Overview
The ConductScience VTS-30 Vaccine Transport System is a purpose-built,
battery-powered portable medical refrigerator/freezer designed for the transport and temporary
storage of vaccines, biologics, and temperature-sensitive medical products.
The VTS-30 integrates a compressor-based dual-mode cooling chassis, a 24V 150Ah LiFePO4
battery module, and an NIST-calibrated digital data logger into a single portable unit —
delivering autonomous cold chain capability for field deployment, emergency response, and
stockpile distribution.

Is the VTS-30 TAA compliant?
Yes. The VTS-30 is Trade Agreements Act (TAA) compliant. Substantial transformation is performed in the United States, and country of origin documentation is included with each unit.
What temperature ranges does the VTS-30 support?
The VTS-30 operates in two modes: Refrigerator mode (2-8 degrees C, programmable setpoint) and Freezer mode (-30 to -10 degrees C, default setpoint -20 degrees C). Temperature accuracy is within +/-0.5 degrees C across all ranges.
How long does the battery last on a full charge?
In refrigeration mode (2-8C), the integrated 24V LiFePO4 battery provides 60+ hours of runtime. In freezer mode (-20C setpoint), runtime is 12+ hours. Supporting documentation is available upon request.
Does the data logger have an exterior display?
Yes. The integrated DDL-51 data logger features a built-in LCD panel showing real-time temperature, max/min extremes, temperature history, cumulative excursion duration, and an Ok/Alarm status indicator -- all visible without opening the unit.
Is NIST-traceable calibration included with each unit?
Yes. Every VTS-30 ships with an individual 5-point NIST-traceable calibration certificate from an ISO/IEC 17025-accredited (A2LA) laboratory. Calibration is performed within 30 days prior to each delivery at points: +30C, +20C, +5C, -20C, -30C (within +/-0.5C tolerance).
Is the VTS-30 compliant with CDC/VFC cold chain guidelines?
Yes. The VTS-30 is designed to comply with CDC and VFC (Vaccines for Children) cold chain guidelines for the transport and temporary storage of vaccines and biologics.
Can the VTS-30 run on vehicle power?
Yes. In addition to standard AC power (110-240V, 50-60 Hz), the VTS-30 accepts 12V and 24V vehicle DC inputs. The unit switches seamlessly between AC, DC, and battery operation without interruption.
What alarms are included?
The VTS-30 includes audible buzzers and visual LEDs for: high temperature excursion, low temperature excursion, low battery warning (8+ hours remaining), and power failure. The LCD displays cumulative out-of-range time for both high and low excursions.
What is covered under the warranty?
The VTS-30 carries a 1-year parts and labor warranty from date of delivery, covering the cooling chassis, battery module, data logger, alarm system, power supply, cords, and hardware. Battery warranty is 1 year. Contact: support@conductscience.com or +1 847 983 3672.
What accessories are included with each unit?
Each VTS-30 ships with: AC power cord (110-240V), 12V vehicle DC cord, 24V vehicle DC cord, AC battery charger, operator manual, laminated quick operation guide, original NIST calibration certificate, and a qualification verification letter. An optional transport trolley is available upon request.
