ELECTRIC UNIT HEATERS Wide Range of Sizes and Types Horizontal air delivery unit heater type (HER series): 32 models, 8 sizes from 3 kW through 25 kW. Recommended for buildings with low ceilings, they are equipped with horizontal air deflector blades to adjust airflow either up or down. Optional vertical deflector blades are also available to deflect air to the right or left, providing complete directional control over discharge of heated air.

ACCESSORIES - FIELD INSTALLED Thermostats Vertical Unit Air Deflectors (refer to page 7 for more info) The unit-mounted thermostat in Figure 9.1 is provided as a field installed kit for a model HER series only. Temperature range of the dial setting is from 40°F to 90°F. • The cone-jet allows the discharge air stream to be adjusted from a concentrated high velocity jet to a broadened air stream to cover a larger area.
UNIT SELECTION - ALL MODELS To order a Modine electric unit heater, specify: 1. Model Number: HER - Horizontal Electric Unit Heater VE - Vertical Electric Unit Heater PTE - Power-Throw Horizontal Electric Unit Heater TM HEX - Horizontal Explosion Proof Electric Unit Heater 2. Select the full model number from Table 10.1 by locating the model series from Step 1 within Table 10.1 at the intersection of the kW rating and supply voltage required.
SPECIFICATIONS - ALL MODELS A. Standards blended, long-life solution of ethylene-glycol, water, and corrosion inhibitors. The heat exchanger shall have three heavy-duty immersion heating elements brazed into a heavy steel bulkhead. The elements shall consist of high-quality resistance wire embedded in a compacted magnesium oxide refractory and sheathed in metal tubing.
The Modine brand has been the industry standard since Arthur B. Modine invented and patented the first lightweight, suspended hydronic unit heater in 1923. No other manufacturer can provide the combined application Products from Modine are designed to provide indoor air-comfort and ventilation solutions for residential, commercial, institutional and industrial applications.
