Gas Safety Week! – The essential list to ensure safety!
DMS have put together the ‘essential’ list of the products to ensure maximum safety on your application. Before we go over our recommended products, let’s take a look at the top tips to remember when selecting or installing a gas appliance:
Top tips to stay gas safe:
1. Use a gas registered engineer to install, service and fix any gas products
2. Keep on top of gas appliances safety checks
3. Be aware of the signs of carbon monoxide (CO) poisoning – headaches, dizziness, breathlessness, nausea, collapse and loss of consciousness.
DMS’s recommended products for gas safety:
Sapphire Gas Safety Shut Off Valves
DMS supply the range of Gas Safety shut off valves, available in sizes DN15 – DN150.
The Sapphire valves are installed in the pipework and programmed to stop the supply of gas in a situation such as a fire alarm or emergency knock off button being activated. Should the situation occur where the alarm is triggered and the power is cut, the valves will close rapidly impeding any gas supply. Once the system has been determined as safe and the power is restored, the valve will reopen and return to normal flow. The coils used for the Sapphire valves are powered by a 230v mains but we can also offer 24v if required.
The Sapphire Gas Safety Valves are powered open valves, meaning once power is present the valve is programmed to stay open, and close on trigger of alarm as standard. On special request the valve
Gas governors can be supplied to assist with lower any gas pressures if required – please enquire for more details.
DMS supply Elster Gas Regulators including; J48, J78, J125, J123. The most commonly used Regulator is the J48 - the J48 is a widely used product, working to control Low Pressure installations to the highest quality. The J48 uses an internal impulse to sense the inlet pressure of gas entering and act accordingly to supply the original outlet pressure set. The J48s are available with a threaded BSP Female connection from 20mm up to 80mm and with a Flanged PN16 connection from 65mm up to 150mm. All J48 regulators can be installed in either horizontal or vertical runs of pipework.
Chatterbox – The Dresser Chatterbox-e Isolation Unit is a vital piece of equipment for plant rooms with a high-risk environment. The Chatterbox uses Opto-isolators to provide 4 isolated volt-free contacts from low-frequency pulses generated by gas meters or volume correctors installed in a hazardous area as standard. The Chatterbox can be installed without the use of mains power, promising a 10-year battery life from just standard cells – two ½ AA lithium. Once installed the Isolation unit can be set up for use with up to 4 different channels by wiring the pulse cables into the internals of the aluminium-bodied chatterbox. Adding the Dresser Chatterbox-e to your gas application can increase reliability and reduce power consumption thanks to its opto-isolation technology.
A crucial piece of equipment! Knock off valves will cut any power, in the event of a fire or emergency, the button is pressed and the system will shut down. Prices for knock off buttons can be obtained by contacting the DMS sales team.
Finally, and what we believe to be the most important thing to remember is…
ALL gas products should be fitted, serviced and fixed by a certified gas safe registered engineer.
