Mecasys: Air International Thermal
Air International Thermal: Regulated heating


Air International Thermal is a company dedicated to the manufacture of HVAC systems for automobiles.

Air International Thermal's needs

● Development, design and implementation of a device for preheating the propeller of the blower of the air conditioning system of a motor vehicle at the point where the axis of the electric motor is pressed.
● The required temperature of the part regulated by the control system in real time.

Our solution

● Analysis of the specified requirement and design of the solution.

● Creating a 3D design of the device according to the design.

● Development of a special kind of temperature controller.

● Control software design.

● Installation of the equipment with attention to the safety of the operator.

● Installation and testing of the equipment at the site of its future operation.

● Handing over the operation and maintenance manual, certificate and initial inspection.

● Training of operation and maintenance personnel for the proper use of the equipment.
