Functions as a continuous power source, producing electricity to use or sell back to the grid. Provides power and HVAC when the electric grid fails.
The natural gas (or propane) fueled engine creates heat, which is recovered for water and space heating.
The compressor runs refrigerant through the building’s condenser and air handlers, cooling just like an electrically-driven air conditioner or heat pump.
EASY TO INSTALL
HOW DOES THE SYSTEM WORK?
Micro-sized CHP (combined heat and power) systems such as Gridiron are designed to produce power, and heat. Sometimes referred to as tri-generation, MCCHP (combined cooling, heating and power) systems add the additional element of cooling. These systems can achieve very high levels of efficiency, which provide the user with significant cost savings and reduced impact to the environment.
WHAT ARE THE BENEFITS OF GRIDIRON?
CHP is more efficient than the traditional generation of electricity and thermal energy.
CAN A GRIDIRON UNIT POWER AN ENTIRE BUSINESS OR HOME?
That would depend on the size of the structure and the loads that you wish to power. In a 2,000 sq. ft. building, for example, the system can be configured to provide all of the power and heating that is necessary. Depending upon the configuration, one Gridiron unit can provide 6kW to 24kW of electric power, which should be sufficient to power all of the loads of a conventional small business or home. For a standard CHP (combined heat and power) application, Gridiron’s PowerPlant H24 system is best for maximizing the use of heat while producing power that can, in turn, run a separate electrically driven air compressor for refrigeration if needed as a secondary appliance.
MCCHP systems, such as M-Gridiron’s PowerPlant HA65, combine to produce cooling as well as heat and power. Sometimes referred to as trigeneration, combined cooling, heat and power systems achieve a secondary level of efficiency in optimizing the production and usage of cool air through the use of conventional HVAC compressor driven by the engine drive train. Trigeneration systems are effective for buildings as well as some industrial processes requiring continuous uses for both heating and cooling.
WILL THIS DEVICE REPLACE MY ELECTRICAL PROVIDER?
That would depend on the size of the building, the loads that you wish to power, and your desire to be off grid. In many cases it becomes the primary source of power with the grid as backup.
WHAT, SPECIFICALLY, DIFFERENTIATES THIS FROM STANDARD GENERIC OR OTHER NATURAL GAS GENERATORS, OTHER THAN CAPTURING THE EXHAUST HEAT?
eneric generators are only designed for standby duty(typically 200 hrs/year), unlike Gridiron that is designed for continuous duty. Continuous duty generators are designed to last under severe conditions, whereas standby units are designed to provide power for short periods of time. Generic generators have very low efficiency ratings and therefore burn 2 to 3 times more fuel than the Gridiron. Standby generators are also sized to provide loads to all appliances cumulatively as opposed to meeting real consumption patterns. This often results in the over-sizing of the unit that also affects the efficiency of the system negatively. The Gridiron is a heavy duty system designed to run continuously but will throttle faster or slower to meet the load demand required.
HOW LOUD IS THE SYSTEM?
The Gridiron system is designed not to exceed the noise level of conventional outdoor HVAC condensers (68 db).
CAN I DRIVE MY CURRENT HVAC SYSTEM WITH THE GRIDIRON SYSTEM?
Gridiron’s PowerPlant HA65 is often compatible with some of the components already in place in locations with HVAC systems. A site survey is required to determine what components may be reused. Please consult our design team if you have a special need that requires the integration of the Gridiron with an existing HVAC system.
CAN GRIDIRON POWER MY AIR CONDITIONING DURING A POWER OUTAGE IF I DON'T INSTALL THE POWERPLANT HA65 SYSTEM?
Gridiron’s PowerPlant H24 system operates to provide electrical power that can handle most standard HVAC systems.
WHAT IS THE MAIN DIFFERENCE BETWEEN THE POWERPLANT H24 AND THE POWERPLANT HA65 SYSTEMS?
The PowerPlant H24 provides electrical power and heat for reuse, whereas the PowerPlant HA65 additionally provides air conditioning.
WHAT IS THE IMPACT OF DEHUMIDIFYING THE AIR IN MY HOME USING THIS SYSTEM ON MY AC POWER USAGE?
With independent control of humidity, the temperature of the space can be raised (2 to 3 degrees F) without sacrificing comfort, resulting in significant energy savings. In addition, controlling the space humidity in the 45-50% RH range, improves indoor air quality by preventing the growth of mold, mildew and, in particular, dust mites, which can trigger many allergies.
WHAT IF I INCORPORATE IT INTO MY SOLAR HOT WATER HEATING SYSTEM?
Gridiron’s PowerPlant products are complimentary to most solar hot water systems. The system was designed to provide an independent hot water circuit that can be integrated to existing solar hot water, boiler systems, hot water tanks, water to air radiators, etc.
HOW WILL THIS WORK IF I HAVE A SOLAR ELECTRIC SYSTEM WITH ENPHASE MICRO-INVERTERS, AND I DON'T WANT TO RE-STRING THE SYSTEM?
The PowerPlant HA65 system is designed to integrate and control renewables like solar or wind power through its built-in inverter. However, Gridiron can be designed to work side by side or together with micro-inverter systems. Our design team will be able to suggest configurations once you provide your existing system drawings. We can also do a site survey and a proposed system design drawing.
IF I AM BUILDING A NEW HOME AND MY ARCHITECT OR BUILDER HAS NO KNOWLEDGE OF HOW TO INTEGRATE THIS EQUIPMENT INTO THE DESIGN, CAN YOU PROVIDE DESIGN SERVICES AND IF SO, WHAT IS THE PROCESS AND WHAT ARE THE FEES?
Gridiron or its dealers provide design and integration support services for the integration of the system into both new and existing homes and commercial buildings. For new applications we would review the project plans and work with either the architect or HVAC subcontractor.
WHAT SIZE SWIMMING POOL CAN BE HEATED?
The system can be configured to provide as much as 6 - 12 tons of heat (70,000–140,000 BTU's). The heating impact depends on the size, depth of the pool, and the amount of time the system is operational each day.
WHAT SIZE WATER TANK CAN BE HEATED?
The system can be configured to provide as much as 6 – 12 tons of heat. In most cases the gas needs for water heating can be eliminated with the use for the systems waste heat.
CAN THE DAILY RUN TIME BE AUTOMATICALLY AND MANUALLY ADJUSTED THROUGH THE ELECTRONIC CONTROL UNIT (ECU) ON THE GRIDIRON?
The amount of daily run time can be automatically or manually adjusted through the electronic control unit (ECU) on the Gridiron. The systems are remotely addressable from electronic devices such as a cellphone, IPad or computer.
WHAT IS THE LARGEST GRIDIRON SYSTEM AVAILABLE?
Gridiron currently builds units that can provide 20 to 24 kW of AC power. Multiple units can be tied together to provide enough power to accommodate most commercial and light industrial facility needs.
WHAT COLORS DO THEY COME IN?
HOW LONG HAS GRIDIRON BEEN IN BUSINESS?
Gridiron and its predecessor M-TriGen, Inc. has been in business since 2011 and has been conducting R&D since that time.
HAS THE SYSTEM BEEN TESTED BY ANY SAFETY STANDARDS OR TO SOME SPECIFICATIONS?
Gridiron provides the only regulatory-approved micro-combined cooling, heating and power system in the world. Its products are UL, CUL, ETL listed, based on recognized safety standards and manufacturing processes. UL and ETL regularly audit the factory and its processes to ensure continued compliance with safety standards.
