Key Features
•SmartPower Electric Standby: An optional electric motor (15-20 hp) lets the unit run on 230V or 460V grid power when parked, cutting fuel costs and emissions. A high-output version boosts cooling capacity slightly for demanding conditions.
•CYCLE-SENTRY: This start-stop mode cycles the engine off when the setpoint is reached, saving 20-30% on fuel during lighter loads or stable climates.
•Defrost System: Hot gas from the compressor clears evaporator ice buildup, triggered manually or automatically via the SR-3 controller—essential for subzero operations.
•Acoustic Package: An optional sound-dampening kit reduces noise from ~68 dB(A) to the low 60s, ideal for urban deliveries.
•EMI-3000: Extended maintenance intervals (up to 3,000 hours) with premium oil and filters lower service frequency and costs.
Performance Capabilities
The SB-230’s cooling capacity varies by mode and conditions:
•Diesel Operation: At a 35°F setpoint and 100°F ambient temperature, it delivers ~23,000 BTU/hr; at 0°F setpoint, ~13,000 BTU/hr.
•Electric Standby: Similar outputs, slightly higher with the high-output option (exact figures depend on configuration).
•Heating: Approximately 12,000 BTU/hr, sufficient for frost protection in winter.
Airflow (~3,500 CFM) ensures uniform cooling across large trailers, while the ETV and CYCLE-SENTRY enhance efficiency. Fuel consumption averages 1-2 gallons per hour on diesel, less in stop-start mode. Noise levels hover around 65-70 dB(A) without the acoustic package—moderate for a diesel TRU.
