“Wire harnesses, sub-assembled components and powder coated housings come together in assembly.

Our experienced team members proceed in assembling the units. Once completed, the units are inspected and electrically tested to assure that they meet all specifications”

Gina Rebillet, Quality Control Officer

Sub Assembly

"a unit assembled separately but designed to be incorporated with other units into a larger manufactured product."
With fully a fourth of the 40,000 square foot facility dedicated to assembly, Perrin Manufacturing has the capacity and experience to offer a broad range of sub-assembly services.

AC hose with crimped fittings

HVAC design demands knowledge of a variety of hose applications. PMI works with heater hose and AC Freon hose, preparing them for use in units as well as selling directly to customers as required.

AC hoses are cut then fittings are crimped on using the Hyair Hydraulic Crimping systems. Quality control tests ensure secure, leak-free fittings at precise fitting angles for installation.

Coils with Expansion valves

Heat exchange coils are sold both as service parts and assembled and installed in customer HVAC units. Shown above a coil fitted with an expansion valve.

Wiring a unit

Pictured above, this small "Wrangler" unit is nearing completion. The powder coated housing has been assembled, coil is ready for final placement, fan is in place and final wire connections are made. The Wrangler is a small skid steer loader which PMI designed this heater for.
