APR Control: The 2-Stage, 3-Phase HVAC Equipment Alternative for R-454B

Solving the Challenge of 2-Stage, 3-Phase Equipment Availability for A2L Refrigerants

Engineers, contractors, and distributors alike are voicing frustration over the lack of 2-stage, 3-phase air conditioning equipment for the new A2L refrigerant systems, like R-454B, for 5 tons or less. With these units not yet being produced, meeting job specifications and seizing opportunities has become increasingly difficult.

Fortunately, there’s a cost-effective, readily available solution: the APR Control.

By pairing standard single-stage equipment with the APR Control, you can not only meet 2-stage specifications but outperform them. The APR Control fully compatible with the new A2L refrigerants offers greater turndown (capacity modulation) than traditional 2-stage compressors, delivering enhanced efficiency and comfort with true modulation capabilities.

This approach eliminates the need for expensive, hard-to-find equipment, avoids lengthy lead times, and provides substantial savings to your customers.

The APR Control Advantage for K-12 School Equipment Challenges

K-12 schools often seek 3-phase HVAC systems to ensure reduced energy costs, which helps minimize wiring requirements and lowers amperage use. However, the lack of available 2-stage, 3-phase equipment for smaller systems with R-454B creates a significant challenge for meeting these goals.

The APR Control provides an ideal alternative:

• By pairing single-stage equipment with the APR Control, schools can avoid lengthy lead times and significantly reduce upfront costs.
• Installation is simplified, as this approach eliminates the need for reworking wiring or making costly electrical modifications across multiple buildings.
• The APR Control ensures efficient capacity modulation, resulting in smoother operation, lower energy consumption, and greater comfort throughout classrooms and shared spaces.

This solution is perfect for schools looking to meet energy efficiency goals and maintain tighter budgets without sacrificing performance.

Reduce Delays and Boost System Longevity

Factory-installed hot gas reheat and other built-in humidity control features often delay project timelines. The APR Control achieves the same high-performance results without these added lead times or complexities. Plus, the APR Control is essentially maintenance-free and has been proven to extend compressor lifespan by reducing wear and tear through smoother operation and longer run times.
