  • Description

    Reznor’s WS/HA12 series suspended hydronic heaters use a technologically advanced system of steam pressure to deliver even, effective heat in commercial and industrial settings.

    A hermetically sealed 2-speed motor* is maintenance-free, wired for 115/1/60 supply voltage and field adjustable to run at high or low RPMs**. The ability to change motor speeds also allows you to adjust the unit to provide an increased BTUH output (at high speed) or to operate more quietly (at low speed), as needed. 

    The heat exchanger is made of a single row of copper tubing coils with aluminum fins, with approximately 10-½ fins per inch (4 fins per cm). The spacing between the fins makes for easy cleaning and maintenance, an essential feature for keeping the unit heater efficient. The copper tubing, a special requirement for steam heating applications, is extra thick (0.03”, 0.75mm), ensuring long-lasting durability. The large tube diameter also allows for rapid heat radiation and reduces water pressure drop, which means that these units require a lower pump pressure than other hydronic heaters. 

    For added strength and longevity, the heat exchanger is coated in a special paint to better protect the coil over time, as well as increase the unit’s thermal efficiency. All heat exchangers are subjected to a pressure test at over 350 psi (25 bar) before leaving the factory, and the durable copper tubing makes this unit suited for use at a high working steam pressure up to 145 psi.

    This unit features a fan/motor assembly made up of three components: the fan, the motor and the fan guard, which also acts as the main support for the fan. The fan guard is galvanized for protection against corrosion, and is mounted onto the main casing with anti-vibration rubber mountings. All WS series heaters can be installed for either vertical or horizontal discharge.
