Ductless Splits installed on hospital roof. The design engineer documented the refrigerant piping arrangement shown here (prior to insulation) to use for future project specifications/examples of “how they want it done”.
Prefabricated coil connections installed examples.
Our HGG High-Definition Pipe Cutter and Novarc Spool Welding Robot enable Kleeberg to prefabricate more efficiently, translating to quicker turn around times for our customers.

Transair (aluminum) Air compressor piping installed in food grade manufacturing facility.
The customer for this project handed Kleeberg a list of PVC fittings, specialty equipment IOM’s and a P&ID to complete the install. Our foreman worked directly with the owner to understand their needs and provided an install that is now used as a template for their future projects.
