Modine's HSB24 is a high grade hot water/steam unit heater that can be fitted into a new or already existing hydronic system with ease. The HSB24 can emit 24,000 BTU/hr of heating power with a powerful fan behind it for air propulsion. High grade steel is used for the casing to ensure durability and longevity. Designed for horizontal use, the unit heater is excellent for heating long corridors or blanketing walls with heat. The HSB24 has supply and return connections on the top and bottom of the unit, allowing it to be installed facing any direction.

Product Information:

Top and Bottom Connections
• The HSB24 has top and bottom connections for supply and return piping. These vertical connections allow the unit to be rotated 360 degrees without changing any piping configurations.
Two Piece Casing
• A two piece casing is used with the HSB24, allowing for incredibly easy access to the coil in case maintenance is required.
Mounts Directly To Piping
• The HSB24 mounts directly to the supply and return piping, simplifying installation and eliminating the need for additional mounting accessories. The piping provides all needed support for the unit heater.
Thermal Shock Resistant
• The serpentine copper tube coil is very resistant to thermal shock even at high steam temperatures. This prevents undesired warping of the coil itself, as well as decreasing necessary maintenance.
Smart Coil Layout
• The layout of the coil does not include coil headers. This eliminates potential leaks and maintenance without increasing the overall size of the unit.
Baked-On Polyester Paint
• The HSB24 features a neutral colored baked-on polyester paint, providing excellent corrosion resistance and durability while blending in with a wide variety of environments.
Modine Installation
• Installation by a professional installer is required by the manufacturer.
