A Guide to Scavenging Gas Servicing


Organising regular scavenging gas servicing will ensure your equipment continues to work efficiently and remain in good condition for as long as possible.

In this month’s blog at Coltronics Systems Ltd we provide a guide to scavenging gas servicing. Call us in Staffordshire on 01827 319 966 for more information from our team.

About Anaesthetic Gas Scavenger Systems (AGSS)

Anaesthetic gas scavenger systems (AGSS) are used to remove waste gases from rooms in hospitals and veterinary surgeries to protect people and animals from harmful gases. These waste fumes can be hazardous even at low concentrations.

The systems are efficient, ensuring all operating theatres and other rooms comply with UK regulations. This includes keeping gas limits below 100 ppm for nitrous oxide, 10 ppm for halogenated volatile anaesthetic agents and 10 ppm for halothane.

Additionally, these systems can come with features such as remote alarm reporting and control panels. Consult a specialist to learn more about these features.

What Does Servicing Involve?

Regular servicing is essential to keep the system and its components in good condition. Professional servicing often includes:

  • Cleaning Components
  • Adjusting & Calibrating Settings
  • Diagnosing & Fixing Issues
  • Testing Equipment

Through these inspections, experts will ensure your equipment is working efficiently. They can diagnose and resolve a range of issues quickly, getting your system running again as soon as possible.

The Importance of Preventative Maintenance

To avoid expensive and time-consuming repairs or even replacements, investing in preventive maintenance is crucial. This can ensure that the scavenging gas systems are running efficiently and prevents any faults or damaged components from getting worse.

Annual routine servicing is the most effective way to keep your equipment in the best condition. Additional, organising regular inspections and servicing will ensure you have evidence of equipment maintenance for RCVS Accreditation.

BSAVA Sponsored Anaesthetic Gas Monitoring Scheme 

Coltronics Systems Ltd operates the Anaesthetic Gas Monitoring Scheme and has since May 1998. The COSHH Regulations require any organisations using Anaesthetic Agents to regularly check that the waste gas levels are within a specific limit when based on an 8-hour Time Weighted Average. 

The maximum legal occupational exposure limits for the most common agents used by veterinary professionals are: 

  • Halothane 10ppm 
  • Isoflurane 50ppm 
  • Sevoflurane 60ppm 
  • Nitrous Oxide 100ppm 

These limits are based on an 8-hour Time Weighted Average (TWA). The Health and Safety Executive recommends routine testing every 14 months, however, annual testing is more manageable.

At Coltronics Systems Ltd, we manufacture a range of compact general anaesthetic gas machines that are designed specifically for veterinary practices. These range from portable, wall-mount, table-top and hybrid.  They are good value and provide maximum versatility making them ideal for practices.

Why Oxygen Concentrators Need Scheduled Routine Service

Piped Oxygen Bottles

When you have oxygen concentrators for veterinary practices, scheduled routine service is needed. Routine services should restore the condition of your oxygen concentrators, also improving safety. For the best possible functionality, servicing is always essential.

Coltronics Systems Ltd provide a comprehensive service for our clients. Supplying, installing and servicing all oxygen concentrators you can depend on our team. You can have scheduled routine service whenever you require.

Benefits Of Scheduled Routine Service

After installing veterinary equipment and oxygen concentrators, maintenance and servicing may not be your top priority. However, having a scheduled routine service can be extremely beneficial in several ways. For you to retain the best quality, efficiency and overall performance, servicing should be in consideration. Just some of the benefits of servicing include:

  • Compliance With RCVS Accreditation Requirements
  • Keep Equipment In Peak Condition
  • Optimal Safety For Operators
  • Prevent Unplanned Equipment Failure

Without regular servicing, although your equipment should remain in good condition, its performance could drop. To keep your equipment in peak condition, prevent failures and maintain safety of the highest level, servicing is vital. Having regular servicing will prevent any problems with the equipment whilst reducing the chances of needing repairs and replacements. To meet all health and safety requirements and industry-standard, our servicing offers the perfect solution.

