Heat Controller MCL024AFC30C0PS Heat Pump 2 Ton 460V

Product Description

The HEAT CONTROLLER MCL024AFC30C0PS is a horizontal water source heat pump rated at 2 nominal tons and designed for three-phase, 460-volt electrical service. It uses R-454B refrigerant and delivers both heating and cooling through a coaxial heat exchanger that transfers energy between the refrigerant circuit and the water loop or ground water source. Cooling capacity reaches 27,500 BTU/h at 59 degrees F entering water temperature (EWT) in ground water mode, while heating output reaches 24,200 BTU/h at 50 degrees F EWT. The unit exceeds ASHRAE 90.1 efficiency standards and includes a performance monitoring system that signals potential equipment issues before they escalate. Licensed HVAC technicians install and service this equipment.

This unit is built for horizontal installation in commercial and light-commercial buildings where ceiling plenum or mechanical closet space is limited. The compact footprint makes it well suited for retrofit projects and tight mechanical spaces. Return air is configured for left-side entry. It operates effectively in both water loop heat pump systems and ground water heat pump systems, making it adaptable to a range of hydronic system designs commonly found in multi-tenant commercial buildings, hotels, and office applications.

Compatibility

Designed for use in horizontal water source heat pump systems operating on three-phase, 460-volt power with R-454B refrigerant, including ground water and closed-loop water loop applications in commercial environments.

Installation Notes

Installation and commissioning must be performed by a licensed HVAC technician familiar with water source heat pump systems and local mechanical codes. Disconnect and lock out all electrical power and isolate the water loop before servicing. Verify that the supply water temperature, flow rate, and system pressure are within the equipment design range before startup. Follow all applicable local, state, and national codes including ASHRAE standards and refrigerant handling requirements under EPA Section 608.
