Which Unit Works Best in What Setting    

BIG DIPPER® W-250-IS 
BIG DIPPER® W-1250-IS 

Thermaco, Inc. offers three types of Automatic Grease & Oils Removal Systems. These include the Point Source Grease Removal IS (Internal Strainer) system, the Central Grease Removal IS system and the Multiple Source AST (Automatic Solids Transfer) system. What’s the difference between these types and which one works best in what setting?

Point Source Units:            

Internal Strainer IS Series

                          W-150-IS

                          W-200-IS

                           W-250-IS

                           W-350-IS

                           W-500-IS 

The Point Source Grease Removal BIG DIPPER® Internal Strainer (IS) series units utilize an internal strainer basket to capture incidental solids in kitchen wastewater flows. It has a skimming wheel mechanism inside the unit that skims the grease & oils out of the retention area when activated by an integral timer. The strainer basket should be emptied at least once per day, more often if the kitchen is a particularly busy one. IS units work well inside fast food-type restaurants or food preparation facilities where grease removal directly at the source is paramount. BIG DIPPER® IS unit sizes handle kitchen flows of 15 to 50 gallons per minute.
   

Central Grease Removal Units:  

 Internal Strainer (IS) Series

                            W-750-IS

                            W-1250-IS

 

 The Central Grease Removal BIG DIPPER® Internal Strainer (IS) series units handle larger flows than Point Source IS units and are designed to treat flows from multiple sources. A larger strainer basket is used to capture incidental solids present in kitchen drainwater that needs to be manually emptied at least once per day. Like the Point Source IS series, a skimming wheel mechanism inside the unit skims the grease & oils out of the retention area when activated by an integral timer. Multiple Source IS models treat kitchen wastewater flows from 75 to 125 gallons per minute. These systems are geared towards higher kitchen flow installations where grease removal from a central location is important but where small loadings of incidental solids are present.
   

Automatic Solids Transfer

                        (AST) Series

                         W-750-AST

                         W-1250-AST

 The Central Grease Removal BIG DIPPER® Automatic Solids Transfer (AST) series units provide full automatic grease removal and solids handling. Incidental solids are strained out of the kitchen wastewater and trapped in the solids chamber. Periodically, a water-driven eductor automatically empties the incidental solids out of the solids chamber. Like the IS series, the AST series has a skimming wheel mechanism inside the unit which skims the grease & oils out of the retention area when activated by an integral timer. AST models treat kitchen wastewater flows from 75 to 125 gallons per minute. These systems are geared towards larger facilities like hospitals, correctional facilities or casinos where grease removal from a central location is important and where heavy loadings of incidental solids are present.
