KOOLTRONIC Air-Cooled Rack-Mounted Air Conditioners are particularly suited for applications where internal horizontal mounting is preferred over external panel, door or top mounting. Air-cooled models are typically mounted internally at either the top or bottom of the cabinet.
KOOLTRONIC Rack-Mounted Air Conditioners all include EIA-notched flanges. Air-cooled models are provided with attractive 19-inch wide stain-less steel grilles and knurled captive fasteners for easy removal. Grille area is 65% open. If preferred, side rails can be supplied.
Outdoor or corrosive environments require weather protection and/or special internal and external protective features.
STANDARD FEATURES:
CLOSED-LOOP COOLING: The enclosure interior airflow system is isolated from the ambient airflow system. Ambient air can not invade the cool,dehumidified sensitive component compartment.
BALL-BEARING MOTORS: All blower motors are UL/CSA Recognized and include automatic-reset thermal overload protection and double-sealed or double-shielded precision ball bearings. Special permanent lubricants perform over a broad temperature range: -20°F [-28.9°C] to 250°F [121.1°C].
BLOWERS: All centrifugal blowers are Kooltronic-designed and built, to provide optimum airflow and pressure for each Air Conditioner design.
RUGGED CONSTRUCTION: Precision-engineered heavy gauge steel construction of all cabinets and blowers insures Air Conditioners will stand up under tough applications.
BAKED POWDER FINISH: Durable, baked-on gray powder finish is standard. Other finishes are available.
POWER: Available in 115 VAC, 60 Hz or 50/60 switchable and 230 VAC, 50 Hz or 60 Hz.
REFRIGERANT: CFC-free R134a Refrigerant is used in all H7 Series Air Conditioners.
PERMANENT FILTERS: Multi-layer grid of sturdy, corrugated aluminum in an aluminum frame. May be reused after washing off accumulations and spraying with A-16 Recoating Adhesive.
CONDENSATE EVAPORATOR: Built-in Condensate Evaporator eliminates need for draining condensate under normal operating conditions. May not be adequate in extremely high humidity with open or leaky enclosure. Overflow condensate drain fitting and hose are included.
LOW TEMPERATURE CONTROL: Thermostatic Low Temperature Control prevents over-cooling and provides energy-efficient operation.
EMI/RFI SUPPRESSOR: EMI/RFI Suppressor minimizes transient line spikes during on/off cycling.
POWER CORD: All models have six foot [1.8m] SJT-type 3-wire power cords with appropriate plugs.
INSULATION: All cold components, lines and the evaporator compartment are insulated with high-performance insulation for maximum efficiency.
GASKETING: All units are fully gasketed for tight, leakproof installation, in compliance with the NEMA 4/4X Enclosure Rating.
QUALITY ASSURANCE: Refrigeration system components are kept sealed until charged with refrigerant; all brazed joints are thoroughly leak-tested; each unit is functionally tested before shipment.
INSTALLATION: Detailed Installation and Operator's Manual, with drawings, mounting plan and spare parts list is included with each unit.
UL/CUL LISTED OR RECOGNIZED: All H7 models are UL/CUL Listed or Recognized. Listed Air Conditioners have an "L" at or near the end of the model number and Recognized units have an "R" at or near the end of the model number. All Recognized models are available as Listed at added cost.
