Home backup solutions
Arex delivers generator sets for different applications. Our knowledge and expertise in emergency and continuous power is built on years of co-operation with leading diesel engine and generator suppliers Perkins, FG Wilson (industrial applications), Kohler and Lombardini (Marine generators) and many more.
A permanently installed home backup generator by Arex Power Systems protects your home automatically. It runs on natural gas or liquid propane (LP) fuel, and sits outside just like a central air conditioning unit. A home backup generator delivers power directly to your home’s electrical system, backing up your entire home or just the most essential items.
Don't worry about having to be there to start and stop your home backup generator. Because it does that automatically. Whether you're home or away.
Refueling Not Necessary
Your home backup generator runs on your existing natural gas or LP fuel supply. Save the gas cans for your other outdoor power equipment.
Power Directly to Your Home
You'll never have to run an extension cord through a window or door again. Your home backup generator safely delivers power right to your home's electrical panel.
24/7/365 Customer Support
Power outages aren't a 9-to-5 thing. That's why we're standing by all day every day from our headquarters to answer any questions you might have.
Business backup solutions
We know you are about to make a big invesment. Here's what you need to know to make an informed buying decision.
How Do I Choose the Right Size Standby Generator for My Business?
The best way is to work with one of our dealers. They are special trained to determine your backup power requirements. They'll help you select the right standby power system, and provide you with a quote for the generator and installation.
What's the Risk if I Don't Have Backup Power?
In addition to the business you will lose if you aren't open, a power outage could cause your refrigerated and frozen inventory to spoil. To find out exactly what you stand to lose, take our free risk assessment.
What Fuel Type Should I Choose?
Our generators are available in diesel, natural gas, and liquid propane (LP) fueled models. Each offers its own unique benefits, and your dealer can help you decide which one is best for you.
What if I Have More Than One Location?
We can help you select the right standby power system for each of your locations, arrange for installation on your schedule, and even schedule routine maintenance programs.
CHP Cogeneration Systems (Combined Heat & Power)
In the conventional systems, the generator set produces only electrical energy and can work with efficiency between 32- 42% that depends on operation type like as lean burn or stoichometric. All of the heat energy transferred to the environment and efficiency is limited with engine mechanical and generator electrical efficiency.
Cogeneration (CHP - combined heat & power) is the producing of electrical & heat energy together from a single source and to get a conclusion of high efficiency and low emissions. Heat energy can be utilized as a hot water, steam, hot oil or chilled water with a special equipment to increase the system efficiency.
CHP operation, opposite of conventional generator set system, allows to use the heat energy from jacket, exhaust and/or intercooler system of engines. And to reach the highest efficiencies between 85-95% according to the engine property. It means that consumed natural gas for generator set (or biogas like digester, landfill and sewage) will be evaluated in 85-90%. Short delivery time and refunds of investment, long runtime period and low emissions for cleaner environment are popular advantages of the CHP systems.
The most important point is to decide choosing the right generator set. In applications without network, the right selections are the stoichometric engines with the reason of high step loads with high heat power (electrical efficiency %30-37).In power export applications the right selection is the lean burn engines with the reason of fixed load with high efficiency (%40-42).
Trigeneration system is a further step of CHP system to get refrigeration. It is formed with adding of ABS chiller,cooling tower, heat exchanger, pumps and 3-way valve on CHP system. Heated water(around 95’C) will be proceed in this additional system to give cooled water(up to 7’C) to customer side. According to requests, trigeneration systems are suitable for using in all seasons, even in winter.
