Carrier GT-G, GT-S, GT-PX specifications Internally-mounted field installed Flow Controller

GT-S

Application Flexibility

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

•Voltage availability in 208-230/60/1.

•Stackable cabinets.

•Extended range operation (20-120°F EWT) and flow rates as low as 2.25 gpm per ton (geothermal closed loop operation).

•Circuit breaker protected loop and hot water generator pumps.

•Field selectable low temperature cut-out selection setting for geothermal closed loop operation.

•Easily accessible electrical box for wiring.

•Weather-resistent cabinet.

•Internally-mounted (field installed) Flow Controller

•Precharged refrigerant circuit with backseating service valves for quick installation.

Operating Efficiencies

•ARI/ASHRAE/ISO 13256-1 ratings for heating COP’s, cooling EER’s and low water flow rates.

•Operating and temperature range allow shorter loops.

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

•Rugged, super quiet, and highly efficient scroll compressors (rotary for size 018).

•Oversized coaxial tube water to refrigerant heat exchangers operate at low liquid pressure drop.

•Convoluted copper (and optional cupronickel) water tube functions efficiently at low-flow rates and provides freeze-damage resistance.

Service Advantages

•Removable side and top panels for easy access to water/refrigerant circuits.

•Low ambient temperature switch activates loop pump in extreme temperatures.

•Solid state digital compressor module provides reliable lockout, diagnostic, and time delay functions.

•High side loss-of-charge sensing reduces nuisance low pressure faults.

•LED Fault and status indication with memory for easy diagnostics.

•High and low pressure service ports in the refrigerant circuit.

•Refrigerant sensing freeze protection for more accurate low temperature cut-out.

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.

•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, compressor springs, insulated compressor compartment, and interior cabinet insulation using 1/2” coated glass fiber.

•Safety features include: high pressure and loss of charge to protect the compressor; condensate overflow protection; low water temperature limit 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.
