DEKHOTINSKY TRIPLE WALLED DRYING OVENS 



ELECTRICALLY HEATED AND REGULATED 



3583-4 



3583-4 OVEN, drying, triple walled DeKhotinsky. 



Distinctive Features. 



1. A new bimetallic thermo-regulator (patent applied for), which is actuated 

 by a difference in temperature of 1/C. (This does not mean control 

 of temperature throughout the oven chamber to 1/4 C, but within the space 

 adjacent to the regulator.) Charts made with a recording thermometer actually 

 show less than a degree of variation through periods of 24 hours. 



2. Location of the heating elements in the base of the oven beneath the false 

 bottom instead of in the oven chamber where they are shielded by an iron 

 deflector, preventing radiant heat from striking the lower shelf. 



3. An air circulating system which reduces the difference in temperature between 

 the top and bottom shelves to less than a degree C. instead of 12 to 20 

 degrees, as usually found. 



4. The DeKhotinsky standard system of heating, by which extra heating units 

 may be thrown into or out of the circuit to obtain any desired temperature up 

 to the maximum. 



5. Replaceability of heating units by the user from outside the oven in case of 

 burn-out, at a nominal cost, without the necessity of interrupting the drying 

 process or sending to the factory for repairs. 



G. Location of the contact points of the make-and-break outside the oven and 

 their enclosure in a tight case, preventing any possibility of the explosion of 

 inflammable gases generated within the oven. 



7. Ease of adjustment of temperature, by means of the thermo-regulator, from 



room temperature to the maximum temperature of the oven. This is accom- 



plished by turning a removable key outside the oven, actuating a worm gear 



which sets the contact points to open or close at the desired temperature. 



OVENS, drying, triple wall, DeKhotinsky electrically heated and regulated,
