Exceptional temperature control with a new dimension in performance and efficiency.

Built upon the proven X2™ platform, the X4™ series sets the bar even higher as the new industry standard for refrigeration performance and efficiency.


Higher Capacity

Up to 66,000 Btuh of cooling at AHRI rating conditions – while providing faster pulldown, precise temperature control and peace of mind for demanding applications.

Ultra High Efficiency

EcoFORWARD™ technologies deliver significant fuel savings as well as higher performance, achieving 35 to 50 percent more BTUs of cooling per gallon of fuel.

Compliance Plus

The unit provides compliance with 2013 EPA Tier 4 emissions regulations, while also improving operational efficiencies and performance.

APX Control System

The modular APX system combines control intelligence, temperature control and system reliability with amazingly simple operation.

Lower Cost of Ownership

Combining innovative engineering with a straightforward, practical design means less fuel consumption, reduced engine run hours and lower maintenance costs.

Proven Reliability

The enhanced platform now includes proven high efficiency components from our Vector series and an industry-leading warranty.
