Please forward this error screen to sharedip-1601535267. 1-2014 for tepid water delivery to an emergency drench system. 3″ thick polyurethane foam to minimize stand-by heat loss. The entire package including the mixing valve is factory piped and mounted to the water heater to provide single source responsibility. When you specify and install a Hubbell Model EMV, you will have the confidence in knowing that the owner will be provided with a long lasting, safe and dependable source of tepid water for their emergency drench system needs. The valve is factory mounted and piped to the water heater.
F water in the tank with incoming cold water. F output regardless of inlet pressure and temperature variations, and the temperature setting is tamper proof and cannot be inadvertently adjusted in the field. The water temperature is not warm enough to open skin pores and not cold enough to deter usage. The valve is capable of providing a full range of flows from the smallest flow of 0. 4 GPM for an eyewash to the combined 23 GPM flow for a simultaneous demand of shower, eyewash, and face wash system. The mixing valve incorporates a pressure sensing controller with a valve actuator that senses the water pressure on both the hot and cold water inlet connections.
If hot water pressure is not present then the actuator overrides the mixing valve and a flow of cold water is allowed. If no cold-water pressure is available at the mixing valve inlet then the hot water port will close to prevent overheated water from exiting the mixing valve. The valve also includes a safety override feature that continuously senses the final mixed water temperature. If the final water temperature is overheated, the valve automatically closes the hot water port and fully opens the cold water port. In any of these fault conditions, the Hubbell EMV valve will continue to provide a full flow of water as per the ANSI standard with no additional pressure drop. When the eyes or body of any person may be exposed to injurious corrosive, toxic, or flammable materials, suitable facilities for quick drenching or flushing of the eyes and body shall be provided within the work area for immediate emergency use.
Delivered flushing fluid temperature shall be tepid. This standard also establishes minimum performance and use requirements for eyewash and shower equipment for the emergency treatment of the eyes or body of a person who has been exposed to injurious materials. The eyewash must have a minimum of 0. How Does the Hubbell Unit Achieve these requirements?
The volume of water at this temperature is necessary to achieve the final flow rate of 23 GPM for 16 minutes of tepid water. The carbon steel tank is internally lined with specially formulated hydrastone cement and does not require anodic protection. This lining is critical to the longevity of the tank when storing hot water at elevated temperatures. The mixing valve is specifically designed for emergency safety drench systems and is factory piped and packaged with the water heater tank to simplify installation and ensure a safe and dependable system. This provides the owner with a highly efficient and economical solution for emergency drench systems. Unlike instantaneous heaters, the Hubbell model EMV is unaffected by the loss of electric power in its ability to provide tepid water. Furthermore, the dial temperature gauge provides the operator with positive visual verification that the unit is at temperature.
F water for 15 minutes. Alternate storage capacities are available for smaller or larger requirements. Explosion resistant construction for installation in a hazardous location. Standard is Class 1 Division 2, Group B.
