Where do we put our Standby system and how much space is needed?
There are some minimum distances required by the National Fire Protection Association (NFPA 58). For a small system including propane storage of less then 2,000 gallons and a gas fired vaporizer, the tanks have to be located a minimum of 25 feet from the building. The tanks have to be separated a minimum of 15 feet from the vaporizer/mixer, and the vaporizer/mixer needs to also be located at least 25 feet from any buildings. This unit requires a total area of approximately 14 feet x 42 feet. Propane tanks larger than 2,000 gallons must be at least 50 feet from any buildings.

A larger system with a 30,000 gallon tank needs a total area of approximately 85 feet x 12 feet for the propane tank, and approximately 15 feet x 15 feet for the vaporizer/mixer assembly. Distance minimums will vary with state, local, and insurance codes and will also vary with the size of your system.

What does Energys USA Inc. offer that's better that the competition?
Our customers are always pleasantly surprised to see that there is a company that offers a one-stop solution to their alternate fuel needs. The following is a brief description of the major services we provide.

Cost Savings Analysis

Prior to the purchase of a standby system, Energys USA Inc. will provide you with a complete cost savings analysis. This is done by working directly with you and your utility company. A savings analysis will show your estimated savings when switching to an interruptible rate. A detailed analysis will show past, present and future savings.

In addition to reducing natural gas costs, Energys USA Inc. will do a savings analysis on current propane tow motor usage. Once a standby system is installed, the propane storage system may be used as inventory for filling propane cylinders at a greatly reduced cost. These services are no cost to our customer.

System Design and Installation

Once a savings analysis is complete, a complete survey of your natural gas burning equipment and site will be done. A system design and cost will be done in detail. All at no cost for our customers.

What is a Propane / Air standby system and how does it work?

A propane/air standby system is a backup or alternate fuel system for large users of natural gas, such as manufacturers who use gas for the production of their product by heating, melting, drying, etc. Other uses would be for schools, hospitals, hotels, dry cleaners, paint ovens, foundries, paper mills, food processors, and many more.

The system has three basic components. The first is a propane storage tank which comes in sizes ranging from single 1,000 gallon capacity tanks, up to multiple 90,000 gallon capacity tanks. We normally suggest that our clients have between one to two weeks of backup supply on-hand to cover plant needs in case of extended curtailments, or delivery problems due to weather or force majors.  Storage tanks are sized in 1, 2, 3, 6, 9, 12, 18, 30, 60 and 90,000 gallon size capacities.

The second component of the system is a vaporizer. Propane has a boiling point of minus forty-four degrees below zero. On extremely cold days the natural vaporization rate of liquid propane is insufficient to cover the needs of most users, so a vaporizer is necessary. The vaporizer indirectly heats the liquid propane at a very fast rate to transform it to a vapor state—which is needed for proper combustion. These vaporizers are sized by the gallon per hour of liquid propane it can vaporize. They range from as low as forty gallons per hour to ten thousand gallons per hour and can be manifolded together to accommodate an unlimited amount of vapor for even the largest users.

The third component of the system is the propane / air mixer. Propane has a vapor BTU content of approximately two thousand five hundred BTU’s per cubic foot, and natural gas has a BTU content of approximately one thousand BTU’s per cubic foot. Since propane’s BTU content is so much higher, it has to be diluted. To do this, the vaporized propane is run through a propane / air mixer that mixes approximately forty-seven percent air and fifty-three percent vapor propane, to derive a mixture that is compatible with natural gas. These propane air mixers are sized by the total BTU’s per hour of mixed gas it can produce. They range in size from single units of three million BTU’s per hour to in excess of five hundred million BTU’s per hour, and can also be manifolded together to produce an unlimited amount of mixed gas.

After the process of storing, vaporizing and mixing the propane, the mixed gas is then injected into the existing natural gas line downstream of the meter. It can be used in all of the equipment that natural gas is used in (without changing any burner tips) except for endothermic units with ceramic parts, and thus becomes the perfect alternate fuel.

Why should we install a Propane / Air standby system?

There are several benefits to the user of a propane / air standby system. The first is that it is a backup source of fuel in case the natural gas supply is cut off. This happens in extremely cold weather when the natural gas demand is very high and there is not an adequate amount to supply all users, either large or small. The natural gas utility companies will then curtail supply to large users, such as manufacturers that use gas to produce their product.

This enables the utility company to insure supply to homes, hospitals, schools, etc. Without an alternate fuel backup system most facilities would have to shut down production, which can be very costly. With the propane / air standby system, they would not have these costly shutdowns.

Another benefit to the user of a propane / air standby system is the ability to monitor the cost of two fuels. In most cases natural gas is more effective than propane; however, due to gas market fluctuations there are times throughout the year that propane does become a better buy. At that time the system may be utilized to produce some potentially large savings.

The third, and by far the largest benefit to the user of a propane / air standby system is the ability to receive an interruptible natural gas rate from their natural gas utility company. All natural gas companies offer two basic rates, a firm and an interruptible rate. The firm rate is the highest rate for the user. An interruptible rate is the rate offered to the user with a standby system. This rate ranges from twenty to as much as fifty percent lower than the firm rate, and is offered to the user year round. Most propane/air standby systems have a pay back, or return on investment of less than three years and some as low as five or six months.

How long does it take to install a Propane / Air standby system?

Smaller prepackaged units can be totally installed in as little as one to three days. Larger units that consist of 30,000-gallon tanks may take up to four or five weeks to install. In addition to the installation, it usually takes about 10-12 weeks for the manufacturing of the vaporizer and mixing equipment. We normally allot 12-16 weeks for the cycle:  from purchase order to installation and training to be completed.

Finance and Lease Options

The purchase of a standby system will many times not fit into current budgets, therefore making it difficult for our customer to obtain the large potential savings for an extended period of time. Energys USA Inc. has purchase options that will enable our customers to install a system at no cost. This can be done in the form of a rental or lease arrangement. All of our financing mechanisms are designed to enable the customer to purchase a system without a change in current cash flow. There is also a shared savings lease option where Energys USA Inc. will fund the entire project in return for a percentage of the savings.

Service Contracts

Because standbys are used infrequently, people tend to neglect the small preventative maintenance measures necessary to keep the system in peak operating condition. With our service contract you can be assured the system will always be ready. Under our service contract  your system will be completely tested and operated prior to the heating season. In addition to the complete service and safety check, our Service Technician will do a complete review of start-up and operating procedures with company personnel assigned to run the system, and will also answer any questions they may have.
