Roesler R 620 EC vs R 780 EC: catalog comparison
Within the EC series table, total bowl volume changes from 620 L to 780 L, while processing channel width changes from 430 mm to 430 mm. These values describe the listed bowl and channel, not a permissible workpiece load or size.
Basis: Roesler EN.145.22 revision04/2023, physical page 11, EC series. Current configuration and availability are not verified.
Versioned specification differences
| Catalog field | R 620 EC | R 780 EC | Right minus left |
|---|---|---|---|
| Total bowl volume | 620 L | 780 L | 160 L |
| Processing channel width | 430 mm | 430 mm | 0 mm |
| Listed maximum outer diameter | 1695 mm | 1805 mm | 110 mm |
| Connected load | 7.5 kW | 7.5 kW | 0 kW |
The maximum outer diameter changes by 110 mm (1695 to 1805 mm). Connected load changes by 0 kW (7.5 to 7.5 kW). Read each field independently; a diameter does not establish rectangular installation space and connected load does not predict measured operating consumption.
Compare catalog entries against your own limits
Leave all four fields blank for the catalog comparison. For a limit screen, enter all four positive values in the displayed units. No limit is prefilled. These are catalog screening conditions, not part loading or site-installation limits.
Keep channel dimensions separate from installation dimensions
The maximum outer diameter changes by 110 mm (1695 to 1805 mm). Connected load changes by 0 kW (7.5 to 7.5 kW). Read each field independently; a diameter does not establish rectangular installation space and connected load does not predict measured operating consumption.
Channel width is one listed geometry value. Part geometry, freedom of movement, media access, separation and collision risk need a workpiece-specific review. Obtain the current installation drawing for access, height, guarding, service space, utilities and floor loading; do not square the listed diameter to invent a footprint.
Source and electrical-value basis
The original Roesler rotary-vibrator catalog, EN.145.22 revision04/2023, physical page 11, supplies the EC series facts. Original diagrams summarize those values without reusing OEM photos.
Within the EC series table, total bowl volume changes from 620 L to 780 L, while processing channel width changes from 430 mm to 430 mm. These values describe the listed bowl and channel, not a permissible workpiece load or size.
Connected load is retained in kW exactly as a catalog field. It is not a measured energy consumption, a price estimate or an identified individual motor rating. Confirm the actual electrical connection and operating configuration with the supplier. This independent reference does not establish a Roesler partnership or Jintaijin equivalence.
Questions about this model pair
What differs between R 620 EC and R 780 EC?
Within the EC series table, total bowl volume changes from 620 L to 780 L, while processing channel width changes from 430 mm to 430 mm. These values describe the listed bowl and channel, not a permissible workpiece load or size. The maximum outer diameter changes by 110 mm (1695 to 1805 mm). Connected load changes by 0 kW (7.5 to 7.5 kW). Read each field independently; a diameter does not establish rectangular installation space and connected load does not predict measured operating consumption.
Does total bowl volume predict usable part load?
No. Media filling, parts, process conditions and permissible loads need supplier confirmation and a referenced trial. The volume here is the total bowl volume from the source table.
What does the optional limit screen establish?
It checks whether the listed total volume and channel width meet your entered minima, and the listed maximum diameter and connected load meet your entered maxima. All four fields are required if any is entered. Passing these arithmetic checks is not process, part-fit, electrical or installation approval.
Are these current specifications or Jintaijin equivalents?
The values are Roesler EN.145.22 revision04/2023, physical page 11, for the EC series. Current builds and availability need supplier confirmation. These values do not describe a Jintaijin machine or establish equivalence.
