## Business Overview

Durodyne is the unified online home of two long-established HVAC industry brands: Duro Dyne Corporation and Supco (Sealed Unit Parts Co., Inc.). Together, these brands offer a comprehensive catalog of products for HVAC technicians, sheet metal fabricators, refrigeration service professionals, and appliance repair technicians. The company is headquartered at 81 Spence St, Bay Shore, NY 11706, with additional manufacturing and warehousing facilities in Ohio, Colorado, and Canada.

Duro Dyne, founded in 1952, is recognized as the leading manufacturer of sheet metal accessories and equipment for the HVAC industry. Duro Dyne pioneered innovations including Flexible Duct Connector, Vane Rail, Self-Drilling Screws, and automated Pinspotter machines. Its product line covers duct fabrication, air distribution, zone control, access doors, fire dampers, insulation fasteners, duct connection systems, and suspension hardware.

Supco (Sealed Unit Parts Co., Inc.), founded in 1945, specializes in HVACR and appliance repair parts, test instruments, tools, and chemicals. Supco invented the patented Bullet Line Tap Valve, developed PTC technology for hard start kits, and manufactured the first electronic vacuum gauge. Supco's catalog spans HVAC parts, commercial refrigeration components, test instruments, tools, and appliance parts for kitchen and laundry equipment.

The Durodyne platform brings both brands together, enabling distributors, contractors, and technicians to source a wide range of HVAC products from a single supplier. Durodyne offers online ordering, a distributor resource center, technical support, and dedicated customer service for both brands.
