General Information
Electric coils are an available accessory for use with Price underfloor booster and constant volume fan powered terminal units. The electric coils have been specifically designed to suit Price fan powered terminal units. Electric coils are factory mounted at the discharge outlet of the terminal unit.
Convenient top access door and speed control is provided specifically for underfloor applications. Controls for the electric heat are interlocked and sequenced with the fan in the terminal unit. The electric heat can be energized only after the fan is operating.

Benefits of Electric Coils vs Hot Water Coils Electric coils offer an alternative to hot water reheat coils as an optional accessory for fan powered terminal units. Their benefits are:
  • No need for water lines. Benefits of this include reduced installation costs and elimination of potential leaks which can damage property.
  • Advantage can be taken of the electrical power supply hookup for the basic fan powered terminal unit when making the electrical connection for the electric coil. (Note: the electrical power supply conductor size increases when electrical coil load is added, refer to NEC codes for conductor sizing).
  • No pressure drop across the coils, therefore reduced central fan HP requirements for constant volume fan powered terminal unit applications.
Features / Benefits of Price Electric Coils

Day/Night
  • Heavy gauge zinc-coated steel electrical cabinet and frame..
  • Large electrical cabinet door hinged for easy access and designed for secure closure.
  • Electric coil controls and fan powered terminal unit controls are on the same side of the unit, reducing design restrictions and providing ease of servicing.
  • Electric coil configuration and air flow is matched to eliminate hot spots, providing efficient heat transfer and maintaining element life.
  • Automatic reset thermal cutout is specifically matched to each unit to protect from overheating in case the minimum air flow requirements are not met.
  • Secondary thermal cutout is in the power circuit and is used as a backup in case of failure of the automatic reset thermal cutout.
  • Fan is interlocked with the heating elements to ensure that the fan is operational prior to the heating elements being energized.
  • High grade nickel chrome heating elements provide superior element life and corrosion resistance.
  • A single point connection is provided for heater and fan motor (except 600v/3Ø heater comes with 115v/1Ø motor).
  • Electric coil units are ETL listed to meet electrical safety standards and comply with dual designation CSA 236/UL 1995.
 
Available Options
  • Interlocking main disconnect which is used to de-energize the electric reheat unit once the electrical enclosure door has been opened.
  • Mercury contactors recommended for use in applications sensitive to noise. Mercury contactors provide quiet operating characteristics. Recommended for applications which have frequent demand and cycle repeatedly.
  • Disconnecting contactors for applications where it is necessary to disconnect all three phase power-up.
  • Up to two additional stages of electric heat available to allow for staged heating capacity.
  • SCR (silicone controlled rectifier) option provides infinite heater control using a proportional signal. Element life is extended and noise from contactors is eliminated. This option may be specified compatible with pneumatic, electronic, or DDC controls. See page I-131 for description (UL & CSA certified).
  • Primary or secondary fusing for added safety or to meet local electrical codes.
