New Champion LX Series packaged units heat and cool residential and light commercial buildings. 

The Pelican™ case housing provides a watertight, crushproof, dust-proof enclosure with heavy-duty deflector ribs for extra protection from shocks and impacts.

This handheld device displays CO, CO₂, air temperature, rh, dew point, and wet bulb temperature measurements.

This product provides field-selectable current or voltage output that is proportional to the CO concentration of an area.

This product now features mercury-free temperature elements as an option in any 8- or 12-inch case configuration, in ranges between minus 30˚ and 600˚F.

Designed for HVAC and refrigeration professionals to view electrical and temperature readings, this product logs data remotely using the ExView® W-Series app on smartphones and tablets via Bluetooth.

Is reducing a facility's energy consumption by over 130,000 kWh annually through HVAC optimization possible?

With the election of Donald Trump to President of the United States, the HVAC industry is wondering how this will affect the Inflation Reduction Act incentives.

Low public awareness of incentives that can subsidize residential HVAC purchases means contractors have the opportunity to educate and position themselves as trusted advisors, marketing experts say.

Since more companies are putting a focus on ESG principles, the HVAC industry is positioned to turn those goals, into a reality.

When it comes to comfort, not much beats zoning. In fact, many industry experts tout that once homeowners have experienced the comfort zoning has to offer, they will never own another house without it.

This product replaces standard supply registers with sensor-equipped registers that automatically measure each room’s dynamic conditions and optimally balance air distribution throughout the home.

This climate control solution ensures balanced, room-by-room comfort throughout the home.

This enables users to control their hydronic radiant panel, baseboard, or radiator to heat to the exact temperature and from wherever they may be.

With “heat pump” and “incentives” almost being synonymous at this point, contractors need to understand the basics to ensure customers are receiving the benefits.

BlocPower, a climate technology company focused on greening America's buildings, announced a fundraising round of $150 million, including more than $24 million of Series B corporate equity led by VoLo Earth Ventures and $130 million of debt financing led by Goldman Sachs.

In this episode we discuss with Randy Shoup, Distinguished Architect at eBay, about architectural pinciples and patterns used for building the highly scalable eBay infrastructure. The discussion is structured into four main ideas: partition everything, use asynchrony everywhere, automate everything, and design the system keeping in mind that everything fails at some point in a large distributed system.
