Intrepid Series EP56TR-4
Air-Cooled Panel-Mounted Air Conditioners

Heavy-duty steel shell with powder-baked finish (ANSI 61 gray). Custom color options are available.

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.

A speed control sensing bulb located in the condenser air outlet area switches the condenser fan between minimum and maximum speed based on the ambient temperature. This reduces noise levels, fan cycling, compressor cycling and prevents the unit from freezing.

120V or 240V heater attached to the compressor crankcase to maintain appropriate temperatures during cold operating conditions.

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.

Electronic Thermostatic Low Temperature Control prevents over-cooling and provides energy-efficient operation.

Used only with a user-installed remote thermostat, 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 supplied with this option.

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.

R410a, an HFC having zero ozone depleting potential.
