Precise Modulation & Efficiency: Meet the New Embraco Pulse Scroll

Building on our strategic expansion into the HVAC&R segments, we are proud to extend our scroll portfolio beyond fixed-speed solutions with our newest entry: the Embraco Pulse.

This digital variable-capacity scroll compressor was engineered specifically to meet the rigorous demands of modern refrigeration and heating applications ranging from 2 to 15 HP.

The Technology: Digital Modulation

The Embraco Pulse features a digital control mechanism that modulates its output by cycling between a full compression state and a zero-compression (unloaded) state in a typical 20-second rhythm. This allows for precise capacity adjustments from 10% to 100%, ensuring that output matches the load demand at any given moment.

Key Advantages for Your Systems:

• Stable Temperatures & Precision: The rapid modulation significantly reduces temperature fluctuations compared to traditional on-off cycling, ensuring consistent thermal control for critical applications like cold rooms and multi-deck reach-ins.

• Smarter Energy Use: The compressor consumes significantly lower power during the unloaded cycle. By dynamically adjusting the compression ratio, the system achieves higher partial load energy efficiency, reducing overall operating costs.

• Exceptional Acoustics: The Embraco Pulse utilizes a unique loading and unloading mechanism that delivers one of the lowest noise levels available in this technology, further supported by a dual discharge valve that prevents high-pressure gas return and shutdown noise.

• Enhanced Reliability: By minimizing harsh start-stop cycles and utilizing internal overload protection, the Embraco Pulse protects against liquid refrigerant return and abnormal conditions, extending the equipment's lifespan.

Complete Solution

To simplify installation for technicians, the Embraco Pulse is delivered as a total solution package. This includes the compressor alongside the dedicated Pulse Controller, solenoid valves, and necessary pressure and temperature sensors/transducers.

Versatile Application

The lineup is multi-refrigerant, including standard options like R404A and R448A/R449A, as well as A2L refrigerants such as R454C and R455A to ensure compliance with evolving F-Gas regulations.
