Hybrid-drive combines power sources
UNITED STATES BASED clean energy com- pany Tecogen Inc. launched its smart Tecochill Hybrid-Drive Air-Cooled chiller last month.
The Hybrid-Drive chiller seamlessly com- bines two power sources, economical natural gas and electric power from the grid, offering customers up to 50 per cent lower operating costs compared to alternative chillers, as well as dual-power-source resiliency.
When the Hybrid-Drive is powered by the chiller’s integral natural gas engine, it produces chilled water for air-conditioning plus free engine heat that is recovered to produce usable hot water.
Competing solutions are less efficient, have a higher greenhouse gas footprint, have a higher energy operating cost, and require a separate boiler to produce hot water.
The Hybrid-Drive can track inputs from the electric power grid to enable customers to

optimise economic savings and/or greenhouse gas reductions.
Marginal grid power generation in the United States is currently predominantly fossil fuel- based, particularly during peak demand peri- ods, so customers able to utilise both the chilled water and hot water generated by the chiller will benefit from both the lowest operating cost and the lowest greenhouse gas footprint.
The Hybrid-Drive can maximise greenhouse gas reductions by using power from the electric grid when the grid incrementally is powered by renewable energy and can switch to engine power when the grid is generating higher green- house gas emissions.
In addition, when grid power is more expen- sive during periods of high demand, the Hybrid- Drive can switch to operating on engine power, and then switch back to operating on the grid if prices become lower, enabling customers to optimise operations as electric grid costs and greenhouse gas emissions fluctuate.
The Hybrid-Drive can also rely on engine power in the event of grid power outages, pro- viding cooling for critical process applications when the electric grid is unavailable. The Hybrid-Drive is expected to be an excellent fit for applications such as controlled environment agriculture (CEA), healthcare, education, chiller rental, and industrial process cooling.

EZ Duct has been made for contractors
L3R AIR PRODUCTS has launched EZ Duct which is designed to replace over 100 different types of sheet metal boxes and wyes used in a traditional HVAC system.
Offering a seamless airtight box and the ability to accept 4" ducts through 8" ducts, the EZ Duct allows users to save both time and money with a variety of features.
With its virtually indestructible design, the EZ Duct cuts down the need for an inventory of wyes by more than 80 per cent. Its unique functionality was made with the contractor in mind to create an exact application that has been lacking in the field previously.
Co-founder and CEO of EZ Duct, Larry Eversole, said after many years of
owning an air conditioning company, he knew there was a need for a universal product that would replace the many sheet metal boxes and wyes sizes.
L3R Air Products president Robert Windt said its great to finally share the EZ Duct with the HVAC industry.
“It has been transformed from a sketch on paper to a fully functioning product,” he said.
With its minimal need for tools, the EZ Duct can be installed with a simple utility or pocket knife and virtually no screws.
All EZ Duct boxes also include a com- plete flange and just one EZ Duct can replace over 30 sizes of entry points found on a more typical HVAC setup.
L3R Air Products has offices around the globe.
