A1/25 PEX Electronic Scale Filling Machines

Range of Products

The A1 models are available for gravimetric filling of non-foaming liquid and semi-liquid products which do not contain hard solid particles. The product contact parts are available in Brass and Steel (standard), 316 Stainless Steel, 304 Sanitary Stainless Steel, PVC, Teflon Composite, and Titanium to meet various product requirements.

Range of Containers

Models are available for filling any free-standing metal, glass, plastic, or bag in the box containers from a pint to 6 US gallons( 500 ml. to 25 ltr).

Weighing System & Accuracy

The A1 and A2 electronic model fillers use high-quality industrial load cell bases and controllers. Scale accuracy is 1 part in 10,000. Fill accuracy is within 0.1% of the target weight when the machine is installed correctly and operated. The scale indicator is conveniently located on the device for visibility and easy keyboard entry of set point information. Outputs are selectable in kilograms or pounds.

Filling Speed

Speed is governed by the product's viscosity, product line pressure, and container opening size. Approximate speeds, based on the gravity filling of water from a 10ft. gravity head tank into open-top containers, are as follows:

Containers / Hour
Container	500 ml / 1 liter pint / quart	4 liter / 1 Gallon	8 liter / 2 Gallons	20 liter / 5 Gallons
Model:
A1/10 PEX	600	350	240
A1/25 PEX		350	240	120
A2/10 PEX	1200	700	480
A2/25 PEX		700	480	240

Installation

Your plant personnel may quickly install the A1 and A2 electronic fillers. The scale controller can be plugged into a non-surge 110 vac. Receptacle using the cord provided or hard wired by a qualified electrician. The filter, regulator, and lubricator connect to a 3/8" compressed airliner and connect the flexible product supply line to the 1 1/2" npt feed pipe.

Maintenance

The machines are designed for long service. The scale controllers are in NEMA 4X liquid tight enclosure, so wash down is not a problem. Pneumatic systems are of high-quality components that run for thousands of cycles. The sturdy steel or 304 Stainless Steel frames are welded for long service.

Operation

A1/10 PEX and A2/10 PEX: The operator simply enters the net weight shy of the target, allowing the product in motion to be weighed, then, the operator places the container on the fill platform under the fill nozzle and presses the start button. During this cycle, the scale automatically takes the weight of the container. The nozzle descends approx. l/2" into the opening of the container. When the container reaches the shut-off weight, the nozzle closes without drip and rises. The operator pushes the container off the platform (roller conveyor optional A1) and places another container for filling.

A11/25 PEX and A2/25 PEX: The operator enters set-point 1 (dribble flow) weight and set-point 2 (target weight) shy of the target allowing the product in motion to be weighed. Then the operator places the container on the filling platform under the fill nozzle and presses the start button. During this cycle, the scale automatically takes the weight of the container. The nozzle descends approx. 1/2" into the opening of the container. When the container reaches the set-point 1 weight, the product flow decreases to increase accuracy. When the container reaches set-point 2 shut-off weight, the nozzle closes without drip and rises. The operator pushes the container off the platform (roller conveyor optional A1) and places another container for filling.

Supply of Product

The model A1 and A2 electronic fillers may be supplied from any non-surging source with a constant product supply. Pressure range from gravity to 40 p.s.i.g. 92.8 kg../sq.com)

Safety

The machines are equipped with a quick shut-off button for the operator to interrupt the fill. The system is equipped with a spring-loaded Fail Safe to shut off the product if air pressure is lost.

Change of Container

To change the container, simply enter the new cut-off weight on the scale controller and adjust the height of the filling head. If the container opening is a different size, the filling nozzle may be quickly changed.

Requirements

Personnel Required

One operator, no special skills necessary.

Approximate Air Requirements

1.5 cu.ft./min. @ 80 p.s.i. or 12 s.c.f m. @ 80 p.s.i. (40 ltr/min @ 5.6 kg/sq.cm).

Electric Requirements

110/120 volts, 50/60 hz., single phase, grounded, clean. We suggest using a surge protector. The scale controller classification is NEMA 4 X, liquid tight.

Approximate Operating Space:

A1/10 PEX, A1/25 PEX:

Without conveyor: 21" X 36" (53 X 92cm.)
With conveyor: 21" X 50" (53 X 127 cm.)

A2/10 PEX, A2/25 PEX:

42" X 55" (107 X 140cm.)

OPTIONAL FEATURES

Discharge Conveyor:

3ft. gravity discharge conveyor for the A1/ (shown on cover) suggested for sustained use to ease discharge of filled containers.

Contact Parts:

316 Stainless Steel wetted parts with glass/Teflon gaskets and Titanium wetted parts with glass/Teflon gaskets are available for the chemical industries. PVC with Tygon gaskets for high corrosive and UHMD is also available. 304 Sanitary Stainless Steel for the food industry when required.

Frame Work:

304 Stainless Steel

Coatings:

Two parts (Tile Clad tm.) Epoxy Spray coated steel or Steellt tm. Stainless Steel spray-coated steel.

Operator Splash Guard:

To protect the operator from direct spray in an accidental overfill. We suggest that all operators should wear proper eye protection at all times while operating any filling machine.

Printers:

Several printers are available for labels, cards, and tape. Various printers offer features including net, gross, and tare values, batch time, and accumulation information.

Fume Cover:

A PVC or UHMW fume cover is provided with a 3/4" X 10' long flex hose for connection to your plant vacuum system. This removes fumes around the container while filling directly at the opening. Not applicable for open-top five-gallon pails.
