316 Stainless Steel Products- Always in Stock

Metallurgically speaking, stainless steel is a steel alloy with the highest percentage contents of iron, chromium and nickel, with a minimum of 10.5% chromium content by mass, and a maximum of 1.2% of carbon by mass.

Stainless steels are widely regarded for the corrosion resistance that they exhibit. As the chromium content is raised, the corrosion resistance increases as well. The addition of molybdenum also increases the corrosion resistance to reducing acids and against pitting attacks in chloride solutions. By varying the chromium and molybdenum content, different grades of stainless steel are produced with each suited for varying environments. Due to the resistance to corrosion and staining, stainless steel is ideal material for many applications, especially in the food, pharmaceutical, and chemical industries.

The 300 series stainless steels are considered chromium-nickel alloys and is the largest group and most commonly used. Of the different compositions within the 300 series family, Type 304 stainless is the most widely used followed by Type 316, which has 2% molybdenum added to provide greater resistance to acids and to localized corrosion caused by chloride ions.

Table below shows the nominal composition by mass content for 316 stainless steel

Because 316 stainless steel provides a high level of corrosion resistance, resists pitting, and has good strength properties, EXAIR manufactures many of its products from 316 stainless steel material so that they can be used in the harshest of environments.

Of the EXAIR products these are available off the shelf in 316 stainless steel- Super Air Knife, certain sizes of Adjustable Air Amplifiers, numerous Air Nozzles, Line Vacs including the Sanitary Flanged style, NEMA Type 4X and Hazardous Location Cabinet Coolers. If you need one of our other products such as the Super Air Wipes or Vortex Tubes made in 316 stainless steel, just let us know. Of course we also have them made from Type 303 stainless steel, in stock and ready for shipment (and aluminum, too!)

Cabinet Cooler NEMA Ratings Explained

CC_Actionshot

Temperatures are heating up across the US, when this happens it can wreak havoc on the sensitive electronics in your facility.  If you’re a follower of the EXAIR Blog, you’ve noticed that we’ve spent a great deal of time recently discussing the Cabinet Coolers. From a description of how they work, specific applications, as well as how to determine what size you’ll need, we’ve covered quite a range of topics. Equally important, though, is the NEMA rating of the Cabinet Cooler. I’d like to take a moment to discuss the different NEMA ratings for the Cabinet Coolers that EXAIR has to offer and where each should fit.

NEMA 12 – The NEMA 12 rating is for enclosures that are indoor and provide a degree of protection to personnel against access to hazardous parts as well as prevent any materials from entering the enclosure such as dust, debris, or moisture from light splashing. This standard duty style of Cabinet Cooler is best served indoors on the shop floor where there aren’t any wash-down areas or excessive moisture.

NEMA 4 – A NEMA 4 rated cabinet cooler is designed for either indoor or outdoor use. It, too, provides protection to personnel against access to hazardous parts and prevents dust, dirt, or debris from entering the cabinet. In addition to providing the same levels of protection as the NEMA 12, the NEMA 4 rating also means that the equipment will be protected from water such as rain, sleet, snow, splashing water, and even hose directed water.

NEMA 4X – The NEMA 4X carries the same levels of protection as the NEMA 4, but also adds an additional level of protection against corrosion. EXAIR’s NEMA 4X Cabinet Coolers are constructed of either 303 or 316 Stainless Steel.

EXAIR’s Cabinet Coolers are available from stock with cooling capacities ranging from 550 Btu/hr – 5,600 Btu/hr. With a variety of different materials and NEMA ratings, EXAIR has the right Cabinet Cooler ready to ship today to prevent your sensitive electronics from shutting down. Don’t let yourself get frustrated dealing with heat-related issues, get a maintenance-free Cabinet Cooler installed ASAP!

EXAIR’s Cabinet Coolers Solve Your Overheating Problems

We here at EXAIR always know when summer is approaching, as phone calls and orders for the Cabinet Cooler Systems start to kick into high gear.  After those first few hot days in late spring, it is common for panels and electrical enclosures to overheat due to faulty air conditioning units, fans that are not working, or lack of a cooling system in general.

