT/T 661-2011 standards. Each unit undergoes comprehensive factory testing, including 100% full-load performance and safety interlock verification. Our AAA credit status and ISO certifications (9001, 14001, 45001) reflect our commitment to delivering only the highest quality industrial equipment.

 

Packaging & Shipping

To protect the outdoor-grade coating and internal electronic components, each unit is vacuum-sealed and placed in a reinforced plywood case with a shock-absorbing base. We manage the entire logistics chain, supporting EXW, FOB, and DDP terms, ensuring the equipment arrives at your site ready for immediate installation.

 

FAQ

Q: How does "unattended operation" work?

A: The PLC system automatically adjusts heating stages based on temperature sensors. If any parameter deviates, the remote platform sends an alert directly to your phone.

Q: Is it corrosion-resistant?

A: Yes, the enclosure is treated with high-grade industrial anti-corrosion paint, specifically designed for harsh mine atmospheres.

Q: What is the expected lifespan?

A: With regular inspections, these units are designed for a service life exceeding 15 years.
