3700 W Outdoor Enclosure Air Conditioner
3700 W outdoor enclosure air conditioner UP-AC-3700 is designed for sealed outdoor telecom and electrical cabinets that need active temperature control without bringing outside air into the enclosure. It combines closed-loop cooling, IP55 / IP65 protection and industrial communication options in a vertical cabinet-mount format.

UP-AC-3700: Outdoor Cabinet Cooling
This model is a practical fit for industrial and telecom enclosures where three-phase supply and higher continuous cooling are required. The internal and external air circuits remain separated, helping keep the protected enclosure closed while heat is rejected to ambient air.
The controller is factory set to 34 °C with 4 °C hysteresis. Communication options include EtherNet/IP, ModBus TCP and ModBus RTU for compatible monitoring systems.

When to Select 3700 W
Calculate equipment heat dissipation, solar gain and peak ambient temperature before selecting capacity. If the calculated load is close to 3700 W, review the next larger model rather than designing the system to operate continuously at its limit.
For quotation support, send enclosure dimensions, equipment heat load, maximum ambient temperature, target internal temperature, available voltage and quantity.
UP-AC-3700 FAQ
Is 3700 W the electrical power consumption?
No. 3700 W is the rated cooling capacity at L35/L35. The listed electrical power absorbed by this model is 880 W.
Can this unit be used in a sealed telecom cabinet?
Yes. It is intended for enclosure applications where the protected cabinet air should remain separated from the outdoor air circuit while heat is actively removed.
What information is needed for a quote?
Send cabinet dimensions, estimated heat load, site ambient range, target internal temperature, voltage, quantity and any communication requirement.
