• CFC-Free Refrigerant

• 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 reusable, they may be washed and recoated with the appropriate filter recoating adhesive. Replacement filters are available and can be ordered online at kooltronic.com/spareparts.
• NEMA 12 Rating Maintained (UL50)
All units are fully gasketed for tight, leak-proof installation, in compliance with the NEMA 12 Enclosure Ratings.
• Reversible Condenser Outlet Blower
• Thermostatic Low Temperature Control
• UL/CUL Listed/ Recognized*
All models are UL/CUL Listed.

• Compressor Short Cycle Protector
Available as a Standard Feature on models with Programmable Thermostat. Protects the compressor from possible damage due to harmful short cycling, (frequent starting) where temperature controls enable the compressor to restart frequently or after a power interruption. These conditions could be due to low or fluctuating heat loads within the electrical enclosure or a power failure. The Compressor Short Cycle Protector will prevent the compressor from starting when it has been shut off for less than several minutes or the power was interrupted. By limiting the number of compressor starts per hour, the life of the compressor is prolonged. It is recommended where installations are subject to solar gain and or changes in the enclosure internal load due to the degree of usage of the equipment being cooled. It is also recommended where higher capacity units are specified in anticipation of the future addition of heat producing equipment being added to the enclosure.
• Condensate Evaporator Kit
Condensate evaporator kits are available for attachment to the bottom of Air-Cooled Panel Mounted Air Conditioners. Condensate is collected, vaporized and discharged to the surrounding air. All units include a safety overflow drain which discharges excessive condensate when required. Overflow may occur when cabinets are poorly sealed, or when cabinet doors are frequently opened, permitting the invasion of moisture-laden air. Models: KCH30 (115v) or K2CH30 (230v)
• Enclosure Heater
Eliminates damaging condensation, increasing reliability of electrical enclosure components.
• 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.
• Internal Corrosion Protection
This protection increases reliability in hostile environments. This protection for the refrigeration system consists of an air cured coating applied to the 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 GuardianX 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.
• 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.
• Low Ambient Kit
Maintains sufficient operating pressures when ambient temperatures drop below 50°F. Includes a compressor heater and a pressure device that senses the reduced discharge pressure and modulates the condenser blower. Effective to a minimum ambient temperature of 0°F.
• Mounting Hinge
(Left-hand or Right-hand) Allows the air conditioner itself to be used as a cabinet door. (Caution: The cabinet must be able to support the full weight of the unit in open position.) Specify left-hand (LH) or right-hand (RH), determined by facing the mounting side of the unit.
• Remote Thermostat Relay
Used only with a user-installed remote thermostat or the Kooltronic KLLC100 Lead Lag Controller, this 24VAC relay can be used for the sequential operation of two units or with a single unit. An external terminal strip is provided for field interconnection. NOTE: User-installed thermostat must have a set point of 75°F with a differential of 11°F. NOTE: A factory installed thermostat is not provided with this option.
• 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 controls or indicators
• Special motors~ line cords or connectors
• Special paint finishes
• Stainless or Aluminum Shell
• 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.
