Indoor Emergency Water Tempering Skid
Haws 8780
PERFORMANCE SERIES: Model 8780 standard skid-mounted tempering system which may supply a number of drench systems or eyewash stations. This unit is supplied with a 5' x 5' (1.52 x 1.52 m) membrane encapsulated, fiberglass channel reinforced wooden structure with bright yellow elastomeric chemically resistant waterproof coating, and protected with UV inhibitors provides an operating temperature range of 40° to 100° F (4° to 37° C). This single or multiple shower and/or eyewash feeder is designed to operate with a number of tempering and electrical options. The TWBS.HF tempered water blending system includes an integral hot water supply, whether stored or supplied by steam, and will incorporate fail-safe features like anti-scald protection and full flow cold water bypass. System piping includes Schedule 40 galvanized piping with brass and stainless steel valves.
Specify tempering booth models as follows: a model number, tempering system option, electrical system option. Standard electrical system is equipped with 480V 3ph, and is easily adapted for other voltages upon request. Example: Model 8780.22.32 is a Model 8780 Tempering Booth equipped with 119 gallon (450 L) ASME tank, and a Class 1, Division 2, Group B, C, D, T2D electrical system. For a complete list of options, refer to the specification sheet.
QUALITY CONTROL Fully assembled and tested for quick placement and hook-up.
