Model TWBS.EW.H An 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).

• It is ideal for areas where supply water temperatures fall below 60° F (15° C) while hot water is not present
• System consists of an 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 (optional 208/240 3-phase available – ask for quote).
• UL listed for indoor use only.

The Haws Model 9321 Tankless Heater Solution, an electric water heating system designed to eliminate the need for large water storage tanks, as well as the continuous energy demand to maintain them at higher temperatures. This system will provide safety showers and eyewashes with an unlimited supply of tepid water with flow rates up to 30 gpm, eliminating the “recovery time” needed to reheat large storage tanks after use. Unit measures 18″ H x 27″ W x 11″ D. Unit is designed to be wall mounted.

The Haws Model 9326 Tankless Heater Solution, an electric water heating system designed to eliminate the need for large water storage tanks, as well as the continuous energy demand to maintain them at higher temperatures. This instantaneous eyewash water heater will provide safety showers and eyewashes with an unlimited supply of tepid water with flow rates up to 30 gpm, eliminating the “recovery time” needed to reheat large storage tanks after use. Manufactured with NSF-61 listed materials. Unit measures 30″ x 24″ x 13.5″. For all options, the cabinet will measure 30″ x 36″ x 17.3″.

The Haws Model 9327 Tankless Heater Solution, an electric water heating system enclosed in a stainless steel NEMA4X rated cabinet, designed to eliminate the need for large water storage tanks, as well as the continuous energy demand to maintain them at higher temperatures. This system will provide safety showers and eyewashes with an unlimited supply of tepid water, eliminating the “recovery time” needed to reheat large storage tanks after use. Unit measures 30″ x 24″ x 13.5″. For all options, the cabinet will measure 30″ x 36″ x 17.3″.

The Haws 9400 AXION® Steam Water Heater replaces hot water tanks when pressurized steam is available. When an emergency shower or eyewash is activated, the flow of water opens a steam control valve. The steam enters a brazed plate heat exchanger, instantly heating the water. This mixing valve blends hot and cold water to produce an output of 80° F (27° C ) tepid water. Additional valves keep the system preheated, freeze protected and scald protected. The steam valve will remain closed should there be a loss of water pressure. This station complies with the ANSI Z358.1 standard and mixing valve is designed to meet ASSE 1071

Model 8780 skid-mounted tempering system is the heart of the Haws Integrated tempering solutions line, offering a wide range of options to apply the equipment to an extensive range of water tempering solutions. The 8780 tempering skid mixes it’s pre-heated water supply in its onboard storage tank with low temperature facility water through its Haws Tempered Water Blending System, to produce an ANSI compliant water supply for all safety equipment in the plumbed system. Included is an aluminum 5′ x 5′ (1.5 x 1.5 m) frame with a composite equipment platform, with HYTEX Black chemical and UV resistant polyester based powder coating. This multiple shower and eyewash feeder provides an operating temperature range of 35° to 120° F (45.5° to 48.9° C), and is designed to operate with a number of tempering and electrical options. The standard tempered water blending system includes a 318 gallon hot water tank with 480V 1ph, and will incorporate fail-safe features like anti-scald protection and full flow cold water bypass. The electrical system can be easily adapted to voltages upon request.

• Standardized platform provides shorter lead times and customizable configuration options
• Ready-to-incorporate design variations including hot water supply, electrical type, blending capabilities, stainless steel piping, and more
• Optional VFD/Pump package for recirculation and/or pressure boosting applications

Model 8785 enclosed tempering system can be placed into any environment. Whether the intent is the protect the equipment from dirty or contaminated environments, shield from unpredictable outdoor weather, or provide a heated/cooled enclosure in extreme temperature installations the 8785 is your go-to choice for a rugged yet flexible water tempering skid solution. It shall include an all-weather 5′ x 5′ (1.52 x 1.52m) booth which provides optional operating temperature ranges of -50° to 120° F (-45.5° to 49.8° C), and is constructed of corrosion resistant aluminum paneling with polyester based powder coating. This single or multiple showers and/or eyewash tempering water unit with galvanized piping is designed to operate with several tempering and electrical options. Standard hook-up is a 480V, three phase inlet inside a NEMA 4 enclosure. The internal booth temperature can be maintained by an optional space heater. The tank water temperature is maintained by an immersion heater. The electrical system can be easily adapted to voltages upon request. The 8785 tempering booth utilizes the Haws Tempered Water Blending System to provide tempered water under dire situations, and incorporates fail-safe features like anti-scald protection and full flow cold water bypass in the event of hot water failure. 1-1/2″ tepid and cold water inlets.
