Field-installed 511-L (135-gal.) direct-injection system Field-installed 889-L (235-gal.) direct-injection system
As solution tank mixes become more complex, operators need a better way to manage the products they are mixing in helping to reduce the risk of chemical residue. The integrated direct-injection system provides an additional carrying capacity of up to 511 L (135 gal.) on model year 2015 and older R4030/R4038 (serial number 10,999 and lower) machines and up to 889 L (235 gal.) on the model year 2016 and newer R4030/R4038 (serial number 11,001 and higher) and all model year R4045 machines for raw chemicals and allows injection of single, dual, or triple products directly into the boom depending on installed configuration.
|Machine||Carrying capacity||Maximum number of chemicals injected|
|R4030/R4038 model year 2015 and older (SN 10,999 and lower)||511 L (135 gal.)||Two -one high volume, one low volume|
|R4030/R4038 model year 2016 and newer (SN 11,000 and higher)||889 L (235 gal.) ||Three-two high volume, one low volume|
|R4045||889 L (235 gal.)||Three-two high volume, one low volume|
NOTE: Low-volume tanks and pumps must be configured with at least one high-volume tank and pump. High-volume tank and pump can be configured by itself.
Not only can this help provide quicker changeovers and faster cleanouts, it also helps lower the risk of using multiple chemicals. This is accomplished by allowing operators the ability to isolate higher-residual risk chemicals in the injection system while mixing lower-risk chemicals in the solution tank.
Direct injection can help expand the versatility that an operator has throughout the day while adding additional performance and uptime as they manage the product that they are applying.
Model year 2017 direct-injection systems (attachments BKK10302, BKK10303, BKK10304, BKK10305) will have pump rinse functionality added. Pump rinse functionality can also be added to a current direct-injection system by adding a three-way inlet valve to each DI pump. The three-way valve connects on one port to the chemical tank for normal operation (injection) and to the clean water rinse tank on the other port (for daily pump rinse).
This feature allows for rinse water to be pulled from rinse tank, through the pump head, and out of the boom mixing chamber. This yields the following benefits:
- Automatic rinse system, integrated with pump operating modes, cleans chemical out of pump
- Reduce chemical residual buildup in pump
- Improved maintenance process, while enabling product to be stored in direct-injection tanks between operation
