Modine electric unit heaters provide a wide variety of options in solving comfort-heating
problems. Each is designed for long heat-throw, uniform heat-delivery, and reduced
maintenance. The types offered are:
• Horizontal Delivery Units (Model HER) – Recommended for use in buildings where
ceilings are low and with few obstructions. Units are normally placed around the perimeter of
the building so that the air stream from each heater “wipes” the wall to produce a blanket of
warm air along walls where heat loss is greatest.
• Power-Throw™ High Velocity Horizontal Delivery Units (Model PTE) –
Recommended where there is a requirement for heat throw greater than can be provided
by standard horizontal delivery models. For hard-to-heat areas, such as frequently opened
loading dock doors or large warehouses, Power-Throw™ units are an ideal choice. A single
Power-Throw™ unit can often replace as many as three smaller horizontal delivery units,
reducing equipment, installation, and maintenance costs.
• Vertical Delivery Units (Model VE) – Recommended for areas where ceilings are high or
where obstructions do not permit good horizontal movement of air.
Standard features include:
• Completely factory assembled and wired for specific power supply ordered.
• Finned-tube sheathed nichrome wire heating elements.
• Totally enclosed motor with thermal-overload protection.
• Fans are statically and dynamically balanced.
• A motor heat shield protects the motor from heated air passing through the heater (VE models).
• Fan and motor assemblies are exposed and can be removed without lowering the unit heater.
• The unit casing is treated for protection against corrosion prior to the application of the
attractive gray-green, baked-on polyester powder coat paint finish.
• A variety of deflector-blade options provides an increased degree of control over
air-discharge direction (VE models).
• Horizontal air deflector blades are standard (vertical deflector blades available) (HER and
PTE models).
• Terminal and junction boxes provide easy access to heating-element terminals, an overheat
control switch, and the power supply and control connections.
• An automatic reset overheat control.
