New Karcher HD 4.5/32-4 S Ec Super Class Electric Cold Water Pressure Washer
Our Take (from the SES Sales Team)
“The HD 4.5/32-4 S Ec is the 440-460 V version of Kärcher's Super Class upright washer, for manufacturing plants, processing facilities and large municipal or fleet garages where three-phase 460 V power is already at the wash area. At 14 A it draws far less current than the 230 V Eb, and it delivers up to 4.5 gpm at 3,200 psi, adjustable at the machine down to 435 psi and 2.2 gpm.
It is built for long run times: a low-speed, 4-pole, air-cooled 10 hp motor with protection against voltage swings and overheating, and a 3-piston axial pump with a brass cylinder head, stainless valves and ceramic-coated pistons, guarded by a pressure switch and overflow valve. Kärcher rates it at 72 dB(A), and the upright frame has large wheels, a rear tilting aid, a lance holder and a cable and hose rack.
The trade-off is that it only fits sites with 440-460 V three-phase service and a 16 A slow-blow circuit. At about 137 lb it is a machine for a fixed wash area rather than a truck.”
Upright 460 V three-phase cold water washer for plant wash areas.
The Kärcher HD 4.5/32-4 S Ec (1.286-910.0) is an electric cold water pressure washer from the HD Super Class. A 10 hp, low-speed 4-pole air-cooled motor on 440-460 V three-phase power drives a Kärcher 3-piston axial pump with a brass cylinder head, stainless valves and ceramic-coated pistons. Flow and pressure adjust at the machine from 2.2 to 4.5 gpm and 435 to 3,200 psi.
A pressure switch and overflow valve protect the pump, and built-in motor protection guards against voltage fluctuations and excessive temperatures. The upright frame has large wheels, a rear tilting aid, an integrated lance holder, a parking position for short breaks and a rear cable and hose rack. It comes with an EASY!Force trigger gun, a 41 in spray lance, a 055 power nozzle and a 50 ft EASY!Lock hose with ANTI!Twist.
