Electric Unit Heaters

What are Dayton electric heaters?
Dayton electric unit heaters are typically used in areas with high ceilings and are able to heat large volume areas without the need for extensive duct systems. Dayton electric heaters have an energy efficient fan coil design to offer a maximum airflow of 3400 cfm and are ideal for continuous or intermittent use in factories, warehouses, stock rooms and service stations. These unit heaters feature an excellent pull through airflow design for even air distribution & cooler element operation and an automatic reset linear thermal protector to disconnect the heater when the normal operating temperature gets exceeded. Dayton electric heaters have totally enclosed motors with die formed, heavy gauge steel housing to withstand harsh industrial environments. They are equipped with aluminium finned, copper clad steel sheath heating element for efficient operation. Choose from a wide variety of these Dayton electric heaters, available in a maximum heating capacity of 85250 BTUh, on Raptor Supplies.

Uses

What are Dayton electric heaters used for?
Dayton electric heaters employ a forced air system to heat the air using a heating element & a fan for providing primary or supplementary heating in large or exposed areas like factories, warehouses and stock rooms.

Working Mechanism

When you turn Dayton electric heaters on, the electrical current produced heats up the nichrome wire components (also known as heating coils) in the unit. The electrical energy is converted into heat as the current passes through the resistor. Dayton electric heaters come with a fan to draw cold air into the heater. The air passes over the heating elements and is pushed out into the room.

Features

  • Dayton electric heaters have heavy gauge, die formed steel housing and are field convertible from one to three phases.
  • They have a heavy duty, totally enclosed motor and aluminium finned, copper clad steel sheath heating element.
  • Dayton electric heaters feature an advanced inlet louvre design that draws cool air across heating elements for more efficient operation.
  • These electric heaters come with an automatic reset linear thermal protector and Venturi outlet with a large, dynamically balanced fan blade.

Compatible Accessories

  • Vertical and horizontal brackets: These brackets are used to attach unit heaters to walls or ceilings without taking up the floor space.
  • Thermostats: They are used to control the temperature of the heater, either digitally or through a mechanical dial.

Standards and Approvals

Dayton electric heaters are manufactured in accordance with UL & CUL standards to ensure environmental health, utmost user safety and efficient performance of the heaters.

Installation

  • Dayton heaters may be positioned in a way so that the access door can be opened, in order to provide access to the wiring and control compartment. Heaters must be mounted far enough from a wall to allow full opening of the access door, if they are mounted with the access door facing a wall (approximately equal to the depth of the heater).
  • Dayton heaters can be mounted for vertical or horizontal discharge by the use of threaded rods.
  • Optional mounting brackets permit horizontal pivoting of the heater.
  • In order to direct heated air in the desired direction, louvres can be positioned. Depending on how the air is discharged horizontally, louvres should direct air upward or downward.

Frequently Asked Questions

What are the safety precautions one must know before using these Dayton electric heaters?

  • As a precaution against possible electric shocks, all wiring must comply with the National and Local Electrical Codes in the United States.
  • Before energising the heater, make sure that the voltage coming from the power supply matches the ratings printed on the nameplate.
  • Dayton electric heaters are hot when in use. To avoid burns, do not let bare skin touch hot surfaces.
  • If you insert or allow a foreign object into a ventilation or exhaust opening, the heater might get damaged or you might receive an electric shock.
  • Don't block air intakes or exhausts in any way. Keep combustible materials away from the heater, like crates, drapes, etc. Don't install heaters behind doors, furniture, towels or boxes.
  • A heater has hot and arcing or sparking parts inside. You should not use it in areas where gasoline / paint / flammable liquids are used or stored, or in areas where volatile gases are present.

What to do in case of electric unit heater failure?

Assuming that the selected unit heater is the correct choice for the desired heating capacity & airflow, the first thing to check is the wiring & status of the fuse. Users should check & clean dirt or dust accumulated on the motor, causing heating of the motor. Motors should also be lubricated regularly for smooth operation.

Does Raptor Supplies offer other variants of electric unit heaters?

Yes, Raptor Supplies offers multiple variants of electric unit heaters, namely electric baseboard heaters, electric fan coil heaters, heating cables and portable electric heaters.
