Purifying Equipment (Air and Water) Radi-Ion Corporation PHYSICISTS - MANUFACTURERS - CHEMISTS Pacific Coast Montgomery Brothers 61 Fremont Street San Francisco General Office and Laboratories 54 West Illinois Street Chicago, U. S. A. Canada Darling Brothers, Ltd. 140 Prince Street Montreal RADI-ION w Radi-Ion is recommended for air puri fication, in mechanical ventilation, where the air supply is drawn from the city streets or recirculated for reasons of economy in heating and air conditioning. Radi-Ion is not a chemical and produces no odor. It is an electrical apparatus that subjects air to the combined effects of ultra-violet light and a special electric discharge that is radiant in character. These combined forces act on the oxygen of the air to produce therein, a state of excitation, or activation, that enormously intensifies the chemical activity of oxygen. This excited or activated oxygen im mediately reacts with odoriferous gases, present in the air supply, as well as those produced by the occupants of the building, immediately oxidizing them to stable, nonodoriferous substances. No new chemical form of oxygen is produced. Simply the physical structure and properties of the oxygen molecules are changed, and these changes specifically conduce to a state of high chemical activity. This physical activation of the oxygen differs materially from methods producing so-called chemical or allotropic modifications of oxygen. In the latter case a new chemical form. of oxygen, that possesses an odor of itself, is produced. Radi-Ion activates the ordi nary oxygen of the air. so that it removes odors by immediately oxidizing them, and produces no odor inherent in the apparatus or process. RADI-ION IS DESIGNED FOR VENTILATION ONLY duty deodorizing, such as is required for many industrial exhausts, kitchens, etc. For such purposes special controlled oxidizing equipment will be recommended. Radi-Ion is as nearly an exact duplica tion of the forces resident in Nature that operate to keep the atmosphere pure and invigorating, as is now physically possible to obtain. Nature has been closely., paralleled in Radi-Ion apparatus and it is the oniy apparatus used for ai purification that accomplishes a perfectly natural re sult in a perfectly natural way. RADI-ION SERVICE^ The services of our engineers are at all times available to assist in the detail necessary for the application of Radi-Ion apparatus to existing ventilating systems, or those in process of construction of contemptation. This expert service costs you nothing. Important- technical publica*. tions and informative trade literature on Radi-Ion will be furnished for the asking. MONTGOMERY BROTHERS CON TROLLED OZONE EQUIPMENT For specific problems in industrial and exhaust deodorization Montgomery Brothers, 500 N. Dearborn Street, Chicago, offer a comprehensive service backed by a full line of ozone producing apparatus. This company offer the services of specia lists in the purification of air in cold storage, the prevention of odor absorption by foods and the preventions^ fungi growths. Radi-Ion is the only air purifying appar atus that is designed for just that purpose. It has no other application or function. Radi-Ion is the result of the experience and research of scientists and engineers who have devoted their lives to ventilation. Radi-Ion is intended for general ventila- . tion only. It is not intended for heavy CONTROLLED OZONE WATER PURIFYING EQUIPMENT Montgomery Brothers Water Purifying equipment is widely used for the purifica tion of potable water, industrial purposes and-swimming pools. Special problems in filtration and the removal of unstable mineral constituents are also undertaken. 744 Radi-Ion Corporation Purifying Equipment (Air and Water) cr - /CW The scheme of installation is illustrated at the left of the cut.

Dimension D may be anything down to zero, in which case the duct shown in broken lines must be provided. When D exceeds three feet this duct is not necessary. SPECIFICATIONS 1. GENERAL: The contractor shall provide and install, as indicated on the ventilating plans, RADI-ION air purifying and ionising equipment, as manufactured by the Radi-Ion Corporation, Chicago, Illinois. 2. CAPACITY: Each RADI-ION apparatus shall be of such capacity as to deodorize and purify the quantity of air handled by the ventilating fan which it serves. Here specify fans to be served by Radi-Ion equipment, either by number and capacity, or other means that will serve to identify the fans for the contractor. - 3. CONSTRUCTION: The RADI-ION apparatus shall employ special, evacuated discharge tubes, of transmission glass, excited by high tension electric current. The discharge produced aha.ll not occur between superimposed electrodes. All electric contacts must be boused so as to render acci dental contact with same impossible. The tubes shall be inclosed in a sheet metal housing, hinged glass door being provided for access to tubes. Duct connections of sufficient size shall be provided for connecting the RADI-ION ap paratus with the ducts of. the ventilating system. Special transformers shall be provided for exciting the tube and so housed that accidental contact with live parts is impossible. A rheostat shall be provided for controlling the intensity of the electric field. An indicating instrument shall be provided for indicating the intensity of the electric field. A eonoidal type fan, directly connected to suitable rise motor, shall be provided for drawing air from the ventilating system, passing same over ionizing tubes and returning it to ventilating system. 4. ELECTRIC SERVICE: RADI-ION apparatus shall operate on (here specify characteristics of electric service). N. B. Only single phase can be utilized. 5. INSTALLATION:.the contractor shall provide and in stall ducts connecting the RADI-ION apparatus with the ventilating system. Air must be taken from the ventilating system, downstream with respect to the filters or other air conditioning apparatus, and connect same with inlet of the RADI-ION apparatus. He will further provide connections between the discharge of the RADI-ION apparatus and the ventilating system, for the return of the activated air. The return connection is made preferably immediately upstream with respect to the inlet of the main ventilating fan. Where the tap-off for supplying the RADI-ION apparatus must necessarily be close to the point of return of the activated air, suitable baffles shall be provided to prevent diffusion taking place between the air to and from the RADI-ION apparatus. 6. GUARANTEE: the contractor shall guarantee, through the manufacturer, the equipment to be free from inherent defects of material and workmanship for a period of one year after date of installation. The apparatus is also guaranteed to maintain the ionic content of the atmosphere equivalent to that normally occuring in Nature. It is further guaranteed that the ionizing equipment will main tain the air pure and free from odor, both in the case of recirculated air, or drawing air from the outside in the congested districts of the city. 745
