Side-mounted Heating Unit

Working Principle Specification Application Download Inquire Now

The Side-Mounted Heating Unit from AirTS is an advanced industrial air heating system designed for factories, workshops, and warehouses where sidewall installation is more practical than ceiling-mounted systems. Using high-efficiency heat exchangers and horizontal airflow design, this energy-efficient air heater delivers powerful, even heating across large working areas while saving valuable vertical space.Installed along the side of a building, the unit uses hot water (40–90°C) or steam (below 120°C) to heat circulating air and deliver warm airflow horizontally across the working area.

Available in AirTS-SD-I and AirTS-SD-II models, the system provides up to 9,900 m³/h of circulating airflow, with variable air volume control, wireless operation, and automatic monitoring. Its side-mounted configuration is particularly suitable for facilities where ceiling-mounted equipment may interfere with overhead cranes, lighting, or other building installations.

Why Choose AirTS Side-Mounted Heating Units

Space-Saving Wall Installation

Unlike overhead heaters, the side-mounted design frees up ceiling space for cranes, ducts, or lighting, while efficiently directing warm air horizontally into the work zone.

Powerful Air Distribution

The Side Mounted Air Conditioning Unit uses a high-pressure axial fan to push heated air over long distances. Louvers can be adjusted for precise airflow direction, ensuring consistent temperature and comfort throughout the facility.

Flexible Heat Source Options

Compatible with 40–90°C hot water systems or steam below 120°C, this heating unit integrates seamlessly into existing industrial HVAC systems.

Energy Efficiency and Fast Heat Delivery

The optimized air channel and high-performance coil design ensure maximum heat exchange efficiency, delivering warm air quickly while minimizing energy loss — ideal for energy-saving heating projects in factories and warehouses.

Reliable and Easy to Maintain

Built with anti-corrosion coated panels, low-noise fans, and accessible service doors, the unit ensures long-term stable operation even in dusty or humid environments.

Smart Control and Automation Ready

Optional control modules support temperature sensors, wireless controllers, and variable frequency drives (VFD) for intelligent energy management and automated operation.

Side-mounted Heating Unit Working Principle

When hot water or steam passes the equipment, the efficient heat exchanger in the equipment is used to achieve rapid heating of the air.

The air is subject to pressure boost twice through the silencer sponge and the lower trapezoidal convergence, swirls out from the nozzle through the guide vane and is distributed throughout the space from top to down.

Side-mounted Heating Unit Features

Use an air suction axial fan to efficiently recover heat from the top, reducing roof heat loss and addressing thermal drift issues during winter building heating for energy-saving benefits.

Adjusting wind speed and air outlet angle allows for comfortable heating in the working area without creating a sensation of wind.

Aligning the aluminum foil fins of the air exchanger with the airflow direction successfully resolves condensate water leakage.

Efficient heat exchange enables quick warming of the airflow.

Large: the devices in the space are arranged uniformly with even heat distribution

Space: decrease the temp of roof and surrounding walls,decrease the temp difference with the outside, and reduce heat loss through the top and around

Installation and System Design Considerations

Proper installation is essential for effective heating performance in high-ceiling industrial buildings. Before selecting a side-mounted heating unit, consider:

Building Height and Layout: Evaluate the mounting position, ceiling height, and available wall space.
Air Supply Distance: Match the model's horizontal airflow capability to the required heating coverage.
Heat Source: Confirm the available hot water temperature or steam supply conditions.
Heating Load: Calculate the building's heat demand based on insulation, outdoor design temperature, and operating conditions.
Equipment Clearance: Allow sufficient space for installation, airflow, piping connections, and maintenance.
Control Requirements: Determine whether standalone wireless control or coordinated multi-unit operation is required.

For large or irregularly shaped buildings, multiple units may be needed to achieve the desired temperature distribution.
