Rittling Induction Units


Benefits
Applications

  • First cost savings. Reduction in the volume of air required as in a conventional air system. Primary air volume is
    based upon ventilation requirements. This greatly reduces the ductwork and the central air handler sizes.
  • Energy savings as the water temperatures for heating and cooling are not as high or low, respectively as in a standard
    heating and cooling system. Perfect for condensing boiler applications used today.
  • Low central station air handling system costs. Installation costs are minimized by reducing the requirements for the
    building service connections for electricity, water and drainage
  • Quiet reliable operation – Each induction unit has a specially designed balancing damper, acoustical plenum insulation
    and high efficiency nozzles and coils. No sound generating equipment in the space such as fans.
  • Lower Maintenance costs – Rittling induction units have no moving parts thus reducing the required maintenance.
    Only the lint screens need to be cleaned occasionally.
  • Gravity heating on vertical units is available. The air distribution system can be shut down to save fan horsepower.
    Hot water circulates to maintain the temperature in unoccupied rooms. Simple, economical convector style heating.
  • Nine (9) models are available in low profile wall hung, vertical wall hung and ceiling mounting types. Each model has
    4 lengths and 5 nozzle arrangements to meet the desired outside air ventilation and heating/cooling capacities for
    the application
  • Rittling induction units are provided in both 2 pipe and 4 pipe systems which provides an almost unlimited range of
    cost and energy saving design options
  • Variety of options are available from electric heat, different coil connections, nozzle styles and drain pan configurations.
  • Custom cabinetry for new and replacement installations – Rittling provides a powder coated durable sheet metal
    cabinet fit to suit the project. Adjustability is built into the cabinet design for variances found in the field. Rittling
    also provides a step by step installation instruction manual for the contractor responsible for installation.

Rittling Induction units are designed to provide air quality and acoustical performance similar to conventional displacement systems but at the same time saving energy. Standard induction principles are used to effectively blend
conditioned outside air with filtered room air to deliver a constant volume (variable temperature) displacement supply
of air to the space while maintaining comfortable space conditions.

These systems have been in use since the late 1950s. The induction unit is an ideal solution for commercial office
building and condominiums.
