Mammoth Water Source Heat Pumps

Mammoth offers a complete line of high efficiency horizontal units from 3.0 kW - 19.3 kW. E series Mammoth water source heat pumps contains five cabinet sizes with a similar shape allow for easy layout and installation. Each unit is run-tested with water in the cooling and heating modes.

Mammoth water source heat pumps are listed for product safety by CCC & CE or ETL.

● Eleven units from 3.0 to 19.3 kW

● Fully run tested with water

● Compact size

● CCC and CE listed

● Microprocessor-based control system including fan speed adjustment and condensate overflow protection

● Optional geothermal application

Unit Construction

The cabinet is constructed of galvanized steel. Internal metal parts are also fabricated from galvanized steel. Cabinet insulation is 15mm thick, skin-coated fiberglass/PE. The entire bottom panel is insulated with the same material to prevent condensation and reduce noise transmission. Three access panels for the compressor, fan and control box sections allow service to all major components without removing the unit from the ceiling. The control box has its own entrance panel to limit exposure to other sections not requiring service. All major electrical components, including transformer, relays, contactor(s) and circuit board, are located inside the control box making it convenient to service the unit.

A 10 mm thick reusable filter is supplied in a factory-mounted filter bracket designed to accommodate a return air duct connection.

The units include factory-mounted hanger brackets and have four top-panel adjustable brackets with factory-mounted grommets.

Mammoth water source heat pumps incorporate female water fittings outside the cabinet for connection to flexible hoses. A 19 mm O.D. condensate connection is located outside the cabinet, adjacent to the water connections

Refrigeration System

Refrigeration system for each circuit consists of high efficiency compressor, either rotary type or scroll type, a coaxial water-to-refrigerant heat exchanger, an airside coil, thermal expansion valve or capillary tube, access valve, reversing valve and safety controls.
The compressor is mounted on heavy - gauge mounting rails to dampen compressor vibration. In addition, the compressor is also mounted on neoprene isolators. This dual isolation ensures minimal noise transmission and quiet operation. Each refrigeration circuit has high and low side access valves for servicing.

The water-to-refrigeration coaxial coil consists of an inner twisty tube and a steel outer tube.

Large tube diameters prevent clogging, unlike brazed type heat exchangers which require mesh strainers. The air coil is a copper-tube, aluminum finned selected for high efficiency.

The reversing valve is energized in the heating mode and is fail-safe to the cooling mode.

Safety controls include high and low (loss of charge protection) refrigeration pressure switches for each circuit. A lockout relay prevents the compressor from operating if any of the safeties trip.

Fan Section

The fan section consists of the fan wheel/housing assembly, fan motor and drain pan. Airside components are separated from the compressor section to limit noise transmission from the compressor. The drain pan extends past the coil into the compressor section for easy cleaning. It is insulated from the unit casing to prevent sweating.

Mammoth water source heat pumps are capable of having two different discharge air arrangements: straight or end, both can be factory supplied in either configuration or simply converted from one to the other in the field. Mirror image units allow a "reversed" configuration. All units have a direct drive fan assembly. The fan motor is a multispeed, with internal overload protection. With a maximum speed of 1200 rpm, the fan is quieter than the smaller of diameter motors used in similar products. Each centrifugal fan wheel is balanced for minimum vibration.
