ClimateMaster introduces Tranquility® Vertical Stack (TSM) Series heat pump units for geothermal heating and cooling systems, offering simple, cost-effective installation combined with the industry's highest energy performance in the vertical stack product category.

ClimateMaster announces the launch of its Tranquility® Vertical Stack (TSM) Series heat pump units, offering simple, cost-effective installation combined with the industry's highest energy performance in the vertical stack product category. Available in ¾- through 3-ton capacities, the units are engineered to provide energy-efficient heating and cooling as part of either boiler/cooling tower or geothermal heating and cooling systems.

Designed for a variety of applications including educational, office, hospitality, apartment and condominium buildings, the TSM Series streamlines installation as its risers, cabinet and chassis are available for shipment individually or in combination. This and ClimateMaster's phase scheduling allow for the units' delivery and installation to seamlessly coincide with the overall building's construction schedule. The space-saving TSM Series units are also installed virtually out of site behind drywall, which translates to a clean and visually appealing end result.

"The next-generation TSM Series of heat pumps leapfrogs the industry to deliver the highest efficiency and the latest technology," said Raj Hiremath, marketing director at ClimateMaster. "Additionally, these new units feature the only communicating system on the market, providing advanced configuration and diagnostic capabilities, while also operating quietly and providing ultimate indoor comfort."

Featuring optional iGate™ (DXM2) controls, TSM Series units offer 4-wire connections with an ATC thermostat. iGate™ controls additionally facilitate configuration, diagnostics and monitoring in Plain English on an ATC thermostat or ACD diagnostic tool.

The TSM Series' chassis is comprised of high-strength galvanized steel cabinetry, with an electrical access panel, compressor enclosure, male NPSH water connection fittings, high- and low-voltage wire harnesses and a 1-in (25mm) filter. It is equipped with a standard CXM controller, loss-of-charge and high-pressure switches, a water coil low-temperature cutout, lockout safety circuit reset (at thermostat or disconnect), LED fault indication light, five-minute anti-short cycle, random start, high- and low-voltage protection, condensate overflow protection and a 24VAC or dry contact for the alarm.

The sealed and tested refrigerant circuit includes an expansion valve metering device, high- and low-side Schrader ports and interconnecting copper tubing through which environmentally friendly EarthPure® HFC-410A refrigerant is circulated. A 4-way, pilot-operated reversing valve, tube-in-tube water-to-refrigerant coil, and optional high-density noise suppressant lining in the compressor compartment complete the chassis design, which is compatible in WLHP, GWHP and GLHP applications.

An outer galvanized steel cabinet with powder coat-finished drain pain features electrical and blower access panels and foil-faced fiberglass insulation. Field-selectable supply air openings allow for maximum installation flexibility on the jobsite, and a terminal block located inside the control box facilitates simplified field wiring connections. TSM Series units additionally include a multiple-speed, permanently lubricated PSC direct-drive blower motor, full port shut-off valves with memory stop, stainless steel braided hose kits and an optional pre-programmed, variable speed high-efficiency ECM motor for optimum CFM.
