AIR PROBLEMS IN HOT WATER HEATING SYSTEMS - 
TRY A SPIROVENT

Do you have Air Problems ???????
  
TRY A SPIROVENT !
  
A remarkable product that ELIMINATES 100% of the free air, 100% of the entrained air, and 99.6% of the dissolved air from water in chilled and hot water systems.  It is so completely efficient that it starves the water for air causing it to seek out air pockets, draw the pocket of air into solution and then take it back to the SPIOVENT for elimination.
 
A Spirovent, when sized properly for system velocity, actually does what a typical tangential air separator was supposed to do.
  
Do you have an air vent that leaks or spits water? TRY A SPIROTOP !
   
This vent is the vent incorporated into our larger SPIROVENT units.  Solid brass constructions, guaranteed performance and workmanship for 20 YEARS!
  
And Guess What?  It's less expensive than a steel Hoffman # 79 !!!!!
  
                       
    
DOUBLE PROTECTION!
   
A SPIROTRAP is an option which can be internally incorporated into a SPIROVENT or is available as an independent means of dirt separation in hot and chilled water systems.  Want to reduce or eliminate your chemical requirements, install a SPIROTRAP and reduce the scale and sediment in your system down to as low as 5 Microns.
    
How small is 5 Microns?  It's about what's left in the bottom of a cup of hot chocolate!
 
We have a demonstration unit that tells the story.,  Let us show it to you!
