What's New with Bryant Geothermal's GT-PG?

Puron® Refrigerant

Puron® is a non-chlorine based (HFC-410A) refrigerant, that with R-407C and R-134A, is seen as the future of all refrigerants used worldwide. HFC-410A characteristics compared to R-22 are:

Binary and near azeotropic mixture of 50% R-32 and 50% R-125.

Higher efficiencies (50-60% higher operating pressures)

Zero ozone depletion potential and low global warming potential.

Virtually no glide. Unlike other alternative refrigerants, the two components in HFC-410A have virtually the same leak rates.Therefore, refrigerant can be added if necessary without recovering the charge.

MERV 11 2” Pleated filter All GT-PG units include a factory

installed 2” filter rack/duct collar

with a 2” pleated high efficiency MERV 11 air filter.The MERV (minimum efficiency reporting value per ASHRAE Standard 52.2) design features ultra low velocity (<300

fpm) for extended filter life, low pressure drop (0.13 – 0.18 in. wg.) and high particulate efficiency (size E1=41%, E2=69% and E3=87%). The pleated design and low velocity combine to allow the filter to store a large amount of dirt and result in a practical replacement life of up to 6 months.

Tin-Coated Air Coil

All Bryant Geothermal GT- PG Series models feature a tin-coated air-coil.This coating process will provide years of protection against corrosion from airborne chemicals resulting from modern building material out gassing and most environmental chemicals found in the air. Modern building materials such as counter-tops,

floor coverings, paints and other materials can “outgas” chemicals into the home’s air. Some of these chemicals are suspected of contributing to corrosion in the air coils found in both traditional and geothermal heating and cooling equipment. Corrosion often results in refrigerant leaks and eventual failure of the air coil costing hundreds of dollars to replace. Studies have also shown that these air coil coatings improve moisture shedding and therefore improve a unit’s moisture removal capability resulting in a more comfortable home.The GT-PG Series is your assurance of both maximum air coil life and comfort.

Copeland Scroll Compressor

There’s a reason 9 out of every 10 scroll compressors installed are Copeland.With over 15 years of painstaking R & D and rigid production controls, Copeland is able to build the most reliable, efficient and quiet scroll compressors in the world.

The concept of compressing a gas by turning one involute form – or “scroll” – against another around a common axis is nearly a century old. It wasn’t until the late 1980s, however that one company –

Copeland – turned theory into practical reality, using sophisticated, computer-assisted design and manufacturing methods to achieve the critical tolerances required. In the years since, Copeland has become the leader in scroll compressor applications, with nine scroll manufacturing facilities on three continents and millions of units installed worldwide.

Copeland Scroll compressors employ two identical, concentric scrolls, one inserted

within the other. One scroll remains stationary as the other orbits around it.This movement draws gas into the compression chamber and moves it through successively smaller “pockets” formed by the scroll’s rotation, until it reaches maximum pressure at the center of the chamber.There, it’s released through a discharge port in the fixed scroll. During each orbit, several pockets are compressed simultaneously, so operation is virtually continuous.

Recently, Copeland produced its 500,000th Scroll compressor with the environmentally sound refrigerant HFC-410A. Field results have shown that HFC-410A units with Copeland Scroll compressors offer nearly 30% lower failure rates versus existing R-22 units. HFC-410A units can reach the industry’s highest efficiency levels. HFC-410A scrolls also offer sound advantages to other compressor technologies, typically operating several decibels quieter than comparable R-22 models.The result is unsurpassed reliability and virtually silent operation.

Other New Features

Powder coated cabinet, taupe metallic.

Liftout handles for front access panels.

Corrosion and stain resistant stainless steel drain pan with extra slope designed in.

Factory mounted filter drier for trouble free reliability.

Easy access low profile horizontal control box.

Double isolated compressor for quiet and vibration free operation.

Foil faced insulation in air handling compartment to allow easy cleaning and prevent microfiber introduction into the air stream.

Open Service-Friendly Cabinet ( i.e, all components in compressor section can be serviced from the front).
