Significant advances in therapeutic uses of medical gases have resulted in increased medical gas usage for a number of diverse clinical applications. Hospitals generally have large annual consumption levels of oxygen so bulk liquid is a very cost effective and convenient supply option.
Oxygen liquefies at -183°C and to keep it this cold a specific type of container is needed. Other than cost considerations, there are additional advantages to keeping oxygen in liquid form. In particular, it requires minimal maintenance and is easy to access and use.
BOC Healthcare can supply liquid oxygen containers of suitable capacity to match the demands of any healthcare establishment in accordance with the requirements and recommendations of HTM 02-01. This equipment includes:
- storage vessels
- control/monitoring panels,
- all necessary piping to the BOC termination point and connection to the hospitals Medical Gas Pipeline System (MGPS).
Vacuum Insulated Evaporator (VIE)
A VIE is a special vessel which could be described as a giant thermos flask - and, indeed, employs the same principles. VIE tanks are located outside hospital buildings and BOC tankers regularly deliver to top up the tanks, generally without the need to ring and place an order. Oxygen is drawn off as needed, passed through a vaporiser and turned into a gas before it is piped to individual wards.
A control panel regulates the flow of the gas from the VIE before it enters the hospital pipework. This is an essential safety feature, and an area where BOC’s expertise and experience is second to none.
Selecting the right VIE solution
Life saving oxygen supply is of critical importance to a hospital. Whether you have a VIE already and are considering re-sizing, or installing one for the first time, you need to ensure you have the right system supported by an experienced and reliable supplier. Either way, the decisions you make are vital as these types of installation are complex and can be expensive so you will need to be well informed and well advised.
There are different types and sizes of vessel and a range of factors are involved in making the right selection including:
risks to continuity of supply
current oxygen consumption levels
your future needs
Hospital Technical Memorandum (HTM) 02 guidelines
practical issues - such as planning permission, site access, environmental/planning restrictions and security.
BOC healthcare supplies a complete range of VIE vessels to meet any requirement. There are more than 50 sizes of vessel to choose from. The sizes generally fall into four categories:
|Water Capacity||Liquid oxygen capacity (HCM)||Weight of full VIE (Tonnes)|
|Small 1600 - 3000 litres||13.5 - 25.9||4.6 - 7.1|
|Medium 3200 - 8300 litres||26.6 - 70.2||6.3 - 16.7|
|Large 10,200 - 18,400 litres||88.2 - 155.4||21.0 - 34.7|
|Super-vessel 18,700 - 107,700 litres||156.9 - 904.3||31.6 - 171.5|
BOC Healthcare has access to all levels of engineering expertise necessary to provide Trusts with a comprehensive advice and installation service.
Support and maintenance
Regular oxygen top up deliveries are pre-arranged at a frequency to suit consumptions patterns. Additionally remote monitoring can be provided with Tel-Tank telemetry which automatically collects consumption data directly from your VIE and sends this to our delivery planning centre so that our delivery schedule can be fine-tuned to meet your exact requirements.
Our 24 hour liquid delivery centre provides reliability and peace of mind for customers in the healthcare sector, knowing that we have the resources and capability to maintain adequate supply for both predictable consumption and emergency (disaster) situations.
Product quality assurance
BOC treats product quality seriously, because we understand the impact it could have for your patients. Our products are produced under Good Manufacturing Practice (GMP) and are classified as a medicinal product. We therefore ensure that our production plants are continuously monitored, our product is analysed before it reaches the storage vessels and is tested again before we leave an installation.
Maintenance and reliability
Planned Preventative Maintenance is carried out on a regular basis by BOC’s own engineers to keep all equipment fully maintained to legislative requirements. We operate a 24 hours a day advice and technical assistance service, as well as an unrivalled 4 hour emergency breakdown response.
Safety first and last
Your safety is our number one priority. BOC has a dedicated force of trained professional drivers and engineers to manage your safety during installation and at every delivery thereafter, with the support of well proven policies and procedures including Permit to work, method statements etc.
Customer safety training is provided at the time of installation handover to ensure that all aspects of gas safety are covered on your site. Further Approved Person training courses are available from BOC to ensure consistent training of site personnel
