Coolant system KNOLL VRF 250/1300 with high-pressure pump

Coolant system KNOLL VRF 250/1300 with high-pressure pump

Year of manufacture 2000

KNOLL KSS cleaning system VRF 250/1300

General information:

 Manufacturer: KNOLL Maschinenbau GmbH

Modell / Typ: VRF 250 / 1300 (Vacuum Rotation Filter)

Year of manufacture: 2000

Plant number: AE 1073 (reference number)

Performance data:

Filter power: max. 250 l/min (with emulsion); approx. 125 l/min (with oil).

Tank volume: approx. 1,300 liters (large-volume container for stable KSS operation).

Filter fineness: dependent on the stainless steel mesh used, typically 30–60 µm (nominal).

Sorter system: Integrated scraper belt conveyor for automatic disposal of solids.

Technical highlights:

  Non-fiber system: high efficiency due to no costs for filter fleece; cleaning is performed via a back-flushable filtration drum.

 Vacuum principle: An effective filter cake is built by the underpressure, which further increases the filtration fineness during operation.

Compact design: Control and pump technology are integrated in/on the housing AE 1073.

Condition & scope of delivery:

 Control: Original KNOLL control cabinet integrated.

Suitability: Ideal for grinding, turning, and milling processes for centralized or decentralized supply of machine tools.

Installed high-pressure pumps:

TG40-55/22 285

TG25-79/22 345

TG25-95/30 590

KIS 25

Important features:

The system is designed as a "modular system" and can often be retrofitted to existing machining centers via universal interfaces thanks to plug-and-play. It is particularly suitable for processes with high chip generation or non-ferrous metal machining.

Dimensions: The standard dimensions for a VRF 250 system are approximately 2200 x 1500 x 1600 mm (L x W x H).

Weight: The own weight is approx. 1,100 kg.

Connection value: total power approx. 4 kW at 400 V.

System overview

The system serves as a decentralized high-pressure station for supplying machine tools with cleaned coolant (KSS). It combines filtration, pressure boosting, and electrical control in a compact housing.
