WCSLRB Water Cooled Load Banks
Water Cooled Load Banks ZENITHSUN WC

SLRB water-cooled load banks built on water-cooled resistors: 3 kW – 5 MW, 5–1,000 V AC or DC, 0.1–15,000 A. Cooled by flowing tap water, distilled water or other liquid — no deionized-water costs; for the same power the cabinet is lower than an air-cooled one: 50 kW — 700 × 650 × 800 mm versus 680 × 680 × 1,200 mm. Cooling system, pump, tank, cooling tower and piping available on request. RS232/RS485, short-circuit, overload and over-temperature protection. Examples include 400 kW / 1 kV, 770 kW in stainless steel and 96 kW / 400 V DC.
