Modine's HC33 is a high-grade hot water/steam unit heater that can be fitted into a new or already existing hydronic system with ease. The HC33 can emit 33,000 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 HC33 has supply and return connections on the side of the unit, allowing it to be installed into areas with low clearance.

Side Connections

The HC33 comes equipped with side supply and return connections, permitting the unit to be rotated 360° without piping changes. This also allows the unit heater to be installed in very low clearance areas with little effort.

Two-piece Casing

A two-piece casing is used with the HC33, allowing for incredibly easy access to the coil in case maintenance is required.

Tapped Suspension Holes

The HC33 comes with pre-drilled tapped holes for suspension by threaded rod. This reduces installation time for your contractor, saving you money on installation.

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 HC33 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.
