EC1000 GAS INTERLOCK

The MWA EC1000 is an interlock between the ventilation system and the gas solenoid valve. The gas solenoid valve will not open unless the fans are on or the air flow is below set levels. The interlock system Complies with all Corgi gas regulations for commercial kitchens and provides complete compliance with BS6173. There is clear indication for gas on
and power on with a wipe clean fascia ideal for kitchen environments. The EC1000 comes complete with the gas interlock unit, air differential pressure switch's & fitting kits for two fans and an emergency panic button. Clearly marked terminals make this gas interlock system extremely easy to install.

EC4000 GAS INTERLOCK

The MWA EC4000 gas interlock has the same features as the EC1000 gas interlock but with up to four fan connections for the larger commercial kitchen.

Ventillation

GAS PROVING SYSTEM WITH VENTILATION INTERLOCK

The gas proving & fan interlock system ensures that the ventilation is on and there is no gas escaping to atmosphere before the gas solenoid valve is opened. Very easy to use with an LCD display on the gas proving panel giving the operator solutions and not just LED indications.
The LCD panel tells the operator the status and what to do in the event of any failures or problems. This gas proving system utilises a true differential pressure across the gas solenoid valve and fan failure bypass to meet Corgi & HSE guidance. Gas will not be available in the kitchen unless any mechanical ventilation is switched on, this is achieved by a 2 channel current monitor connected to the gas proving panel which is more reliable than air differential pressure switches. The unit has electronic pressure measuring technology, measuring true differential pressure on both sides of the gas solenoid valve. The gas proving system will ensure the gas supply cannot be turned on if there is a gas leak.
