Model TWBS.EW.H, prepackaged instantaneous electrical water heater, 480 VAC/3 phase/20 kW, fully engineered and tested system with fail-safe features to produce up to 6 gpm (22.7 L) tempered water for eye washes.
Model TWBS.HF (patent pending) is a thermostatic mixing valve that mixes hot and cold water to supply tempered water to emergency shower and eyewash fixtures requiring flow up to 78 gpm (295 L). Unit employs a paraffin filled thermostatic mixing element with triple redundant anti-scald protection. Lowest internal pressure drop where supply pressure is low, and a high Cold Water Bypass flow rate of 79 gpm (299 L). The improved low lead brass design with a one piece casting uses internal check stops, over-sized valve seats, a shuttle design that eliminates valve sticking, and a funnel design to improve temperature control with better mixing at low flow rates. Lime and calcium resistant components are used throughout. The outlet temperature factory setting is 85° F (26° C). Maximum operating pressure: 125 psi (8.62 Bar). Temperature adjustment range 60 - 90° F (16 - 35° C). Maximum inlet temperature: 180° F (82° C). Recommended inlet temperature: 140° F (60° C). Minimum inlet temperature: 120° F (49° C) Inlet 2" NPT(F). Outlet 2" NPT(F).
