NEMA

TYPE 4/4X
MAINTAINED
Description

Designed specifically for NEMA 4 and 4X Enclosure applications that require washdown or are subject to outdoor storm conditions, KOOLTRONIC Integrity NEMA 4/4X Legacy Air Conditioners protect the ratings of NEMA 4 or 4X Enclosures.

These exclusive patented UL/CUL Listed Panel-Mounted Air Conditioners provide superior closed-loop cooling and also protect against the hazards specified for both Indoor and Outdoor NEMA 4 and 4X Enclosures. Tested and rated by universally recognized Underwriters Laboratories, these uniquely-designed 304-2B Stainless Steel Air Conditioners prevent unwanted environmental penetration of NEMA 4 and 4X Enclosures as they provide a clean, cool internal environment.

These units can be mounted interchangeably with same series KOOLTRONIC Integrity NEMA 4/4X Heat Exchangers for maximum flexibility in the event that cooling requirements change.

For extreme ambient temperatures and/or severely contaminated environments, the use of Water-Cooled Air Conditioners or Water-Cooled Heat Exchangers is recommended.

KOOLTRONIC also designs and manufactures a variety of air conditioners to meet unique specifications. We invite your inquiries about our modification and custom-design capabilities.

Many popular units are available as 3D solid models for customer system integration. Contact Kooltronic for details.

 
Standard Features

  • All Models UL/CUL Listed
    • All Guardian Series models are UL/CUL Listed.
  • CFC-Free Refrigerant
    • CFC-free R134a Refrigerant is used in all air conditioners for which compatible compressors are available. Consult KOOLTRONIC for status at time of requirement.
  • Filter
    • All KOOLTRONIC filters consist of a multi-layer grid of sturdy corrugated aluminum, securely held in a one-piece aluminum frame. Filters are required wherever air is drawn into an electronics enclosure or related cooling equipment to keep internal parts as clean as possible.

      A non-drying adhesive coating traps a high percentage of particulate matter. These filters are reuseable, they may be washed and recoated with the appropriate filter recoating adhesive. Replacements are available for those which become damaged or otherwise non-serviceable

  • Gasketed flanges on all four mounting edges
  • Head Pressure Control Switch
    • A control device to minimize compressor cycling and prevent evaporator coil icing.
  • Heavy-duty Stainless Steel Shell
  • Internal Corrosion Protection
    • An air cured coating is sprayed on copper lines and brazed joints on the condenser side, providing a degree of protection from corrosive environments. This coating will withstand 1000 hours of salt spray per the ASTM B 117 test method. Also see Stainless Steel Cabinet or Integrity NEMA 4/4X Air Conditioners. NOTE: Severe operational environments such as waste water treatment and salt spray are likely to cause corrosion failure over a period of time regardless of coating. Warranty: Corrosive conditions may affect the warranty coverage. Consult factory for warranty limitations in corrosive environments. NOTE: For additional corrosion protection options, contact factory.
  • NEMA 4/4X Ratings maintained (UL50)
    • All units are fully gasketed for tight, leakproof installation, in compliance with the NEMA 4/4X Enclosure Ratings.
  • Six foot [1.8m] (minimum) 3-wire power Cord
  • Thermostatic Low Temperature Control
    • Thermostatic Low Temperature Control prevents over-cooling and provides energy-efficient operation.
