The pig - as clean as the pipeline itself.

Safe discharging of pipelines

Use your product to the last drop and finalize your production the way it begins - with a free pipeline. Gain high-quality product from your pipeline and reduce the cleaning effort for economic production. With the pigging technology of AWH you can process your valuable product almost entirely. The pig shoves the last drop for processing out of the pipeline. You gain an enormous saving potential for the subsequent cleaning process. You save product and reduce the cleaning effort significantly. Merely a thin residue film is left in the pipeline and the pipe's surface is accessible for short and effective CIP cleaning.

Good reasons for pigging technology

• effective usage of the product
• less cleansing agent
• less water consumption
• rapid cleaning results
• short-term amortization of investments

Product recovery / pipe drainage

The pig can be applied there, where:

• pumpable products are conveyed
• frequent or short-term product switch is required
• product blending of two successive phases should be avoided
• a product has very poor fl owing characteristics
• the product value does not allow any waste
• regular cleaning is performedThe water contamination should be reduced to a minimum

Process control

AWH's product recovery systems are a well-proven solution for eliminating the product as well as for gentle filling of process pipework systems for sensitive products and products liable to foam.

Application in product fields

• raw product reception to storage tank warehouses
• preparation phase vessels to mixers
• mixers to storage tanks
• tank farms to filling machines

Typical product examples

• lotion, creams and shampoo
• pharmaceutical liquids
• laundry detergents and cleansing agents
• yoghurt, cheese and curd
• concentrated fruit and syrup

Angle type strainers

AWH strainers are intended for use in pipelines, for coarse cleaning and filtration of liquid flows for the food, chemical and pharmaceutical industry as well as for low-germ processes. They are suitable for use in processing low-viscosity flowing media like water, steam, liquid foods and drinks with high hygienic requirements.

Dirt trap

AWH dirt traps protect the product and the process system, pumps and heat exchangers against damage from foreign bodies. Our dirt traps are Y-shaped (Y filter). The direction of flow is always from the inside to the outside. The trap should be installed so that the filter insert is removed from below. Its streamlined shape ensures reliable processes in a simple and cost-effective way. We offer gap filters with gap widths of 1 mm, 0.5 mm and 0.25 mm. Compared to conventional perforated sheets, slotted tubes offer much greater flexibility and a far larger free strainer surface.

Inline sight glasses

A shock-proof glass cylinder is fitted between two flanges with a seal, and held by stud bolts. The stud bolts have a stop, which ensures a defined pre-tension between the seal and the glass cylinder. Plastic safety screens fulfil the requirement for optimal vision and protection against glass splinters. Alternatively, the proven metal screen can be used as splinter protection.

Sight glasses

A tempered glass pane is screwed to a male part with a welded end using two seals and a grooved nut. The glass is made of borosilicate, which offers excellent strength and thermal stability.

Sight glass fittings

The AWH sight glass fitting - DIN – SS is intended for installation in pipelines. It was designed and built for visual control of the flow of fluid in the food, chemical and pharmaceutical industries and for low-germ processes. Suitable flow media include water, steam, food, liquids from the chemical and pharmaceutical industry subject to a hygienic standard.

Sight glasses with wipers

Sight glasses with wipers are used for liquids with high solid content, which tend to form deposits. A manually rotated wiper reliably removes the deposits from the inside of the glass.

Lights for sight glasses

The light for the sight glass comes in two different versions:

• 1. for the DIN-SS sight glass which lights through the medium and
• 2. for the DIN welding sight glass which illuminates the medium.

The lights are suitable for illuminating sealed vessels like boilers, tanks, bunkers, silos and agitators and for visual flow control in pipelines.

When properly installed, a protective rating of IP65 in compliance with EN 60 529 / DIN VDE 0470 Part 1 (dust-tight and water-jet proof).

Butterfly valves

Butterfly valves have been a key system component in the hygiene industry for decades. They were developed, designed and manufactured for installation in pipelines for shutting off a flow of liquid. Suitable flow media include water, steam, petroleum, food, liquids in the chemical and pharmaceutical industry and pasty media.

AWH butterfly valves represent maximum quality, reliability and hygiene. The butterfly valves are supplemented with a comprehensive range of accessories, and therefore offer the ideal solution for every application. In addition to a range of manual operations, the valves can easily be equipped with pneumatic or electric drives. A wide range of initiators and control heads are available to monitor performance. A clear advantage of AWH butterfly valves are the bearing bushes which minimise the wear on the axle, making our valves very durable. Of course, we also provide you with all standard approvals and test certificates for the materials used, such as EHEDG, ATEX, APZ 3.1. to DIN EN 10204, FDA and EC regulation 1935/2004.

VPureMix^® – Magnetic Mixing Technology for Processes that run smoothly

The AWH VPureMix^® magnetically driven mixer is designed for applications with the most stringent demands in terms of safety and sterility. A magnetic coupling eliminates the risks associated with conventional shaft grommets, such as leaks and contamination. All the functions are monitored continuously by a sensor, and can be read off and documented directly by a monitoring unit.

The VPureMix^® guarantees maximum mixing power and product reliability down to the last drop. The magnetic actuator almost completely eliminates all shear forces and allows full tank drainage during ongoing operation. The mixer head has ceramic bearings, and is characterized by low shear forces and its ability to run dry with zero problems. This means no product residue, gentle mixing even with small quantities of product, and no risk when draining the tank during a mixing operation. The open design of the mixer head makes for any easy cleaning procedure that uses a minimum of water, produces much less wastewater and requires very little time.
