The Kingtec SK1800D Diesel Transport Refrigeration Unit

The Kingtec SK1800D series is designed to outperform the competition while using less engine power. It is a paradigm shift to deliver more with less, and the SK series is the first to achieve and deliver higher refrigeration capacity, outstanding performance, and a greater fuel efficiency while using less power.

The SK1800 platform features a smarter large-displacement 2.2 liter engine equipped with enhanced sensors and an electronic control module. The engine continually communicates with SmartCool® control system to optimize performance and conserve power. The result: an ultra high-efficiency platform that generates higher capacity and performance using significantly less power. The SK1800 engines operate using fewer operating hours at lower speeds, increasing the SK1800 durability, reliability, and efficiency.
