STANDARD FEATURES
Baked Powder Finish
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 R134a Refrigerant
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.
Excess Pressure Control
Heavy-Duty Steel Shell
Low Temperature Control Thermostat
Electronic Thermostatic Low Temperature Control prevents over-cooling and provides energy-efficient operation.
Six-Foot [1.8m] (minimum) 3-Wire Power Cord
Water Regulating Valve
ACCESSORIES AND OPTIONS
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)
Condenser Access Panel
Expressly designed for quick, convenient access to the condenser coil for easy cleaning and servicing. Recommended for units operating in dirty environments, the panel is easily removed and replaced by use of a few fasteners, without removal of the entire rear cover panel.
Deep Drain Pan Kit
Enclosure Heater
Eliminates damaging condensation, increasing reliability of electrical enclosure components.
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.
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.
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.
Special materials or finishes
Special motors, line cords or connectors
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.
