Description

Reznor model WS steam/hot water suspended heaters are design-engineered to be technically advanced and aesthetically 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 attractive.

The heat exchanger is made of one or two rows of coils (standard steel or optional copper tubing) 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.

The standard steel tubing is very strong and long lasting. Steel tubing is designed for hot water applications up to 150 psi. 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 large tube diameter reduces the water pressure drop, which means these units require lower pump pressure than other hydronic heaters.  It also allows a very rapid heat radiation. FOR STEAM HEATING APPLICATIONS, COPPER TUBING IS REQUIRED.

Heat exchangers are subjected to a pressure test at over 350 psi (25 bar) before leaving the factory. The standard 2-speed motor is a hermetically sealed motor which is maintenance free.  The motor is wired for 115/1/60 supply voltage.  The motor speed is field adjustable to run at high or low RPMs. The flexibility of changing motor speeds allows the installer to adjust the unit to high speed for increased BTUH output or low speed for reduced noise level.  All motors have internal protection as a standard feature. All model WS units can be installed for either vertical or horizontal discharge.
