Every so often, we like to take a detailed look at the applications for which our products are used. This installment will focus on solvent recovery applications during the production of battery products. In this post we’ll answer the questions:

• What is solvent recovery?
• How is solvent recovery used in battery liner production?
• What role does heat transfer play in the process?

This is the second of a series of articles about battery power and its adjacent industries and processes. Check out the first post in the series - “Battery Storage Facility Cooling System Design.”

We’re super excited to announce that we’ve validated the performance ratings for R-449A and R-448A condensers in Enterprise, our coil selection software. We believe the condenser coil performance model we’ve developed is the most comprehensive and accurate of its kinds in the industry.

We wanted to use this post to briefly explain our testing methodology to our users. We’ll also touch on why performance modeling for these refrigerants has been challenging in the past, and how we plan to improve our model over time.

Hydronics systems? Football? While you may not hear those terms in the same breath every day, there’s actually a mind-blowing amount of design and engineering that help keep football field surfaces playable through the cold winter months.

First, some context

With this year’s big game being played in Tampa Bay, frozen ground won’t play a factor, but January's NFC championship game took place at the site of probably the most famous instance of frozen turf in history - historic Lambeau Field.

There are a number of industrial processes that require extremely cold temperatures – sometimes as cold as -150°F. For the equipment used in such applications, those low temperatures pose some unique challenges. In this post, we’ll detail some of the temperatures involved and outline some things to consider with regard to heat exchanger design and materials for low-temp applications. 

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. 

When designing a heat exchanger, an engineer should not only consider thermal performance, but also external influences that can negatively impact thermal performance, such as fouling.

Gas-tungsten arc welding (GTAW), or more commonly, Tungsten Inert Gas welding (TIG), is a method of arc welding named for the non-consumable tungsten electrode used during the process. TIG welding isn’t the best option in some industries, but as coil manufacturers, it makes sense for us.

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).

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.

There are terrific braze joints, awful braze joints, and everything in between. Today, we’ll examine one type of defect that can have devastating effects on joint integrity – flux entrapment.
