 Cascade boilers for higher output

Cascade boilers up to 1 MW
Modular system provides backup should a boiler fail

 Boiler Rigs AvailableATAG Boiler Rigs

Cascade boilers on re4ady made framework

 Atag Controls

 Weather Compensation - Optional sensor

Weather compensation minimises fuel use by reading external and internal
temperatures and adjusting heating flow temperature accordingly

Optimisation minimises fuel comsumption by adjusting the time the system
starts and stops to heat by reading external and internal temperatures

 Low Loss Header for larger boilers and cascaded systems - more efficient than...

  ...Conventional headerLow Loss Header

  Low Loss Header - Improved circulation
  Low Loss Header - Less dry cycling
 
  ...Reverse Return header

  Low Loss Header - Improved circulation
  Low Loss Header - Less dry cycling
  Low Loss Header - Boiler temperatures even
  Low Loss Header - Better stratification

 Use of a Low Loss Header results in

High Fuel Efficiency
Better System Design
