Cabinet Coolers Material Selection Focus: 316 Stainless Steel

Industrial environments call for equipment to be constructed of many different materials in order to stand the test of time and to meet standards set by governing agencies. Within certain environments, 316 stainless steel rules the world and there is due cause for it. In given areas, there may be chemical incompatibilities, temperature limits, or even material incompatibilities between parts within a process and the process itself.  This is why the EXAIR Cabinet Cooler Systems are available in 316 stainless steel.

The NEMA Type 4X Cabinet Cooler Systems are standard in 303 stainless steel while 316 stainless steel is also available from stock and can meet or exceed the standards set forth by NEMA Type 4X environments to stand the test of time whether it be chemical/caustic washdowns that generate the need, product material compatibility, or due to being outside.  These systems are offered in both thermostatically controlled with choice of 120 VAC, 230 VAC, or 24 VDC solenoid valve or continuous operation and can all ship same-day on orders received by 3 PM ET for domestic orders.

We also offer Hazardous Location NEMA Type 4X Cabinet Cooler Systems in both 303 and 316 stainless steel to cover even more stringent classified areas that demand UL Classified certifications.   These meet certifications for Class I Div 1, Groups A, B, C and D, Class II Div 1, Groups E, F and G, as well as all Class III environments.  These systems are also offered in the same thermostat control voltages as well as a continuous operation.

The point is, if you have an overheating control panel or electrical panel, we will have a solution that can keep your production running, all you have to do is contact us.

NEMA What?

With the Summer heat beating down most of the nation this week and the calls for Cabinet Cooler Systems are like the temperatures, through the roof, I thought it would be good to discuss the different NEMA types.  EXAIR offers our Cabinet Cooler Systems in three different NEMA types, 12, 4, and 4X.  Below is a description of what each is suitable for.

NEMA Type 12

NEMA Type 12 enclosures are general purpose use enclosures.  These are designed for indoor use and are designed to provide protection against dust, falling dirt, and dripping non corrosive liquids.  This is generally what the enclosures on most metal-cutting machines are rated.  These enclosures are only available for non-hazardous areas.  An enclosure with a NEMA Type 12 may or may not have a gasket seal on the door and on all electrical knockouts.  The EXAIR NEMA Type 12 Cabinet Cooler Systems for these units are available in cooling capacities from 550 – 5600 BTU/hr. along with continuous operation or thermostat control, non-hazardous purge, high temperature operation, and with the EXAIR Electronic Temperature Control.

NEMA Type 4

NEMA Type 4 enclosures are designed to be watertight / weatherproof.  These enclosures are not corrosion resistant but they are able to protect the inside of the enclosure from  a minimum of 65 GPM from a 1″ nozzle delivered from a distance of 10′ for 5 minutes.  These are found in wash down areas where Stainless Steel is not needed along with outside where corrosion is not a concern.  These units can be used on a NEMA Type 12 enclosure for added protection against oil or dirt in the air.  The EXAIR NEMA Type 4 Cabinet Cooler Systems are available in cooling capacities from 550 – 5600 BTU/hr. along with continuous operation or thermostat control, non-hazardous purge, high temperature operation, and with the EXAIR Electronic Temperature Control.

NEMA Type 4X

NEMA Type 4X enclosures are designed with the same specifications as a NEMA Type 4 enclosure with the addition of corrosion resistance.   This means the enclosure must be sealed against wash down and be resistant to corrosion.  The corrosion can come from a chemical or environmental conditions such as a food process wash down or outdoors near the ocean such as on an oil rig or ship dock.  The EXAIR NEMA Type 4X Cabinet Cooler Systems are available in cooling capacities from 550 – 5600 BTU/hr. along with continuous operation or thermostat control, non-hazardous purge, high temperature operation, and 316 stainless steel.

If you have a questions about which EXAIR Cabinet Cooler System is the best fit for your enclosure or you need help sizing the system, feel free to give us a call.  You can also find our Cabinet Cooler Sizing Guide here on the website.