How Often Should I Service?

Annual servicing is usually the best option for a range of veterinary equipment. We would recommend this for most G/A machines, AGSS and veterinary medical gas systems. Unlike other equipment, you should service oxygen concentrators on runtime hours, meaning they do not always fall in line with calendar service schedules.

By having regular or annual servicing, the RCVS will accept proof of servicing so accreditation requirements are met. If you are unsure what performance or condition your concentrators are in, you can contact our team for advice. We make sure oxygen concentrators always deliver the best performance and servicing is available to restore their condition when necessary.

Equipment & Vaporises

As previously mentioned, scheduled routine services are available for any G/A machines, AGSS, veterinary medical gas systems and oxygen concentrators when required. Spare parts are also available so during servicing, replacement parts are available to restore their condition.

Unfortunately, vaporisers are not available for servicing as to clean them, they must be stripped down. Despite this, vaporisers can still be repaired or replaced if they no longer offer the performance you expect from them. To identify and monitor the calibration of vaporisers, we use high accuracy Infra-Red Refractometers. If vaporisers fail, factory reconditioned units will be used for replacement.

Autoclaves and X-ray machines are not available for servicing as they are a specialist skill and equipment. Despite this, we have fantastic relations with providers to deliver servicing of all equipment on the same day.

Cost Of Servicing

Despite it begin integral for all veterinary equipment, you might want to save money instead. However, the cost of servicing will maintain the performance and effectiveness of equipment whilst also improving durability and lifespan so repairs and replacements are unlikely in the future.

For a typical small animal practice, the cost would be £325.00 + VAT for the service, testing and certification of:

  • 2 G/A Machines
  • AGSS
  • Piped Oxygen
  • Vaporisers

This would also include any servicing of consumables but not manufacturers replacement parts. For additional servicing, engineers will quote you on the day after approving additional equipment, such as the manufacturers’ replacement parts.

When you require service, there should always be a competitive price available for both small and large practices with equipment on site. Additionally, practices who are in groups or have multiple branches receive special terms for the number of practices involved.

Should You Use Piped Oxygen Supply?

Deciding whether or not to use piped oxygen for veterinary machines is a question that troubles many of our customers. Both options offer their own benefits, meaning it can benefit certain practices more than others. However, it is important to consider both choices and what is best for you.

Coltronics Systems Ltd can advise all clients on your requirements and if piped oxygen supply is ideal for you. Supplying all veterinary equipment, your demands will be met by our team.

Bottled Gas CostsPiped Medical Air Installation - Coltronics Blog Jan

There are several bottle sizes available and choosing large, Size J Bottles can often be much more cost-effective than smaller Size E and Size F for veterinary G/A machines. It can be difficult to know which bottles offer the best cost as they contain three elements. The price is usually dependent on:

  • Delivery “Service Charge”
  • Monthly Bottle Rental Charges
  • The Cost Of The Actual Gas Fill In The Bottle

It is important to research the monthly gas costs of your own practice. Although we can advise you regarding the different prices and which option is best, knowing your own gas costs will be beneficial. If you are spending over £150 excluding VAT on a monthly basis, piped oxygen should always be considered. Doing this could give you an average cost saving of 25%.

By saving 25% per month on your gas costs, this could mean your oxygen system pays for itself within just 3-5 years for small animal practices.

Initial Oxygen System

Although piped oxygen is often the best solution for many veterinary practices, we would still advise startups to initially begin with bottled gas. Doing this will allow you to spend your main funds in other areas of the business first. This helps you gain money to then invest in piped oxygen supply and superior, more cost-effective oxygen systems.

This could also help you keep gas costs lower when starting up as it is likely you will be using less gas. Therefore, you will not have to order as frequently. This means gas systems can maintain their effectiveness and efficiency at a low cost. As the business continues to grow, installing oxygen pipes then becomes a viable option to save you money as you use more gas.

