Embraco

SELECTING THE RIGHT COMPRESSOR

Embraco has been at the forefront of cooling solutions for the last 48 years, setting the global benchmark in quality, technical excellence, and practical, sustainable innovation for the refrigeration industry.

One in five compressors in the world are manufactured by Embraco, and we take that responsibility seriously. Business owners, OEMs and contractors choose Embraco because our products are developed with a commitment to innovation partnership, and a conscious effort to give people a better quality of life. We prioritize continued research and development so that we can offer efficient, cost-saving, and sustainable compressors and cooling solutions, such as condensing units and sealed units ranging from 1/8 to 2HP, of the worldwide market.

Fixed Speed Compressors (ON-OFF)

For many years the Fixed Speed compressor model, commonly known as the ON-OFF compressor, stood alone in the refrigeration industry. It has a time-tested, straight-forward design and impressive versatility and reliability. ON-OFF compressors are at work inside a range of common appliances, from your home refrigerator to drinking fountains, ice makers, beverage coolers and large commercial refrigeration cabinets.

The Embraco ON-OFF hermetic reciprocating compressor pulls refrigerant from the evaporator, increases the vapor pressure and discharges the refrigerant to the condenser. It switches off and on depending on the temperature of the refrigerator, running at a single speed during each cycle. Similarly, it pumps refrigerant throughout the system when activated— it’s either on or off, or in our case, removing heat from the refrigerator or not.

Our traditional ON-OFF products have been in the market for decades, but we’re still committed to continuous innovation in the market. Embraco currently holds over 1,200 patents in cooling and refrigeration, has 47 laboratories in 4 continents and employs over 500 engineers and technicians dedicated to R&D. Continuous improvements in the quality and control of our production processes has increased the energy efficiency of our compressors by 30-40% over the years.

Since sustainability is one of our primary values, we work not only to minimize the environmental impact of our supply chain and production standards, but to develop highly energy efficient solutions and also lead the introduction of natural refrigerants in the refrigeration market.

Variable Speed Compressors (VSC)

Embraco’s variable speed compressor uses our proprietary Fullmotion technology. Different than the ON-OFF model, a VSC reduces energy consumption by adjusting its speed to match fluctuating cooling demands. Fullmotion technology reduces energy consumption by up to 25% when compared to ON-OFF technology. The different speeds help each unit reach its target temperature faster by speeding up when necessary and slowing down when demands are lower, such as outside hours of operation. This process also helps stabilize the internal temperature of each unit, providing a safer and more suitable environment for applications such as foodservice and medical. 

Fullmotion technology reduces compressor noise as well, replacing the recognizable click and hum of your refrigerator turning on with a soft start and a steady low speed. Every model we design is built to be reliable, safe, and maintain performance integrity despite energy requirement and current fluctuations.

Our variable speed compressor does more than reduce operating costs—it maximizes food storage capability, saving more food with less energy in millions of homes and businesses across the globe. That’s real value.

We have a wide range of residential and commercial compressors for low to high back pressure applications ready for R-600a and R-290 (propane) refrigerants. The adoption of hydrocarbon refrigerant minimizes direct and indirect impacts on climate change due to the extremely low GWP of the refrigerant, reduced compressor footprint and enhanced energy efficiency of the system.

Identifying the Right Pressure Level for Your Application

Embraco compressors are classified into two different motor types:

  • LST (Low starting torque) – Appropriate for systems with a capillary tube expansion-type device and equalized pressure on start up.

  • HST (High starting torque) – Appropriate for systems with expansion valve or capillary tube expansion-type device with disequalized pressure on start up.

They are also classified into three different pressure levels, LBP, MBP, and HBP:

  • LBP (Low Back Pressure) – Low evaporation temperature.

  • MBP (Medium back pressure) – Average evaporation temperature.

  • HBP (High back pressure) – High evaporation temperature.
