PowerFurnace™ & PowerAire™ System Features


PowerFurnace™

Heat and Power - Both from One Appliance

Onsite Power Production that is independent of the traditional grid as well as efficient, cost-effective, eco-friendly, and reliable. An excellent primary power or back up power source that eliminates any loss from power outages.

PowerAire™

Cooling, Heating, and Power - All in One Appliance

Independent, onsite power production that is cost-effective, efficient, eco-friendly, and reliable. The system serves as a primary or backup energy source and eliminates power outages, peak rates, and power spikes associated with the traditional energy grid.


System Functionality

M-Trigen's micro-scaled products allow for independent micro-grid applications of cogeneration or trigeneration systems. With both systems, the engine creates heat which is utilized for water and space heating and the power generated provides electrical energy to the establishment. The PowerAire system utilizes a compressor that runs refrigerant through the facility's condenser and air handlers to function in the same manner as a traditional air conditioning unit. The systems provide continuous, reliable energy day and night without the need for any external backup batteries being required. Excess power can also be sold back to the traditional energy grid as needed.

PowerFurnace Highlights

System Highlights

M-TriGen’s PowerFurnace heating and power system increases reliability, decreases expense, and is environmentally friendly. One PowerFurnace system provides 20kW of continuous electric power or 25kW of intermittent electric power. It is designed to provide independent primary power while simultaneously capturing the heat loss from the engine, increasing the energy efficiency by using it for water and space heating. The system can also be connected to the traditional energy grid for backup power. Always on, On Demand power to handle intermittent peak and surge loads from motors and appliances.


PowerFurnace Features

PowerFurnace harnesses 40% to 60% more waste heat energy than other power generators. It is twice as efficient as a standby generator or the central power grid’s combined cycle generators. The system makes the most efficient use of fuel by producing heat and power at the point of use allowing the facility to benefit from maximum efficiency in distributed energy generation. Units are dual fuel to use either natural gas or propane as a base fuel and are easily integrated into existing or new solar energy production systems. The PowerFurnace system is ETL listed and conforms to UL, ANSI, CSA, and CGA safety standards.

Design and Installation

MicroGrid Storage provides support for the integration of PowerFurnace and PowerAire Systems into new and existing facilities.


On-Grid and Off-Grid Operation

The PowerFurance and PowerAire Systems are designed to function as a source of primary power in both on-grid and off-grid configurations. They are interactive energy management systems that complement and control Solar Photovoltaic (PV) arrays, and/or Wind Power systems through built-in inverters. Significant savings can be achieved by programming system software to Time of Use (TOU), and Tiered Electricity Pricing (TEP) models since the systems can be configured to operate as the primary source of power or to produce surge loads during high value hours of the day. This is advantageous as a method of peak load shaving for minimizing overall expense. Excess power produced by the system can be sold back to utility companies.

System Operation

How it Works

PowerFurnace and PowerAire make the most efficient use of fuel by producing heat and power and additional cooling in the case of the PowerAire at the point of use allowing the home or business owner to benefit from distributed power and maximum efficiency in energy generation. This process is typically two to three times more efficient as a centralized electrical utility grid. The result is lower energy bills.


PRODUCT SYSTEM DELIVERABLES

.
Power

POWER

  • Continuous power source – producing electricity to use or sell back to the grid
  • Provides uninterruptable power when the grid goes down
  • The engine runs only when cooling or heating is required, generating power and hot water at the same time. The battery bank remains on alert to start the engine if it is in 'off' mode when the power grid fails. The engine’s speed is automatically regulated to meet the load demand as needed.
  • Sufficient power is generated to handle peak and surge loads with priority logic for any critical electrical loads provided by a universal load management system while automatically acting as the primary power or back-up power.
  • The PowerAire™ provides uninterruptible power with battery back-up ensures absolute redundancy during any power failure for all HVAC, hot water and essential power requirements. Harmful power surges, spikes and electric noise are eliminated.
.
Cooling

COOLING *PowerAire Only

  • The natural gas / propane engine drives a compressor which cools just like an electric air conditioner but at a lower cost of energy.
  • The patented design uses its natural gas or propane fueled engine to power the onboard compressor, which provides cooling like a traditional air conditioner, only much more cost effectively. No other micro-sized system offers cooling.
.
Heat

HEATING

  • The engine creates heat, which is recovered for water and space heating.
  • Heat energy is transferred to the application (hot water heater, hydronic heat system, desiccant dehumidifier, etc.) through a thermal loop system utilizing easy-to-connect ports located on each PowerAire™ or PowerFurnace™ unit.
  • Outlet water temperature off the engine is typically 170° - 180°F.
.
Efficiency

EFFICIENCY

  • Offers the lowest operating cost of any heating / cooling systems
  • Fully programmable inverter allows for time-of-day and peak shaving, interfaces with solar or wind power, sells back to the grid and integration with multiple units

INSTALLATION READY

Delivered ready for installation, with connections to the building’s existing electrical panel, HVAC system for the PowerAire, and connections for renewable power systems. The modular design can be easily configured to match the exact requirements for any site’s specific load demand.

PRODUCT FEATURES

Remote Monitoring

Remote Monitoring

Multiple modes of operation are fully programmable and intelligently controlled through smart devices or a building automation system providing additional peace of mind and ease of operation.

Daily run time, time of day peak shaving, power interface and integration with multiple units are adjusted through the electronic control unit which is remotely addressable by certified technicians from electronic devices such as a cellphone, tablet, or computer.

Net Metering

Net Metering

Generated power can be sold to the grid together with other renewable energy systems, such as solar and wind. The ability to resell to the grid is determined by rules and regulations of the retail power service provider at the location.

Interconnected to the electric grid for back-up power in the event of service interruption, and to sell excess power back to the grid.

Renewables

Renewables

Solar and wind power easily integrates to work in conjunction with the batteries and inverter, energy management, power storage, and monitoring system, that can be configured to work side by side or together with micro-inverter systems.

Energy is stored uniquely and is directly compatible with solar panels and wind turbines to create a sustainable bridge for using renewable power sources that avoid costly and inefficient ‘net metering’.

Solo or Island Mode

Solo or Island Mode

In solo or island operation mode, configuration to generate power at any desired voltage up to 460Vac 3 phase is possible. In Single and Split Phase, up to four units can run in parallel and in Three Phase, up to twelve units can run in multi cluster configuration.


COMPONENTS
