EIC’s Air Conditioners helping to maintain PLCs for turnkey packaging industry QA application


Packaging Industry


Turnkey Automation

An automation engineering company who designs and implements turnkey solutions for the packaging industry contacted EIC Solutions to review their application. They were using control panels to house programmable logic controllers (PLC’s) for inspection systems which remove improperly printed cans from their packaging line. The PLC is programmed with accept/reject parameters that signal the high-speed diverter to sort and reject defective products from the conveyor system. The customer was experiencing heat build-up in the PLC panels that house sensitive packaging and processing equipment which could lead to downtime or failure. Their primary concerns centered on PLC’s, servo motor drivers, station monitors, and cameras. Additionally, this equipment was subject to harsh conditions including:

  • Regular Wash-Down

To maintain sanitary conditions, regular wash-down of the equipment is required. The frequent exposure to water and harsh chemicals can damage and shorten the life of electrical components. Selecting the proper equipment protection is critical to avoid downtime while maintaining sanitary conditions.

  • Corrosive Chemicals

Materials are subject to deterioration and failure due to the corrosive chemicals used in the cleaning process. Systems must be able to resist corrosion to be implemented into this environment.

  • Fluctuating Temperatures

Manufacturing plant floors using automated packaging lines often experience fluctuating temperature ranges due to processing equipment including dryers, ovens, and flash freezers. Implementing equipment that can withstand these fluctuations can reduce the failure of sensitive components.

These automated systems needed to function without interruption while being exposed to severe conditions which were a major issue for the customer. EIC Solutions has extensive experience in the automated packaging industry and recommended that the customer integrate a robust, thermoelectric air conditioner into their existing control panels. Incorporating EIC’s products to environmentally protect sensitive electronics prevents failure caused by heat build-up and reduces the need to replace costly equipment. After reviewing the customer’s application EIC Solutions recommended:

ThermoTEC 120 Series 200 BTU Thermoelectric Air Conditioner

24/28VDC power configuration

RS-120V Rain Shroud

For an added degree of protection in wash-down environments

ThermoTEC 140 Series 400 BTU Thermoelectric Air Conditioners

24/28 VDC power configuration

Rain Shroud - Vertical/Side Mount (200 BTU Models)

For an added degree of protection in wash-down environments

EIC’s thermoelectric air conditioners were the ideal solution for this application. The customer implemented these enclosure coolers designed to withstand regular wash-down and corrosive chemicals. This solution met their cooling requirements which reduced failure and ensured continuous automated operation. The ThermoTEC series thermoelectric air conditioners were integrated into existing enclosures. They are also available as a complete package including both the enclosure and air conditioner. EIC’s products can also be customized to meet the needs of your specific application. We review all job requirements and specifications to determine the best solution to protect your sensitive equipment. If you need a recommendation on your application please contact a knowledgeable EIC Solutions’ sales engineer.
