STANDARD FEATURES
Baked Powder Finish
Built-in 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.
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.
Condenser Impeller Speed Controller
A solid state sensor reacting to the condenser coil temperature modulates the condenser impeller between minimum and maximum speed based on the coil temperature. This reduces noise levels, fan cycling, compressor cycling and prevents the unit from freezing.
Epoxy-Coated Condenser and Evaporator Coils
Condenser and Evaporator Coils are Epoxy-Coated. 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.
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.
Heavy-Duty Steel Shell
NEMA 12, 3R & 4 Ratings Maintained (UL50)
All units Maintain NEMA 12 & 3R Ratings. All units are fully gasketed for tight, leakproof installation, in compliance with the NEMA Type 4 Enclosure Ratings.
Programmable Temperature Alarm
All models feature a programmable temperature alarm to alert if early action is required.
Programmable Thermostat
All models feature a programmable thermostat, allowing more accurate and versatile performance features.
Six-Foot [1.8m] (minimum) 3-Wire Power Cord
UL/CUL Listed
ACCESSORIES AND OPTIONS
Adapter
A plate or plenum needed to replace older Kooltronic or competitor units.
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.
Lead-Lag Controller
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.
