The EMS120 emergency mixing valve assembly has been updated to include the new 521325 model of Watermarked tempering valves. With the 2x 25mm tempering valves used in this configuration, it allows a flow of 120 l/min at 70kPa pressure loss, thereby significantly reducing the required supply pressure compared to the previous EMS90 model, as well as providing a set temperature range better suited to emergency shower applications.
The assembly will provide thermal shutdown upon failure of the cold water supply to avoid scalding, however, in the case of a hot water failure the cold water bypass design
allows for cold water only to flow through the assembly in the event of
heated water supply failure to the mixing valves. This feature has been
integrated to ensure the functionality and integrity of the emergency
shower is maintained.
The cold water bypass valve requires a minimum of 20kPa pressure loss to achieve 76 l/min as required as AS4775. With the 70kPa required by the mixing valves for maximum flow rates, it is therefore suggested that a minimum of 90kPa dynamic pressure is provided for the correct operation of this product. Please note that sufficient pressure is ALSO required to provide a minimum of 210kPa after the
assembly to the emergency fixtures to comply with AS4775.
The EMS120 assembly is plumbed into a 304SS enclosures with a hinged door. The overall dimensions of the box is 850H x 420W x 127D and can be semi-recessed into a wall. The lid depth can also be adjusted for easier mounting in various wall cavities.
