We provide field maintenance and support for existing Bulk Tank Cleaning operations, along with operational startup and management for newly constructed facilities. Our areas of expertise include facility layout, systems integration, equipment installation, and wastewater pre-treatment processing options for cleaning of Bulk Transportation Equipment.

Primary products offered are air driven rotary spinners and fluid drive units. Air driven rotary spinners are typically deployed with high pressue/low volume single pass use of water with on demand heating systems i.e. Kelton/Peacock Co. self-contained units. Fluid drive rotary spinners are deployed with vat style recirculated use of water with boiler/steam heat systems utilizing plate coils.

In addition to rotary spinner units, Wilmar-Delta provides many additional wash rack/cleaning facility components and services.

“A focal point of the operation, DFW Tank Cleaning was designed with the capacity to wash in excess of 800 tank trailers and totes each month. Cleaning is done in a 28,000-sq-ft building with eight bays — three for chemical washes and one for foodgrade cleaning. The wash rack was designed by Ben Kelley, OMK Enterprises.”
