About MRCOOL

MRCOOL is a manufacturer of HVAC equipment and air-movement products, with a catalog that spans ductless mini-split systems, industrial fans, and installation accessories. The brand is known for its DIY-oriented mini-split lines, which use pre-charged refrigerant lines and quick-connect fittings to reduce the need for field brazing and vacuum evacuation during installation. 3G Electric supplies MRCOOL equipment globally to plant engineers, maintenance managers, and procurement specialists who need documented specifications and consistent availability across building-services and light-industrial applications.

The MRCOOL product range covers several distinct families. Pre-charged quick-connect mini-split systems are available in nominal capacities from 9,000 BtuH to 36,000 BtuH, with single-phase power at 115V AC or 230V AC depending on the model. These systems are configured as air handlers with matched outdoor units and are intended for zone conditioning in residential, office, and light-commercial spaces where ductwork is impractical. Coverage ratings published for the line range from approximately 150 sq ft to 1,500 sq ft, depending on capacity and building load. The mini-split family is supported by accessories including line covers for concealing refrigerant and control wiring, and steel wall-mounting brackets rated to 440 lb for elevating condenser units off the ground.

A second MRCOOL product family covers industrial air movement. This includes washdown-rated ceiling- and wall-mount fans with blade diameters of 16 ft and 24 ft, driven by 1 hp or 2 hp single-phase motors operating on 220 to 240V AC. These fans are built with totally enclosed fan-cooled motors and are offered with oscillation and multiple speed settings, making them suitable for large facilities that require high-volume air movement and washdown-compatible construction. A separate line of oscillating tower fans uses a bladeless design and a brushless DC motor, with eight speeds and a remote control, operating on 120V AC single-phase power in a mobile plug-in configuration.

For technical buyers, the relevant MRCOOL specifications are straightforward: capacity in BtuH, voltage and phase, coverage area, motor horsepower, blade diameter, speed count, and mounting type. The mini-split systems are pre-charged and quick-connect, which affects installation labor and tooling requirements. The industrial fans are specified by blade diameter, motor rating, and washdown rating. Accessories are specified by compatibility, material, and load rating. 3G Electric maintains these products as catalog items and supports the line by providing specification data, part-number cross-reference, and quotation support for single-unit and multi-unit requirements. Buyers can request current lead times, confirm voltage and capacity configurations, and obtain documentation needed for submittals or maintenance planning.

Frequently asked questions

Common questions about MRCOOL from 3G Electric.

What capacities are available in the MRCOOL pre-charged quick-connect mini-split line?

MRCOOL pre-charged quick-connect mini-split systems are listed in nominal capacities including 9,000 BtuH, 12,000 BtuH, and 36,000 BtuH. Voltage depends on capacity: the 9,000 BtuH and 12,000 BtuH models operate on 115V AC single-phase, while the 36,000 BtuH model operates on 230V AC. Published coverage ranges from approximately 150 sq ft to 400 sq ft for the 9,000 BtuH unit, 400 sq ft to 1,500 sq ft for the 12,000 BtuH unit, and up to 1,500 sq ft for the 36,000 BtuH unit. Actual coverage depends on building load, insulation, and climate.

What does pre-charged quick-connect mean on a MRCOOL mini-split system?

On MRCOOL mini-split systems, pre-charged quick-connect refers to factory-charged refrigerant lines and fittings that join the indoor air handler to the outdoor unit without field brazing or vacuum evacuation. The line sets are supplied with the system and connect using mechanical fittings. This reduces installation steps and tooling compared with conventional split systems, but the connection points still require proper torque and leak checking per the manufacturer's instructions. Line covers, such as the MRCOOL MLG450-T, are available separately to conceal the refrigerant lines and control wiring.

What are the specifications of the MRCOOL washdown-rated industrial ceiling fans?

MRCOOL washdown-rated industrial ceiling fans are offered with 16 ft and 24 ft blade diameters. The 16 ft model uses a 1 hp motor, and the 24 ft model uses a 2 hp motor. Both operate on single-phase 220 to 240V AC and provide 10 speeds with oscillation. They are designed for ceiling or bracket mounting in large facilities that require high-volume air movement and washdown-compatible construction. Motors are totally enclosed fan-cooled. Confirm mounting structure, available headroom, and electrical supply before specifying.

What is the load rating of the MRCOOL MB440A wall-mounting bracket?

The MRCOOL MB440A is a two-piece steel wall-mounting bracket for air conditioner condensers, rated to a maximum of 440 lb. It measures 36 inches in length and 27 1/2 inches in width and includes mounting hardware. The bracket elevates the condenser off the ground, which helps protect the unit from debris and allows proper airflow and service access. Verify wall construction and anchoring can support the combined condenser and bracket load, and follow the manufacturer's installation instructions for clearances.

What are the electrical requirements for the MRCOOL oscillating tower fan?

The MRCOOL oscillating tower fan is a mobile plug-in unit operating on 120V AC single-phase power. It uses a brushless DC motor and offers eight speeds with an included remote control. The housing is plastic, and the fan uses a totally enclosed fan-cooled motor. The bladeless design is intended for home and office use. Because it is a plug-in appliance, no hardwiring is required, but the circuit should be sized for the fan's nameplate current and any other loads on the same branch.

Does 3G Electric supply MRCOOL accessories such as line covers and mounting brackets?

Yes. 3G Electric supplies MRCOOL accessories including line covers for ductless mini-split systems, such as the MLG450-T, and steel wall-mounting brackets for air conditioner condensers, such as the MB440A. These items are cataloged alongside the mini-split systems and industrial fans. Accessories are specified by compatibility, material, and load rating. For project requirements, provide the host unit model number and mounting or routing conditions so the correct accessory can be quoted.
