STANDARD FEATURES
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 (-29°C) to 250°F (121°C). Tube axial fans are rated to perform at 14°F (-10°C) to 158°F (70°C) and are designed to meet UL, CSA and VDE.
CFC-Free Refrigerant
CFC-free R134a Refrigerant is used
Closed-Loop Cooling
The enclosure interior airflow system is isolated from the ambient airflow or waterflow system. No ambient air can invade the cool, dehumidified sensitive component compartment.
Compressor Short Cycle Protector
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.
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.
NEMA 12 Rating Maintained (UL50)
All units are fully gasketed for tight, leak-proof installation, in compliance with the NEMA 12 Enclosure Ratings.
Programmable Thermostat
All models feature a programmable thermostat, allowing more accurate and versatile performance features.
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.
UL/CUL Listed
ACCESSORIES AND OPTIONS
Adapter
A plate or plenum needed to replace older Kooltronic or competitor units.
Aluminum Shell
Where light weight and/or compatibility with appearance of aluminum enclosures are required. Unpainted Type 5052 is standard. Other types and ultraviolet-resistant baked powder finish are available.
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.
High Capacity Condensate Evaporator
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.
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.
Lead-Lag Controller
Lifting Eyes
Heavy-gauge steel lifting eyes, attached to the side panels, assist in positioning units.
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 heat exchanger.
Remote Monitoring
An optional feature for models with Programmable Thermostat, Remote Monitoring provides temperature data for warning of early action required.,Accomplished through a Hot Key connection from the Programmable Thermostat to a monitoring system (not supplied) that is ModBus-RTU compatible (i.e. XWEB500/3000/300) via an external 2-position terminal block.
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 materials or finishes
Stainless Steel Shell
Weather Protection Kit
For outdoor installations subject to invasion by rain, snow or windblown dirt, special deflectors shield the condenser air inlet and outlet ports. Air conditioners or heat exchangers installed outdoors may also require special exterior paint. NOTE: Units using the Weather Protection Kit are not UL Listed.
