Haws TWBS.EW.H Instantaneous Heater For Eyewash Station
Availability : Usually Ships in 5 Business Days
Prepackaged Instantaneous Electrical Water Heater, 480 Vac/3 Phase/18 Kw, Fully Engineered And Tested System With Fail-Safe Features To Produce Up To 2.5 GPM Tempered Water For Eye Washes
Model TWBS.EW.H on-demand, prepackaged, fully engineered and tested tempering system to provide tempered water instantaneously. System is designed to increase cold water temperature by as much as 45°F (25°C) at 2.5 gpm flow; thus it is suitable for single eyewash application. Outlet water temperature is factory set at 80°F (26°C). System consists of an 18 KW electrical instantaneous water heater, a hot shutoff valve, a bypass valve, an in-line 50-micron filter, and an outlet temperature gauge. Maximum inlet pressure: 125 psi. Inlet and Outlet: 1/2" IPS. Electrical Supply: 480/277 VAC, 3-phase, 4 wire and ground. 25 amp electrical supply. (480 VAC, 3-phase, 3 wire and ground available as special order). FOR INDOOR USE ONLY.
FEATURES & BENEFITS
CONVENIENCE
Have the capability of on-demand hot water without the need of a large storage tank by incorporating this instantaneous water heater system.
SAFETY
Fail-safe measures include hot water shut off if the cold water supply is interrupted, and a cold-water bypass mode should the hot water get cut off.
SPECIFICATIONS
Model TWBS.EW.H on-demand, prepackaged, fully engineered and tested tempering system to provide tempered water instantaneously. System is designed to increase cold water temperature by a minimum of 34° F (19° C) at 4 gpm (15.1 L) flow and 68° F (38° C) at 2.0 gpm (7.5 L); thus it is suitable for single eyewash application. Outlet water temperature is factory set at 80° F (26° C). System consists of a UL listed 20 KW electrical instantaneous water heater, a hot shutoff valve, a bypass valve, an in-line 50 x 50 mesh filter, and an outlet temperature gauge. Requires 45 - 90 psi (3 - 6 ATM) flowing pressure. Inlet and Outlet: 1/2" IPS. Electrical Supply: 480 VAC, 3-phase, 3 wire and ground. 24 Amp per Phase. FOR INDOOR USE ONLY.
APPLICATIONS
Where the eyes of any person may be exposed to injurious or corrosive materials, emergency facilities for quick drenching or flushing of the eyes and body with tempered water is needed to compensate for less than suitable ambient temperatures, or when the supply water reaches freezing cold or scalding hot temperatures.
