Hazardous Location Series HL40LV
Class 1 Division 1 and 2 Air Conditioners

All models UL Listed per 484, Special Purpose Air Conditioners. All models UL Recognized per NFPA 496: 2013, Purged and Pressurized Enclosures for Electrical Equipment. Meets NEC Class I Division 1, Groups A, B, C and D Hazardous Locations, when used with an approved Type X Purge System on the electrical enclosure. Meets NEC Class I Division 2, Groups A, B, C and D, Hazardous Locations when used with an approved Type Z Purge System on the electrical enclosures. Temperature Classification is T-4, 275°F/135°C.

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.

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.

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.

All units are fully gasketed for tight, leakproof installation, in compliance with the NEMA 4/4X Enclosure Ratings.

Allows user to attach auxiliary pressure supply.

All models feature a programmable temperature alarm to alert if early action is required.

All models feature a programmable thermostat, allowing more accurate and versatile performance features.

Hazardous Location Series models are designed to withstand shock and vibration in two different planes for a minimum of 4 hours per plane at 1G acceleration.

For applications in corrosive or other hostile environments such as those requiring Internal Corrosion Resistant Coatings, especially where chemical/moisture combinations are present.

R410a, an HFC having zero ozone depleting potential.
