How are ethylene glycol and propylene glycol different and which should I use?

Posted by Will Klick on Sep 28, 2020 3:35:57 PM

For low-temperature hydronic systems, systems in which chillers and AHUs are located outdoors, or other equipment used in low-temperature processes, some form of glycol is a critical ingredient. It works to lower the fluid’s freezing temperature, enabling lower-temperature operation and preventing freezing.

Airside fouling in heat exchangers: causes and solutions

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.

Flexible OEM scheduling from SRC: what you need, when you need it

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.

Fin enhancements for plate fin heat exchangers: purposes and tradeoffs

Posted by Super Radiator Coils on Jun 8, 2020 11:11:15 AM

In plate fin heat exchangers, the fins themselves play a critical role. They provide the extended surface area needed to achieve effective heat transfer between a gas on the finside and a fluid on the tubeside.
