The Castle Automatic Circulator 



The Summit of Perfection. No Device has ever been Invented for Forced Hot Water Cir- 

 culation which will do what this little machine accomplishes, for Economy in First Cost or in 

 Operation. Requires no Supervision or Manual Manipulation. Prices and Discounts on 

 Automatic Circulator, several sizes, with or without Motors, also Testimonials from Large 

 Greenhouse Establishments, east or west, furnished on Application. 



While the method of pro- 

 ducing a forced circulation 

 of liquids is the same as in 

 the Original Electric Circu- 

 lator, some modifica t i o n s 

 in construction which we 

 consider to be of vital im- 

 portance are made. 



The great improvement 

 of its being equipped with a 

 valve which requires no 

 manual manipulation to 

 change from forced to grav- 

 ity circulation will be at 

 once recognized as extreme- 

 ly valuable. 



We are prepared to estimate and contract for Boilers, Pipe, etc. Our Steel Plate Boilers are specially constructed for us, and 

 have proved to be marvellously economical and efficient.
