High-Speed Performance

Each U-series machine delivers industry-grade filling speeds powered by gravity-fed systems. Rates depend on the container size:

Containers Per Hour

Model

4 Liter (1 Gallon) 10 Liter (2.5 Gallon) 20 Liter (5 Gallon)
U2 720 440 240
U3 1080  660 360
U4 NR* 880 480
U5 NR* NR* 600
U6 NR* NR* 720

*NR is not recommended for sustained filling but only for short runs. For short runs, all filling nozzles need not be used.

**Pneumatically operated machines have slightly higher production rates.


Precision and Accuracy

Crandall's U2-U6 models are designed to deliver accuracy within ±0.5% of the target gross weight when properly installed. Consider our Dribble Flow Shut-Off option for applications requiring greater precision, which slows flow near the end of each fill.


Key Benefits

  • Non-electric Operation: Minimal risk in explosive environments.
  • Simple Maintenance: Welded steel construction for durability, requiring no specialized skills for repairs.
  • Flexible Product Changes: Easy-to-clean valves with simple disassembly. Pneumatic heads require just 10 bolts to remove.
  • Container Versatility: Adjust weight settings and nozzle height for quick container changes.
  • Safety-first Design: No large moving parts, minimizing injury risks. Optional explosion-proof motors for motorized conveyors.

Installation and Operation

Easy Installation

No special foundation is needed. Units are pre-assembled and ready for quick setup by plant personnel.

Seamless Operation:

  1. Place empty containers on the platform.
  2. Start the fill on each nozzle.
  3. Once the target weight is reached, the nozzle automatically shuts off.
  4. Move the filled container to the discharge conveyor.

Use fewer nozzles during short production runs.


Air and Electrical Requirements

  • Mechanical Models: No air requirements.
  • Pneumatic Models: 5 liters/min at 5.6 kg/sq cm (0.2 cu ft/min at 80 PSI) per nozzle.
  • Optional Motorized Conveyor: It is equipped with 1/3 or 1/4 HP motors (depending on availability) and requires up to 5.5 amps.

Optional Features

  • Motorized Discharge Conveyor: Quickly moves filled containers off the platform.
  • Sanitary Piping & Valves: 3A stainless steel for food-grade applications with easy cleaning clamps.
  • Rollers on Platforms: Facilitates handling of larger containers.
  • Fume Covers: Essential when filling volatile products; connects to your vacuum system to remove fumes.
  • Casters: Enables easy machine relocation.
  • Holding Tank: Maintains consistent product flow when pressure varies.

Space and Weight Requirements

Model Floor Space (cm) Floor Space (in) Shipping Weight
U2 112 x 82 cm 44 x 32 in 425 kg (940 lbs)
U3 146 x 82 cm 58 x 32 in 610 kg (1345 lbs)
U4 180 x 82 cm 71 x 32 in 714 kg (1575 lbs)
U5 215 x 82 cm 85 x 32 in 837 kg (1845 lbs)
U6 249 x 82 cm 98 x 32 in 989 kg (2180 lbs)

Pro Tip: Consider using casters for easier movement when space is limited.


Low Noise Operation

Pneumatic models feature exhaust ports with mufflers to keep noise levels below 20 dB, ensuring a quieter working environment.


Applications
