MEDICAL VACUUM PLANT

 

Medical Vacuum Plant Catalogue

 

Vacuum generation is an essential component of the supply system for medical gases in any hospital, and a reliable vacuum supply is indispensable in everyday clinical routine. Schönn has an extensive experience in the development and manufacturing of fully automatic vacuum systems, which are used to aspirate fluids and secretions in the OR, on the ICU and on regular treatment wards.

Schönn offers its customers comprehensive planning, project management, installation and service from a single source. We use only proven quality products that confirm to all relevant statutory regulations and standards. Pump Operating System: Medical vacuum systems complying with HTM 02-01 and ISO 7396-1 are provided with at least two standby pumps (e.g. the design flow of a system with three pumps is provided by a single pump). Medical Vacuum systems complying with HTM 2022 are provided with at least one standby pump (e.g. the design flow of a system with two pumps is provided by a single pump). It can be shown that as more pumps are provided, the energy consumed decreases. By using a larger number of small pumps an energy saving can be achieved. We have pre-determined our plant package using the optimum arrangement of pumps, between 3, so you don’t need to worry about anything other than the flow capacity and footprint.

 
 

UNDEVIATING RELIABILITY

The combination of high-quality components and intelligent system design ensures reliable operation and guarantees the vacuum supply even in the case of component malfunctions. All key components, such as pumps, filters and contactors, are backed up with identical reserve units in a redundant design based on relevant standards and through risk assessment. Built-in safety features can counter critical incidents, such as short circuits, overloads or cable breaks. This redundancy also allows maintenance of the system without interrupting the vacuum supply. Comprehensive alarm and monitoring functionality gives the operator constant feedback on the status of the system and informs immediately in case of any operational or emergency alarm. In addition, the fully automatic, PLC-based system, which includes base-load switchover, is backed up by mechanical pressure switches for maximum supply continuity.

 

VACUUM PUMP

Oil-lubricated rotary vane vacuum pumps offer high flow capacities. They are simple and economical to install and operate, and are quiet and vibration free. They provide smooth, pulse-free vacuum and have low starting and running torque. The vanes are constructed from composite material for a long lifetime of use (up to ten years under normal operating conditions) and low noise levels.

MOTOR

Optimally sized to suit the demands of frequent starts found in medical applications, each motor is air-cooled by an integral fan and protected by an overload fitted within its pump control panel.

BACTERIAL FILTER

The high-efficiency bacterial filter elements have a penetra­tion of less than 0.0001% when measured to BS 3928 to mini­mise the likelihood of microbial contamination of the oil.Duplex filters are provided for redundancy.

VACUUM VESSEL

The vacuum vessel is a mandatory back-up in the rare occurrence that all vacuum pumps are down. It also acts as a buffer for peaks in the flow demand. Modular design of Schönn vacuum systems can be tailored exactly to any hospital's needs. At the core of the system, 2 to 3 oil-free or oil-lubricated pumps with performance ratings ranging from 0.25 kW to 18,5 kW provide the required vacuum at the specified redundancy level. All other system components, such as receivers, bacterial filters and secretion traps, are chosen to match the system dimensions. The PLC-based control panel can be programmed according to system configuration and operational demands to provide optimal system operation and satisfy individual hospital requirements. The Medical Vacuum Control monitors and switches the vacuum pumps to ensure an even aggregate load and alert you to any system malfunction as early as possible. Both control and alarm signals can be transferred to external systems via potential free contacts, or be fed directly.
