STANDARD FEATURES

  • Closed-Loop Near-Ambient Cooling
  • Epoxy-coated aluminum element
  • 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
  • NEMA 4/4X Rating Maintained (UL50)
    • All units are fully gasketed for tight, leakproof installation, in compliance with the NEMA 4 and 4X Enclosure Ratings.
  • Stainless Steel Shell
    • For applications in corrosive or other hostile environments such as those requiring Internal Corrosion Resistant Coatings, especially where chemical/moisture combinations are present.
  • UL/CUL Listed

ACCESSORIES AND OPTIONS

  • Filter Recoating Adhesive
    • This compound is a superior product for recoating filters after washing. The adhesives penetrate dirt layers to keep the filter surface tacky for longer effective performance between washings.
  • Lifting Eyes
    • Heavy-gauge steel lifting eyes, attached to the side panels, assist in positioning units.
  • Low Airflow Detector
    • Similar to the Airflow Switch shown in the Blower Accessories Section, the switch is installed in a suitable location in the air conditioner to detect loss of airflow, and sends a signal to a terminal block, through which user-installed wiring and warning devices are activated.
  • Other voltages and frequencies
  • Replacement Filters
    • 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.
  • Special materials or finishes
  • Special motors, line cords or connectors
  • Temperature Alarm
    • A thermostat is mounted inside the cabinet and attached to a sensor in the warm air return. When the air temperature increases to the set point, a signal is sent to a terminal block. User-installed wiring from the terminal block to local and/or remote warning devices (light, bell, siren, etc.) can be for normally open or closed operation.

For KNHX38 models the filter part number is 10871F.