Considering Portable Oxygen Concentrators?

You should always be looking to regularly update your supply of oxygen to find the most cost-effective option for you. When using small bottles before piped oxygen systems, it can be worth using small portable oxygen concentrators. This can act as an intermediate step before using piping systems.

Similar to piped oxygen supply, this will typically pay for itself within a couple of years. The initial cost is around £750 – £1,200 each. This makes it ideal for smaller practices with two G/A machines. However, if you have funds available to switch completely to pipes, this can offer higher quality and durability in the long-term.

Why Choose Piped Oxygen

To Concentrate or Not To Concentrate?

Veterinary Medical Oxygen

To concentrate or not to concentrate – that is the question. When identifying ways to gather Veterinary Medical Oxygen, it is important to know all the benefits and drawbacks. Oxygen concentrators are a fantastic choice, but is it the right option for you?

Coltronics Systems Ltd supply a wide range of veterinary products throughout the UK. Your expectations will always be met with Veterinary Medical Oxygen we supply.

What Are Oxygen Concentrators?

When driving Veterinary Medical Oxygen, oxygen concentrators offer an ideal and attractive solution for most clients. Supplying oxygen of 93% purity by squashing out nitrogen competent, this is a massive benefit for Veterinary Medical Oxygen. This methodology is called “Pressure Swing Absorption”.

Before choosing oxygen concentrators, it is important to actually know what the best option is for your veterinary requirements. With 93% purity, oxygen concentrators quite clearly have their benefits. However, you must consider several factors before ordering these concentrators and also look at the best alternatives.

Should You Install Oxygen Concentrators?

Running any business, you have to know if this will be a cost-effective solution for you. If your current oxygen bill is over £300 per month, the likely savings of oxygen concentrators should pay for installation within a 3-5 year timescale. This will also depend on the installation you have and what products you actually want.

During the installation process, you can have a small, portable concentrator with each G/A machine installed or a central large concentrator. Ideally, the latter is best when you already have piped oxygen and if you do not, the smaller, portable concentrators should be used. Good ventilation is important for installation, with concentrators removing oxygen from the surrounding air.

Ongoing costs should help you save money but it is also important to have a backup bottle supply. Regardless of the system you decide on, this gives you peace of mind that if a problem does occur, oxygen is still in supply. You may need servicing and maintenance, whether this is on a regular basis or for specialist attention. Our team can help all users so you know how to use the system correctly and any adjustments are quick.

Using features such as airbricks and vent grills deliver the highest performance of concentrators and a long-term, cost-effective option.

Environmental Impact

When installed correctly and in  the right place, there shouldn’t be too much environmental impact. Larger installations are quite noisy and need to be located away from clinical areas. However, the smaller units are much quieter and can often be sited directly next to a G/A Machine.

These smaller machines are designed specifically for Human Home Oxygen Therapy. Hence, many of them do not develop enough pressure to drive a G/A machine properly. This means, despite being the nosier option, larger installations could be more ideals. If the portable unit has an output pressure of 0.3Bar (5psi), this should be enough. Some of the most effective portable units have over 0.75 Bar output pressure, giving you fantastic performance.

Supply & Savings

Supply will vary depending on the units you receive but the 93% oxygen purity will always be delivered with the machinery we install. For individual portable units, you need between 550 to 750 VA from a normal 13 Amp socket. Larger, stand-alone units will require 1.5KVA, allowing them to continue running from a standard socket. Some of the larger installations will only require a 415V supply.

Whilst oxygen concentrators should offer good savings for Veterinary Medical Oxygen, it is important to know the exact costs for this machinery. Portable units will run from about £750 to £1,200 for 5 to 10LPM flow capability. Alternatively, the larger units will start at around £5,900 up to £11,000 for a larger 10 to 30LPM capability at Pipeline Pressure.

We talk you through the best option for your specific needs. With both oxygen concentrator options, you can expect savings of around 40% to 60% of your current cost. This gives you fantastic savings in the long run to pay for installation.
