Carrier is known for its high quality engineered heat pumps, air conditioners, and other air quality devices. The Carrier 50 PT Aqua Zone Two Stage Water Source Heat Pump gives one the option of a heat pump not entirely cooled by refrigerants. The unit comes conveniently available in a horizontal installation, a vertical installation, and even a down flow installation format, which gives the user options depending on what type of space he or she has set aside for the Carrier 50 PT unit. Along with water cooling, the unit uses Puron, a proprietary blended refrigerant that combines with a hot water reheat to provide the user with economical efficiency that meets and exceeds most state and federal standards. This model can be installed in existing structures that are being renovated or new construction. For those desiring to attain LEED certification, this Carrier unit is aptly usable for almost all geothermal projects and applications.
Features
The Carrier 50 PT Aqua Zone Two Stage Water Source Heat Pump comes with a number of features that make it one of the world’s most popular brands of heat pumps. Along with utilizing the Puron refrigerant, it has the capacity to function as a two, three, four, or even a five and a half ton system, which makes it suitable for a number of commercial applications. The Puron refrigerant is also labeled as ozone friendly and categorized as the newer R-410 coolant. The unit incorporates a two stage scroll compressor. The compressor is mounted on vibration isolator springs, which are computer selected for each individual unit. It utilizes a water loop boiler that is active between the ranges of 20 to 110 degrees Fahrenheit for optimum air cooling and heating efficiency. An option for the consumer is that of an extended range package for geothermal applications and open loop usage. This is a factory option the consumer decides on during the time of purchase. Another factory option that is available prior to purchase is the modulating hot water reheat that is equipped to monitor performance that makes sure the heat pump is functioning at its most efficient levels. The unit is also ISO certified as well as part of the Energy Star certification.
Reliability
Like all Carrier products, the Carrier 50 PT Aqua Zone Two Stage Water Source Heat Pump is constructed of the highest quality materials. Galvanized construction of the finest steel make up the bulk of the unit while stainless steel covers the condensate pan to ensure no oxidation occurs. A factory option worth considering is the E-coating on all of the coils to prevent any corrosion, which will give the unit many lasting years of service. The unit comes with eight mechanisms of safety:
• Random start delay
• Anti-short cycle
• High/low refrigerant pressure protection
• Condensate overflow sensor
• High/low voltage protection
• Automatic intelligent reset
• Water coil freeze protection
• Air coil freeze protection
As with all Carrier units, the product is shipped with validation that it has been both inspected and tested.
Maintenance
The Carrier 50 PT Aqua Zone Two Stage Water Source Heat Pump is very easy to maintain as it has three exposed access panels in the event a setting should need to be adjusted. When it is time for the unit to be serviced, there are removable front and side panels that are large enough for plenty of working room. The control box is also situated in a convenient area and is easily removed for servicing as well. Filter changes are relatively simple as there are no tools required and can be easily accomplished by non service personnel if the case should arise.
Warranty
All Carrier products are warranted although there are different warranties on different parts. These units carry a one year warranty on the unit itself along with a five year warranty on the compressor, which is normally the most expensive replacement part on the unit. Most dealers will also offer extended factory warranties at a fair price.
Price
Prices on the Carrier 50 PT Aqua Zone Two Stage Water Source Heat Pump will differ from state to state as there are taxes, environmental fees, and other applicable costs that will adjust the price. However, most unit prices are relatively stable. Because these Carrier units come in multiple sizes, one should expect to pay a higher price for increased tonnage. On average, a direct cost from the factory for a four ton unit will run the consumer $4500 to $5500. However, one should keep in mind that there are a number of factory options as up-grades. These up-grades may increase the price as much as $2000 per unit.
