Installation Service

ContractorPakWe offer a full service or a supply equipment only or supply and final termination and commissioning service.

Our electricians are fully qualified and we have insurance in place for our products and installation.

Our pricing is very competitive and we base our quotations on location, number of nodes, i.e one sensor or warning device equals one node. Cable containment also has a part in the costing.

We have 35 years experience on installations, from construction sites, laboratory refurbishments, food factories and many other process and industrial sites.

We manage all projects in house, from initial conception, through equipment approval and manufacturing to first fix wiring and final equipment fitting and commissioning. We work closely with the client and the main contractor.

We have a substantial number of Facilities Management Companies on our client base and can work directly with these, if the end user client prefers.

CableWe prefGas-Monitoring-Equipmenter to supply the cable for all installations and also supply a wiring schematic table for all projects.

All cable supplied is low smoke halogen free specification.

The recommended height for the control panel is 130cm from finished floor level, FFL , on a system for oxygen depletion monitoring where LN2 or gaseous Nitrogen is used 120 cm FFL.

Where Argon is used in the workplace it is essential the sensors are mounted as clos to FFL as possible and if pits or voids below floor level are in the work area, additional sensors should be mounted as low as possible.

NMR and MRI Scanner Rooms

We have many installations Worldwide detecting the lack of oxygen in rooms where NMR machines and MRI body scanners are used.

Both these machine store Liquid Helium and Liquid Nitrogen for the operation of the super cooled magnets.

In the case of the MRI healthcare body scanners these have very powerful magnets and because of the magnets they have to be fitted within a room with a Faraday cage to stop electro-magnetic field escaping from the room.

These powerful magnetic waves cause problems with oxygen sensor transmitter signs output and causes errors on the monitor .

To overcome this problem we developed over 10 years ago our pneumatic sensor MRI interface panel.

ScannerMRI Scanner Interface Panel

The MRI scanner interface panel house two oxygen sensor transmitters which connect, as all our sensors with 4-20mA signal to the main control panel.

It also house two 24 V dc sample pumps, power supplies and plumbing.

The interface panel is mounted outside the Faraday cage with two 6mm polyurethane sample pipes routed to low level and high level in the MRI scanner room through the wave guides that are small tubes to allow electrical connections to MRI equipment.

These pipes are terminated in small ventilated housings , one at the highest level to detect the lack of oxygen from the possible build up of Helium, the low level one is mounted at 120cm FFL for oxygen depletion fro the leakage of LN2.

The main control panel then operates its normal way without any interference from the MRI scanners magnets.

NMRNMR Oxygen Depletion Monitoring

We have many year’s experience in supplying and maintaining oxygen depletion monitoring system in laboratories that support NMR machines.

Raymond Coupland Ltd win second order for oxygen depletion monitoring system for the King Abdullah University of Science and Technology in the Kingdom of Saudi Arabia.

In 2010 we supplied our first system for the Nuclear Magnetic Resonance Spectroscopy Laboratories, commonly known as NMR spectroscopy, these are a non-destructive analytical tool and one of the principal techniques used to obtain physical, chemical, and electronic structural information about molecules. NMR works by exploiting the magnetic properties of certain nuclei. The laboratory has been extended with an annex, and making in total one of the World’s largest arrays with 10 state of the art NMR spectrometers from Bruker.

These include one of the World’s first Bruker 900MHz Wide-Bore magnets which is dedicated to material science research, as well as the World’s first Bruker 500MHz Super-Wide-Bore magnet for imaging applications. The NMR facility at KAUST is also equipped with isolated floor slabs for vibration reduction, as well as its own in-house liquid nitrogen delivery system.

The extensive use of Liquid Nitrogen and Helium in the laboratory presents a risk of asphyxiation to the scientist and personnel.

Some of our systems are still operating after 25 years with just one annual service visit.

All our systems come with a two year warranty, if they are maintained annually by our company this is extended for 25 years.
