EWI - Disposable isolator

Disposable technology

OEB Level 5

Description

Safe and contamination-free dosing, sampling, decanting and weighing of small quantities of highly active or highly hazardous substances are just a small selection of customer-specific operations that can be realised with the disposable isolator (EWI) from HECHT. The EWI is a completely enclosed film system that can be operated using gloves. It protects people and/or products by using a flexible film and various customised connection adapters for a wide variety of containers (drums, bags or cartons, etc.). There is no need for time-consuming cleaning and cleaning validation. Depending on the application, the number of ports for infeed and outfeed as well as the gloves for operation or connections to dryers, mixers, granulators, etc. are individually determined according to customer-specific requirements. are determined individually according to customer-specific requirements.

A special option of the EWI is its patent-pending weighing system. The active weighing technology is located outside the isolator and is therefore not contaminated. Only a weighing pan is located inside. A wide variety of bulk materials can be weighed to an accuracy of 2g.

Technology

System consists of a fixed and a flexible part
Fixed part: stainless steel frame with work surface, suction and holder for disposable foil isolator
Control system adaptable to customer-specific OEL requirements: from simple ventilation to negative pressure operation with or without inertisation
EWI enables various processes, various port designs for customised manipulations (e.g. magnetic stirrers, weighing systems, power/air supply)
The number and type of inputs/outputs and gloves are variable depending on the process requirements
Flexible part: disposable foil insulator (PE, PU, also conductive) is quickly hooked into the frame
Different versions of the disposable foil isolator possible, all parts in contact with the product fulfil pharmaceutical and food-relevant requirements
Product handling takes place via gloves in the disposable film isolator
Disposable film isolator is hooked in, connections connected, pneumatic roll-out seals or vacuum plate fix it in place
Packs are inserted or connected to the connection port, outer liner is fixed to the connection port
Material is removed and processed via gloves, the container and isolator remain closed
After processing, containers are removed after double setting and separation of the film, both remain closed
Disposable film insulator can be quickly replaced and disposed of, no cleaning/decontamination required
EWI is suitable for handling bulk goods from small containers with one or two liners
Station is flexible, transportable (optionally on castors), requires only electricity (230V) and compressed air (6 bar)
