Doucette Coaxial Coils are designed for use as Water Cooled Condensers, Water Chillers and in Water Source Heat Pumps. This design is being used by Major OEM's around the world and in the ever-expanding wholesale replacement market. Simplicity of design and installation makes this product ideal in both markets.

3 REASONS TO CHOOSE DOUCETTE COAXIAL COILS

     1. DESIGN Doucette Coaxial Coils are engineered for maximum heat transfer with the incorporation of the most advanced and innovative tubing in the industry. The copper or cupronickel tubing is deeply fluted to enhance heat transfer and minimize fouling and scaling. Because of this efficient tube design, Doucette units may be used as both a condenser and /or evaporator; making them ideal for heat pump applications.

     2. QUALITY Doucette's quality is second to none. Raw materials must meet stringent specification requirements before they are accepted for manufacture. Quality is manually checked at every step of fabrication. Each unit is tested on the water side to 350 psig and on the refrigerant side to 450 psig. All Doucette Coaxial Coils are UL and CSA listed. Quality is the number one obligation to our customers.

     3. DELIVERY Doucette maintains a vast inventory of product at our design and manufacturing facilities in York, Pennsylvania, as well as stocking distributors around the USA and Canada. Because of this committment, shipping is generally the same or next day after we receive the order. This is equally valuable to the Wholesaler and the OEM.

APPLICATIONS AND CAPABILITIES

Doucette Coaxial Coils are designed for R-22, R-12, R-502 and other freon refrigerants. The units are rated at standard ARI conditions; Standard 450-79 using R-22. Condenser applications are rated for various TD's (Temperature Difference), Condensing Temperature (CTp) minus Entering Water Temperature (EWT). Nominal Rating at 3 gpm per 15,000 BTUH ton, based on a 20 degree F TD, 105 degree F condensing, 85 degree F Entering Water Temperature. Water Source Heat Pumps are rated for various Entering Water Temperature (EWT), typically 70 degrees F EWT, with corresponding Suction Temperatures (ETp). Nominal Rating at 2.4 gpm per 12,000 BTUH ton. Water Chiller Applications, typical EWT is 50 degrees at 2.4 gpm per 12,000 BTUH ton. Actual tons will be less than "Nominal Tons" due to the lower EWT.
