Tunnel Mine Heater

In plateau mountainous areas, due to the high altitude and year-round snow accumulation, the air conveyed by fans to the tunnel is cold air. The construction personnel endure the cold. The cold air at the entrance of the cave is relatively large, and the equipment loss is relatively large. Our company specializes in the development of cold air heaters. For this part of the working environment to improve the research and development products, it has large air volume, long conveying distance, fast heating, intelligent control, environmental protection, and no pollution.
This type of heater is made of non-standard, which is made according to the actual situation, the number of temperature rises, and the amount of gas. The materials are stainless steel, carbon steel, etc.

The LJ-DR air duct heater is heated by an electric heater. It is a new type of heating equipment used in the air heating system. The equipment is composed of a fan, an air duct heater body and a temperature control system. The heating element adopts stainless steel heating tube, 0Cr27Al7MO2 high temperature resistance alloy wire and crystalline magnesium oxide powder, which are formed by compression process to ensure the service life of the electric heating element. The control part adopts high-precision digital display temperature controller, relays, contactors, etc. to form an adjustable temperature measurement and constant temperature system, with functions such as anti-dry burning, over-temperature protection, overload short-circuit protection, etc., to ensure the normal operation of the air duct heater .
