Modine HER50C-SP Horizontal Electric Unit Heater, 5kW, 240V Single Phase

17,100 BTU Commercial Electric Heater | 380 CFM, Ceiling or Wall Mount, Adjustable Louvers

The Modine HER50C-SP delivers 5kW (17,100 BTU) of heat from the same compact cabinet as the smaller HER30. It produces 67% more heating output while sharing identical dimensions (14.25 x 17.5 x 17.25 inches) and weight (34 lbs). For facilities that need more warmth without upsizing equipment, the HER50 is the practical step up in the HER series.

Unlike the HER30, this model supports an optional wall mounting bracket in addition to standard ceiling suspension. This makes it a good fit for spaces where overhead structure is limited or where wall placement provides better airflow coverage. The unit runs on a 240V single-phase circuit with no gas line or venting required.

Key Features

• Wall or ceiling mounting flexibility: Standard ceiling suspension uses two 3/8"-16 tapped holes for threaded rod or pipe hanging. An optional one-point wall bracket allows a 90-degree horizontal swivel to direct airflow where it is needed most. This gives installers more placement options compared to smaller HER models.

• Higher temperature rise in a compact body: At 42°F temperature rise (vs. 25°F on the HER30), the HER50 pushes noticeably warmer air through the same 380 CFM fan. Occupants feel the heat sooner, which matters in garages, workshops, and loading areas that open frequently.

• Adjustable horizontal and vertical louvers: Standard horizontal deflector blades direct air up or down. Optional vertical deflector blades add left-right control for full directional coverage along building perimeters.

• All-electric, zero-combustion operation: No gas connection, no exhaust pipe, no emissions at the point of use. Safe for enclosed spaces like greenhouses, food storage areas, and mechanical rooms where air quality is a concern.

• Hinged bottom panel for easy service: Terminal blocks, contactor, and wiring are all accessible through the swing-down panel without lowering the unit. The fan and motor assembly can also be removed in place.

• Industrial-grade construction: 20-gauge steel casing, cleaned, phosphatized, and finished with baked-on polyester powdercoat. Resists corrosion in humid environments.

Modine HER50C-SP Specifications

Also Available in Other Voltages

All voltage variants share the same physical cabinet, BTU output, airflow, and heat throw. Three-phase options (208V, 240V, and 480V) are available for commercial and industrial electrical systems.

Applications

The Modine HER50 is an electric alternative to gas unit heaters for commercial and light industrial buildings. At 5kW (17,100 BTU), it heats larger zones than the entry-level HER30 while fitting through the same openings and mounting to the same brackets. Typical installations include workshops, garages, loading docks, maintenance rooms, greenhouses, storage buildings, and stairwells.

The optional wall mount bracket makes the HER50 practical for spaces without a strong overhead structure or where wall placement provides better air distribution. Multiple units placed around a building perimeter create overlapping airflow that "wipes" the walls with warm air, reducing heat loss through exterior surfaces.

HER50 vs. HER30 vs. Amp Dawg AMP057A

The HER50 delivers 67% more BTU output than the HER30 in an identical cabinet and adds wall mounting support. It matches the Amp Dawg's temperature rise (42°F) and comes close in total output, while offering adjustable louvers, multi-voltage options, and industrial-grade construction. The Amp Dawg has a longer heat throw (20 ft vs. 12 ft) and a 10-year heat exchanger warranty, but is limited to single-phase 208-240V power.

Available Accessories

• Wall Mounting Bracket: One-point suspension bracket for wall installation. Allows 90-degree horizontal swivel. Available for HER50 through HER250.

• Pipe Hanger Adapter Kit: Two drilled 3/4" IPS pipe caps and two capscrews for threaded-pipe ceiling suspension. One kit per unit.

• Unit-Mounted Thermostat: Field-installed thermostat kit with 40°F to 90°F range. Mounts directly on the HER unit.

• Low-Voltage Control Kit: Enables connection of a low-voltage thermostat. Cannot be combined with the unit-mounted thermostat.

• Summer/Winter Switch: Winter mode cycles the fan and elements together via the thermostat. Summer mode runs the fan continuously for air circulation while the thermostat controls elements only.

• Vertical Deflector Blades: Add left-right airflow control alongside the standard up-down horizontal louvers.

Warranty

The Modine HER50C-SP includes a 2-year parts warranty covering material and workmanship defects. Sheet metal components are covered for 1 year. Warranty applies to the original owner-user and does not cover labor. Full terms are available from Modine Manufacturing Company (Racine, WI).

Frequently Asked Questions

How much space can the HER50 heat?

At 17,100 BTU, the HER50 can heat approximately 400 to 550 sq ft in a well-insulated space with standard ceiling height. Exact coverage depends on insulation quality, ceiling height, climate zone, and target temperature. Use a BTU calculator for precise sizing.

Can I mount this heater on a wall?

Yes. An optional wall mounting bracket is available for the HER50 (and all HER models from HER50 through HER250). The bracket provides one-point suspension with a 90-degree horizontal swivel for flexible air direction. Ceiling suspension hardware is included standard.

What is the difference between the HER50 and HER30?

Both share the same compact cabinet (14.25 x 17.5 x 17.25 in, 34 lbs) and the same 380 CFM fan. The HER50 produces 5kW (17,100 BTU) versus 3kW (10,200 BTU) on the HER30, resulting in a 42°F temperature rise instead of 25°F. The HER50 also supports wall mounting, which the HER30 does not.

Does this heater need a gas line or a vent pipe?

No. The HER50 is fully electric. No gas connection, no exhaust pipe, no combustion byproducts. It connects to a dedicated 240V single-phase circuit and is ready to operate.

Is the HER50 better than the Amp Dawg AMP057A?

They serve different needs. The HER50 is an industrial-grade unit with adjustable louvers, multi-voltage options (including 480V three-phase), and a compact 34 lb cabinet. The Amp Dawg delivers slightly more BTU (19,437 on high), has a longer 20-ft heat throw, and includes a 10-year heat exchanger warranty, but is limited to 208-240V single-phase power and has no adjustable louvers.

What circuit does this heater require?

A dedicated 240V, single-phase, 60 Hz circuit. Power supply must be within 5% of rated voltage. A fused or circuit breaker disconnect switch is required. Have a licensed electrician confirm your wiring and breaker sizing before installation.
