Standard Compliance
Specifications obtained at sea level using water as the recirculating fluid, at a +20°C process setpoint, +25°C ambient condition, at nominal operating voltage. Other fluids, fluid temperatures, ambient temperatures, altitude or operating voltages will affect performance. *Unit weight is for air-cooled units. Subtract 14 kg (30 lb) for water-cooled units. †This selection requires the global voltage option. **Add 12 kg (27 lb) to unit weight.
