GT-PG (50YE) Series

GT-PG Design Features

The GT-PG Series has abundant features and industry leading efficiency.

Application Flexibility

•Eight Capacities 018, 024, 030, 036, 042, 048, 060 and 070.

•Extended range operation (20-120°F EWT) and flow rates as low as 1.5 gpm per ton.

•Vertical packages with either true right or true left return air options.

•Internally trapped condensate drain.

•Optional variable speed ECM fan motor adapts to various duct systems.

•Internal electric heat unit (optional) designed for easy field installation.

•Circuit breaker protected loop and hot water generator pumps.

•Field selectable low temperature protection setting for well or loop.

•Standard pre-installed 2” filter frame with 2” high performance MERV 11 pleated air filter.*

Operating Efficiencies

•Puron® HFC-410A zero ozone depletion refrigerant.

•High efficiencies in AHRI/ISO/ASHRAE/ANSI 13256-1 single stage ratings for heating COPs, cooling EERs with low water flow rates.

•Multi-speed tap PSC fan or optional ECM variable speed fan for ultra high efficiencies and unsurpassed comfort.

•Wide operating temperature range and high efficiency allow shorter loops.

•Optional hot water generator with internal pump generates hot water at considerable savings.

•Rugged and highly efficient next generation Copeland scroll compressors provide the extremely high efficiencies and capacities.

•Oversized coaxial tube water-to-refrigerant heat exchangers operate at low liquid pressure drop. Convoluted copper (and optional cupro-nickel) water tube functions efficiently at low-flow rates and provides freeze-damage resistance.

•Oversized tin-coated, rifled tube/lanced aluminum fin, air to refrigerant heat exchangers provide high efficiency at low face velocity.

•Large low RPM blowers with optional variable speed fan motors provide quiet, efficient air movement with high static capability.

Service Advantages

•Removable panels - 3 for compressor, 2 for air handling compartment.

•Low profile control box grants easy access to all internal components.

•Factory installed liquid line filter/drier.

•Brass swivel-type water connections for quick connection and elimination of wrenches or sealants during installation.

•Bi-directional thermal expansion valve.

•CXM control features status light with memory for easy diagnostics.

•Unit Performance Sentinel alerts homeowner of potential performance issues.

•Circuit breaker protected 75VA control transformer.

•Optional ECM motor includes control board with thermostat signal diagnostic LEDs, airflow display LED (100 CFM per flash), and simplified CFM selection.

•Insulated divider and separate air handling/compressor compartments permit service testing without air bypass.

•Fan motors have quick attach wiring harness for fast removal.

•Internal dropout blower for easy servicing.

•High and low pressure service ports on refrigerant circuit.

•Accurate refrigerant sensing low temperature protection.

Factory Quality

•All units are built on our Integrated Process Control Assembly System (IPCS).The IPCS is a unique state of the art manufacturing system that is designed to assure quality of the highest standards of any manufacturer in the water-source industry. Our IPCS system:

-Verifies that the correct components are being assembled.

-Automatically performs special leak tests on all joints.

-Conducts pressure tests.

-Performs highly detailed run test unparalleled in the HVAC industry.

-Automatically disables packaging for a “failed” unit.

-Creates computer database for future service analysis and diagnostics from run test results.

•All units are water run-tested in all modes to insure efficiency and reliability.

•Heavy gauge galvanized steel cabinets are epoxy powder coated for durable and long-lasting finish.

•All refrigerant brazing is done in a nitrogen atmosphere.

•All units are deep evacuated to less than 100 microns prior to refrigerant charging.

•All joints are both helium and halogen leak tested to insure annual leak rate of less than 1/4 ounce.

•Coaxial heat exchanger, refrigerant suction lines and all water lines are fully insulated to eliminate condensation problems in low temperature applications.

•Noise Reduction features include: double isolation mounted compressors; insulated compressor compartment; interior cabinet insulation using 1/2” coated glass fiber and optional variable speed fan.

•Safety features include: high pressure and loss of charge to protect the compressor; condensate overflow protection; low temperature protection sensors to safeguard the coaxial heat exchanger and air coil; hot water high-limit and low compressor discharge temperature switch provided to shut down the hot water generator when conditions dictate. Fault lockout enables emergency heat and prevents compressor operation until thermostat or circuit breaker has been reset.

Simplified Controls

•CXM solid state control module.

•‘CFM’ LED displays airflow (optional ECM motor).

•Dehumidification mode for higher latent cooling (optional ECM motor).
