REZNOR® WS-18/24 Suspended Hydronic Unit Heater, 18000 Btu, 24000 Btu Water BTU, 3/4 in Inlet, 115 V, 1 ph

Reznor® Model WS Steam/Hot Water Suspended Heaters are design-engineered to be technically advanced and esthetically pleasing which makes it the hydronic heater for the 21st century. This smart new concept in commercial heating units will accommodate all architects who are looking for something new and different. The heating range of Model WS is 13,000 to 350,000 BTUH. The air volume ranges from 270 to 4,750 CFM. The heat exchanger is made of one or two rows of steel coils (standard or optional copper coils) with aluminum fins, with approximately 10-1/2 fins per inch (4 fins per cm). The spacing between the fins makes cleaning and maintenance of the heat exchanger easier, which is essential to keep the unit heater efficient. For Hot Water Applications, the standard steel tubing (Option HA11) is very strong and long lasting. The steel tubing is 0.867" (22 mm) in diameter and 0.040" (1 mm) thick with aluminum fins. This creates a sturdy, efficient heat exchanger. Steel tubing is designed for hot water applications up to 150 psi. For Steam Heating Applications, copper tube (Option HA12) is required. The copper tubing used for the heating coil is very thick (0.03", 0.75 mm), making Reznor heating coils extremely sturdy and long lasting. The copper tube diameter is 0.867" (22 mm) O.D. Designed for high working steam pressure up to 145 psi (10 bar), every heat exchanger is subjected to a pressure test at over 350 psi (25 bar) before leaving the factory. Copper heat exchanger systems may also be used for Hot Water applications.
