Walker Engineered Products

Storage Tanks:

• Dependable and economical. Available in refrigerated cold-wall models and non-refrigerated designs for the dairy, beverage and food industries.

• Built to specific customer design requirements to fit directly into a process line. For bulk ingredients for processing, such as food product with vinegar, oil with cosmetics, concentrates for juice.

• Insulated tanks for dairy, food ingredients, food processing, beverages, concentrates, syrups and a multitude of other applications.

• Walker Engineered Products has a variety of agitation options to suit the individual dairy silo and storage tank application.

We take a flexible approach to storage tank design. Walker storage tanks are formed and can be easily customized to individual application specifications. A tank design can either be all customer driven or Walker engineers assist with tank design, site layout and tank placement, and recommend storage tank arrangements and options. It is this versatility along with the efficiency of our consulting, engineering, manufacturing, installation services, and after sales support that save our customers space, time and cost.
 

Walker tanks meet or exceed 3A sanitary standards or USDA standards so they are the right choice for dairy products, food product ingredients, beverages, high fructose corn syrup, sugar sucrose and water.

Unique design elements of Walker Engineered Products silo style storage tanks:
 

• `Z` rail – ultimate support for storage tank bottoms
  Walker vertical storage tank bottoms sit uniformly flat and level, every time. Bottoms are the most important part of the tank design and our exclusive fabrication technique means the tanks are virtually free of distortion while supporting product weight evenly. The ‘Z’ rail support design allows for shimming corrections to be done on the pad site. They are so well constructed, we have never replaced a Walker storage tank bottom.
   
• Bonding element
  We use a bonding element to attach the “Z” rail bottom support to the bottom tank head so the tank can expand and contract while in use; this eliminates stress on spot welds and stud bolts.
   
• Undercoating
  We apply an undercoating on every “Z” rail tank bottom to eliminate potential corrosion points.
   
• Seismic force and wind load calculations
  Walker engineers work up calculations based on the IBC 2006 building code regulations for seismic force and wind load applicable to the site location for the storage tank. All calculations are available to our customers.
   
• Agitators
  Depending on the product application Walker Engineered Products provides agitators for blending and mixing, to keep solids suspended or to enhance the heat transfer surface. We offer various horizontal agitators with a choice of impellers, vertical turbine style agitators for more viscous products, and gate agitators for whey crystallizers. Also known as the Walker mount for horizontal agitators, the angle mount is pitched up and outward to create a swirling effect up the inside of the tank with liquid returning down the middle. Before recommending an agitator, Walker engineers work through product data specifications such as product viscosity to calculate the best agitator choice to suit the application. All calculations are available to our customers.
   
• Cleanability
  3-A Sanitary Standards emphasize cleanability. Walker Engineered Products is way ahead of the competition with our unique horizontal CIP agitator that is simple, sanitary, efficient and USDA accepted for mechanical cleaning for use in 3-A dairy silos and storage tanks. Walker offers conventional spray down CIP including spray disc, spray dish, drop spray ball and cascading cleaners, and upon request spray-up units for silo style storage tanks.
   
• Heat Transfer
  Heat transfer jackets for full flooded or direct expansion ammonia, glycol or water; internal headers reduce cost by reducing need for external piping and connections. Heat transfer surfaces include dimple, channel and half pipe for heating and cooling.
   
• Sump type outlet
  The Walker sump type drop outlet reduces the tendency of tank content to vortex and suck air in which can damage the product and reduce pump efficiency.
   
• Bolt-on design
  Access equipment bolted onto pre-installed support tabs for easy field installation.

• Pharmaceuticals
• Personal Care
• Fine Chemicals

Walker Engineered Products uses leading edge materials and state of the art fabrication to deliver on our customers’ expectations across a broad range of stainless steel tanks for storage, mixing and processing, including agitated vessels, pressure vessels, round horizontals and vertical storage silo tanks holding up to 70,000 gallons.

The agitation technologies, heat transfer solutions and cleaning options Walker provides to customers are designed for the demands of specific vessel content, design and use.

• We manufacture unique vertical and horizontal agitation for silos.
• We fabricate a full line of agitators –turbine, sweep, scraped surface, counter rotating, squirrel cage, finger baffles and more – for processing, mixing, and blending vessels.
• We engineer heat transfer surfaces including dimple, channel and half pipe for heating and cooling of virtually any vessel.
• Various cleaning options – CIP, spray ball– facilitate the cleanability of Walker vessels, reduce energy consumption, and lower water demand in the cleaning cycle.

Walker can meet the specifications of all your specialized applications with custom stainless steel fabrication using higher alloys such as Hastalloy and AL 6XN®.  And if a pressure vessel requires ASME certification, we can provide that along with other codes, including CRN and PED.

Walker designs serviceability into all of our stainless steel vessels to keep basic customer maintenance to a minimum.  For those occasions when a replacement or repair is necessary, we have field specialists who work on location.

Walker Engineered Products is perceived as a quality organization in stainless steel manufacturing, held in high regard for its traditional Midwest values of hard work and reliability.  Our employees are quality driven, always ready to take advantage of new ideas and streamline processes.  And this shows in the pride they take in sharing our engineering know-how, design capabilities and fabrication experience with our customers.