Time for us to sharpen our pencils and be ready to help! Our Cabinet Coolers are in stock and ready to solve your overheating problems with same day shipping on orders we receive by 3pm. If you need assistance choosing your Cabinet Cooler Solution, Contact an Application Engineer today!

The Cabinet Cooler System is a low cost, reliable way to cool and purge electronic control panels.  We recently hosted a Webinar on the systems, and it is available for review (click picture below)  webinar-on-demand

EXAIR Cabinet Coolers incorporate the vortex tube technology to produce cold air from compressed air, all with no moving parts.

Below shows the basics of how the Cabinet Cooler is able to provide cooling to an enclosure.  Compressed air enters the vortex tube based system, and (2) streams of air are created, one hot and one cold. The hot air is muffled and exhausted through the vortex tube exhaust.  The cold air is discharged into the cabinet through the Cold Air Distribution Kit and routed throughout the enclosure. The cold air absorbs heat from the cabinet, and the hotter air rises to the top of the cabinet where it exits to atmosphere under a slight pressure. Only the cool, clean, dry air enters the cabinet – no dirty, hot humid outside air is ever allowed into the cabinet!

How the EXAIR Cabinet Cooler System Works

EXAIR offers Cabinet Cooler Systems for cabinets and enclosures to maintain a NEMA rating of NEMA 12 (dust tight, oil-tight), NEMA 4 (dust tight, oil-tight, splash resistant, indoor/outdoor service) and NEMA 4X (same as NEMA 4, but constructed of stainless steel for food service and corrosive environments.

Cabinet Cooler Systems can be configured to run in a Continuous Operation or with Thermostat control. Thermostat control is the most efficient way to operate a Cabinet Cooler.  They save air by activating the cooler only when the internal temperature reaches the preset level, and are the best option when fluctuating heat loads are caused by environmental or seasonal changes. The thermostat is preset at 95°F (35°C) and is easily adjusted.

Another option is the ETC Electronic Temperature Control, a digital temperature control unit for precise setting and monitoring of enclosure conditions. An LED readout displays the internal temperature, and the use of quick response thermocouple provides real time, accurate measurements. The controller has easy to use buttons to raise or lower the desired cabinet temperature set-point.

Other Special Cabinet Cooler considerations are:

  • High Temperature –  for ambient temperatures of 125°F to 200 °F – for use near furnaces, ovens, etc.
  • Non-Hazardous Purge – ideal for dirty areas where contaminants might normally pass through small holes or conduits. A small amount of air (1 SCFM) is passed through the cooler when the solenoid is in the closed position, providing a slight positive pressure within the cabinet.
  • Type 316 Stainless Steel – suitable for food service, pharmaceutical, and harsh and corrosive environments.

Expand Flexibility of Cabinet Coolers with Side Mount Kits

Last week I wrote about the Thermostat Options for Smart Cooling utilizing the EXAIR Cabinet Cooler Systems.  You can see read that blog post here.  Today we will touch base on the Side Mount Kits as an option to expand the flexibility for the installation and operation.

Sometimes there isn’t room above an electrical panel to fit the Cabinet Cooler, even though it takes just 5″ to 7.25″ of space above. In these cases, the Side Mount Kit is available to handle any of the Cabinet Cooler sizes and NEMA ratings. EXAIR offers (6) models of Side Mount Kits –

  • Model 4909 – For NEMA 12 Cabinet Coolers up to 550 BTU.hr (139 Kcal/hr), Aluminum construction
  • Model 4910 – For NEMA 12 Cabinet Coolers , 650 BTU//hr (165 Kcal/hr) and higher, Aluminum construction
  • Model 4906 – For NEMA 4 and 4X Cabinet Coolers up to 550 BTU/hr (139 Kcal/hr), Type 303 Stainless Steel
  • Model 4907 – For NEMA 4 and 4X Cabinet Coolers, 650 BTU/hr (165 Kcal/hr) and higher, Type 303 Stainless Steel

The NEMA 4 and 4X Cabinet Coolers must be mounted vertically for the unit to properly resist the ingress of liquids and maintain the integrity of the cabinet NEMA rating.

The Side Mount Kits install into a standard electrical knockout (1-1/2 NPS) for easy installation.

If you have any questions about the Side Mount Kits, Cabinet Coolers and/or Thermostat Options or any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.
