About PRECISION COILS

PRECISION COILS is a manufacturer of hydronic duct heating and cooling coils, supplying equipment used in HVAC systems for commercial, industrial, and institutional facilities. The company produces coils designed for integration into air-handling units, ductwork, and other forced-air systems where precise temperature control of the airstream is required. Their product line focuses on finned-tube heat exchangers that operate with hot water or chilled water as the heat-transfer medium. Typical applications include space heating, reheat coils, preheat coils, and cooling coils in ventilation systems. The coils are constructed with copper tubes and aluminum fins, a common combination that balances thermal conductivity with corrosion resistance. Casing materials are typically galvanized steel, and connections are flanged or threaded depending on the model. Available configurations vary by fin length, fin height, number of rows, number of feeds, and flow capacity. The sample products carried by 3G Electric include models with flow capacities ranging from 0.9 gpm to 5.7 gpm, entering water temperatures of 55°F, and leaving water temperatures from 76°F to 112.1°F. Casing dimensions range from 6-1/8 in x 12-3/8 in x 6 in to 20 in x 26 in x 4 in, with fin lengths from 12 in to 24 in and fin heights from 6 in to 18 in. These coils are typically rated for use in hydronic systems operating at standard building pressures and temperatures. PRECISION COILS does not publish a specific IP rating for their standard coils, but the construction is suitable for indoor ducted environments where exposure to moisture is controlled. The coils are not designed for direct outdoor exposure without additional weatherproofing. 3G Electric stocks multiple SKUs of PRECISION COILS hydronic duct coils, providing procurement specialists and plant engineers with a range of sizes and performance specifications to match system design requirements. The coils are available for global shipment, and 3G Electric supports the line with logistics coordination, including export documentation and freight forwarding. For engineers specifying replacement coils or new installations, the key selection parameters are fin dimensions, number of rows, flow capacity, and entering/leaving water temperatures. The manufacturer part numbers (MPNs) such as W1021212N, SP102612N, and W1011824N encode these specifications, allowing direct cross-referencing with OEM or design documents. PRECISION COILS does not publish a formal warranty statement in the product data provided, but standard industry practice for similar coils is a one-year warranty against manufacturing defects. Buyers should verify warranty terms at the time of order. The coils are manufactured in the United States, and 3G Electric sources them directly from the manufacturer or authorized distribution channels.
