COMPRESSORS
Six reasons to choose a VSC
Decrease energy consumption by up to 33% in refrigeration with a variable speed compressor and five other reasons why transitioning to a VSC today is a smart business decision for contractors and their retail clients, regardless of which way regulatory winds may blow tomorrow, according to John Prall, technical support engineer at Embraco.
T
he environmental and industry consensus surrounding HVACR sector can change quickly as political winds shift, leaving contractors and their commercial clients burdened with wide-ranging uncertainty on how to best solve refrigeration needs – both in the immediate future and down the road.
As we wait to see how various policies play out, here’s one thing we can all agree on: No one wants to build their business plans on a foundation of uncertainty.
Regardless of how future legislation impacts the industry, the motivation to upgrade refrigeration products can often transcend government-mandated requirements and instead be driven by a company’s brand DNA or financial considerations.
Aside from legal precedents and financial considerations, many of today’s businesses have the desire to lower energy consumption and reduce their direct impact on climate change. In fact, more than 45% of the Europe light commercial refrigeration market has made the switch to R-290, and more than a million R-290 compressors are in the European market today because of all the environmental — and, just as importantly, financial — benefits of making the switch.
While phasing out and upgrading legacy cooling systems with more efficient solutions can levy a significant upfront financial requirement, the right combination of HC refrigerants and a variable speed compressor can have an even more significant ROI and can pay for itself in as little as six months.
By transitioning their current refrigeration systems to a variable speed compressor (VSC) line paired with R-290 natural refrigerant, food retailers combine high energy efficiency, better

temperature stability and food preservation, low maintenance costs, and space optimization. Let’s take a deeper dive into six end-user benefits that business owners experience when switching from traditional on/off compressors to VSCs: Quicker ROI Through Realized Energy Savings Variable speed technology can pay for itself in the first six to 12 months of use. Here’s how: – When applied to vertical freezer equipment, a VSC can pay for itself in six months by reaching target temperature up to 70% faster than a single speed model with HC refrigerant, while saving up to 33% energy consumption.
– Transitioning a frozen island from on/off compressors and R-404A refrigerant to a combination of VSC and R-290 results in energy savings of 30%. This decrease in energy usage generates a payoff of the initial investment of the switch in less than 12 months.
Ongoing Savings After Initial Investment Payoff – In addition to initial ROI benefits, the ongoing energy savings will extend through the life of the product, freeing up more money for business owners to invest in more new refrigeration solutions.
Extension of Product Life – Variable speed compressors start at a lower speed and ramp up over a few minutes. This “soft start” dramatically reduces the starting currents of the motor — reducing stress, extending the machine’s lifespan, and helping to ensure businesses operate smoothly.
Increased Reliability – VSC systems don’t use start relays, start capacitors, and/or run capacitors, which are items that can fail in the field from simple
wear and tear, putting business owners at risk of suffering immediate financial losses and long-term damage to their customer relationships.
Faster Pull Down – Freezers that utilize VSCs recover much faster from the higher temperature delta between product temperatures and ambient temperatures, reducing the time the system spends removing the heat infiltration and minimizing pull down time.
Significant Noise Reduction – This one is pretty straightforward. No one wants a loud compressor.
At the end of the day, store owners should do what makes the most financial sense for their business and look to invest in more sustainable and flexible cooling solutions that save them money by decreasing energy consumption and increasing product lifespan and reliability. The rationale for contractors to recommend their clients transition to a combination of HC VSC combinations is twofold: The better business health that your clients are in, the more operational cash flow they’ll be able to allocate towards continued investment towards innovative cooling solutions, helping to future-proof both your businesses.
You’ll create a bond with your clients and earn their trust by demonstrating that you have the best interest – both short term and long - of their business in mind when recommending refrigeration solutions.
The benefits of saving money and limiting environmental impact ensure that retailers can maintain solid business footing regardless of uncertainty in future regulatory requirements.
