I Need a Replacement Commercial HVAC Coil. Where Do I Start?

Posted by Gregg Fletcher on Oct 13, 2021 8:26:29 AM

As a custom coil manufacturer, we often speak with facilities managers and maintenance professionals about coil replacements, upgrades, and retrofits. These jobs often require us to design a coil for an existing space, which can be tricky if you're not sure what to look for. For this post we’ll explain that process, including:

  • Common size-in-place scenarios for commercial HVAC coils
  • Some best practices when replacing a coil
  • Other important coil replacement considerations

This is the first in a series of articles about battery power and its adjacent industries and processes. Check out our other post, "Application Spotlight: Solvent Recovery and Battery Liners."

Today, energy comes from a wide range of sources. The share of that collective power that comes from renewable energy sources continues to grow. In fact, in 2019, it was estimated that just under 20% of electricity generated at utility-scale electricity generation facilities in the United States was from renewable energy sources.[1]

What is a Refrigerant Distributor and What Does it Do?

Posted by Ken Allen on Oct 5, 2020 12:17:44 PM

In a refrigeration circuit, the evaporator coil plays a critical role. Part of its responsibility is creating the controlled pressure drop necessary for the refrigerant to change phase, the bulk of which occurs via the system’s metering device, such as a thermostatic expansion valve (TXV).

Causes & Solutions to Airside Coil Fouling

Posted by Louis Rogerson on Jul 13, 2020 6:02:25 PM

Fin tube heat exchangers are subject to fouling, which takes place as long as there is an airflow or waterflow in the unit. Defined as thermal resistance due to the accumulation of contaminants on heat transfer surfaces, fouling negatively affects heat exchanger efficiency, longevity, and increases system operating costs.
