A: If you are using the HBD for ice cream or products that need to be held between -15F – +10F then you will want to get the HL model, If you are using it for products that require a temperature range from -5 F to +40 F then you will want to get the HB model. Keep in mind that if you still want the 3-gallon tub holders they are sold separately, 1 basket for each 2 hole. (For example: If you want an 8-facing unit, then you will want 4 baskets) Part number – BK00-00062
