CR290416G047

Overview

The nVent Hoffman CR290416G047 is a ProAir Harsh Environment Indoor Air Conditioner designed for sealed enclosures. It operates on 115 V AC at 50/60 Hz with an amperage rating of 13.5 A and a cooling capacity of 4,000 BTU/hr. The unit features a Level 2 controller and lacks a heat package. Constructed from steel with a light gray finish, it measures 29.5 inches in height, 15.75 inches in width, and 8.63 inches in depth. It provides protection against corrosive environments and supports operating temperatures ranging from -40 to 131 degrees Fahrenheit.

Feature Summary

• Designed for harsh environment applications to protect components exposed to corrosive conditions on the ambient side of the unit.
• Features a hinged front cover to facilitate easy maintenance and quick access.
• Includes a Level 2 controller for operational management.
• Constructed from steel to ensure durability in industrial settings.

Applications

• Cooling sealed electrical enclosures in corrosive indoor environments
• Protection of sensitive electronic components in harsh industrial atmospheres
• Temperature regulation for NEMA 3R/4/12 rated enclosure installations

Procurement Notes

Verify that the application requires air conditioning only, as this model does not include a heat package. Confirm compatibility with the specific enclosure dimensions and the required 115 V AC power supply. Ensure the installation environment falls within the specified operating temperature range of -40 to 131 degrees Fahrenheit. Check for any specific mounting requirements associated with the CR29 series form factor.

Selection Notes

Select this model when corrosion resistance is critical for the ambient side of the cooling unit. It is suitable for indoor use where sealed enclosure protection is necessary. Consider the 4,000 BTU/hr capacity relative to the internal heat load. The absence of a heating function distinguishes it from dual-function units. Verify that the physical dimensions fit the available space within the target enclosure.

Part Context

This unit belongs to the nVent Hoffman ProAir MCL Indoor Medium/Full Sealed Enclosure Air Conditioner series. It is engineered specifically for harsh environment applications, offering enhanced protection compared to standard air conditioners. The CR29 designation indicates its size class within the Hoffman product line, tailored for medium to full-sized sealed enclosures requiring robust thermal management.

Replacement Considerations

Direct replacement requires matching the 115 V AC input, 4,000 BTU/hr capacity, and CR29 physical footprint. Verify if the existing setup requires heating functionality, which this model lacks. Ensure the new unit supports the same Level 2 controller interface if integration with existing controls is planned. Confirm material compatibility for corrosive environments.
