What is an Economizer and How Does it Improve Efficiency?

Posted by Kenny Beach on Mar 2, 2021 9:00:17 AM

In industries like commercial and industrial HVAC, there’s an understandably massive focus on innovations aimed at improving efficiency. Billions of dollars are spent every year on research and development to drive down operating costs without compromising on performance. Doing more with less is the name of the game, and included among the measures intended to do so is the economizer.

Coils' Roles in Football's Biggest Game

Posted by Super Radiator Coils on Feb 4, 2021 7:02:31 AM

As far as stages go, the big game is one of the biggest out there, and there’s a small army responsible for making sure the game goes off without a hitch. Behind that army of personnel is an even larger assemblage of vehicles, equipment, and other technology that help along the way – one of which is the heat exchanger.

Water Quality & Filtration in Liquid-Cooled Data Centers

Posted by Kenny Beach on Jan 12, 2021 9:13:57 AM

Cooling data center IT equipment using air has been the industry standard for as long as there's been a data center industry. However, advances in computing technology have pushed the limits of what air-cooled systems are able to efficiently keep cool, as the amount of power needed to operate those systems increases.

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.

Transcritical CO2 Refrigeration: Basics and Benefits

Posted by Ken Allen on Jun 23, 2020 12:18:42 PM

Around 2010, the first refrigeration systems operating on transcritical CO2 began cropping up in North American supermarkets. Since then, usage of transcritical CO2 systems has grown steadily and they’ve become viable options for places like supermarkets, food warehouses, and ice rinks, as more organizations move away from traditional HFC refrigerants. Natural refrigerant market accelerator Shecco estimates that transcritical CO2 systems grew from 140 in 2008 (all in Europe) to more than 35,000 systems worldwide today.

R-410A vs R-407C in Warmer Ambient Environments

Posted by Ken Allen on Jun 19, 2020 9:49:05 AM

There are dozens of commercially available refrigerant options on the market today, including numerous refrigerant blends, which aim to replicate the effectiveness of former workhorses like R22, the production of which was made illegal as of January of this year. Two popular examples of refrigerants developed in the last 30 years or so that are used in the HVAC industry are R-410A and R-407C. These two refrigerants are often used for similar applications, but they have some marked differences that should be understood and considered when deciding between them.

Flexible Scheduling and Reliable Delivery for OEMs

Posted by Super Radiator Coils on Jun 17, 2020 2:22:25 PM

We serve a diverse customer base at Super Radiator, one segment of which are what’s known as original equipment manufacturers (OEMs). Though we classify them together, OEMs and their respective industries all operate differently. Some customers are recurring business – they need coils every week consistently over a given timeframe – we’ve seen this with commercial HVAC or datacenter OEMs. Other customers need us to supply coils for projects that may arise infrequently over a period of years, which describes industries like transit cooling.
