SYSTEM OF VENTILATION
The Herman Nelson Corporation are makers of the Univent System of Ventilation, the Her-Nel-Co System o f Ventilation, the Herman Nelson Invisible Radiator, the Herman Nelson hi Jet Heater, and other heating and ventilat
ing equipment.
Engineers, architects and school authorities see in the Her-Nel-Co System of Ventilation the practical solution of a most harassing problem.
In this system an invigorating, healthful atmosphere is created and maintained in the school room—without the expensive expedient of preheating a continuous supply of outdoor air.
It is estimated that the Her-Nel-Co operates at 50% of the fuel costs of systems based on supplying the school room with a fixed quantity of outdoor air—irrespective of outside weather conditions. Naturally this modern system also effects decided savings in boiler costs, radiator costs, and building costs.
School authorities, engineers, and architects interested in securing better ventilation, at a saving in fuel, maintenance and building costs, should write for the book, The Herman Nelson Her-Nel-Co System of Ventilation”.
