The SKYTECH 450 GPM (1700LPM) Hydrant Cart is built on an aluminium chassis/Trolley, Towable Type. All piping is stainless or custom aluminium designed for longer life and faster flow rates. Also, this cart meets or exceeds NFPA 407standards and is fully zoned compliant to EI standards or customer demand standard. All of our equipment comes with an aluminium vessel, filter water separator or filter monitor, so there is no epoxy and less maintenance.
