FAQs: Cabinet Panel Coolers

Below is a list of Frequently Asked Questions relating to our Panel Coolers. If you need additional help with your application and/or can't find an answer to your question, please call our factory at 1-705-770-4455 or email an Application Engineer at support@stream-tek.com.

      1. Can I use a Vortex Tube to cool my electrical enclosure instead of the Cabinet Panel Cooler?
      Yes, however there are clear-cut advantages to using the STREAMTEK™ Cabinet Panel Cooler for this application.
    • Cabinet Panel Coolers have a pressure release valve to allow warm air from the electrical enclosure to escape the cabinet.
    • Cabinet Panel Coolers have been fine tuned to achieve maximum refrigeration; this cannot be adjusted. Vortex Tubes on the other hand can be adjusted by the user, leaving them open to poor operation and miss-adjustment.
    • Cabinet Panel Coolers have been engineered to reduce noise levels drastically from that of the sole Vortex Tube.
      2. How to do I stop the solenoid valve from chattering?
      A .002 microfarad capacitor can be wired across the leads on the thermostat to stop it from chattering. This chattering can sometimes occur by a very slow temperature change. The capacitor simply desensitizes the thermostat to stop the chattering effect. The Capacitor is available FREE OF CHARGE at special request.
      3. What is the cooling capacity (BTU/Hr.) of your Cabinet Panel Coolers?
      STREAMTEK manufactures Cabinet Panel Coolers which produces 550 – 2,800 BTU/Hr. from a single unit. If you require additional cooling, we have dual cooler units from 3,600 – 5,600 BTU/Hr.
      4. How do I know which Cabinet Panel Cooler I should use?
      It's never been easier! Simply complete our Cabinet Cooling Sizing guide and fax it to us at +1(705)252-6343. A STREAMTEK™ Application Engineer will contact you within 12 hours with a recommendation. If you wish to determine the size requirements yourself, click here for step-by-step instructions.
      5. Can condensation occur within our control panels when using STREAMTEK™ Cabinet Panel Coolers?
      No. The STREAMTEK™ Cabinet Panel Cooler will purge warm/moist air from inside your enclosure. The cool air that is being injected into the cabinet will then start to pick up heat, which in-turn causes the humidity to drop. A continuous operation Cabinet Panel Cooler will keep the relative humidity at about 45%. It is imperative that all openings in your panel are closed off, as humidity from the ambient air could cause condensation within your panel.
      6. Where should the Cabinet Panel Cooler and Thermostat be installed?
      The STREAMTEK™ Cabinet Panel Cooler must be installed at the top of the cabinet through standard knockout, and secured with locking nut. A thermostat at the top of the cabinet is best (but not required), as this is the hottest spot due to the rising hot air.
      7. What is the material of construction of the Cabinet Panel Cooler?
      Stainless Steel (Type 303) is the material of construction on ALL coolers. They are corrosion proof, long lasting, and the stainless provides the best cold temperature drop.
      8. What is the force of air inside the cabinet enclosure?
      The pressure within the cabinet can build up to approximately 2 PSIG; depending on how tightly seal the cabinet is.
      9. How does the exhaust air leave the cabinet?
      The STREAMTEK Cabinet Panel Cooler incorporates it's own vent into the mounting base. The cold air enters the cabinet through the center brass tube, while the cabinet air exhaust vents through the perimeter vent on the base of the cooler.
      10. What is the air consumption?
      Each application will have a different heat load which will determine the air consumption of your cooler. Generally you can expect from 8 to 80 SCFM @ 100 PSIG. This will provide cooling from 550 - 5,600 BTU/Hr. It's important to note that this is only when the adjustable thermostat calls for cooling!
      11. What kind of increase in noise pollution can i expect from your coolers?
      Our coolers are targeted for factory and industrial type applications. Though use within an office and/or lab is possible, it's not typically practical. When our cabinet enclosure coolers are placed near stamping machines, mills, lathes, boilers, etc. one would not even know when the cooler operates. On average, expect between 70-75 dBA sound levels.
