Simply put, eCube® is an Energy-Saving Device for Commercial Refrigerators.
The eCube® Concept
eCube® consists of a food simulant contained in a double-skinned enclosure that mimics food temperature at approximately 10mm beneath the surface. With eCube®, the thermostat regulates the refrigeration temperature based upon food temperature rather than air temperature, thereby maintaining food at the proper temperature. When fitted to the thermostat sensor, which controls the compressor, eCube® significantly reduces the frequency of the refrigeration cycles which are now based on food temperature rather than fluctuating air temperature. By using eCube® as a cycle control mechanism, refrigeration cycles last longer but can be reduced by as much as 85%. For example, a Dairy Case cycles 3 minutes on, 2 minutes off = 12 cycles per hour. With eCube®, the cycles change to 8 minutes on, 7 minutes off = 4 cycles per hour; a 66.7% reduction in starts. As the start-up of a refrigerator compressor uses 3 times more power (i.e. start-up 12 amps, run 4 amps) considerable energy savings are achieved. In addition, the more efficient refrigeration cycle leads to a more efficient unit, which then leads to a colder storage area. Consequently, by re-adjusting the thermostat back to its normal temperature settings, there are further substantial energy savings, without compromising food safety and quality.

Save between 6% to 25% by reducing wasted energy at the meter and demand on the electric grid.
A ‘Now Solution’ for energy efficiency and smart grid.
The KVAR EC™ is a cost effective product that reduces electric consumption and spans through the residential, commercial and industrial markets, specifically all electrical service from 600 volts and below. The tangible results of using the KVAR ECs™ are real savings on energy bills, reduction in demand for electric utilities, decreased line losses and carbon emissions.
The KVAR Corp. holds a U.S. Patent for the method and apparatus to determine the specific amount of capacitance to bring power factor to unity, thus optimizing all inductive loads. To prove its reliability and savings, KVAR ECs™ have successfully been tested and received endorsements from NASA, Honeywell and SMT Engineering LLC., an independent third party. The KVAR EC™ is UL and CSA listed, CE certified and meets RoHS (Restriction on Hazardous Substances Directives). The RoHS compliance qualifies KVAR ECs™ as Green Products since all its electric and electronic components are compliant.
This means the passive units of fixed capacitors is made of linseed oil capacitors, as opposed to PCBs, the wiring and other components are also of premium grade. KVAR EC™ was designed for a 25 year life cycle.
Our KVAR Distributors guarantee 6% savings on residential products and the KVAR Corp. provides a 12 year warranty. Commercial and industrial KVAR ECs™ have a 5 year warranty and no product is deployed and commissioned unless they show a Return on Investment (ROI) of 3 years or less. With a large segment of clients that boast an ROI in terms of months only.
The KVAR Corp. patented scientific method and apparatus used to size the exact amount of capacitance required to bring power factor to unity, provides great accuracies and time to size efficiencies. The three KVAR sizing units available simplify the process of determining the amount of capacitance that is needed to optimize motor loads. There is no requirement for equipment charts, specifications and expansive modeling. The entire sizing process is conducted on-site by tuning the electrical system from the inductive equipment back through the electric utility meter.
The PF optimization of the electric system reduces energy consumption for the utility customer, reduces demand on the electric grid, and reduces line losses and carbon footprint. Once the electricians have completed the sizing procedure, they simply forward the requirements to our manufacturing plant in Daytona Beach and custom equipment is built to suit the on-site sizing that was conducted.
The KVAR Corp. also produces Commercial-Off-The-Shelf (COTS) KVAR ECs™. Our energy controllers reclaim, store and supply power to inductive motors and loads. Considering all induction loads consume two kinds of power: Reactive power and working power of kilowatt. The working power performs the work of the motor. The only function of reactive power is to develop the electromagnetic fields (EMFs) to ground the induction windings of the motor. The KVAR EC™ stores the reactive power needed to create EMFs within the inductive loads. As the motor operates, this reactive power is pulled and pushed to and from the KVAR EC™ by the motor. Reactive motor is now reclaimed and recycled by the KVAR EC™ resulting in such power being supplied on the spot. Since reactive power is supplied locally, motors run cooler and more efficiently. This results in dollar savings on your energy bill in terms of energy and electric demand being saved, and longer equipment life. Commonly, on inductive loads, electricity does not travel efficiently because there are several inherent losses within the electric grid.
The National Electric Code (NEC) requires that every wire, every circuit breaker, distribution panel and transformer must be at least 125% oversized. This results in most motors being lightly loaded; therefore increasing the amount of electrical losses at the loads and throughout the electrical system. By using KVAR ECs™, energy losses are reduced on the load side of the utility transformer through the optimization of the PF of individual inductive loads. The measured overall effect on individual applications varies. Because we test the PF before and after, we are able to determine the requirement or non-requirement for a KVAR EC™, with potential customers having full knowledge of the efficiency of their electric system.
Our KVAR Distributors are bound to install KVAR ECs™ only when an estimated 6% of savings will accrue to the customer. Typical savings for residential units will vary from 6% to 10%; commercial from 6% to 17%; and industrial from 6% to 25%. We also have a long list of deployments that exceed these benchmarks. Our satisfied customers span the globe and are found in most business sectors. Customer testimonials, including billing evidence, datasets and sector-by-sector references are available upon request. Area-wide deployments of KVAR EC™ will significantly reduce demand placed on the electric grid. Utilities will also reduce both transformer and line losses. All KVAR EC™ equipped customers will also benefit from reduced power bills. For customers subjected to demand charges and PF penalties, they will be reduced or eliminated. Working in conjunction with electric utilities, the KVAR Corp. helps prepare and coordinate energy efficiency programs suited to the individual requirements of the utility and their customer base.
In North America, the KVAR Corp. is already working with its KVAR Distributors and their customers to help them take advantage of incentive programs available through utilities, power planning council, administrations and commissions; and other municipal, county, state, federal and provincial entities. The KVAR EC™ truly represents a potent electric distribution system improvement, which needs to be considered first among energy efficiency and conservation measures that have the ability to better both the electric grid and utility customers. The key to obtaining the best possible economic advantage from electric power is to get rid of wasted power by ensuring a high PF throughout the Smart Grid.
