Machining of parts for the HVAC (Heating, Ventilation, and Air Conditioning) sector
In the demanding field of HVAC, where reliability, energy efficiency, and sustainability are essential, we machine and turn high-precision components tailored to manufacturers’ needs.
Examples of our bar-turning projects for the HVAC sector
NRVI monobloc brazed discharge / C15RPb check valve insert (Ø50)
This check valve insert is designed to prevent any backflow of refrigerant fluid towards the compressor.
This 50 mm diameter part is machined from C15RPb steel, a material suitable for precision turning due to its good machinability. A copper plating operation is then applied to enhance its brazing properties and ensure reliable integration into the refrigeration circuit.
Plate body made of 38SMn28 (Ø61)
This plate body serves as a support and structural component within a refrigeration module. It is a machined alloy steel part, produced entirely on a state-of-the-art machining center.
The complete absence of burrs being imperative, a thermal deburring process has been implemented. This is followed by a heat treatment to increase the component’s hardness. Finally, a final polishing operation enhances its appearance to meet the requirements of an HVAC system.
CuZn39Pb3 Piston (Ø15)
This AKV piston provides precise regulation of refrigerant fluid injection into the evaporator.
It controls the fluid flow and ensures perfectly controlled injection. The part is machine turned from CuZn39Pb3 brass, a material naturally suited to this type of application. A plunge grinding operation then ensures the required dimensional accuracy. Finally, laser marking is applied to enable identification and traceability.
Inlet body in X5CrNi18-10 (stainless steel 304) (Ø40)
This inlet body is designed to receive refrigerant fluid at the system inlet point. It is CNC turned from 40 mm diameter bars of 304L stainless steel. The part features a finish directly from machining. Laser marking is then applied on an automated machine to ensure precise and durable component identification.
