Low Cost Heating with Hot Water

The Hot Water Type Mine Air Heater uses high-temperature hot water as its heat source. It belongs to the same product series as the steam type unit. This model is also designed with explosion-proof safety considerations.

The system requires very little electricity during operation. The only requirement is a stable supply of hot water from the mine's existing system. We recommend this model for mines equipped with boiler waste heat recovery systems or geothermal energy sources.

The Hot Water Type Mine Air Heater helps significantly reduce electricity consumption and overall heating costs.

Clear Heat Medium Parameters

The heat medium used in this system is 110°C/70°C high-temperature hot water. The working pressure of the heater is 1.0 MPa.
The unit is designed to handle inlet air temperatures as low as -23.3°C. For extreme environments down to -40°C, a customized design solution is available. The outlet air temperature can reach above 40°C.
The system operates reliably in environments with up to 95% humidity and at altitudes below 2000 meters.
Finned-tube heat exchangers are used to ensure high heat transfer efficiency and stable thermal performance.

Key Advantages and Structure

This unit shares a similar structural design with the steam-type heater. It consists of an air heater body, axial fan, casing, and control cabinet. The primary difference is the heat source system.
If your mine already has an existing hot water pipeline system, using the Hot Water Type Mine Air Heater can significantly reduce investment in electric heating equipment and operating costs.

The finned-tube heat exchanger offers low maintenance requirements and a long service life.
For the control system, two options are available:

Fully automatic VFD control system
Manual control system

You may select the appropriate configuration based on actual operational needs.

We have been manufacturing heating equipment since 1996 and have served more than 300 mining enterprises. We have extensive experience in hot water heating system integration and can also provide full-system engineering support.
