Cabinet Coolers Keep Enclosures Free of Dirt and Dust…and Cool

One of the main focuses for Cabinet Cooler Systems is to cool electrical enclosures that are overheating due to inadequate cooling, failing air conditioners, or heat exchangers that are not performing due to high ambient conditions.  Another focus is the fact that the Cabinet Cooler Systems don’t require refrigerant based coolants, or fans that can move dirty ambient air into the cabinet. This is the portion I would like to focus on today.

If there are vents on the enclosure then these are sometimes covered with a filter media that is an easily forgotten maintenance item –  sometimes they are even removed.  This is an issue as it starts to allow the contaminants from the surrounding area to begin to enter the inside of an enclosure.  In case you have never seen a circuit board that is covered in oil mist and metal chips, it is terrifying to see a maintenance person that is trying to troubleshoot the machine for failures.  Not only does this present a fire hazard but it also presents the internals of the panel with a strong probability of failure.

Another item I have personally seen fail in the field are small fans mounted within enclosure vents to help circulate air through the enclosure.  This is a great idea if the ambient environment is climate controlled and has no dirt or debris in the air.   Even in a facility that is climate controlled there is still potential for airborne debris, dust, and contaminants to enter the cabinets. These are merely accelerated into the cabinet by the fan and distributed throughout the entire enclosure instead of just coming in and covering the area just inside of the vent.

The solution to all the problems above which can easily save thousands of dollars worth of damaged circuit boards or drives is an EXAIR Cabinet Cooler System.  The Cabinet Coolers will all provide a slight positive air flow within the enclosure and will help to keep those external ambient conditions out of the cabinet and away from valuable electronics.  Even with our thermostatically controlled systems (which turn on and off as needed to maintain internal temperature AND save air) we offer aNon-Hazardous Purge option which will permit a 1 SCFM flow of air through the Cabinet Cooler to always keep a slight positive pressure within the enclosure. When the cabinet needs to be cooled, it will open the solenoid valve and provide the full rate of cooling from the Cabinet Cooler System.  TheNon-Hazardous Purge function is available for all three NEMA types of Cabinet Cooler Systems, 12, 4, and 4X.

What Is The Digital Sound Level Meter?

EXAIR’s new Digital Sound Level Meter is an easy to use instrument that can measure and monitor the sound level pressure in a wide variety of industrial environments. The source of loud noises can be quickly identified and isolated so corrective measure can be taken to reduce or eliminate the problem. For compressed aire noise, it is often as simple as replacing the existing inefficient blowoffs with EXAIR's engineered compressed aire products such as the Super Air Knife, Super Air Amplifier or Super Air Nozzles. In many cases, the EXAIR products can reduce noise levels by 10dBA which is perceived as cutting the sound volume in half.

Why The Digital Sound Level Meter?

Each Digital Sound Level Meter comes complete with removable wind screen, battery, and a protective case.

Hearing loss induced by high noise in the workplace is a common problem. Exposure to high noise levels for an extended period of time can lead to permanent hearing loss for workers not wearing proper hearing protection.The Digital Sound Level Meter can help employers protect workers by monitoring noise levels so they don't exceed the limits shown in OSHA Standard 29 CFR – 1910.95(a). Failure to comply can result in hefty fines.

Accurate and responsive, the Digital Sound Level Meter measures the decibels of the sound and displays the reading on the large LCD display that has a backlight button for easier viewing. An "F/S" response time button provides a choice of slow response measurements for comparatively stable noise measurement or fast for varying noise. The “Max Hold” setting will measure the maximum noise level of sounds and update continuously if a louder sound is detected. Certification of accuracy and calibration traceable to NIST (National Institute of Standards and Technology) is included.

The Chip Trapper

The new Chip Trapper (patent pending) offers a fast, easy way to clean chips, swarf and shavings out of used coolants and other liquids. The Chip Trapper vacuums the coolant or liquid that is filled with debris and traps all the solids in a reusable filter bag. Only the liquid pumps back out. It is ideal for use on machines with sumps, parts washers, tanks and storage containers of contaminated liquids.

The Chip Trapper uses EXAIR's compressed air powered Reversible Drum Vac (included) that can fill or empty a 55 gallon drum in less than two minutes. Simply set the Reversible Drum Vac pump and directional flow control valve on top of the drum to "fill" for it to quickly vacuum the liquid with solids. Once the sump, pit or tank is empty, set the pump and directional valve to "empty" for it to pump out clean coolant/liquid. All the chips and other solids are trapped inside the reusable filter bag of the Chip Trapper.

	Chip Trapper Filter the chips out of your used coolant and cutting oils! Vacuums in the liquid with solids,pumps out only the liquid! A sudden lack of coolant flow in a machining operation will likely damage the part and expensive tooling. Machine tools commonly discharge some chips and shavings into the coolant sump. As the chips accumulate and mound up, the coolant flow used to flood the part and tooling becomes restricted. Some high pressure coolant systems sound an audible alarm and abruptly shut down the machine when low coolant flow occurs. This results in downtime to fix the problem and clear the alarm. That isn't the case with standard machines where immediate damage can occur if the operator fails to spot the lack of coolant. Regular cleaning of the coolant sump with the Chip Trapper can quickly eliminate this very costly problem.

Air Nozzle

EXAIR offers a complete selection of air nozzles suited to a wide range of blowoff, cooling and drying applications. These air nozzles have been engineered to provide a strong blast of airflow while minimizing air consumption and noise levels. They are available in many configurations and materials to suit the requirements of your application.

 EXAIR's standard force air nozzles deliver up to 22 ounces (624 grams) of force, making them suitable for most blowoff, drying and cooling applications. The air nozzles use a small amount of compressed air to entrain large volumes of surrounding room air. The award winning Super Air Nozzles have been engineered to provide the best performance. They are extremely efficient, producing a high thrust, concentrated stream of high velocity airflow with low sound levels and air consumption. The compressed air is ejected through holes located in the recessed grooves that cannot be blocked or dead ended.Click a product category to find out more!

 Ultrasonic Leak Detector

The Ultrasonic Leak Detector (ULD) is a superior instrument with high quality that can locate costly leaks in a compressed air system.The Ultrasonic Leak Detector is compact, lightweight & designed for one hand operation. Using the Ultrasonic Leak Detector a person need only aim it in the direction of a suspected leak. The LED display will light & an audible tone can be heard with the use of the headphones, when a leak is detected. At distances up to 20’ (6.1m) away the testing of various unions, pipes, valves & fittings can be done quickly & effectively.

Why the Ultrasonic Leak Detector?

ULD detects the ultrasonic noise created by pressure or vacuum leaks of any gas, regardless of type: CFC's, HFC's, Nitrogen, CO2, Steam, etc.By using a technique called “heterodyning” it translates the ultrasound to a lower frequency which our ears can interpret.

This detection method often use a microphone technology; which detect outdoor leaks by sensing the distinct high frequency ultrasound emitted by all high pressure gas leaks, meaning that the gas does not have to reach the sensor – just the sound of the gas leak. Plants easily waste up to 30% of the compressor output through leaks that go undetected .The overall operating costs can be reduced by saving the wasted compressed air.

What is Ultrasound?

Ultrasonic sound is a range of sound that is above human hearing capacity. Most people can hear frequencies from 20 Hz to 20 kHz. Sound from 20 kHz to 100 kHz can not be heard and is called “ultrasonic”. The Model 9061 Ultrasonic Leak Detector converts ultrasonic sound emissions to a range that is audible to people. (The sound generated by the ULD is 32 times lower in frequency than the sound that is received.)
